...New AVIATION...

.SHORT TERM...
(Today through Monday Night)
Issued at 212 AM CDT Sun Apr 6 2025

Gusty NW winds and lingering showers with isolated storms continue
over the I-10 corridor and extending down towards the coast. The
Cold front is now well offshore, but lingering elevated moisture
overlapping with PVA from an upper level trough currently located
over the Texas panhandle allows for rain/storm chances to persist
going into the late morning hours. The passage of the 850mb front
scoots out the lingering moisture and brings an end to the rain
chances for quite awhile! You might need a light jacket in addition
to an umbrella as you head out the door this morning as temperatures
will be starting out in the 40s/50s. With lingering cloud cover
north of I-10 and CAA prevailing, we won`t see too much in the way
of warming this afternoon as high temperatures are only expected to
reach the upper 50s to low 60s.

Surface high pressure moves in later today bringing in much drier
air (PW values near or below the 10th percentile). Northwesterly
winds will remain a bit elevated going into tonight as a 25-30 kt
LLJ remains overhead. Low temperatures tonight will still bottom out
in the upper 30s to low/mid 40s...but those upper 30s are a product
of skies clearing out allowing for more efficient radiational
cooling. With surface high pressure overhead, Monday will be dry and
pleasant with high temperatures in the 60s and low temperatures back
in the 30s/40s. It`s not necessarily important to the forecast, but
a shortwave trough axis will be moving in going into late Monday.
With dry air still in place, this won`t do much other than generate
a few upper level clouds...so we might get a decent sunset photo
opportunity in some areas tomorrow night!

.LONG TERM...
(Tuesday through Saturday)
Issued at 212 AM CDT Sun Apr 6 2025

Ridging aloft will prevail through most of the week, leading to
relatively dry conditions. Southerly flow will resume after Tuesday
as the surface high shifts to our east. As result, a gradual warming
trend is anticipated with highs climbing into the mid 80s by
Saturday. Overnight lows will generally remain in the 50s and low
60s. Despite onshore flow, moisture will remain limited; therefore,
dry weather will prevail through the period.

.AVIATION...
(12Z TAF Issuance)
Issued at 615 AM CDT Sun Apr 6 2025

MVFR ceilings are areawide this morning as lingering scattered
rain showers continue along the coast and east of the I-45
corridor. These showers will gradually decrease in coverage
throughout the morning hours and push completely offshore by the
late morning/early afternoon. The main challenge for today will be
the timing of ceiling improvements. Southern sites will see an
earlier improvement to VFR (before or around 21Z) whereas northern
sites are expected to linger around high-end MVFR/low-end VFR
through the afternoon. VFR conditions will return by the evening
hours. Northwesterly winds will remain gusty throughout the day
with sustained winds around 15-20 kt with gusts up to 20-30
kt...the higher end of both of those ranges will be closer to the
coast. Winds decrease to around 10 kt overnight, but will pick
back up into the 10-15 kt range on Monday.

.MARINE...
Issued at 212 AM CDT Sun Apr 6 2025

Light showers with a few embedded thunderstorms can be expected
through early Sunday as the cold front continues to move east of the
Upper TX coast. The main marine concern is wind and seas. Strong
offshore winds are already impacting the Bays and Gulf waters with
near gale fore conditions at times. Moderate to strong north to
northwest winds will continue today and tonight. Winds/seas will
finally start to weaken/subside by Monday. Small Craft Advisories
remain in effect through Monday morning. Light onshore wind resumes
on Tuesday and will persist through the rest of the week.
