| Synopsis for Middle Texas coastal waters from Baffin Bay to Matagorda ship channel - GMZ200 326 AM CST Tue Mar 2 2021 Strong northerly flow this morning with Small Craft Advisory conditions will taper to moderate levels from west to east this morning and afternoon. North winds become weak to moderate tonight as high pressure draws closer, before turning northeasterly and easterly on Wednesday and remaining mostly weak. Weak to moderate onshore flow continues Wednesday night through 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, becoming more moderate as flow shifts to onshore by Sunday evening. |
| Area Forecast Discussion National Weather Service Corpus Christi TX 1052pm CST Monday 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 Probability of Precipitation 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 (Precipitable Water) 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 Discussion The cold front has moved across the coastal waters. An SCA (Small Craft Advisory) 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. NOAA Corpus Christi TX Office: Watches - Warnings - Advisories TX...None.
