It is rather early spring-like outside with some of that thunder & lightning with rising temperatures. Eerie low, smoky, steam-like dense fog is forming as this warm air rides over ice covered ponds, lakes, creeks, rivers & low-lying areas...........even with a breeze. It was interesting to see this dense fog over a wooded swamp near my neighborhood with the lightning illuminating the sky & trees!
We had had a couple of Severe T'Storm Warnings in Illinois, but none here. I have received a report of pea sized hail from far southeastern Clinton County near Kirklin, however. A few of these t'showers have been quite gusty. A gust of 33 mph was measured at the I-65/28 INDOT weather sensor as t'shower passed & gust of 40 mph was measured near Kirklin. This particular spoke of showers & t'showers continues to pivot northward.
There is still quite a bit of lightning around!
Another spoke of showers & t'showers is pivoting through central Illinois behind the first one around the still deepening surface low. It has dropped 2 mb in 2 hours over northern Missouri to southeastern Iowa from 998 to 996 mb.
This second spoke will pass through with time over the next couple of hours, as well.
Risk of an isolated severe cell is rather low, but NOT zero as surface low will deepen rapidly to 988 mb over the coming hours over northern Illinois to southeast Wisconsin. Impressive pressure rise/fall couplet with bits of elevated CAPE (buoyancy) & impressive dynamics will occur, so I'd like to keep mention of a couple isolated severe gusts &/or brief funnel possible until that second spoke of showers/t'showers passes.
Temperatures will continue to rise, they are rising into the 50-56 range in the southwestern half of the area, but are still running 43-49 in the northeast half.
With 56-60 just southwest of the area, we will likely continue to rise past midnight until actual cold front passes 4-6 a.m.
All that said, again, an isolated severe gust &/or funnel could occur with spoke of showers/t'showers over the next several hours, then wall of 45-60 mph gusts will blast in with passing cold front (again in the 4-6 a.m.) It will pass as a line of howling, gusty showers.
Behind the front, wave of some snow showers will pass, driven by howling, damaging winds. A few local light dustings are possible. mainly on grassy & elevated surfaces.
Clearing is likely in the afternoon, but temperatures will will drop all day from 34 in the morning to 27 by late in the day. Wind chills will drop to around 12 later in the day.
After periods of gusts 45-60 mph (isolated 65 mph) Sunday morning-afternoon-evening, gusts will decrease to 45 mph Sunday night & 35 mph Monday morning.
However, as temperatures drop to 9-15 Monday morning, wind chills will drop to -8 to 0.
Monday may be rather bright & the winds decrease to gusts of 25 mph, highs will only run 25-30 with wind chills staying in the teens all day.
