...New AVIATION...

.SHORT TERM...
(Friday through Saturday)
Issued at 349 AM CDT Fri Apr 19 2024

A slowly advancing frontal boundary continues to shift SE near the
I-30 corridor early this morning, evident by the wind shift to the
NW and subsequent cool air advection. Ambient temperatures are in
the upper 50s to mid 60s north of the boundary compared to mostly
in the 70s south. As for convection, the only activity remains to
our north near the Little Rock metro area where a shortwave is 
contributing to a few isolated strong to severe storms. With the 
relative lack of forcing across our region today, convection will 
remain hard to come by aside from just some very isolated showers 
and perhaps a stray thunderstorm as the cold front continues its 
slow but steady progression SE throughout the day. The speed of 
the front could be problematic in terms of the high temperature 
forecast for today, resulting in quite a spread from the mid and
upper 60s NW to the lower and mid 80s SE.

By early this evening, the cold front should be very near if not 
clearing our far southern zones just as a series of shortwave
impulses begin to emerge across North Texas into the Middle Red 
River Valley. As the first in this series of shortwave impulses 
transitions through the W/SW flow pattern starting late tonight 
through Saturday, expect showers to gradually become widespread 
with embedded thunderstorms increasingly likely later in the day
on Saturday. Temperatures will be noticeably cooler following 
fropa with little movement expected throughout the day as highs 
only manage the mid and upper 50s north into the lower 60s along 
I-20 and slightly warmer farther south.

Hazardous Weather Outlook For UNION County, LA

630 AM CDT Fri Apr 19 2024

 DAY ONE  Today and tonight.

A cold front will continue to shift across the region today, but any
thunderstorm activity should be isolated. The chance of thunderstorms 
will increase later tonight as an upper-level disturbance approaches
the region from the west, mainly after midnight through the predawn 
hours on Saturday. However, no hazardous weather is expected at this
time.

 DAYS TWO THROUGH SEVEN  Saturday through Thursday.

An upper-level disturbance will continue to produce scattered storms
and more widespread showers with periods of heavy rainfall through 
Saturday night before the storm system moves east of our region on 
Sunday. Look for widespread rainfall amounts of one to three inches
with isolated higher amounts possible. This may result in additional
rises on area waterways through early next week. Low-lying and poor 
drainage areas will also be susceptible to localized flash flooding.

 SPOTTER INFORMATION STATEMENT  

Spotter activation is not expected at this time.
