KEY MESSAGES

Updated at 456 AM CST Mon Jan 19 2026

- Warming trend through late week - Increasing rain chances midweek will peak Wednesday as deeper moisture arrives - Freezing temperatures look to return this upcoming weekend as a strong cold front brings colder air with low-to-moderate rain chances

DISCUSSION

Issued at 1113 PM CST Sun Jan 18 2026

This week will be characterized by a gradual warming trend, briefly interrupted by a midweek disturbance, followed by a strong cold front this weekend.

Mainly clear skies today will transition to mostly cloudy conditions late tonight as the first disturbance approaches. Winds will shift out of the east Tuesday accompanied by low rain chances (20-30%) developing area-wide. As deeper moisture advects into the region Tuesday into Wednesday, rain chances will increase to moderate levels (40-50%) across South Texas then increase further during the day Wednesday, with high PoPs (70-80%) across the Victoria Crossroads.

Quantitative precipitation forecasts with this system are progged to range between 0.25" to around 1.0". The next cold front this weekend is likely to bring back freezing conditions behind the front with low to moderate chances for rainfall across the region.

Temperatures:

This morning, cold temperatures in the mid 30s to 40s will rebound quickly, warming into the mid 60s to low 70s this afternoon. Overnight lows will generally remain in the 50s through the remainder of this week.

High temperatures Tuesday will hover in the mid to upper 60s, then steadily climb through the end of the workweek, reaching the upper 70s to around 80 degrees by Friday. Cold temperatures are likely behind this weekend's front, with freezing temperatures showing up again early next week.

AVIATION

(12Z TAFS) Issued at 456 AM CST Mon Jan 19 2026

VFR conditions will continue through today. Guidance is beginning to hint at MVFR ceilings for LRD at the end of the TAF cycle, but since this is the first time we are really seeing this potential, will not include this at this time. Light and variable winds will turn become southwest this afternoon and increase with gusts to around 20 knots. Winds will then become light and variable once again late tonight.

MARINE

Issued at 1113 PM CST Sun Jan 18 2026

Onshore flow will return today and strengthen to a moderate (BF-4) breeze, occasionally nearing BF 5 through much of the week. Behind the weekend cold front, winds are expected to become fresh to strong (BF 5-6), with Small Craft Advisory conditions likely. Moderate rain chances over the waters mid-week are expected to increase to a high (80-90%) chance by Wednesday afternoon.

FIRE WEATHER

Issued at 1113 PM CST Sun Jan 18 2026

Minimum relative humidity values today are expected to recover to the (20-40%) range out west, further improving tomorrow along with ERC values and forecasted fire danger. The next front mid-week, is anticipated to be weak and likely to stall before making it across South Texas. As low level moisture returns this week, min RHs are progged to remain below thresholds. Thus, elevated fire weather conditions are not expected at this time.
