What an afternoon & evening it has been in central Illinois! At least 15 reports of tornadoes, hail up to golfball size & a measured wind gust of 75 mph at the Springfield Airport!
Some of these areas received 8" of snow last weekend & dropped to the single digits this week!
Key to this today was sun. Sun warmed these areas to 60-65 in a strongly shear, dynamics environment with cold air aloft.
That...........after this lastnight-early this morning:
The Tornado Watch as been eroding away as the storms march eastward. As of the moment there is still a Tornado Warning for cell just east of Bloomington, Illinois.
Here, we just could shake the low clouds, except for a few breaks & most of those were brief & in the southwestern half of the area.
It is warming up over the area. Temperatures as of 8:22 p.m. are 46-58 (northeast to southwest) over the area right now, with 55-57 over Greater Lafayette.
One band of showers & a few t'storms is moving northeast away from the area, but arc of showers & t'storms that has produced all of the severe weather is approaching.
It is weakening due to lack of heating, but there is still a lot of shear present & forcing. So, a few showers & t'storms will race through within the next several hours. An isolated severe t'storm cannot be ruled out.
Temperatures should max out at 54-60 over the area.
Overnight, any rain with exit with breezy to windy conditions & 40s, followed by 50s with some dry weather, then afternoon showers/t'showers tomorrow. Temperatures will begin to fall into the 40s. It will be a breezy to windy day.
We get in on some snow Sunday night to Monday, Monday night to even Tuesday. Minor accumulations are possible with 1" or less at times with 1-2" amounts possible in the north. The most widespread, most steady snow looks to be Monday morning. It looks more like snow showers & squalls beyond that. However periods of some slick travel are possible Sunday night to Tuesday.
Additional snow possible late next week & next weekend. Looks like a good pattern for a winter storm, but details this far out are sparse. Good set-up though.
