| Area Forecast Discussion National Weather Service Brownsville TX 400am CDT Wednesday Mar 29 2023 ...New SHORT TERM, LONG TER Marine .SHORT TERM... (Today through Thursday) Issued at 354am CDT Wednesday Mar 29 2023 Shortwave perturbations are currently moving through Deep South Texas this morning. Light to moderate rainfall is still ongoing across the CWA. MFE broke the daily maximum rainfall with 2.91 inches of rain falling yesterday. Replaced the old record of 0.86 of an inch set in 1957. Rain is forecast to taper off by late morning with another round of stratiform rain occurring this afternoon into tonight. Some showers could produce heavy rainfall again today as PWAT (Precipitable Water) values are still elevated near 1.5 to 1.6 inches which is still in the 90th percentile for the CWA. However, CAPE values have decreased significantly and convection and hail is not expected today. By Thursday, conditions are forecast to be much drier as mid- level high pressure builds over the Gulf of Mexico. As mentioned in the previous forecast discussion, temperatures have trended cooler and cooler for today and tomorrow. Since NBM still seems to be running a bit warm, blended previous forecast/CONSShort to keep consistency with the cooler temperatures. Highs today are forecast to reach the mid 60s due to overcast skies. Tonight, lows will be in the upper 50s and lower 60s. Thursday will be almost 20 degrees warmer in the 80s with partly cloudy skies. High Risk of rip currents is also forecast for today and tonight. Long Term (Thursday night through Tuesday) Issued at 354am CDT Wednesday Mar 29 2023 A sharp, positive tilt 500 mb trough will dig south from the Pacific Northwest into the Desert Southwest on Thursday. This feature will support development of a storm system over the central high plains. The storm will lift northeast over the Plains toward the upper midwest Friday. Locally, a strong southeast return flow will develop. High temperatures on Friday will trend higher, from the upper 80s to mid 90s. The tail end of an associated cold front will move into Texas Friday, stalling and stretching northeast to southwest over the Coastal Plains and northwest sections of the CWA (County Warning Area) Friday night and early Saturday. Moisture with the front appears to be limited but a few showers could materialize over the upper Valley and Ranchlands. That should be the extent of rain chances in the long term, however. Moisture could become a little better focused once return flow takes hold on Saturday and the front begins to retreat north. However, convection chances by that time will be primarily limited to north of the CWA. A similarly sharp, positive tilt mid-level short wave trough will dig south into the Greta Basin area next Monday and Tuesday, generating another storm system over the central high Plains, and supporting locally breezy southeast return flow. Temperatures will trend higher Thursday and Friday with a temporary respite Saturday due to the nearby cold front. The warming trend will resume Sunday and early next week with highs in the 90s to a few supra century mark readings out west by Tuesday. Marine Issued at 354am CDT Wednesday Mar 29 2023 Today through Thursday: Light to moderate showers are ongoing and will taper off by late morning and restart this afternoon. Winds will remain breezy through the short term period and will be northerly for today but turn southeasterly once high pressure builds over the Gulf of Mexico tomorrow. Seas remain elevated today and have a Small Craft Advisory for near and offshore waters (0-60nm) until 6am CDT. Then, only a SCA (Small Craft Advisory) for the offshore waters (20-60nm) until 4pm CDT. Thursday night through Sunday night: Strong high pressure over the Gulf will interact with a developing Plains storm system early in the period, increasing southeast winds Thursday night through Friday and supporting small craft advisory conditions. A cold front will move near the Lower Texas Coast on Friday but may pull up stationary along the Texas Coastal Bend Friday night into Saturday, weakening the pressure gradient and resulting in decreased wind. The front will likely retreat north Sunday resulting in the return of moderate southeast winds. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...High Rip Current Risk through Thursday morning for TXZ451-454- 455. GM...Small Craft Advisory until 6am CDT early this morning for GMZ150-155. Small Craft Advisory until 4pm CDT this afternoon for GMZ170- 175. |
