Isolated marginally severe storms may occur across parts of the

across WI and the U.P. of MI, no appreciable changes have been made
to the ongoing forecast.

.PREV DISCUSSION... /ISSUED 1135 AM CDT Fri Sep 09 2022/
...Southeast States including Florida/eastern GA/coastal SC...
To the east of a persistent upper low centered over the
north-central Gulf of Mexico and middle portion of the Gulf Coast
region, scattered showers and thunderstorms are prevalent over the
eastern Gulf of Mexico toward the western Florida Peninsula and
other parts of the coastal Southeast. Ample insolation is occurring
across the Florida Peninsula to the south of a front coincident with
a very moist environment, although weak mid-level lapse rates will
tend to temper updraft intensities.
Moderately strong southwesterly low/mid-tropospheric winds will
overlie the front from far northern Florida into southeast
Georgia/coastal South Carolina. A few transient supercells could
regionally occur, particularly in proximity to this front. A few
instances of wind damage are possible aside from the potential for a
brief tornado.
...Northern Wisconsin/Upper Michigan...
Will maintain low severe probabilities across the region in vicinity
of the southeastward-moving front. Thunderstorms may persist on an
isolated basis today, with renewed development a bit more probable
toward/after sunset. An instance or two of severe hail could occur.
...Southern California/southwest Arizona...
It still appears that severe potential will remain low north of the
international border in association with current Tropical Storm Kay.
