Day 4-8 Convective Outlook 
NWS Storm Prediction Center Norman OK
0339 AM CST Mon Nov 18 2024

Valid 211200Z - 261200Z

...DISCUSSION...
A mid-level trough is forecast to move into the western Atlantic
Thursday night, as a mid-level ridge builds over the western U.S.
The ridge is forecast to gradually move eastward across the U.S.
from this weekend into early next week. A relatively dry airmass is
forecast over most of the continental United States through
Saturday, suggesting that thunderstorms will be unlikely. Low-level
moisture is forecast to advect northward into the Ark-La-Tex on
Sunday and into the mid Mississippi Valley on Monday. Within this
moist airmass, isolated storms will be possible. However,
instability is forecast to be limited suggesting a severe threat
will be minimal.
