onshore flow will return to the area over the course of the day today, with east winds shifting to the southeast this evening. Increasing moisture thanks to this wind shift may result in the development of patchy sea fog ahead of the passage of a cold front late on Tuesday. Strong north winds will develop behind the front overnight on Tuesday into Wednesday with gusts to gale force possible at times as well as elevated seas. Low water levels could develop in the bays behind this front. Winds will diminish somewhat on Thursday and Friday but should still remain near small craft advisory levels.

SHORT TERM
(Today through Tuesday Night)
Issued at 242 AM CST Mon Feb 17 2025
Surface high pressure spanning the Plains slides east through the Mississippi River Valley today, allowing onshore flow to return this afternoon. Advection of warm/humid Gulf air will usher in a short warning trend, bringing highs in the upper 50s/60s. Rising moisture & cloud cover will limit cooling overnight, putting lows for Tuesday morning in the 40s/50s and lower 60s in some coastal spots.
WAA along with a strengthening LLJ will tap into abundant moisture, producing showers during the early morning hours of Tuesday.
Coverage increase with storms becoming more likely that afternoon as a warm sector moves onshore preceding the arrival of strong cold front. Shear is rather abundant across the region, and oriented parallel to the approaching cold front. On the other hand, instability remains rather meager, but could have time to build ahead of the front, which will not arrive in SE Texas till after Sunset. During the evening, coastal areas around Jackson/Matagorda/Brazoria could see SFC CAPE exceed 1000 J/KG with the advancing warm sector. Add in TEI values around 25 and Downdraft CAPE around 1000 J/KG, then there is at least a chance we could see some stronger/isolated severe weather with this FROPA. This aligns with SPC's thinking, which has portions of the area under a Marginal (level 1/5) risk for Tuesday. Main hazard of concern would be damaging wind gusts. Front should push offshore around or after midnight, ending the severe risk. Cold, dry and windy conditions fill in behind the front, with lows for Wednesday morning ranging from the upper 20s to mid 40s. Could need a Wind Advisory in some areas after the front, especially near the barrier islands.

LONG TERM
(Wednesday through Sunday)
Issued at 242 AM CST Mon Feb 17 2025
Behind the passage of the cold front discussed above late on Tuesday, strong northerly winds will develop across the area by early Wednesday. Sustained winds greater than 25 mph will be possible along the immediate coast through Wednesday afternoon, potentially requiring the issuance of a Wind Advisory. Further inland, expect sustained winds ranging from 15 to 20 mph with higher gusts at times. These elevated north winds will also provide a robust period of CAA, confining Wednesday's highs in the 40s inland and the lower 50s along the barrier islands (this is approximately 20 degrees below normal for late February). Of perhaps greater interest remains the low temperature forecast for Wednesday night. Deterministic and probabilistic guidance continues to signal a slightly warmer trend compared to that of a few days ago, with lows across portions of the Brazos Valley and Piney Woods in the lower 20s while Metro Houston sits just below freezing and the coast remains near 35. While this will only result in a hard freeze risk for limited portions of the area, it could nonetheless be a dangerous period cold when factoring minimum wind chill values in the teens to near 20s. Cold Weather Advisories and/or Extreme Cold Warnings could very well be needed for portions of the area, especially locations north of the I-10 corridor.
Strong high pressure over the Central CONUS will very gradually weaken and shift to the east through the end of the week, though its shift should not be significant enough for an onshore flow regime to develop. Highs for both Thursday and Friday are expected to remain confined to the 40s, though a weakening of CAA should result in marginal increases in overnight lows on each night (still, parts of the area could reach below freezing, especially north of I-10).
Our next chance of rainfall looks to arrive late Friday into early Saturday as the approach of a midlevel shortwave from the west induces the development of a weak area of low pressure along the TX Coastal Bend. As this system drifts towards the SE TX coast, increasing chances of rainfall enter the forecast through late Saturday.

AVIATION
(18Z TAF Issuance)
Issued at 1119 AM CST Mon Feb 17 2025
VFR conditions this afternoon with breezy SE winds. Conditions will begin to deteriorate to MVFR this evening, then IFR to LIFR late tonight into the rest of the TAF cycle. This is in response to an approaching cold front that will move through Tuesday afternoon and evening. Showers will be possible as early as overnight, with the best chances by mid-late Tuesday morning.
Given low confidence in timing and coverage of showers/storms, only kept PROB30 in TAFs.

Issued at 242 AM CST Mon Feb 17 2025
Winds will shift to the east today and later to the southeast tonight as onshore flow develops ahead of our next cold frontal passage on late Tuesday. Increasing moisture may result in the development of some patchy sea fog in the bays on Tuesday prior to the frontal passage. As the front pushes offshore late Tuesday into early Wednesday, strong north winds will develop in its wake along with building seas. Wind gusts to Gale force will be possible at times through Wednesday afternoon. Wind speeds will gradually diminish through the end of the week, but will continue to remain near Small Craft Advisory levels.
