Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
generally moderate east to southeast winds and elevated seas will prevail through this evening. Winds and seas should decrease during the overnight hours. Scattered showers and isolated storms will continue tonight through Sunday. With a warm moist air mass settling over the area, sea fog could develop as early as Sunday morning with any breaks in rainfall. A strong cold front will push off the coast during the early morning hours of Tuesday, ending the threat of sea fog and bringing strong offshore winds and high seas in its wake. Additional small craft advisories will likely be needed from Tuesday through portions of Wednesday.

New AVIATION

SHORT TERM
(This evening through Sunday Night)
Issued at 337 PM CST Sat Dec 7 2024

A fairly busy synoptic pattern has brought us what has proven to be a fairly wet and cool day thus far across SE TX, though rainfall rates have remained relatively low thanks to a distinct lack of instability (current sfc CAPE analysis indicates values under 250 J/kg area wide). Despite this, we remain in a favorable pattern for some additional rainfall tonight and tomorrow before the arrival of our next cold front early next week.

The passage of a few weak embedded vorticity maxes over the past 12-18 hours have supported the development of today's scattered showers that have brought measurable rainfall to most of the area.
Meanwhile, a weak coastal low to our southwest continues to approach the SE TX coast, and radar continues to indicate showers associated with this system's warm frontal boundary just offshore this afternoon. HiRes guidance shows the axis of highest rainfall shifting out of the area over the next few hours as the aforementioned shortwave energy concurrently shifts to the east.
However, additional rainfall arrives tonight and into tomorrow morning as the coastal low/warm front pushes further to the north while a robust midlevel trough approaches from the NW. This should result in most of the area yet again picking up measurable rainfall. However, much like yesterday, instability/forcing remain weak and rainfall rates should remain low. The thunderstorm threat should remain fairly isolated as instability remains highest well offshore.

One other impact to note is the potential for marine fog as a plume of deeper moisture arrives with the approach of the coastal low. Surface dew points in the mid/upper 60s and Gulf temperatures in the 50s should support some fog development tonight and into tomorrow, perhaps lingering into Monday (see Marine section).

The temperature forecast remains on track with cloud cover inhibiting overnight cooling, keeping lows in the 40s to low 50s inland and the upper 50s along the coast. The arrival of warmer and more humid air with the coastal low tomorrow will push highs into the 60s and overnight lows into the 50s/near 60 along the coast. The arrival of a more humid airmass with this system should be quite noticeable, as dew points should push into the upper 50s/60s tomorrow.

LONG TERM
(Monday through next Friday)
Issued at 337 PM CST Sat Dec 7 2024

The progressive/active weather pattern will continue into Mon with the middle of the week becoming drier and much cooler; then by the end of the week, warming temperatures and maybe the return of some low POPs.

By Mon, SE TX will be on the back side of the exiting coastal trough with a warm/humid air mass in place across the area. The best chance for showers/thunderstorms are going to be mainly along the coast and our Gulf waters. Highs to range from the upper 70s to the lower 80s.
But north of the CWA, another surface low is progged to develop/move across the Southern Plains in conjunction with another short wave at the mid/upper levels. This system is expected to be weaker (then the weekend one), but should be enough to help drag a cold front through the state and our CWA Mon night. With the deepest moisture remaining at to just off the coast, POPs with this FROPA should remain at/near the coast. The main issue with the front looks to be post-frontal as cold Canadian air settles over the region. There's a good chance the northern portions of the FA could see our first freeze of the season Tues night (and likely again Weds night as well).

As the strong surface high transitions east of the region Thurs and Fri, look for slowly warming temperatures to end the week. Moisture returning could also herald the return of low POPs by Fri/Fri night.

AVIATION
(00Z TAF Issuance)
Issued at 537 PM CST Sat Dec 7 2024

As the evening hours approach, expect a downward trend in ceilings and visibilities as scattered rain showers continue to push through Southeast Texas. Widespread IFR ceilings are expected overnight along with the potential for VLIFR ceilings. On top of that, patchy fog may cause decreased visibilities as well outside of the passing rain showers. It's difficult to time out the exact window for the highest coverage of rain showers, but the best consensus looks to generally be Sunday late morning into the afternoon (~15Z to 00Z). Additionally, a rather strong southwest to northeast oriented LLJ will develop over the region and lead to LLWS generally between 35-40 kts on Sunday afternoon. IFR ceilings will linger throughout the day on Sunday, but there is potential for some western sites to see a brief return to MVFR before sunset.

MARINE
Issued at 337 PM CST Sat Dec 7 2024

Moderate (to occasionally strong) E/SE winds will persist across the coastal waters this evening. With the SCA expiring earlier this aft- ernoon, have gone with Small Craft Exercise Caution flags for all of our Gulf waters through this evening. Winds/seas are expected to de- crease overnight as the gradient weakens further
Otherwise
shower and thunderstorm coverage will continue to increase tonight, through tomorrow. The increased low-level moisture and weaker winds could be favorable for the development of sea fog late tonight/early tomorrow morning...and again tomorrow night/early Mon morning.

A strong cold front remains in tap to push into the Gulf during the very early morning hours of Tues. This should end the threat of sea fog...as well as strong NW/N winds and elevated seas in the wake of the front. Additional Small Craft Advisories are likely going to be needed Tues/Weds. 41
