...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast through tonight.

...Synopsis and Discussion...
A shortwave trough, and accompanying intense jet streak with 500 mb
winds over 100 kt, will continue eastward through the OH Valley
today and off the Northeast coast by early tomorrow. Surface low
associated with this wave will progress northeastward from its
current position over southeastern Lower MI/southwestern Ontario
along the St. Lawrence Valley today, continuing through ME and into
the Canadian Maritimes by early tomorrow. An extensive cold front
extending southeastward from this low will push quickly
eastward/southeastward through the southern Plains and much of the
eastern CONUS, ending the period well off the East Coast.

Passage of this cold front will reinforce the dry and stable
conditions across the majority of the CONUS, precluding
thunderstorms. Modest low-level moisture will remain over
central/southern FL throughout the day, but warm low to mid-level
temperatures will prohibit deep convection, limiting the
thunderstorm potential.
