Day 1 Severe Weather Outlook

Valid 150100Z – 151200Z


Severe thunderstorms are not expected across the contiguous U.S.
through tonight.

Water-vapor imagery this evening shows a shortwave trough moving
from MT into the Upper Midwest. A surface low will develop eastward
towards the MS River late tonight. Isolated showers and a few
thunderstorms are possible a few hours prior to daybreak over the
mid to upper MS Valley. Farther south, a plume of mid- and
high-level moisture will remain from northern Mexico eastward along
the central Gulf Coast. Showers and a few thunderstorms are
possible from east TX into the northeast Gulf Coast. Widely spaced
thunderstorms are possible over parts of southwest TX this evening
and moving into central TX by early morning. Weak instability will
preclude strong thunderstorm development tonight.
