10:15 a.m. | MON. DEC. 8 | - **ACTIVE WEATHER WEEK**

This active weather pattern which really began right after Thanksgiving, will continue this week with multiple chances of precipitation.

MONDAY EVENING: A clipper system will pass through North-Central Minnesota and may graze the southeast portion of the state with some light snow. Mainly between 7:00 and 10:00 p.m. Accumulations are looking minor, if any.

TUESDAY-WEDNESDAY: A stronger clipper will once again pass through the Upper Midwest. This one is a little more complicated due to the temperture profile. A wintry mix (freezing rain, sleet, snow) is possible initially by early afternoon as temperatures may be hovering near or slightly below the freezing mark (32°). As temperatures warm into the middle 30s through the afternoon, any wintry precipitation should change to rain with some possible snowflakes at times. Colder air will build in behind the system changing any rain back to snow late Tuesday night into Wednesday morning. Accumulations near 0.5" or less are possible.

Areas along and north of I-94 will likely see several inches of snow (4-7"+) and where **WINTER STORM WATCHES** are in effect.

The wind will also increase Tuesday night into Wednesday with gusts up to 40-45 mph at times which may lead to blowing snow in open/rural areas.

THURSDAY & FRIDAY: Additional clipper systems are expected to pass through in the northwest upper-air flow. There is still quite a bit of uncertainty on the track of each and their associated features, but certainly more snow is possible.

2:25 p.m. | FRI. DEC. 5 |

A **WINTER WEATHER ADVISORY** is in effect for areas along and south of Highway 14 in Southeast Minnesota along with several counties in North and Northeast Iowa from 3:00 p.m. on Saturday until 6:00 a.m. on Sunday. Snowfall accumulations of 2-5" are possible which will lead to slippery and slushy roads.

Meanwhile, a **WINTER STORM WARNING** is in place for portions of central and northwest Iowa where 4-7" of snow is possible.

12:37 p.m. | FRI. DEC. 5 | - **SHOVELABLE SNOW SATURDAY**

A potent clipper system will push through the area on Saturday bringing another round of snow followed by a brief blast of cold on Sunday.

The first half of Saturday will be quiet with some sunshine possible during the morning hours before clouds build into the afternoon as the clipper approaches. Temperatures are expected to be in the upper teens to near 20° for highs.

This system will have a lot more energy and moisture than Friday's system which will help produce accumulating and shovelable snow for the entire local area.

Snow will develop sometime during the middle or late afternoon hours (3-5:00 p.m.) before becoming more widespread through Saturday evening. The snow will taper off early in the overnight hours into Sunday morning. Slippery roads and other surfaces will be likely so use extra caution when traveling.

Snowfall accumulations of 2-5" are likely for most across Southeast Minnesota with higher amounts of 4-7" possible across North Iowa where a **WINTER STORM WATCH** is in effect from 6:00 p.m on Saturday until 6:00 a.m. on Sunday.

**DISCLAIMER: This storm is still coming together so any shift north or south could alter the amounts and where**

Behind the system, a brief blast of cold will settle in on Sunday as high temperatures are expected to range from the upper single digits to lower teens. The wind will be light out of the north, but enough to produce wind chills in the range of -5° to 5° throughout the day.

10:17 a.m. | FRI. DEC. 5 | - **WINTER STORM WATCH**

The National Weather Service in Des Moines, IA has issued a **WINTER STORM WATCH** for portions of North and Central Iowa from Saturday evening until early Sunday morning.

Snowfall of 4-7" is possible in these areas. If the storm were to shift a bit further north, it's likely these could be expanded, but that remains to be seen.

9:13 a.m. | FRI. DEC. 5 | - **LIGHT SNOW FRIDAY**

A quick-moving clipper system will pass through the area today. It doesn't have a lot of moisture to work with, but just enough along with ample energy to produce light snow beginning this morning and lasting until early evening.

A push of colder air tonight may lead to additional light snow showers through the night.

Accumulations are looking light with around 1.0" or less near and north of I-90. A dusting, if anything is expected further south.

Not a big snow producer, but could still lead to some slippery/slushy spots on roads.

10:17 a.m. | THU. DEC. 4 | - **SNOW POTENTIAL LATE SATURDAY**

There is starting to be some better agreement within model data on the track of a clipper system that will bring the potential of accumulating snow to the region on Saturday.

Much like Friday, this system will track across the Northern Rockies and dive southeast into the Central Plains and west-central Iowa by late in the day on Saturday and Saturday night. This one is a little more amplified (stronger) and will also have more moisture to work with.

The exact track is still wobbling around and will be crucial in where any heavier snows fall, but there's starting to be consensus within data that region may be from far southwest Minnesota into north-central Iowa - maybe even far southern Minnesota.

Short-term model data will begin to come into play today and tomorrow when more of a consensus will likely be reached, but much of Southeast Minnesota and North Iowa could see some accumulations.

9:38 a.m. | THU. DEC. 4 | - **LIGHT SNOW LIKELY FRIDAY**

A quick-moving clipper system will track across the Northern Rockies and dive southeast into Minnesota on Friday.

Moisture isn't overly impressive with this system, but there will be just enough along with some modest energy to produce light snow. It'll likely arrive sometime during the midmoring hours until late afternoon. A few snow showers will be possible Friday evening as a push of colder air arrives behind the front.

Accumulations look to generally stay around or less than 0.50", but still could lead to some slippery spots as temperatures will be in the 20s.

11:28 a.m. | WED. DEC. 3 | - **SNOW POSSIBLE SATURDAY NIGHT**

I'm still watching the potential of accumulating snow on Saturday night.

A clipper system is expected to cross the Northern Rockies and dive southeast into the Central Plains late in the day on Saturday. There is still quite the spread in model data on the track of this system with some pushing it through the local area with snow while others are a complete miss and leave us dry.

As it stands today, there is the potential of accumulations near and south of Highway 14 in Southeast Minnesota into North Iowa.

Short-term model data will begin to come into play tomorrow so more specific details should start to become clearer in the next 24-36 hours.

9:02 a.m. | WED. DEC. 3 - **SUB-ZERO TEMPERATURES**

Thursday will mark the first day of the season that temperatures fall below-zero. It's actually pretty close to being on schedule. The average first date of the season that Rochester typically sees a sub-zero temperature is around December 7th.

In fact, Thursday will be the earliest sub-zero temperature since 2018. That year it occurred on November 18th.

12/03/2025

8:35 a.m. | WED. DEC. 3 | - **ARCTIC AIR INCOMING**

Arctic air will descend into the region today as temperatures plunge into the single digits by early evening. Wind chills will also drop below-zero.

Thursday will be the first day of the season with sub-zero temperatures as they will start around -10° before climbing into the teens above-zero by afternoon. However, wind chills will remain below-zero all day long.

8:10 p.m. | TUE. DEC 2 | - **RADAR UPDATE**

Radar is picking up on snow returns across much of south and central Minnesota and north Iowa. Some of the snow may not be reaching the ground completely as it'll take a bit for the atmosphere to saturate due to some dry air in place.

Light snow will be possible through much of the night as this system passes through. Accumulations are expected to be minor from a dusting to 0.50".

2:42 p.m. | TUE. DEC. 2 | - **ACCUMULATING SNOW POSSIBLE LATE SATURDAY**

A clipper system will dive southeast out of the Northern Rockies and into the region late in the day on Saturday and Saturday night leading to the possibility of accumulating snow.

There is still quite a bit of spread and uncertainty in the operational model guidance with the GFS (American) and ECMWF (European). The GFS is the more southern solution and keeps it a weaker system as it shears (fizzles) out across Nebraska, southern Iowa and northern Missouri. The ECMWF is the furthest northern solution and is a bit stronger. It has a band of stronger dynamics and accumulating snow right across Southeast Minnesota and North Iowa. These two solutions are miles apart. I expect some more clarity in the next couple of days. The track is crucial in where any accumulating snow will fall.

Taking a look at each models respective ensembles, or long-range counterparts. Both the GEFS (American) and EPS (European) have fairly reasonable probabilities of least 1.0" of snow this far out. The GEFS has the higher probability near and south of the I-90 corridor. While the EPS has the higher probability across the entire area.

Still lots to sort out in the coming days, but some snow accumulation is looking promising at this point.
