.SHORT TERM...
(Saturday through Sunday)
Issued at 335 AM CDT Sat Apr 20 2024

Very diffuse frontal boundary has cleared our southernmost zones 
this morning with spotty post-frontal showers starting to expand
across parts of East Texas and North Louisiana. This trend will
continue to ramp up over the next 24 hours in terms of convective
coverage and intensity as a series of upstream shortwave impulses
translate eastward across Texas into the Lower MS Valley. Although
convection will gradually overspread the entire region later today
and tonight, pockets of heavy rainfall and embedded thunderstorms
are expected to become more focused along and south of the I-30 
corridor where 1-2 inches of rainfall will be common along with 
localized higher amounts near 3+ inches. 

The bulk of this rainfall should occur from this afternoon through
early Sunday morning before the primary trough axis finally pivots
overhead and gradually brings an end to the rainfall. Cloud cover
will eventually follow suit by Sunday afternoon with at least some 
sunshine returning late in the day. As a result, afternoon warming
will allow high temperatures to climb into the 60s areawide versus
slightly milder rain-cooled air across the majority of the region
today. The exception will be across our far southern zones closer
to the frontal boundary where cool air advection hasn't been quite
as pronounced given how diffuse the front has become. Regardless,
we will maintain below average temperatures areawide with morning
lows bottoming out in the 40s near 50 degrees across the region.

Hazardous Weather Outlook For UNION County, LA

626 AM CDT Sat Apr 20 2024

 DAY ONE  Today and tonight.

An upper-level disturbance shifting across the region today through
tonight will be the catalyst for widespread showers and thunderstorms
with periods of heavy rainfall. Look for 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. Poor
drainage and flood prone areas will also be susceptible to localized
flash flooding.

 DAYS TWO THROUGH SEVEN  Sunday through Friday.

An upper-level disturbance will continue to shift east of the region
on Sunday with some lingering rain showers in the morning gradually 
ending by the afternoon. Dry conditions will resume for much of next
week with the next chance of thunderstorms possibly returning by the
end of the week. However, any threat of severe weather is uncertain
at this time but will be closely monitored over the coming week.

 SPOTTER INFORMATION STATEMENT  

Spotter activation is not expected at this time.
