...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF

THE MIDWEST...



...SUMMARY...

Marginally severe hail remains possible tonight from eastern Iowa

into northern Illinois.



...01z Update...



Earlier thoughts regarding the prospect for a few robust storms

across the Midwest remain. Moisture is gradually advancing north

across the mid MS Valley per 50F surface dew points now north of I70

in MO. While 00z sounding from DVN exhibited very steep midlevel

lapse rates, only 0.67 inch PW was observed on the sounding.

Instability should increase over the next several hours such that

elevated thunderstorms are expected to increase in areal coverage,

initially over eastern IA. Latest radar/lightning data suggests

isolated thunderstorms have recently developed over southeast IA and

this activity will spread east within the warm advection zone into

northern IL. Strongest updrafts may generate hail that could

approach severe levels, most likely later this evening as buoyancy

increases. Even so, these robust storms will remain isolated.
