..no severe thunderstorm areas forecast...
low chances for isolated thunderstorms are forecast over a portion
of the Southern Plains northeastward into the middle Mississippi
River valley. Other isolated thunderstorms may occur over southern
Florida...the Pacific northwest and a small part of southern New
England. No severe weather is expected.
Closed upper low over the eastern U.S. Is forecast to move slowly northeastward
along the middle Atlantic Seaboard into southern New England Thursday.
Farther west an upper trough will continue from the plains through
the MS valley and reach the Great Lakes...Ohio and Tennessee valleys Thursday
night. A broad upper trough will persist from over the Pacific northwest
into the northern rockies. High pressure will build over the southwestern states.
..ern OK and eastern Kansas into the middle MS valley region...
A few elevated showers and isolated thunderstorms may be ongoing
from eastern portions of southern and Central Plains into the middle-MS valley
region within zone of weak ascent east of upper trough axis. The
tendency will be for this zone of modest ascent to shift east of
weak instability axis...suggesting trend should be for morning
convection to undergo a gradual decrease.
Steep middle-level lapse rates associated with cold air aloft within
the broad cyclonic flow regime will contribute to weak instability.
Zones of deeper ascent accompanying embedded vorticity maxima will
further promote development of scattered convection...some of which
may become capable of producing lightning.
A few thunderstorms will remain possible over deep S Florida in vicinity
of stalled front.
..srn New England...
Scattered convection including a few thunderstorms developing mainly
offshore in association with upper low circulation will affect
portions of southern New England.
