.SHORT TERM...
(Today through Thursday night)
Issued at 319 AM CDT Tue Apr 30 2024

Main concern this morning is widespread dense fog forming across
the region. Satellite imagery continues to show the expansion of
fog and this will continue until sunrise. Expect improvement
after sunrise with the dense fog adv expiring at 10 am.

The rest of the day will see highs in the middle 80s with the
majority of the area dry. There could be some isolated
showers/storms in SETX, but confidence is low at this time.

Wed/Thu confidence increases for showers/storms as multiple
disturbances move across the region. Plenty of moisture and
instability will be availble for storms. While severe weather is
not expected at this time, some of the stronger storms could
bring heavy rain. Therefore the WPC, placed portions of the area
in a marginal/slight risk for heavy rainfall.

.LONG TERM...
(Friday through Tuesday)
Issued at 319 AM CDT Tue Apr 30 2024

Frontal bndry stalls across the region late week into the weekend,
before finally washing out. This will result in daily
showers/storms each afternoon into the weekend. It is possible,
by early next week, mid-level ridging and a more progressive
pattern may finally result in a reduction of POPs/drier weather.

Daytime highs cool a little on Friday with highs in the lower 80s,
but warm right back up by the weekend intop the middle/upper 80s.
By early next week, ridging could push some interior locations in
TX/LA into the lower 90s.

.AVIATION...
(06Z TAFS)
Issued at 319 AM CDT Tue Apr 30 2024

Little change from previous TAF thinking with clear skies and
light winds now noted areawide. Patchy fog is already seen in area
obs although terminal sites remain VFR attm. Still expect areas
of BR/FG and possibly some low clouds to develop overnight. Vsby
reductions to MVFR are anticipated over the next 2-3 hours, with
occasional LIFR vsbys/cigs possible late tonight, mainly at the LA
terminals. Conditions should improve to VFR by 15Z at the LA
airports with cigs lifting/scattering by 17Z at BPT. VFR/light
southerly winds expected to prevail thereafter.

.MARINE...
Issued at 319 AM CDT Tue Apr 30 2024

Chances of showers and thunderstorms will increase through
the middle of the week as the surface trough and deep layer upper
level trough approaches the area. Onshore flow expected for the
the period with an SCA possibly needed by Thursday as the pressure
gradient tightens slightly more with winds in the gulf waters
increasing above 20kts briefly.
