Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK

Valid 060100Z - 061200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST
MINNESOTA AND NORTHEAST IOWA INTO SOUTHERN WISCONSIN AND NORTHERN
ILLINOIS...
...SUMMARY...
Severe thunderstorms will continue into tonight across southeast
Minnesota and northeast Iowa eastward toward the southern Lake
Michigan vicinity. A few strong wind gusts remain possible across
the northern Rockies, and a couple of tornadoes associated with
Tropical Storm Debbie remain possible across southeast Georgia into
coastal South Carolina.
...Northeast and Upper Ohio Valley...
Severe thunderstorm potential has largely waned this evening as the
loss of daytime heating results in boundary layer stabilization. As
such, severe probabilities have been removed.
...Upper Midwest vicinity...
Initial supercell storms over southern MN are currently
transitioning toward a more linear/bowing storm mode an a midlevel
shortwave trough continues to shift east/southeast across the Upper
Midwest this evening. This activity will continue to shift
east/southeast along and to the cool side of a warm front draped
across IA into northern IL. A 25-30 kt southwesterly low-level jet
noted around 850 mb orient orthogonal to the low-level theta-e
gradient will promote scale development into tonight. A short term
tornado risk will persist before a transition toward more of a
damaging gust risk.
...Northern Rockies...
Isolated to widely scattered thunderstorms are ongoing this evening.
Moderate to strong vertical shear will support strong to sporadic
severe storms amid modest instability and steep boundary-layer lapse
rates. A couple of the stronger, longer lived updrafts also could
produce marginal hail.
...Southeast GA and Coastal SC...
A couple of tornadoes remain possible overnight as Tropical Storm
Debbie shifts slowly northward. See MCD 1832 for more details on
this continued risk.
