**THURSDAY CLIPPER // ACCUMULATING SNOW**

A potent clipper system will dive southeast from Alberta, Canada, into the Northern Plains and Minnesota leading to a round of wintry weather on Thursday.

🔴A vigorous shortwave trough (disturbance), or clipper system, will sweep across the area on Thursday. A surface low pressure will also develop in the Northern Plains and push southeast through southern Minnesota into central Iowa through the day.

🔴Ahead of the system, low-level warm air advection will occur leading to vertical motion and rising air resulting in precipitation developing on the east-to-northeast side of the surface low. Temperatures throughout the atmospheric profile are expected to be below-freezing so snow will be the main precipitation type.

🔴Snow will likely develop sometime around or before daybreak on Thursday with snow showers continuing through much of the day. The heaviest, or bulk, of the snow will likely occur during the morning before wrapping up around lunchtime or in the early afternoon hours. A trailing shortwave will usher in cold air advection and help squeeze out the remaining moisture with snow showers likely continuing into the evening hours.

🔴There have been notable shifts (south and north) in recent weather model runs over the last day or so as the storm system continues to wobble around most likely because the storms' energy is still off the Pacific coast. Once it makes it onshore, the National Weather Service's weather balloon network can sample its data and ingest it into the models with hopefully a clearer and more high confidence track can be narrowed down. Just subtle differences in the storm track can make a big difference in who may see several inches of snow to very little.

🔴Snow accumulation is looking likely as this system has fairly strong dynamics and moisture to work with. The 24-hour probability of at least 2" of snow from Thursday morning to Friday morning is around 40-80% across southeast Minnesota and below 40% across north Iowa. The probability of at least 4" of snow is >40% near and north of Red Wing into east-central Minnesota and western Wisconsin. So, this is a good start and the snow forecast will likely become clearer in the next 12-24 hours.

Be prepared for a slippery Thursday morning and evening commute! 🚗❄️

[TUES. 2:56 PM] - **UPDATE**

There have been reports of freezing rain/drizzle across portions of north Iowa where several vehicle accidents including jackknifed semis have occurred on I-35 in Cerro Gordo county. Stay safe and take it slow if traveling across north Iowa!

[TUES. 1:50 PM] - **RADAR UPDATE**

Light snow continues to move across north Iowa and portions of southwest-southern Minnesota. There has been a more southerly trend with the snow than what was originally thought this morning.

Areas near/south of I-90 have the best chance to see accumulations of around 1" (locally higher up to 2" possible), whereas further north very little, if any is expected. Roads will quickly become snow covered and slippery so safe travels if you're going to be out and about.

📸MnDOT: MN 60 at Mountain Lake.
📸MnDOT: I-90 at Welcome.

12/17/2024

**TUESDAY FORECAST** (December 17, 2024)

Light snow likely this afternoon and evening. Amounts will vary from 0.5" to around 2" across southeast Minnesota and north Iowa. More snow.. and accumulating.. looking likely on Thursday followed by another brief cooldown into the weekend!

12/17/2024

[TUES. 9:55 AM] - **RADAR UPDATE**

🔴Snow is pushing into northwest Iowa and far southwestern Minnesota this morning. Light accumulations and lower visibilities are evident by various DOT road cameras in Iowa and Minnesota. Roads are also partially snow covered and may be slippery!

🔴Expect snow to move into north Iowa and southeast Minnesota around lunchtime into the early-to-mid- afternoon hours lasting until late evening. Slippery roads and surfaces will be likely!

**TUESDAY SNOW // LIGHT ACCUMULATIONS LIKELY**

A quick-moving system will deliver a round of snow Tuesday with some light accumulations likely.

🔴A shortwave trough (disturbance) is poised to swing across the area on Tuesday. Vertical motion and rising air ahead of the trough will lead to precipitation developing. Meanwhile, a surface low pressure will track east from the Central Plains into Missouri while a high pressure system builds in from the northwest bringing down colder Canadian air. Between the two systems there will be a sharp temperature gradient, or baroclinic zone, which are favored areas where storms like to intensify and where precipitation can form. In this case, the cold air in place will lead to snow as the main precipitation type.

🔴This system doesn't have a lot of moisture to work with, but will still put down some light snow accumulations. Look for snow to move into southern-southeast Minnesota and north Iowa after lunchtime into the early-to-mid- afternoon. Snow is expected to wrap-up by late evening around midnight or so.

🔴Snow accumulations of around 0.5" to 2" are possible across southeast Minnesota and north Iowa. Higher amounts of 2"+ is likely across far southwestern Minnesota. Temperatures are expected to be in the 20s to 30° so snow sticking to roads will be likely so plan on some possible slippery spots. There could also be lower visibility under the snow showers. Drive carefully if traveling!

12/17/2024

Good Tuesday morning!

**TUESDAY AND THURSDAY SNOW LIKELY**

A couple of shortwave troughs (disturbances) will swing through the area this week - Tuesday and Thursday - leading to snow with some accumulations looking likely at his point.

*TUESDAY SNOW*

🔴A shortwave trough will track across the region. At the surface, an area of low pressure will develop and push to the south across the central plains into the mid-Mississippi River Valley region. Cold air will follow and build in on the northern side ahead of a Canadian high pressure system nudging in from the north. That'll lead to a fairly tight "baroclinic zone", or a compact temperatures gradient where storm systems can often intensify. It's this zone where snow will be likely. Also, the area will be in a zone of upper-level divergence, which enhances vertical motion and lift in developing precipitation, within a strong 110-120+ knots upper-level jet stream.

🔴Snow will most likely develop sometime after lunch in the afternoon and continue through much of the day before ending sometime late in the evening. It's not going to be a *heavy* snow per say. Snow ratios are expected to be around 10:1 to 15:1 with snow becoming more *light* and fluffy through the day.

🔴Snow accumulations of around 1-2" is looking possible mainly near and north of I-90. A band of 2"+ is possible further west across portions of southwest Minnesota. Temperatures are expected to be in the 20s so snow should have no problem sticking to roads and other surfaces.

*THURSDAY SNOW*

🔴A more potent clipper system will dive southeast from the northern plains into southern Minnesota and northern Iowa. Snow will develop and push across Minnesota from northwest to southeast likely arriving in southeast Minnesota sometime in the late morning to early afternoon.

🔴There is still some uncertainty in the track of this system which will be key in where the heaviest snow accumulations fall. Many of the medium-to-long- range models are showing a variety of accumulations which again, will be tied to the storm track. These details will better come together in the next 24-hours when the storms' energy makes it ashore over the Pacific coast.

🔴As of this morning, the higher snow accumulations (3"+) are expected to be confined to north-central Minnesota, however some new data is shifting the system a bit further south. So, that may be a new trend to watch and if so, the higher accumulations would also shift more toward southern Minnesota. The probability of at least 1" of snow is 40-80% from north Iowa into southern Minnesota with the higher probabilities in Minnesota.

Dust off the shovels... they may be needed this week! ❄️☃️

12/16/2024

Good Monday morning!

We're off to a foggy start to the week! The fog will clear up around midmorning. I'm tracking TWO chances for snow this week - so dust off the shovel - and another big cooldown by the weekend!

We're LIVE on-air and online until 7:00 AM!

WATCH LIVE: https://www.kaaltv.com/live/

12/15/2024

[SUN. 11:15 AM] - **DENSE FOG ADVISORY** remains in effect for far southeast Minnesota and northeast Iowa along with adjacent areas east and south until early Monday morning.

🔴Visibility at times may drop to 1/4 of a mile or less. Don't forget to use your low-beam headlights.

🔴Temperatures are expected to be hovering around the freezing mark (32°F) Sunday night into Monday morning, so there's the potential of "freezing" fog which may lead to some slippery spots especially on any untreated surfaces!

12/14/2024

[SAT. 8:46 AM] - **RADAR UPDATE**

A band of freezing rain, sleet and snow is making its way from northeast Iowa into southeast Minnesota. Roads and untreated surfaces will likely become slippery so use caution if traveling.

12/13/2024

**FREEZING RAIN, WINTRY MIX & HAZARDOUS TRAVEL LATE FRIDAY AND SATURDAY**

A storm system will slide across the region beginning late Friday night lasting through much of Saturday bringing a mess of wintry precipitation and likely hazardous travel conditions.

🔴A low pressure trough will scoot east from the southwest U.S. to the mid-Mississippi River Valley region today through Saturday. Meanwhile in response, a surface low pressure system will develop in the southern/central plains and push northeast along the Missouri and Iowa state line.

🔴Moisture will transport northward from the Gulf of Mexico into the region as the system makes its move toward the area. This will set the stage for a variety of precipitation types including freezing rain, sleet, snow and rain.

🔴Surface temperatures are expected to be in the teens and 20s locally late Friday night into Saturday morning. Meanwhile, temperatures 5,000 to 10,000 feet higher in the atmosphere will eventually rise above the freezing mark (32°F) as the system's southerly winds pull in warmer air and moisture.

🔴Precipitation is likely to develop sometime around or after 10:00 PM in north Iowa and 2:00 AM in southeast Minnesota. This will likely start as a wintry mix of freezing rain (possible sleet) in north Iowa while the atmospheric column may be all below-freezing in southeast Minnesota that it start as snow, however as warmer air builds in aloft, a wintry mix of freezing rain & sleet would be possible.

🔴A wintry mix of freezing rain, sleet and possibly some snow will continue throughout much of Saturday. Surface temperatures may get to near the freezing mark as the day moves along, but I wouldn't be surprised if they stay below-freezing meaning the wintry mix will continue to be the main precipitation type. If surface temperatures can manage to get to above-freezing, some rain would be possible, but that looks more likely to occur across portions of northeast and eastern Iowa.

🔴As the system pulls away from the area on Saturday evening, colder air is expected to wraparound its backend likely leading to a colder temperature profile and mainly snow with some accumulations.

🔴WINTER WEATHER ADVISORIES are posted across all of southeast Minnesota and north Iowa beginning Friday night and lasting until at least Saturday evening. Ice accumulations of around 0.05" to 0.15" are possible along with snow accumulations around 1" or less.

🔴ICE STORM WARNINGS are in effect for portions of east/central Iowa where significant icing (up to 0.30") and gusty winds will create very hazardous if not impossible travel in that part of the state. Power outages and downed tree limbs are also likely.

🔴Travel will become extremely difficult locally beginning late Friday night and lasting through much of Saturday. Any untreated surfaces such as roads, parking lots, sidewalks, etc. will be greatly impacted. IF you must travel, take the main highways, but they may even have some slippery stretches! STAY SAFE!

12/12/2024

**WINTRY MESS POSSIBLE SATURDAY**

A storm system will sweep through the area late Friday through Saturday likely bringing a mixed bag of precipitation which could lead to some tricky travel.

🔴A shortwave upper level trough will scoot east from the west coast through the central plains and into the mid-Mississippi River Valley region heading into the weekend. The system will draw northward moisture from the Gulf of Mexico. As it gets closer, vertical motion and rising of air parcels will lead to clouds and precipitation developing.

🔴A surface low pressure will develop and is expected to track from the central plains and pivot across the Iowa and Missouri state line into southeast Iowa by Saturday night. A warm front will lift north, but will only make it to eastern Iowa due to high pressure situated over the Great Lakes. North of the front, colder air will lead to a mixed bag of precipitation including freezing rain, sleet and snow.

*PRECIPITATION TYPE*

🔴This is the tricky part as one or two degrees in temperatures can mean the difference between freezing rain, sleet, snow and rain. The system will pull warmer air north into the region, however, the warmer air will mostly be confined in the upper part of the atmosphere around 5,000 to 10,000 feet. At the surface, temperatures are expected to be below the freezing mark and likely in the 20s. As precipitation falls through the warmer layer aloft, it'll melt to rain, however as it encounters the colder air at the surface, it'll refreeze. If the colder air at the surface is fairly shallow, the raindrop won't have time to fully refreeze into snow, therefore will freeze on contact with subfreezing surfaces resulting in ice. If the cold air at the surface is a little deeper, the raindrop will refreeze a bit more, but into ice pellets, or sleet.

🔴It's possible precipitation begins to develop overnight Friday or early on Saturday morning. Model data is pointing at this being a wintry mix of freezing rain, sleet and possibly snow. As the system scoots further east into Saturday, more colder air wrapping around the backend could very well change any mixed precipitation to snow. Further south across Iowa and near the warm front and surface low, temperatures may be warm enough for rain.

*FREEZING RAIN // ICE*

🔴Freezing rain accumulation of around 0.05" o 0.10" is possible across southeast Minnesota and northern Iowa which would likely leave a glaze of ice on untreated surfaces such as roads, parking lots, sidewalks, etc., likely resulting in some tricky travel.

*SNOW*

🔴This is where the greatest uncertainty exists. If freezing rain and/or sleet hold on for longer, that would ideally cut down on snow potential. But, it's possible if enough colder air can wraparound the system that a change to snow would be possible. By then, the bulk of the moisture will be further east so any snow amounts at this time are looking light and around 1" or less.

Bottom line.. Saturday is looking rather messy with slippery stretches on roads likely. Make sure to stay updated on the forecast.

**TUESDAY FORECAST** (December 10, 2024)

Wintry weather is back on the table with light snow tonight into Wednesday morning with minor accumulations, and bitter cold Arctic air settling in over the next couple of days.

12/10/2024

**LIGHT SNOW TONIGHT // ARCTIC AIR RETURNS**

Arctic air is set to return to the area for a brief stay. Before it settles in, light snow will be likely tonight with some minor accumulations likely.

*LIGHT SNOW TUESDAY NIGHT*

🔴Snow will likely develop across western Minnesota late in the afternoon and push east eventually getting into southeast Minnesota and portions of north Iowa by late evening with the bulk of it falling overnight before wrapping up around or before sunrise on Wednesday morning.

🔴This will not be a major storm, but a quick-hitting round of light, fluffy snow. Accumulations up to 1" are possible across much of the area. The wind will pickup behind the system with gusts up to 30 mph which may lead to some areas of blowing snow. Temperatures will be plenty cold in the teens. As a result of the above mentioned, snow shouldn't have a problem sticking to roads with slippery spots likely especially for the Wednesday morning commute!

*ARCTIC AIR RETURNS*

🔴WEDNESDAY: Bitter cold Arctic air will arrive and begin to settle in overhead. Temperatures are expected to be in the teens during morning (which will be the high for the day) and will fall into the single digits by afternoon as the cold air surges into the area. Wind chills will also fall below-zero as a brisk northwest wind will gust up to 30 mph at times.

🔴THURSDAY: This will the coldest day of the season so far. Temperatures are expected to be in the single digits below-zero to start the day with wind chills in the teens to 20° below-zero! Despite sunshine, high temperatures are expected to only manage the single digits above-zero. The wind will be much lighter.

🔴FRIDAY: The Arctic cold will begin to lift out. The day will start plenty cold with temperatures in the single digits above-zero. Highs for the day are expected to climb into the lower 20s which is still around 10° or so below-average.

Bottom line.. be careful and take it slow on the Wednesday morning commute, and also dress very, very warm!

**TUESDAY FORECAST** (December 17, 2024) Light snow likely this afternoon and evening. Amounts will vary from 0.5" to around 2" across southeast Minnesota and north Iowa. More snow.. and accumulating.. looking likely on Thursday followed by another brief cooldown into the weekend!

[SAT. 8:46 AM] - **RADAR UPDATE** A band of freezing rain, sleet and snow is making its way from northeast Iowa into southeast Minnesota. Roads and untreated surfaces will likely become slippery so use caution if traveling.

[WED. 6:45 AM] - **RADAR UPDATE** Snow showers continue to push east into far southeast Minnesota, northeast Iowa and southwest Wisconsin. A light coating of snow on roads is likely with some slippery spots. Pockets of light snow and flurries are possible heading into the afternoon.

**TUESDAY FORECAST** (December 10, 2024) Wintry weather is back on the table with light snow tonight into Wednesday morning with minor accumulations, and bitter cold Arctic air settling in over the next couple of days.

**FRIDAY FORECAST** (December 6, 2024) The weekend will bring a big boost in temperatures as mild weather for early December is expected. BUT, as usual this time of year, it won't last as a another big cooldown comes by the middle of next week.

**THURSDAY FORECAST** (December 5, 2024) Arctic air will loosen its grip on the area heading into the weekend as its replaced by mild Pacific air leading to a nice bump in our temperatures. But, that won't last very long either, and is there any snow in the days ahead?

**TUESDAY FORECAST** (December 3, 2024) Light snow/flurries are possible on Wednesday along with strong winds. Thursday is looking really cold, but it won't last as temperatures are expected to warm well above-average through the upcoming weekend.

**MONDAY FORECAST** (December 2, 2024) The snow from this morning is long gone! The rest of the week is shaping up to be fairly quiet with little chances for precipitation. The bigger story is the up-and-down temperatures swings that are expected all the way through the weekend!

[MON. 7:55 AM] - **RADAR UPDATE** ❗️Light snow and flurries continue to track southeast this morning. Accumulations are expected to be very light (dusting to 0.5"), but just enough to cause slippery stretches on roads, bridges, overpasses, etc.. ⚠️Use caution when traveling! Always drive to the weather conditions.

**FRIDAY FORECAST** (November 29, 2024) Arctic air in place will lead to a very cold weekend ahead! The cold will ease heading into next week with small snow chances over the next week or so.

**LAKE-EFFECT SNOW TO BURY SOME GREAT LAKES COMMUNITIES** A major lake-effect snow event is underway across the Great Lakes states as several inches and even... feet... of snow is expected for some. 🔴Cold, Arctic air is descending south over the region and flowing over the relatively "warm" waters of the Great Lakes. As the cold air passes over the waters, it rises, clouds form, and grow into narrow bands that produce snow which can be heavy at times. 🔴Thundersnow can lead to snowfall rates of 2-3" per hour, or higher, is possible in some of the more intense bands which can mean several inches, or even feet, of snow for some communities by the time it's all done. 🔴Blizzard conditions will be likely in some of the stronger bands of snow most likely closing off sections of major highways and interstates across the region. Meanwhile, outside of the heavier snow bands, only flurries or a clear sky are sometimes the case, which can lead to a false sense of security or create dramatically different conditions from one mile to the next. 🔴Storm total snow accumulation of 1-2 feet is expected in Orchard Park, New York, which is home to the NFL's, Buffalo Bills, who are scheduled to have a home game vs the San Francisco 49ers at 7:00 PM on Sunday night.

**WEDNESDAY FORECAST** (November 27, 2024) A clipper will move through the area today with light snow or flurries for some. More flurries or a brief snow shower is possible on Thanksgiving Day, but the bigger story is the cold air that will arrive heading into the weekend! 🥶
