KEY MESSAGES

- Light freeze until mid morning across northern parts of the area. There is a non-zero chance of a few isolated pockets of freezing fog toward sunrise.

- Cold front pushes through this evening, but Arctic air really doesn't filter in until Friday night. - Hard freezes for northern parts of the area Friday night & most of the region Saturday night.

DISCUSSION

Issued at 1208 AM CST Thu Jan 29 2026

Look for another cool start to the day. Latest guidance isn't quite as bullish with the freezing fog potential between now and mid morning near the Piney Woods/Brazos Valley (~30%), versus some of the earlier (50%+ runs), but the potential is there so some caution is advised for the early morning commute. Otherwise, we should see a nice warm up with readings making their way into the 60s with the sw llvl winds ahead of the next incoming front. This dry front will push thru the region this evening.

Cold, Arctic high pressure will spill southward into SE TX Friday night through Saturday Night. Corresponding temps will take a dive back down into hard freeze territory for the Piney Woods area Friday night and daytime highs on Sat only between 36-45F for all the area. By Saturday night almost all inland locations will see a hard freeze with lows in the 17-22F range. Cannot rule out a Cold Weather Advisory or two.

Ridging transitions to the east later Sunday, with a warming/modifying trend ensuing early next week. Next chance of rain comes into play Tuesday or Wednesday as moisture recovers with the onshore flow, we see a somewhat messy upper pattern, and another front getting closer to the region. 47

AVIATION

(12Z TAF Issuance) Issued at 507 AM CST Thu Jan 29 2026

Patchy fog will generally bring MVFR to IFR FLs early today with some spots potentially reaching LIFR briefly. A few areas are near or at the freezing mark, thus freezing fog will be possible in some spots early today. Fog should clear later this morning with VFR conditions returning. A dry cold front should push through the area this evening, moving off the coast around midnight. Breezy north to northwest winds develop behind the front.

MARINE

Issued at 1208 AM CST Thu Jan 29 2026

Light winds and low seas will prevail through the day. The next cold front will push off the coast late this evening followed by moderate north winds and building seas. Small Craft Advisories may be required late tonight. With a reinforcing shot of cold, Arctic air anticipated Friday night, winds and seas should further increase into Saturday, then gradually decrease Sunday. On the bays, already low astronomical tides will produce some negative water levels this week, even more so Friday night into the weekend with stronger north winds in place. Low Water Advisories are already in place. 47
