Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 627am CDT Thu Mar 30 2023 Long Term (Friday night through Wednesday) Issued at 403am CDT Thu Mar 30 2023 A sharp, positive tilt 500 mb trough will dig south from the Pacific Northwest into the High Plains on Friday. This feature will drive a storm system into the upper Midwest. The models have been reasonably consistent with bringing the tail end of an associated cold front into Texas Friday, stalling and stretching it northeast to southwest over the CWA (County Warning Area) Friday night and Saturday. Moisture with the front appears to be limited but a few showers and thunderstorms could materialize over the upper Valley and Ranchlands Saturday afternoon. 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 low latitude short wave trough will move across the desert Southwest and Texas Saturday night and Sunday with little local effect. Then, another sharp, positive tilt mid-level short wave trough will dig south into the Great Basin area next Monday and Tuesday, generating another storm system over the central to northern High Plains and upper Midwest, and supporting locally breezy southeast return flow. An associated cold front will push south to the CWA on Wednesday, again not having quite enough energy to push all the way through. Rain chances will increase next Wednesday and Thursday as the front stalls over the CWA. We will start to see more and more high temperatures in the 90s during the long term. One exception will be on Saturday when highs will be held down in the 80s with the stalled front in the neighborhood. Temperatures will warm into the 90s with a few century marks Sunday through Tuesday. Again next Wednesday the second front will push into the area, holding high temperatures down in the 90s, and into the 80s on Thursday. Marine Issued at 403am CDT Thu Mar 30 2023 Today through Thursday...Light showers are occurring over the Laguna Madre and nearshore Gulf Waters (0-20nm) due to the presence of a warm front lifting north. Warm air advection has aided in the formation of patchy fog over the Laguna Madre and nearshore waters. Have a Marine Weather Statement in effect until 6am CDT for patchy fog lowering visibilities down to 1 to 3 nm. Offshore seas (20-60nm) have also stayed elevated through the night around 7 to 8 ft. Therefore, extended the Small Craft Advisory out until 1pm CDT for the offshore waters for elevated seas. Though, this SCA (Small Craft Advisory) may need to be extended due to gusty southeasterly winds later today. Friday night through Monday night...Winds will briefly decrease Friday night through Saturday as a cold front hangs up just upstream. Moderate southeast winds and moderate seas will occur again Saturday night through Monday night as return flow becomes reestablished. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...Dense Fog Advisory until 9am CDT this morning for TXZ351-354- 355-451-454-455. High Rip Current Risk until 7am CDT this morning for TXZ451-454- 455. GM...Dense Fog Advisory until 9am CDT this morning for GMZ130-132- 135-150-155.
