SHORT TERM (Tonight through Wednesday Night).

An upper level disturbance was moving across the Rockies/approaching the Plains today, with a N-S ridge axis near/along the Mississippi Valley. A surface ridge was located over the SERN CONUS and surface low pressure over Plains/western TX, as expected from the foregoing upper pattern. As a result, onshore flow was occurring over the CWA/adjacent Waters. Deterministic runs predict the upper disturbance to move slowly across the Plains tonight/Wednesday, and onshore flow will persist over the CWA, yet PWAT values are predicted to remain near to below normal. Limited moisture combined with significant CIN will preclude convection over the CWA during the period.

Patchy fog may over portions of the Victoria Crosroads during the 09-13z Wednesday period, consistent with deterministic NAM prediction of a vertical profile conducive to such, and with SREF probabilities.

Astronomical tides expected to rise slightly during the period in resposne to the New Moon. Tide level at Bob Hall Pier rose to 1.86 this afternoon (high tidal cycle occurring at this time), yet just fell somewhat. However, anticpiate that the tide level at Bob Hall Pier will approach 2ft MSL Wednesday afternoon (the P-ETSS adds credence), yet will defer to later shifts to reconsider issuance of a CFW.

LONG TERM (Thursday through Tuesday).

A west to southwest upper flow aloft combined with a series of embedded short waves will continue to track eastward across the region through the period. Moisture will remain limited with PWATs at or below 1.5 inches for Thursday. Models prog a slight increase in moisture in the mid and upper levels across the western CWA Thursday night and Friday with PWATs increasing to around 1.6-1.7 inches. With a short wave progged to move across S TX during that time frame, there may be enough mid level moisture for a few sprinkles, but minimal CAPE and high CIN will keep convection from developing. Have gone with silent 5-10 PoPs across the western CWA and along the coast with 20 PoPs over the Coastal Waters where deeper moisture and instability will be located.

Moisture continues to gradually increase through the weekend with short waves tracking across the region leading to a slight chance of convection along the coast and over the waters. Less moisture and instability farther inland should preclude precipitation from developing in those areas.

By Monday, models prog PWATs to increase to 2.0-2.3 inches across S TX. However, a mid level high pressure is progged to track from Baja CA northeastward toward E TX, which will help suppress convective development across S TX. There remains some upper level weakness across S TX on the southern periphery of the upper high, which should be enough to combine with the deeper moisture to produce isolated convection along the sea breeze.

As for temperatures, a gradual warming trend is expected through the period with temps near to slightly above normal by the weekend.

The PETSS continues to forecast tides to reach 2ft MSL at Bob Hall Pier during times of high tide through Saturday. Will continue to monitor tidal trends for possible minor coastal flooding.

MARINE.

Generally weak onshore flow expected tonight through Wednesday, with no significant precipitation. Weak to moderate onshore flow is expected Thursday through Saturday before increasing to more moderate levels by Saturday night and Sunday. Isolated showers and thunderstorms will be possible Thursday through Sunday.
