Issued at 220 PM CDT Thu Apr 18 2024

Tonight and Tomorrow: The severe weather and flooding threat in 
the northern portions of the CWA will be the main focus for the 
short term forecast as a slight and marginal risk areas for severe
will continue through midnight tonight. Damaging wind gusts up to
60mph, hail up to golf ball sized, severe storms possible will be
the main threats for this event as well as a tornado not being 
able to be be ruled out. Flash flooding will also be possible near
the ArkLaMs borders due to the repetitive nature of the 
forecasted storms heavy rainfall over the same area. While we 
still expect this to be scattered thunderstorm event, if storms do
form there is the possibility for supercell development which 
could produce hail up to golf ball sized, damaging wind gusts and 
a tornado cant be ruled out. The timing of the main brunt of this 
weather will last until around midnight tonight. As storms wrap up
expect isolated shower and storm chances to remain through the 
overnight but will remain mostly above I-20 with best chances 
above Hwy-82. Going into the morning dense patchy fog will be 
possible again in the southeastern portions of the CWA as excess 
moisture and light winds will make development easy and more 
likely due to persistence. Going into the early morning a cold 
front will be in the process of dropping into the CWA allowing 
rain chances in the north to persist through the afternoon as the 
boundary moves off to our east. Rain chances will continue in the 
northeastern portions of the CWA through the forecast period./KP/

Saturday through Thursday: The pattern change will continue 
through the weekend and into early next week as an upper-level 
ridge over the Gulf of Mexico refocuses over the southwestern U.S.
and upper-level troughing becomes more prevalent over the eastern
U.S. Building surface high pressure will make its way southeast 
out of the High Plains and toward the Mid- South behind a cold 
front Sunday into Monday. It should bring drier air and initially 
cooler weather to the Gulf Coast region. Flow aloft over our area 
will be mostly zonal in the early to midweek time frame, and it's 
possible a shortwave moving north of our area and its attendant 
cold front could trigger a few showers or thunderstorms as the 
system glances by our region. For now, POPs are an uncertain 20 
percent for next Wednesday. Temps will warm to above normal again 
as the high pressure shifts eastward. /NF/
