(Thursday through Friday)
Issued at 322 AM CDT Thu Apr 25 2024
Once again starting off a little warm with upper 60s for the
average, with end points of 62/62 in Ruston with fog and 70
degrees in downtown Shreveport. Skies are mostly fair with patchy
fog beneath, except for SE OK / S AR under clouds riding over
the cooler air associated with that weak backdoor frontal
boundary from yesterday. The SE winds look to prevail until
further notice aside from brief S/SW Monday afternoon behind the
heaviest rain period. We will be talking about sea breeze activity
in May with this pattern of flow inland off the Gulf.
However, the Westerlies will still impose their will this weekend
with the number two and especially number three punches. The
upper ridging extends from TX to Canada west of the MS River and
will drift eastward slowly, building shield power with heights
soaring. Highs today will push more sites into the mid 80s and
some upper 80s over the weekend with our lows in the upper 60s and
lower 70s for a while. Short term rainfall today will focus
slight chance pops over that retreating backdoor front today and
then start to edge our way after midnight tonight into SE OK and
NE TX and lots more of our real estate going forward. /24/

(Friday Night through Thursday)
Issued at 322 AM CDT Thu Apr 25 2024
Overall, not much new to see here with the looming pattern of
occluding lows racing off the front range and over the high
plains, still much of the country dealing with these back to back
tracks to end the month. And we will see rain totals continue to
pile up with a hearty gradient mentioned a couple of days ago, and
right through our neck of the woods. The WPC has really entered
the fold with EROs running over our cwa with some presence from
days 2 through day 5. Certainly we are going to need a flood
watch(es) this go around, but exactly which of our Counties and
potential Parishes is a little distant 12hr forecast period-wise.
Some of the Slight Risk ERO details will likely upgrade to
Moderate this weekend with the day 4 our most likely candidate.
The best news is, our rivers and lakes are lowest where rain will
initially begin to pile up this weekend. Other ArkLaTex affected
sites last go around are all falling and will only have more room
to store runoff before early next week. So we will watch daily how
the subtle lines are drawn over much of the plains and midSouth
U.S. this weekend with convective watches. The SPC outlooks days
1-3 are all sporting an Enhanced Risk area with our turn also
holding off until day 4ish. So stay tuned this weekend and
remember that the latest information could save lives. Please keep
abreast of this Spring Storm multi- day event, if plans are
riding it all out here at home, but especially if this weekend
includes a tank of gas travel around our 4 state (plus) region.

(18Z TAFS)
Issued at 108 PM CDT Thu Apr 25 2024
For the 25/18z TAFS...A mix bag of flight conditions across the
region at this hour, with reduced flight categories at all of the
East Texas sites. Should see some improvement to VFR by late
afternoon at all sites, but the reduced categories will return
back to all sites by the end of the period, along with some
possible showers/t-storms at all sites except KELD/KMLU.
