All Activity

I like the feeling being at the head of the action. It makes me feel like we won't get the shaft, but the south will be on there balls tomorrow.

What's crazy is that we already had a 5" candidate that would also break the record and then got the 6" report. That's one of the most intense thunderstorms on record in IL. Twice setting new state hail records (likely) with a significant tornado just south of the giant hail. Plains type stuff. Definitely feel for everyone affected down there.

Getting the worst lightning storm (frequent, prolific) I've experienced so early currently, just incredible. Its 4C and dropping, DP of 3C. 200+ strikes in 40 mins. 10mm in less than a hr I still have 5-8 inches snow on most grass with large snow piles. I don't know if its Mar 11 or the 12th but 14 years ago about this time I got one of my only severe t-storms since 2010 which crazily may be the only other frequent lightning event so early (kicked off the great March heatwave). I had sizable hail during that one, no hail in this ongoing storm.

In all 3 "zones" of the HWO from last night DAYS TWO THROUGH SEVEN...Wednesday through Monday Multiple rounds of scattered severe thunderstorms are possible, most likely between 2 PM and 10 PM Wednesday afternoon and evening. Severe thunderstorms may be capable of producing damaging wind gusts of 60 to 70 mph, a few instances of large hail, and a couple tornadoes which could even be strong. Monitor the latest forecast for updates and watches, and be sure to have a way to receive warnings promptly. .SPOTTER INFORMATION STATEMENT... Spotter activation will likely be needed Wednesday

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1229 AM CDT Wed Mar 11 2026 Valid 111200Z - 121200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE LOWER MISSISSIPPI VALLEY...ACROSS THE TENNESSEE/OHIO VALLEY INTO THE MIDDLE ATLANTIC... ...SUMMARY... Isolated to scattered severe thunderstorms are expected today from the ArkLaTex and Lower Mississippi Valley northeastward through the Ohio Valley and Mid-Atlantic. ...Ohio Valley/Middle Atlantic... Northern-stream trough is digging east-southeast across the northern Rockies/High Plains early this morning and should advance into the upper MS Valley by 18z as a 500mb speed max translates through the base of the trough, then increases in intensity as it moves across lower MI during the afternoon. Large-scale height falls will overspread the Great Lakes/OH-TN Valley region as southwesterly flow strengthens across the downstream warm sector. Latest model guidance suggests the sharp cold front associated with this feature will extend across lower MI-central IL-northern MO at the start of the period. This boundary will serve as a primary focus for thunderstorm development through the period. By mid day, the front will have surged into northwest OH-central IN and modest boundary layer heating is expected across the warm sector downstream. Current thinking is modest destabilization will be noted across much of the OH/TN Valley such that MLCAPE values should be on the order of 1500 J/kg within a strongly sheared environment. Forecast soundings support this and supercells are expected to develop, in addition to possible line segments and clusters. Large hail is possible with supercells, along with damaging winds and a risk for a few tornadoes. This activity will spread east toward the Middle Atlantic by late afternoon.

Euro has nothing. Cmc also has nothing . I do like that the PNA is rising along with the MJO moving along. Maybe we have a chance

5% tor also shifted ESE

SPC new Day 1 still holds for now... adds 15 hail and moves 30 wind east

tth.

Pretty cool. Sorry you no longer hold the record (I know this one isn’t confirmed yet), but let’s hope this one doesn’t get beat. Good grief I can’t imagine the noise and damage 6in hail would do. Feel bad for any people or animals that had to endure that.

Yes, the current record is Minooka, IL on June 10, 2015 at 4.75". I actually happened to be the warning operator that day and took part in the committee with LOT, NCEI, MRCC, and the IL state climatologist to confirm the record. Sent from my SM-S936U using Tapatalk

Wouldn’t this be the largest hailstone ever recorded in Illinois by over an inch?? Correct me if I’m wrong.

Never any mention of all the under measured amounts though. Central Park 19.7, nope.

I refuse to believe this even with multiple runs being somewhat consistent…..

Snow threat will firmly lift north by the noon runs tomorrow. GFS fighting reality.

Stevens Pass is going to get 2 to 4 FEET of fresh snow! https://www.stevenspass.com/the-mountain/mountain-conditions/mountain-cams.aspx

would be a rude awakening for those that thought winter weather was over for this season.....has happened many times in the past after a March warm up - as late as April...

Copious small hail (covering the ground up to 1”) and major flash flooding in downtown Grand Rapids. This elevated supercell also produced the biggest gravity wave signature I have ever seen on radar. Too bad it was dark.

Rotation starting in the line in Calhoun and St Joseph County MI

GFS on that serious crack rock.

Gfs brings back the coastal for next week. Need it stronger.

We'll see how the rest of Mar and Apr goes but it can't be lower than A- currently for many a reason. There's really no other winter i can think of overall better than this except for 95-96 and 10-11. Another 1-2 Mar/Apr adv or warning events and ill bump it up. Also no major busts, which is rare for any winter season. Most of our good or great ones had a couple. It's a lot like 2000-2001 with better snow pack. Strictly snowfall amounts yeah, but 04-05 was seriously back loaded. Probably 50-60% of our snow occurred from late feb to late mar that season. Each one melted right after it happened. And the "blizzard" sucked balls for most of CT..hours of light to mod snow that slowly piled up with no blizzard conditions. 02-03 was great but had many many teases and near busts like Dec 2002 christmas blizzard, Jan 2003. Also couldn't touch this season with snow pack. And we ended the season on a major Apr 7th bust. 02-03 was like 95-96 lite with wall to wall snow from Nov to Apr. Both those seasons were good-great but had plenty of problems, i think this winter is better overall, just my opinion.

Gotta love it.

Getting some good winds out of the squall line now.
