.DISCUSSION...
Issued at 1203 AM CDT Tue Mar 24 2026

The cold front that stalled just north of the Brazos Valley and
Piney Woods region will gradually lift northward tonight into
early Tuesday. Light variable winds are expected tonight along
with low temperatures mainly in the lower 60s inland and the mid
60s over the Houston metro area and the coasts. Low temperature
and dewpoint spreads are expected overnight and with light winds
in place, areas of patchy to dense fog will likely over portions
of Southeast TX once again. It is recommended to check the traffic
conditions before starting your morning commute.

The day will start off cloudy but skies are expected to become
partly cloudy to sunny in the afternoon. The high temperatures will
warm up a few degrees, ranging in the lower 80s over the Piney Woods
region, the mid to upper 80s over the rest of the inland portions,
and the mid to upper 70s along the coast. South-southeast winds will
be light in the morning, then strengthen to 06-12 mph in the
afternoon. Winds will relax to around 5 mph near midnight.

On Wednesday, a mid-level high over northwestern Mexico will
strengthen and progress east into northern Mexico and western TX.
This will continue to result in a warm and dry weather pattern
over Southeast TX. The high temperatures are expected to range in
the upper 80s to lower 90s through the end of the work week. Under
the influence of southerly winds, moisture from the Gulf will
continue to filter into the region. This will help keep dewpoints
similar to the low temperatures (lower to mid 60s), leading to
periods of patchy to locally dense fog during the overnight and
early morning period for the rest of the week.

The weather for the upcoming weekend still looks to be a bit cooler
once a dry cold front pushes through Southeast TX sometime late
Friday or early Saturday. Although there are still some model
discrepancies with the timing of the front, they have been
consistent on indicating cooler temperatures during the weekend.
We might be lucky enough to have highs range in the mid 70s to
lower 80s range on Saturday. Unfortunately, southerly flow returns
quickly by early next week, leading to a warming trend once
again.

VFR through early tonight. SE winds at 06-12 KTS through this
evening, becoming light and VRB tonight into early Tue morning.
IFR-MVFR cloud decks are expected to develop overnight, along
with reduced vis due to areas of patchy to dense fog. There`s a
chance for vis to decrease to less than 1SM and cigs lowering to
VLIFR-LIFR over isolated portions of SE Texas from around 09-14Z
Tue. We will see a gradual improvement in both vis and cigs after
14-15Z for most locations. Cloud decks will continue to lift and
scatter out during the late morning to early afternoon hours and
S-SE winds will strengthen to 06-12 KTS.

.MARINE...
Issued at 1203 AM CDT Tue Mar 24 2026

Light southeasterly winds and seas of 1-3 feet are expected for
the rest of the work week. Areas of patchy sea fog is possible
over the bays and adjacent nearshore waters during the next few
days generally between the evening to mid-morning hours. A dry
cold front could push through Southeast TX sometime late Friday or
early Saturday, resulting in moderate to strong east northeast
winds and elevated seas in the wake of the front. Caution Flags
and Small Craft Advisories may be needed Friday night into
Saturday. Conditions should improve on Sunday.
