Synopsis for the middle texas coastal waters.. Strong offshore will prevail tonight through Tuesday morning. There is a slight chance for showers tonight in response to an upper level disturbance. Wind and sea conditions will gradually improve from west to east Tuesday. Moderate north flow Tuesday evening will transition to weak northeast flow Wednesday, then weak onshore flow Wednesday night as high pressure moves to the northeast. As onshore flow becomes weak to moderate Thursday evening into Friday morning, increasing moisture will contribute to a few showers by Friday ahead of a cold front. Some sea fog could develop later this week until dry offshore flow arrives Friday night behind the front. Winds will become moderate to strong Saturday morning, decreasing to weak to moderate flow front the northeast by Saturday evening.

AVIATION (Updated for 00Z Issuance).

Ceilings have raised to VFR for COT/LRD and will persist through the period. ALI is now in MVFR and with the last lingering showers moving eastward, expect to become VFR overnight. VCT/CRP are in IFR as a swath of light to moderate rain showers move through the Coastal Bend and Victoria Crossroads. Expect MVFR/IFR to continue in association with the rain over VCT/CRP for the next few hours. Conditions will improve west to east through the period. How early VCT/CRP will improve to VFR is of low confidence at this time. However, there is greater confidence in VFR conditions prevailing for all sites by 18Z. Northerly winds will remain moderate to strong through the morning hours for the Coastal Plains.

PREV DISCUSSION. /Issued 353 PM CST Mon Mar 1 2021/

SHORT TERM (Tonight through Tuesday Night) .

An upper level disturbance will provide synoptic scale lift tonight through early Tuesday morning. Elevated convection associated with the upper disturbance, and light rain associated with isentropic lift, will persist this evening/early tonight before moving offshore. Cooler during the period, with minimum/maximum temperatures similar to the SREF ensemble mean values.

LONG TERM (Wednesday through Monday) .

Long term period remains quiet as high pressure continues to settle in. A warming trend will continue Wednesday through the end of the week as westerly winds bring in warm, dry air into the region. Highs through the end of the week will generally be in the 70s to low 80s. A mid-upper level low will traverse the TX Panhandle Friday and clip the easternmost portion of the state. As the low tracks east, it will send a cold front into South Texas. Kept slight chance of PoPs as the front approaches. Isentropic lifting at the 295K-300K levels could aid in the development of isolated showers early Friday ahead of the front, particularly along the Coastal Plains and east where PWAT values are the greatest. At this time the environment does not look conducive to convective activity. Northwesterly winds behind the front will draw cooler air into South Texas. Highs on Saturday will be in the mid 60s to low 70s. Onshore flow returns Sunday, and temperatures will begin a warming trend once more as warm moist air is advected into the region.

MARINE .

The cold front has moved across the coastal waters. An SCA remains in effect areawide, ending at 15z over the bays, and 21z over the coastal waters. SREF probabilities of sustained wind >25 knots high over the coastal waters, mainly 06-12z Tuesday, which suggests that frequent gusts to gale force could occur. However, coordinated with BRO will defer the decision on a Gale Warning to the next shift. Weak northeasterly flow is expected for Wednesday, becoming weak onshore flow Wednesday night as high pressure departs to the northeast. As onshore flow becomes weak to moderate Thursday evening into Friday morning, increasing moisture will contribute to a few showers by Friday ahead of a cold front. Some sea fog could develop later this week until dry offshore flow arrives Friday night behind the front.
