KEY MESSAGES

- Rain-free conditions and well above normal temperatures are expected through next weekend.

- Low relative humidity is forecast Sunday afternoon, however wind speeds look to remain light enough to limit fire weather concerns.

DISCUSSION

Issued at 1145 AM CST Sun Feb 15 2026

Another warm afternoon is expected across Deep South Texas with highs mostly in the 80s, despite the passage of a cold front earlier this weekend. Northerly winds generally around 10-15 MPH with occasional gusts up to 20 MPH will continue through the afternoon before falling below 10 MPH this evening. Low level southerly to southeasterly flow will return by tomorrow afternoon and evening and persist through much of the week. Occasionally gusty afternoons, particularly along the immediate coast and Gulf waters, cannot be ruled out due to a locally enhanced pressure gradient.

Otherwise, well above normal temperatures and rain-free conditions are expected through at least next weekend as the region remains under the influence of mid/upper level ridging. High temperatures will likely approach the low to mid 90s by Tuesday, and a few areas west of US-281 may approach the mid to upper 90s by Thursday. For McAllen Airport, this is around 15-20 degrees above normal for mid February, and the record high temperature on Thursday, February 19th is 97 degrees (set in 1986). The current forecast high temperature for the 19th at McAllen is 96 degrees.

AVIATION

(18Z TAFS) Issued at 1145 AM CST Sun Feb 15 2026

VFR will prevail through the forecast period at all TAF sites. However, there remains a low potential (30% or less) brief MVFR visibility as patchy fog develops once again late tonight into early tomorrow morning.

MARINE

Issued at 1145 AM CST Sun Feb 15 2026

General favorable marine conditions will prevail along the Gulf waters and Laguna Madre throughout the week, although brief periods of Small Craft Exercise Caution conditions cannot be ruled out during the afternoon hours as the pressure gradient tightens. Rain-free conditions are expected through next weekend.
