.SHORT TERM...
(Tonight through Sunday night)
Issued at 330 PM CDT Fri May 3 2024

Area radar this afternoon shows scattered showers and
thunderstorms spreading across the region from the west. Most of
today`s precip has fallen across SE TX and SW LA, with area
mesonet stations showing around 0.75-2.00" of rain has fallen
in these regions. CAMs have largely handled today`s system poorly
however, the HRRR seems to have gotten a better handle on it over
the last couple of runs and continues to show most of this
activity ending between 6 and 8 PM this evening. Overnight, dry
weather is expected along with another round of patchy fog,
especially across those areas that saw a good bit of rain today.

Moving into the weekend, rain chances continue. Tomorrow, another
shortwave is expected to pass overhead and initialize scattered
showers by the late morning hours. POPs tomorrow are only in the
20-40% range, with better chances north of I-10, and overall
coverage should be much less than the last couple of days. Rain
chances then ramp up again for the second half of the weekend as a
second, more robust, shortwave slides overhead and passes a bit
further to the south that Saturday`s shortwave. This may bring a
similar set up to today`s convection, with elevated rain chances
in the 40-60% range on tap area-wide. Fortunately, no severe
weather is anticipated this weekend however, we will have to keep
an eye on the flooding risk as much of the forecast area has
already received significant rainfall over the last couple of
days.

Temperature wise, we will see near seasonal daytime highs over the
weekend, warming into the low to mid 80s area-wide both days.
Overnight, lows will continue to fall into the upper 60s inland
and low to mid 70s along and south of I-10.

.LONG TERM...
(Monday through next Thursday)
Issued at 330 PM CDT Fri May 3 2024

As we head into the work week small rain chances continue for
Monday followed by a reprieve from the wet weather through the
mid-week. POPs on Monday are only around 15-30% at best, with
mainly isolated afternoon activity anticipated. Tuesday through
Thursday a drier pattern is expected as a weak midlevel ridge
builds over the Gulf Coast and offers a bit of drier air aloft to
keep showers at bay. Finally by Friday we may see a return of
shower activity as some long range models are now pointing to a
weak frontal passage. This is still a ways out however, and
changes to the progression of this front are likely.

Temperature wise next week will bring a gradual warming trend
with highs on Mon in the mid 80s warming into the mid to upper 80s
on Tuesday and into the upper 80s to lower 90s from Wednesday and
beyond. Overnight, lows in the low to mid 70s can be expected.

.AVIATION...
(00Z TAFS)
Issued at 616 PM CDT Fri May 3 2024

A few showers or storms will be possible until sunset mainly for
terminals along the I-10 corridor. Otherwise, starting out with
VFR conditions.

Once again expecting low clouds and patchy fog to form around
04/06z and persist into the overnight with mainly MVFR conditions,
although some brief IFR conditions can be ruled out.

Patchy fog and low clouds will lift during the morning hours, with
VFR conditions expected by 04/18z. Shower and storm activity looks
to be a lot less for Saturday, and therefore, will just mention
VCSH and VCTS for terminals.

Scattered showers and thunderstorms will continue into this

sunrise especially along and near the coastline. Light onshore
flow and low seas will prevail through the rest of the upcoming
