Indystorm

0-3km helicity up to 200 to 300 m2/s2 in that part of WI Interesting that mid level lapse rates were not all that good today.

Increasing svr risk for central and northern IN as cells approach from the sw. Helicity not all that high yet but will slowly increase thru the afternoon and evening. High tor parameters are focused for the southern parts but we all know what happened north of Tulsa yesterday.

Two tor warnings around the Rockford area at present....2:15 central

SPC meso says 95% prob of a tor watch coming for the Ohio Valley in the next hour or so....

Radar confirmed tor near Batavia moving ne

Low level helicity is stronger down by the Ohio river than up in northern IL, but we shall see what happens.

Satellite looking interesting sw and se of the Quad cities. Expect formation soon if cap allows

Probably because moisture is not all that high in the sixties but the contras is great for this time of year

17 point dew point spread between Davenport IA and Princeton IL 41 to 58

Tor watch coming for ne IL and nw IN per SPC meso

Didn't think I'd be signing in for svr season this early in the Calumet region, but parameters for later tonight are quite concerning.

Cicero has really taken it on the chin with that storm July 2 that produced massive flooding and now many areas will be facing this situation overnight tonight.

I don't like the looks of that destructive 80 mph line of storms at the Quad Cities area now moving east at 70.

I don't think the hatching was there earlier.

If this congeals we might have the beginnings of a derecho overnight as it moves from eastern IA and sw WI to the southeast.

95% chance svr watch to be issued for northern IL and nw IN with a svr storm over Naperville at present

Is the lake breeze gonna give us an appetizer here in the Calumet before the entree later this evening?

Had an amazing electrical storm at 5 a.m. today and there were a lot of limbs and branches down on the east side of Griffith especially. This includes a large 1 to 2 foot diameter tree trunk near the Wadsworth Elementary school just south of me. Waiting to see what will happen with this power keg tonight. 700mb still around 12 per SPC meso so gotta cool a bit first.

My understatement of the year is that I really did not expect confirmed tornadoes in the Chicago metro today.
