Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0218 AM CDT Sun Sep 29 2024

Valid 011200Z - 021200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Tuesday.

...Synopsis...
A weak mid-level shortwave trough will move offshore in the
Mid-Atlantic on Tuesday. Isolated thunderstorms may occur in far
eastern North Carolina during the afternoon before the trough
departs. A more substantial upper-level trough will move through the
upper Great Lakes region by early/mid afternoon. This trough will
push a surface cold front through much of the Midwest and Ohio
Valley regions. Dewpoints ahead of the cold front are forecast to be
in the low 60s F. Lingering effects of ridging aloft are evident in
forecast soundings. However, where mid-level ascent is greatest,
some thunderstorm activity is possible along the front in eastern
Lower Michigan into parts of northern/central Ohio. Some gusty winds
could occur with this activity, but weak low-level winds and the
mentioned thermodynamic weaknesses should preclude severe weather
potential. The highest coverage of thunderstorms is most likely
within the Florida Peninsula as the moist airmass heats during the
day and sea breeze boundaries provide lift.
