SEVERE WEATHER TOMORROW (February 16, 2023)
- Tomorrow will be an active weather day across much of the Deep South.
*Tornado Threat: As for South Alabama, an elevated tornado risk will set up tomorrow as we enter the afternoon-evening hours (especially western portions of AL), with an isolated strong tornado potential (EF2+) becoming possible in these areas. Elsewhere, east of I-65, including south-central and southeastern portions of AL, the threat decreases a bit as we get later into the evening and overnight hours with a lingering conditional tornado threat.
* Strong-perhaps sporadic damaging winds will also be possible embedded within stronger storm cores (This risk is highest across the western half of AL).
*Low-end large hail threat exists for west-central into portions of southwest AL; however, this risk is near zero for the remaining portions of South Alabama.
Quiet for now, however, strong- severe storms are on the horizon, and will be impacting South Alabama as we enter the overnight hours into Wednesday morning.
IMPACTS:
* Strong gradient winds will be capable of producing upwards of (30-40 mph gusts) even outside of severe storms periodically throughout tonight into tomorrow morning.
* Sporadic pockets of strong to damaging winds will also be possible within stronger storm cores (50-70 mph gusts) as the squall line proceeds from southwest AL to southeast AL.
* A Tornado threat exists for immediate southwest portions, including Mobile, Baldwin, Washington, Clarke, Monroe, Conecuh, Escambia, and Covington counties. The danger of a strong tornado (EF-2+) may also become possible in these areas, especially in the panhandle of FL, where conditions are more supportive of development.
* Hail Threat is very low, but not zero, so isolated pockets of hail may be possible in stronger cores.
SEVERE WEATHER EARLY AFTERNOON-EVENING HOURS TODAY:
The ongoing threat of severe weather associated with a cold front has already produced severe storms in northwestern AL, including multiple severe thunderstorm warnings and even a couple of tornadoes. As the squall line continues to accelerate to the south and east throughout early afternoon-evening hours across South AL, it will bring the same impacts.
IMPACTS
-STRONG WINDS: Most prevalent risk is strong-perhaps damaging wind gusts possible within stronger storm cores capable of producing (65+ mph gusts).
-SPIN-UP TORNADOES: Within this squall line, discrete supercells may also develop; and a low risk in which a strong tornado may be possible.
-HAIL POSSIBLE: Hail is also possible within a more potent cell, and can’t fetch out that large hail may also be possible (1-1.5 in diameter).
TIMING
- SOUTHWEST AL: Roughly 11-3 pm
- SOUTHCENTRAL AL: Roughly 2-5 pm
- SOUTHEAST AL: Roughly 4-6pm
Fresh 16Z HRRR 3km model run showing significant tornado parameter values that are quite concerning. Not only indicative of a high likelihood of tornadic development but also the ingredients aligning for strong-long track violent tornadoes also being possible throughout southwest portions of Alabama today.
Rainy+breezy day TOMORROW: Currently, as of tonight, we have #HurricaneNicole, which is barreling down on the eastern coast of FL making landfall sometime tonight. Here locally, we will start to feel the effects from Nicole beginning tomorrow afternoon, as the outerbands will filtrate in as the centered low pressure of Nicole inches closer towards the FL panhandle into GA.
**The impacts you can expect here locally tomorrow afternoon-tomorrow night will vary on location**
-Southeastern AL: Rainfall totals: 1.50”-2.00”+with max wind gusts (35-45mph) being possible at times.
-Southcentral AL: Raindall totals: 0.50”-1.00” with max wind gusts (30-35 mph) being possible at times.
-Southwest AL: Rainfall totals: 0.00”-0.50” with max wind gusts (20-30 mph) being possible at times.
Future "Feel Like" temps tomorrow morning! So, are you ready for the downright cold temps when walking out the door tomorrow morning?! Brrr🥶
Rain & Storms TOMORROW: Tomorrow South Alabama will break the dry spell after nearly four weeks of not seeing a trace of rain in sight!
-Future Radar below shows a robust coverage of shower and storm activity throughout the day tomorrow. Many will receive anywhere from (1/2 of an inch to 2 inches of rain).
