Synopsis for the middle texas coastal waters.. A weak to moderate onshore flow this evening will become weak overnight as a frontal boundary moves into south texas early Thursday morning. Another episode of sea fog over the near shore waters is expected tonight through Thursday morning. The fog may move into the bays also. Isolated showers will be possible Thursday into Thursday night. A brief improvement in the fog is expected Thursday afternoon but the fog should return Thursday night. Weak to moderate onshore winds will persist through Sunday night before a cold front comes through Monday morning. Winds will strengthen to moderate to strong and shift out of the northeast in wake of the front, causing small craft advisory conditions for the offshore waters Monday night through Tuesday. Isolated showers are possibly over the nearshore waters Friday. Isolated showers are then possible over all waters Monday through Tuesday in association with the cold front.

AVIATION.

VFR this evening is very likely to collapse to IFR at CRP, VCT and ALI before midnight as low ceilings and some fog advance inland. These decks should reach the western terminals by 08Z-09Z with a window for VFR returning at LRD by mid-afternoon. Elsewhere, MVFR and IFR ceilings should struggle to break out during the afternoon even as a weak cold front drifts south and eventually stalls SW-NE over the region. SE winds at CRP ahead of this front should become very breezy during the afternoon.

PREV DISCUSSION. /Issued 349 PM CST Wed Feb 24 2021/

SHORT TERM (Tonight through Thursday Night) .

The cold front over central Texas is expected to continue sagging slowly south tonight and move into the northern Brush Country to near Victoria before 12Z Thursday. With light southeast to east winds in advance of the front, fog that forms over the coastal waters will move into the coastal plains overnight and linger through late Thursday morning. Weak low level warm air advection could lead to isolated showers late tonight mainly over the Victoria Crossroads.

NAM/CONSShort models show the frontal boundary sagging south to just south of Victoria to near Laredo Thursday afternoon before stalling. Slightly cooler temperatures are expected north of the boundary while above normal temperatures will continue south of it. Weak convergence/lift along with enough low level warm air advection will provide a chance of light showers along and north of the boundary Thursday.

A short wave trough will move across the Four Corners region on Thursday and into Oklahoma/north Texas Thursday night. The frontal boundary will become oriented north-northeast to the south-southwest from Beeville to Hebbronville Thursday night. Low level warm air advection will increase Thursday night as southerly flow increases to 25-35 knots. Better chances for light rain showers will be north of the boundary. Fog will also be possible again over the coastal regions.

LONG TERM (Friday through Wednesday) .

There is still some uncertainty regarding where the weak front will be positioned on Friday. Considering all guidances, will keep the front bisecting the CWA northeast to southwest through the day Friday before moving northward as a warm front Friday night. Kept isolated showers over the Coastal Plains and Coastal Bend Friday, Saturday, and Sunday due to onshore flow with plenty of low-level moisture and isentropic lift. Sunday, CAPE approaches 1000 J/kg over the Victoria Crossroads with CIN less than 40 will included a slight chance of thunderstorms as well. A strong mid-level closed low will move across New Mexico into North Texas Sunday night through Monday night, pushing another cold front through South Texas. This front seems to be stronger and pooling in plenty of moisture throughout the atmosphere ahead of it, with PWATs approaching record values of over 1.8" on Monday according to the GFS. Plenty of moisture, lift support from the front and mid-level energy, will allow for scattered showers and thunderstorms to develop Sunday night through Monday. Rain showers may linger in wake of the front Monday night into Tuesday morning.

Highs throughout the extended will likely range from the 70s to low 80s with cooler days Friday, Monday, and Tuesday. Lows remain in the 60s through Sunday night, then drop to the 50s Monday night and Tuesday night.

MARINE .

A weak to moderate onshore flow this evening will become weak overnight as a frontal boundary moves into south Texas early Thursday morning. With dewpoint temperatures in the upper 60s moving across the cooler shelf waters with readings in the mid to upper 50s, expect another episode of sea fog over the near shore waters later tonight through Thursday morning. The fog may move into the bays also. Isolated showers will be possible Thursday into Thursday night. A brief improvement in the fog is expected Thursday afternoon but the fog should return Thursday night.

Weak to moderate onshore winds will persist through Sunday night before a cold front comes through Monday morning. Winds will strengthen to moderate to strong and shift out of the northeast in wake of the front, causing Small Craft Advisory conditions for the offshore waters Monday night through Tuesday. Isolated showers are possibly over the nearshore waters Friday. Isolated showers are then possible over all waters Monday through Tuesday in association with the cold front.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
