I am growing a bit concerned about tomorrow & severe risk.
One, it appears that a small cluster of storms or a supercell t'storm will develop in northeastern Illinois & then ride a geopotential height gradient along the warm front right into part of our area.
With good dynamics, high shear & unstable environment, all severe threat (other than flooding) are on the table with this cluster or supercell storm.
The EXACT TRACK is in question, but where it does track, it could pose a wind, tornado & large hail risk.
Overnight Thursday to early Friday morning features cluster of storms moving in & then collapsing over the area.
MARGINAL to SLIGHT RISK is up.
Cooler north, very warm south Friday..............dynamics do not look as great Friday, but still enough for a few storms in the north.
MARGINAL RISK is up for the north & northeast Friday near warm front, outflow boundary & lake breeze front boundaries.
Saturday is dry, windy, very warm & humid with highs 83-88 after morning lows 62-70 & then lows Saturday night 65-70.
Severe risk is up Sunday p.m. still with highs in the 80s.
Monday looks dry with highs 70s to lower 80s.
Wave of storms with severe weather is possible Tuesday afternoon-evening with highs near 80 to the 80s.
