DISCUSSION

Issued at 107 PM CST Fri Jan 9 2026

Scattered shower and isolated tstm coverage is on an uptick this afternoon in advance of the next front that will be moving into the region later today and overnight. There's plenty of cloud cover out there now, but sat pix are showing some intermittent breaks. With a bit more destabilization on tap, we'll need to keep an eye out for the potential of a few embedded strong-severe cells to emerge. In addition, given the high PW's in place and some regeneration/training, I wouldn't be overly surprised to see a narrow swath of 1-3" rainfall amounts emerge somewhere generally north of the I-10 corridor between now and early-mid evening. Given the ground conditions, not overly concerned with a widespread FF threat, but could see some very localized street flooding if, and where, it decides to do it in a short time period. Frontal boundary catches up with the ongoing precip this evening and should see a more progressive sewd movement thru the metro area in the late evening and off the coast 1-3am.

Precip should mostly taper off behind the front for majority of the area, though we could see some lingering showers closer to the coast Saturday until we see a deeper northerly flow fill in. Much cooler temperatures and breezy north winds are expected across the region Saturday. Winds will gradually taper off Saturday night and Sunday. Fair, seasonable wx is anticipated into early next week.

A portion of today's upper trof will cutoff and retrograde back toward Baja this weekend...then eject back ewd and across the area toward midweek. Guidance isn't too bullish in regards to moisture recovery between now and then...hence low/nil advertised POPs at this time, but may need to add some down the road. Look for another midweek front after this shortwave passes. 47

AVIATION

(00Z TAF Issuance) Issued at 530 PM CST Fri Jan 9 2026

Scattered SHRA/TSRA from IAH northward will force VC mentions for the topline. As that activity wanes, focus will turn to cold front with broken line of showers and storms along it - TEMPOs and/or prevailing for a couple hours mark this frontal passage, though PROB30s are used at LBX and GLS with a little uncertainty about storms surviving all the way to the coast. GLS also has potential for sea fog until frontal storms arrive to disperse it.

After front passes, winds switch to northwesterly/northerly and become strong and gusty by morning. These winds and return to VFR will be the main issue for the remainder of the forecast period.

MARINE

Issued at 107 PM CST Fri Jan 9 2026

Patchy fog will remain possible in the nearshore Gulf waters and southern bays in advance of the next cold front that will be pushing off the coast tonight. Showers and isolated storms will accompany the front. We should see a wind shift along the coast around or shortly after midnight, followed by increasing speeds as we head into the 4-6am timeframe. Small Craft Advisories have been issued for late tonight & Saturday. Moderate to occasionally strong north winds and building seas are anticipated Saturday and Saturday night before gradually diminishing Sunday. Light, mainly onshore flow is anticipated early next week followed by another cold front around Wednesday. 47
