Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 1120am CST Thu Jan 23 2025 Long Term (Friday night through Wednesday) Issued at 341am CST Thu Jan 23 2025 Another round of cold temperatures to start out the long term forecast period as the low temperatures for Friday night into Saturday morning will range from upper 30s in the Northern Ranchlands to the mid and upper 40s in the Lower Valley. The chances of freezing temperatures for the Northern Ranchlands based on current model guidance is low, under 30 percent. With winds being generally out of the east to southeast on Friday night, it is possible that the temperatures could be a bit warmer than what is in the forecast currently. During the day on Saturday, the surface winds are expected to become more southerly, which will further enhance the warm air advection over the region. Combine that with the clear to partly cloudy skies over Deep South Texas and the Rio Grande Valley, high temperatures could get back into the upper 70s for Saturday, with the warmer temperatures in the regions with more direct sunshine. Then with similar conditions expected for Sunday, the high temperatures could even get into the lower 80s for some places in the Middle and Lower Valley. Approaching the start of the work week, an upper level trough moves into the Desert Southwest, with the current model guidance showing that it will become a cutoff low and then move slowly into the Central Plains. Should the trough become a cutoff low as the models suggest, then it should remain to the west of the region for a longer period of time and thus a weaker frontal passage remains possible on Monday. This will slightly cool temperatures so that the highs on Monday will be mostly in the upper 60s for the regions with a few places in the Middle and Lower Valley in the lower 70s. Afterwards, the warm temperatures will quickly return to the region on Tuesday and will remain through the rest of the long term forecast period with highs on Wednesday in the mid to upper 70s for most of the region, while the Middle Valley could get into the lower 80s. Marine Issued at 341am CST Thu Jan 23 2025 Today through Friday Buoy 42020 reported west-northwest winds around 4 knots gusting to around 8 knots with seas around 3.9 feet with a period of 10 seconds at 03 CST/9 UTC. The pressure gradient will strenghtens later today and especially into tonight as a surface trough of low pressure continues to develop. Small Craft Should Exercise Caution today and Small Craft Advisories will likely be needed for tonight as winds increase and seas build. There is a medium to high chance of small advisory winds developing after midnight tonight on the Gulf waters. Friday Night through Wednesday....A mixture of Small Craft Exercise Caution and Small Craft Advisory conditions are possible Saturday through Sunday with elevated southerly winds and seas due to an enhanced pressure gradient. However winds and seas are expected to relax by Monday and remain favorable through Wednesday. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...High Rip Current Risk from 6pm CST this evening through Friday afternoon for TXZ451-454-455. GM...None. |
