...New SHORT TERM, LONG TERM...

.SHORT TERM...
(This evening through Wednesday Night)
Issued at 114 PM CDT Tue Apr 16 2024

Upper trough across Southern/Central Plains will continue slowly lifting
out to the north and east overnight tonight. Across our region and
upstream, WSW flow aloft continues to dominate the Southern Plains
with weak upper level forcing noted across the Middle Red River
Valley of NE TX, SE OK and SW AR. Cold front in association with
this trough will move into NE OK and NC TX before stalling late
tonight and this frontal boundary is not forecast to even make it
into McCurtain County before pulling up stationary late tonight.
Instead, 850mb theta-e ridging across NE TX into far SE OK and SW
AR in advance of the sfc cold front will likely be the feature
that storms could develop on later this afternoon/evening with the
850mb cold front pushing south and east into N LA towards sunrise
Wed Morning. Given the lack of more significant upper forcing, did
back off likely NBM pops for tonight, characterizing them as more
scattered in nature vs likely storm coverage across our northwest
half. Low-end moderate instability will best describe the warm 
sector in advance of the true cold front this evening with descent
lapse rates, suggesting that small hail cannot be ruled out of 
any strong storms that form this evening but more organized severe
convection will likely remain north of our area through the 
night. 

The cold front will remain north of our region on Wed with this 
feature returning back to the north as a warm front. Meanwhile, 
we will have virtually no upper level ascent noted aloft and the 
850mb boundary will have washed out across our region. All this to
say, pops look negligible for Wed thru Wed Night attm. Did not 
stray far from NBM temps on Wed or Wed Night given that NBM temps 
are on the warmer side of guidance and this seems plausible given 
cloud cover will be plentiful and continued southerly winds.
