SHORT TERM
(Tonight through Sunday night)
Issued at 238 PM CDT Sat Sep 7 2024
A cold front has moved to the upper TX coast and stretches back across the Coastal Plains to the Rio Grande near Eagle Pass. Breezy northeasterly winds are moving in behind the front. These winds are bringing drier air to South-Central Texas. Dewpoints are five to ten degrees lower than 24 hours ago. High pressure will continue to dominate during the short term. Northeasterly flow will continue.
Surface winds will drop off to less than 10 mph after sunset this evening. Temperatures will drop to the 50s and 60s overnight making for one of the coolest nights we've seen in some time. Temperatures Sunday will also be cooler than today with highs mostly in the 80s with parts of the Rio Grande Plains reaching the lower 90s. Winds will be breezy again Sunday from the northeast. Another cool night Sunday night with lows a couple of degrees lower than tonight under mostly clear skies and light winds.
LONG TERM
(Monday through Saturday)
Issued at 238 PM CDT Sat Sep 7 2024
The northeast to east winds at low levels pattern will continue into much of the work week as a tropical disturbance moves toward South TX from the coast of Mexico. The flow should be light Tuesday as the system remains well to the south, leading to a slightly warmer afternoon and a bit more moisture advecting from East TX. The moisture gradient is tight in the afternoon so there could be decent amount of shower activity over the Coastal Prairies, but probably just an isolated cell or 3 closer to the I-35 Corridor. The 12Z deterministic runs seem a little extra bullish on the development of the tropical system despite a fair amount of land proximity, so we're a bit skeptical of the elevated PoPs for Wednesday, but perhaps only by a little. Western counties will likely remain void of rain chances for this passing system, but a few rounds of afternoon showers can't be ruled out for a 30-40 percent type day Wednesday for our more populated areas. We may need to consider some higher wind gusts for Wednesday afternoon going forward as well. By Thursday, we should be on the back end of the disturbance with a decreasing trend again for PoPs. Friday and Saturday, we should see shortwave ridging aloft over Central TX and perhaps the warmest days of the week.
