Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0158 PM CST Tue Dec 10 2019
Valid 102000Z - 111200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Thunderstorms will remain possible today across parts of the
southeast United States. No severe storms are expected.
A cold front continues to move southward over the northern Gulf of
Mexico and the Southeast this afternoon. Thunderstorm potential
through the remainder of today and tonight will likely be confined
to locations near/ahead of the front, as weak instability becomes
increasingly negligible behind it. The general thunderstorm area
across the Southeast has been adjusted to account for these trends.
.PREV DISCUSSION... /ISSUED 1016 AM CST Tue Dec 10 2019/
An upper trough is moving eastward across TX today, with a strong
midlevel jet extending from east TX across the Gulf Coast states. A
combination of large-scale forcing for ascent, marginal elevated
CAPE values, and ample midlevel moisture will continue to pose a
risk of widespread showers today and tonight - mainly along and
behind a surface cold front sagging across the southeast states.
Coverage of thunderstorms will likely be limited, but a few
lightning strikes are possible across a relatively broad area.
