Valid 181200z - 191200z
..no severe thunderstorm areas forecast...
thunderstorms will be possible from the Texas coastal plain and
south Texas, east across the Gulf Coast states and southeast on
Saturday. No severe threat is expected.
A positively tilted short-wave trough is progged to move rapidly
across the Midwest through early portions of Saturday, but will
quickly deamplify with time as it shifts into the northeast/New
England. In the wake of this feature, the pattern will revert to a
longer-wavelength and lower-amplitude western ridge/eastern trough
At the surface, a deep low will move across the Great Lakes region,
as a trailing cold front shifts out of Missouri/Arkansas/Texas and
across that portion of the U.S. East of the Mississippi River. By
the end of the period, the front should extend from southern New
England and the mid Atlantic coastal vicinity, southwestward across
the East Coast states and into the northeast and central Gulf of
Ahead of this front, showers and a few thunderstorms are expected,
though very weak instability in the warm sector will preclude severe
storm development. Elsewhere, cold/polar high pressure will prevail
-- hindering prospects for deep moist convection over the remainder
of the U.S. West of the eastern cold front.
