...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
THE UPPER MIDWEST...

...SUMMARY...
Areas of severe storms are possible across the Upper Midwest on
Thursday.

...IA/MN/WI...
A large non-severe MCS is tracking eastward this morning across much
of southern WI and northern IL.  In the wake of this system, visible
satellite imagery shows broken clouds and the potential for areas of
heating later today.  Ample low-level moisture remains across parts
of IA/MN where large MLCAPE values (over 4000 J/kg) are forecast to
develop.  Upper-level forcing mechanisms are hard to identify.
However, continued subtle low-level warm advection coupled with
daytime heating are expected to initiate isolated thunderstorms over
parts of northern IA and southern MN by late afternoon.  Forecast
soundings show steep midlevel lapse rates and sufficient deep layer
shear for supercell storm structures capable of large hail and
damaging winds.  Activity that forms will track eastward across WI
during the evening with a continued severe threat.

...Eastern MD to southeast NY...
Considerable sunshine is expected today along a corridor from
eastern MD into NJ, eastern PA, and southeast NY.  This area will be
on the southern fringe of the stronger westerlies, with forecast
soundings showing steep low-level lapse rates and just enough
westerly winds in the 1-3km range to pose a risk of gusty winds in
the strongest cells.
