First Alert Weather Day: Severe storms possible late Tuesday into Wednesday
Another round for storms to occur Tuesday evening across portions of northern and central Wisconsin. Severe storms are possible.
WAUSAU, Wis. (WSAW) - A First Alert Weather Day has been issued for Tuesday evening has we’re tracking chances for severe storms to develop in portions of North Central Wisconsin. A low-pressure system will move across the Upper Midwest Tuesday evening and through the night. A chance for showers and thunderstorms to develop late Tuesday as the low-pressure swings a cold front through. The lifting warm front earlier in the day will fuel the area with possible severe weather ingredients. A cold front moving in for the evening will try to trigger strong to locally severe storms for areas in North Central Wisconsin after 10 PM. The Storm Prediction Center has most of the Badger State under a Marginal (level 1 out of 5) and Slight (level 2 out of 5) Risk for severe weather.
While the slight risk indicates the likely area for thunderstorms to occur, the highest amounts of thunderstorm fuel will remain south of HWY 29 for Tuesday night. Storms will begin to develop ahead of the front in areas NW of HWY 29, likely 7 PM.
These storms still have the chance to become severe. But there is less thunderstorm fuel for storms to work with in this area during that time period. Storm fuel will decrease throughout the night. The traveling cold front will push storms south/southeast as far as areas along HWY 29. Primary threats will include large hail, damaging winds and brief downpours.
The cold front will be strong enough to cause a sharp drop in temperatures beginning Wednesday. Daytime highs will struggle to warm towards the upper 60s. Slight chance for a shower to develop in the Northwoods as the frontal system clears. The First Day of Fall is Thursday, and Mother Nature looks to get into the fall spirit. North-Central Wisconsin could see morning temperatures as low as the mid to upper 30s. Most locations will drop down into the 30s by daybreak Friday, with several areas possibly seeing their first frost of the season. Daytime highs will warm but remain below average in the upper 50s.
