KEY MESSAGES

Updated at 1234 PM CDT Mon Jun 22 2026 - Hot and rain-free conditions are expected through the period with the heat risk being mostly moderate (level 2 of 4) each day.

- Small Craft Advisory remains in effect through 1 AM Tuesday due to elevated southeasterly winds.

DISCUSSION

Issued at 1234 PM CDT Mon Jun 22 2026

A trend of hot and rain-free conditions are expected to persist through the period. This is due to a mid-level ridge over the region resulting in high temperatures in the range of mid to upper 90s. However it is possible for some areas to see triple digits as well. The heat risk for today is most moderate (level 2 of 4), but there are some places that could be in a major (level 3 of 4). As for the rest of the week, the heat risk is expected to be mostly moderate. The heat indices for each day are expected to be close to 108, which is below criteria for Heat Advisory, but could merit an SPS for elevated heat indices. Breezy conditions are expected for the rest of the afternoon and early evening hours today and tomorrow. However, there should be a bit of a lull in the winds come Wednesday through the start of the weekend.

Conditions for the Lower Texas Coast should generally be pleasant, though a moderate risk of rip currents is expected to persist for the next couple of days.

AVIATION

(18Z TAFS) Issued at 1234 PM CDT Mon Jun 22 2026

VFR conditions are expected to continue with gusty southeasterly winds around 25 to 30 knots for the rest of the afternoon into the evening at all TAF sites. While the southeasterly winds should weaken for the overnight hours, VFR conditions should remain in place as well. By mid-morning, the southeasterly winds will become gusty again to around 25-30 knots again.

MARINE

Issued at 1234 PM CDT Mon Jun 22 2026

The Small Craft Advisory has been extended to late tonight as frequent wind gusts over 20 knots are currently being observed still and will persist for a while longer. While the winds will decrease starting late tomorrow, Small Craft Exercise Caution conditions remain possible each day during the afternoons as winds increase during that time. There is a good chance that Small Craft Advisory conditions return for the weekend as the winds increase yet again.
