Long Term
(Thursday night through next Tuesday) Issued at 308am CST Wednesday Feb 19 2025

Key Messages:

- Western Gulf surface trough will lead to increased rainfall chances across the Coastal Bend.

- Near-freezing temperatures leading to low chances (<20%) of ice developing on elevated surfaces across northern Brush Country/Victoria Crossroads.

- Warm up trend from Monday will lead to above-normal temperatures by mid-week.

Thursday night, a surface trough in the Western Gulf will extend its axis into the Middle Texas coast, leading to increasing chances for showers, initially in the open waters and offshore Padre Island. By Friday morning, these showers will begin to bless our coastal zones and especially along the barrier islands. We will rinse and repeat this cold and damp February day through Saturday, when the trough begins to break down, allowing showers to end from west to east throughout Saturday night and Sunday morning. In terms of overall accumulations, the probability of receiving a quarter-inch for the Coastal Bend and the Victoria Crossroads is moderate to high (50- 70%), decreasing to 10-30% chance for inland areas. The barrier islands have the greatest potential for reaching half-inch accumulations, though the confidence in this threshold is lower (30- 50% chance).

Temperature-wise (and thus, precipitation type-wise), lows Friday morning will begin to moderate compared to previous nights, dropping as low as the freezing mark along the Coastal Bend and into the Brush Country. The probability of dropping below the 32F, per the NBM, has a moderate to high chance (50-70%). Wind chill-wise, Friday morning's values will generally be in the mid to upper 20s to the low 30s. Any rain showers/drizzle that moves through these regions have a high chance of primarily remaining as rain, though any wet spots/areas of drizzle has the potential of freezing on elevated surfaces. Sufficient warming on Thursday afternoon likely will keep road surface temperatures above freezing, but we will have to closely monitor these values. Any pre-treated surfaces will provide better assurance of any black ice forming. Caution should still be exercised if driving during this time frame.

From Saturday, the 500 hPa pattern suggests that ridging over the Intermountain West will keep increasing its influence over South Texas, resulting in temperatures moderating back to near-average values on Sunday. By Monday, temperatures climb back into the 80s across the Coastal Bend and possibly into the low 90s across the Rio Grande Plains.

Marine
Issued at 308am CST Wednesday Feb 19 2025

Very strong north winds will continue through the morning. A Gale Warning is in effect until 1 pm this afternoon for frequent gusts 35 to 40 knots. Winds are expected to drop below gale conditions this afternoon but will remain at Small Craft Advisory levels through Thursday afternoon. Winds will diminish briefly Thursday night before Small Craft Advisory conditions develop once again Friday morning. By Friday afternoon, strong to very strong winds bring seas back to 6 to 8 ft through Saturday morning. Winds will diminish to weak to moderate offshore flow by Sunday. A moderate to high (40-80%) chance of showers is expected late Thursday night to Sunday morning. Weak to moderate onshore flow returns on Monday, increasing to moderate onshore flow Tuesday night.
