moderate to strong northeast winds and elevated seas will remain in place over the coastal waters through this afternoon. Rain chances will be increasing overnight with unsettled weather expected through the weekend. 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 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
(Today through Sunday Night)
Issued at 309 AM CST Sat Dec 7 2024

With a closed upper low over the Arizona-New Mexico border, we find ourselves underneath a flow of moisture and disorganized vorticity aloft. And with moisture through the column increasing, we find ourselves already in a stream of sporadic showers and even an isolated lightning strike around the area very early this morning.

While one relatively larger pulse of vorticity is making its way off to the northeast and out of the area, there is plenty more where that came from, blindingly obvious from just a quick glance at water vapor satellite imagery. Because of that, varied PoPs are with us through today and tonight. For the most part it boils down to "chance" PoPs as these vort blobs are not particularly organized, nor do we yet have a solid forcing mechanism for convection. The general character for most of the day will be light to moderate showers, a stray bolt of lightning - mainly over the Gulf and near the coast - on and off through today. However, I do try to get a bit more aggressive when there's better consensus in a stronger bit of vorticity aloft passing through, which should engender more widespread showers like we saw earlier tonight. The next one of these moves in from the west later this morning (around 8 am or so), and makes its way northeastward across the area through the mid- afternoon.

We should see a change in that character late tonight into Sunday morning. By this time, a coastal trough will transition to a coastal low with an attached warm front, scraping their way along the upper Gulf coast. At the same time, a very subtle boundary looks to make its way roughly west to east across inland portions of the area. For the past several nights I've been calling this a weak cold front, but I don't know that I can reasonably call it that anymore. With no upper support and relative strong surface ridging over the Southeast US, this boundary is easily stripped away from the low it was attached to, way up over Canada. There's really not much of a windshift left. There is some lingering frontogenesis just above the deck, plenty of moisture, and the continued stream of vorticity aloft, which I do think should be enough to help generate a somewhat coherent swath of showers and isolated thunderstorms. The bigger upper trough is making its way in from the west, but is still over Oklahoma by tomorrow afternoon, so I don't see it contributing a lot to supporting showers or storms.

Sunday night will see the process of rain coming to an end from west to east as the upper trough makes its way towards the Ohio Valley, shoving the southwesterly stream of moisture and vorticity aloft off to our east. Rain chances should be expected to linger along the immediate upper Gulf coast (more Galveston Bay area than Matagorda Bay) and over the Gulf as the upper trough leaves behind some leftovers over this area.

Temperature-wise, things are pretty straightforward. With a nearly full stretch of clouds and intermittent rain, we'll see a very compressed temperature range through the weekend. Look for highs in the 50s and 60s today fall only 5-10 degrees by the time we see low temps tonight. Sunday looks to get a little warmer due to the higher temp floor, but highs in the 60s to just above 70 degrees are the expectation here. Sunday night looks pretty similar to Saturday night. The coolest temps should be in the northwest where we have at least some chance of getting small breaks in the clouds, while overcast holds tight at the coast.

LONG TERM
(Monday through Friday)
Issued at 309 AM CST Sat Dec 7 2024

Another weaker shortwave trough is progged to push through Texas on Monday, though rain chances are expected to trend downward as the primary moisture axis shifts offshore into the NW Gulf, lowering PWs inland. The shortwave, in conjunction with a deeper trough digging through the Rockies/Plains will also shove a cold front into SE Texas Monday evening through early Tuesday morning.
Cooler, drier and gusty conditions fill in behind the front, though a reinforcement of even cooler/drier air will filter in during the day on Tuesday as surface high pressure fills in across the Southwest/Texas.

LREF ensemble members show good agreement pertaining to initial frontal timing, with 71% of members indicating that the front won't reach College Station till after 6 PM. With the front arriving after peak heating, highs for Monday should be in the mid 70s/lower 80s.
Behind the front, Tuesday highs will be in the upper 50s/60s. The combination of CAA and clear skies will result in an even greater drop in overnight temperatures, bringing lows in the 30s/40s for Tuesday & Wednesday nights.

For Wednesday morning, there is a high (>90%) chance that temperatures will drop to or below freezing across portions of the Brazos Valley & Piney Woods area. For Thursday morning, these chances are even greater, covering a large portion of SE Texas including areas near Shepherd and Cleveland. It is likely that Freeze Watch/Warnings will be needed for these portions of SE Texas for Wednesday/Thursday morning.

Surface high pressure slides east early on Thursday, bringing east/southeasterly flow that morning and thus allowing WAA and moisture advection to resume. Rain chances and temperatures rise through the end of the work week, with highs reaching the mid 60s/mid 70s on Friday.

AVIATION
(12Z TAF Issuance)
Issued at 550 AM CST Sat Dec 7 2024

Very challenging forecast ahead, amendments seem virtually certain. Widespread VFR for now, but with numerous showers and decreasing cloud bases already afoot. Should see gradual degradation, with a stronger burst of showers and maybe even a stray lightning strike late morning into afternoon. Not enough confidence for any TSRA or VCTS, but be on the lookout for them to enter through amendments or the 18Z cycle if needed. CIGs continue to slip to IFR or lower tonight, as well as patchy/areas fog with IFR or lower VSBY as well.

MARINE
Issued at 309 AM CST Sat Dec 7 2024

Winds of 15 to 20 knots and seas of 4 to 7 feet are expected through early today, weakening and veering east/southeasterly this afternoon. Shower and thunderstorm coverage should slowly increase throughout the day. With rising moisture and weaker winds, sea fog could develop as early as Sunday morning with any breaks in rainfall. A cold front will push off the coast during the early morning hours of Tuesday, ending the threat of sea fog and bringing strong northerly winds and high seas in its wake. Additional Small Craft Advisories will likely be needed from Tuesday through portions of Wednesday as winds approach 20 to 30 knots and seas rise to 5 to 9 feet. Winds and seas diminish late Wednesday into Thursday.
