.DISCUSSION...
Issued at 153 PM CDT Wed Mar 18 2026

Dry and hot conditions, with the potential for near-record or record
breaking temperatures at some locations are the main weather story
over the next several days. Surface high pressure centered to our
east continues to dominate the weather across the region today with
dry and warm southerly winds. Aloft, the region continues to be
influenced by a strong high pressure ridge (594 dam) centered over
the southwestern CONUS, bringing unseasonably high temperatures for
mid/late March. Heat will intensify over the next 72 hours as this
ridge slightly amplifies and expands eastward into the region from
Friday into the weekend. Ensemble guidance continues to show 850
temperatures close to the 90th - 99.5th percentile of climatology
(according to NAEFS and GEFS), especially west of I-45. Based on the
NBM probabilistic data for temperatures, the Brazos Valley area
(CLL) will have the highest probability (around 70 to 85 percent)of
temperatures greater than 90F on Saturday.

By early next week, the ridging aloft breaks down a bit as a weak
and generally dry surface cold front attempts to move southward
through the region. No significant impacts are expected, other than
temperatures becoming a couple of degrees "less warm" with highs
mainly in the mid 80s.

.MARINE...
Issued at 153 PM CDT Wed Mar 18 2026

With the high pressure centered over north-central Gulf, the region
continues to be influenced by light to occasionally moderate
southeasterly flow and seas of around 1 to 3 ft. This pattern will
persist through the weekend. Little to no rain is expected.
