Areas affected...Southeast Wisconsin and Northern Illinois

Concerning...Severe potential...Watch unlikely

Valid 232328Z - 240100Z

Probability of Watch Issuance...5 percent

SUMMARY...Thunderstorms will continue this evening. isolated large
hail will be the primary threat.

DISCUSSION...Elevated thunderstorms are developing across the upper
Midwest on the nose of the 850-millibar moist, warm-air advection.
These thunderstorms are on the eastern edge of the steeper mid-level
lapse rates (between 7-8 C/km) and will continue to move generally
eastward toward a more stable environment over/near Lake Michigan.
Until then, over the next 1-2 hours, isolated large hail will be
possible with the strongest thunderstorm cores. Given the limited
spatio-temporal nature of the remaining threat, a watch is currently
not anticipated.
