.SHORT TERM...
(This afternoon through Monday Night)
Issued at 1147 AM CDT Sun Apr 13 2025

The sunny, warm and breezy weather continues. Low-level humidity
levels are on the rise today, but high pressure in the mid/upper
atmosphere continues to produce sinking air leading to no rain
chances early this week. A weak frontal boundary will move into
and across SE TX Monday night, bringing in lower dew pts and
therefore lower humidity values for Tuesday.

.LONG TERM...
(Tuesday through next Saturday)
Issued at 221 PM CDT Sun Apr 13 2025

The frontal boundary mentioned in the short term will be across the
coastal waters by early Tuesday. This is a weak front and will only
bring drier conditions with dewpoints gradually falling into the 40s
and 50s degF range, mainly north of I-10. Given that this is a
weak/dry front, dewpoints across the coastal areas are progged to
remain in the 60s.

Surface high pressure builds in across the Plains, shifting eastward
throughout the week. Mid to upper level ridge shifts to the Plains,
resulting in southwesterly flow across SE TX. Therefore, a warming
trend with increasing humidity levels can be expected for the
remainder of the period. Highs will generally be in the upper 80s to
near 90.

Pattern aloft changes as we enter to the upcoming weekend (Easter
weekend) with rain chances returning to the forecast. Rain and
storms chances will be possible ahead of a deepening upper low over
the Four Corners, moving into the southern Plains through the
upcoming weekend. As of now, kept 20 to 35 percent chance of
precipitation Friday - Saturday generally north of I-10...with the
best chances across our northwestern counties (mostly Brazos Valley.

.MARINE...
Issued at 221 PM CDT Sun Apr 13 2025

Surface high pressure centered across the eastern Gulf will continue
to bring onshore winds across the Upper TX coast this week. A weak
cold front moving across the Plains is creating a tight pressure
gradient, resulting in breezy conditions. Therefore, winds from 15
to 20 knots can be expected this evening into late Monday. The front
will attempt to move across the Bays and nearshore waters by early
Tuesday before it washes out. In the wake of the front, dry and warm
weather continues with light to occasionally moderate onshore winds.
Seas will remain in the low side, increasing up to 6 ft (offshore)
towards the weekend.
