KEY MESSAGES

- Above normal temperatures through Friday. Many locations will flirt with some record highs.

- Patchy/areas of fog tonight, but probably less coverage and not as dense as the previous few nights.

- Some rain chances re-enter the forecast Thursday followed by higher chances Friday in advance of the next cold front Friday night.

DISCUSSION

Issued at 106 PM CST Wed Jan 7 2026

Upper low situated near Baja will fill and advance ene tonight and across the Plains Thursday. In advance, we'll see a tightening llvl pressure gradient leading to some increasing southerly wind speeds. After some potential redevelopment of sea fog this evening, these strengthening winds will probably limit the overall coverage of inland fog overnight compared to what we've seen the past few nights. These same winds will also keep readings from falling much...with overnight lows only falling into the 67-70F range for most locations.

Though PW's will be trending upward and closer to 1.5" Thurs, and some healthy shear will be present, forecast soundings show a substantial warm nose situated between H85-H7 which looks like it'll be pretty difficult to be overcome. Assuming this is the case, would anticipate that precip would mainly be in the form of isolated-scattered light WAA streamer-type shra versus tstms. With a warm start to the day, look for highs to flirt with records again. Breezy south winds 10-20g25mph can be expected.

Another upper trough and associated prefrontal trof approaches on Friday. Even higher PW's (~1.7) will pool in advance. Though shear won't be as impressive as Thursday, overall instability should be higher with less capping and a somewhat favorable upper jet position. This should set the stage for better chances of showers and storms across the area...generally north of I-10 during the morning & afternoon and further south in the afternoon and evening. Cannot rule an isolated strong-severe cell or two with winds/hail the primary threat.

Prefrontal trof pushes off the coast Friday evening, mostly ending rain chances. Cold front itself should follow shortly thereafter leading to drier and more seasonable weather conditions this weekend into early next week.

High pressure moves off to the east late Monday and some coastal troffiness looks to set up heading into Tue-Wed. 47

AVIATION

(12Z TAF Issuance) Issued at 513 AM CST Wed Jan 7 2026

Dense fog and low cigs are resulting in widespread IFR/LIFR conditions this morning. These conditions should slowly improve as the morning progresses. We expect most locations to be VFR by the afternoon. Winds should increase somewhat from the south to southeast during the afternoon hours. Expect decreasing cigs/vis once again overnight, with widespread MVFR likely. Could have areas of IFR as well.

MARINE

Issued at 106 PM CST Wed Jan 7 2026

Some lingering patches of dense fog may persist into the early afternoon hours in parts of Galveston Bay and adjacent Gulf waters. This fog will probably expand in coverage during the early and mid evening hours. However, as the night progresses, guidance indicates stronger winds developing which could allow for improved visibility overnight, though there is forecast uncertainty. With increasing onshore winds tonight and Thursday, anticipate building seas and caution or advisory conditions developing offshore. Winds will diminish Thursday night and we will again need to monitor the fog situation. The next cold front is forecast to push off the coast late Friday night with moderate to strong offshore winds and building seas in its wake. 47
