Area Forecast Discussion ...UPDATED National Weather Service Brownsville TX 1249pm CDT Wednesday Mar 26 2025 Long Term (Friday through next Wednesday) Issued at 631am CDT Wednesday Mar 26 2025 - Heavy rainfall through Thursday night. The ongoing heavy rain event discussed in the short-term may continue for at least on more period as the mid to upper level trough supporting the influx of abundant deep moisture is shown by the 00Z model suite remaining over Texas with its axis still along the Rio Grande. 30+kts mid-level Southerly flow continue to surge rich moisture over a stationary front, straddling the CRP/BRO County Warning Areas. This set up to combine with modest instability (high dew points), lift over the frontal boundary and steep mid-level lapse rates continuing to allow for additional developing convective clusters which may produce another round of heavy rainfall and/or severe convection (hail gusty wind) mostly Thursday evening and overnight. Some lingering rain Friday morning before improving conditions spread west to east as the mid/upper trough axis tracks east of Texas. The weekend looks fair and warm to hot as shortwave ridge tracks over the state. Next front approaches Monday before pulling up stationary Tuesday and lifting north Wednesday. Moisture will be limited with this front with only a slight 10-15 percent chance of rain early next week. Temperatures look to start off near to potentially a few degrees below normal Thursday night and Friday with rain cooled air and limited insolation. Maximum Temperatures warm-up above normal (4-10 degree) for the weekend before dropping back down to seasonal averages with the next front early next week. Minimums remain above normal over the weekend and the beginning of next week as winds remain southerly with no cold front passage. Marine Issued at 631am CDT Wednesday Mar 26 2025 Today through Thursday...While marine conditions are expected to be generally favorable for today, the same can not be said for tonight and Thursday. Winds and seas are expected to become more elevated with southeasterly winds increasing to around 15 to 18 knots and seas between 4 to 6 feet, thus Small Craft Exercise Caution conditions are likely for tonight and Thursday. However, a low end Small Craft Advisory cannot be ruled out. In addition to the winds and seas, showers and thunderstorms are also expected and can produce heavy downpours reducing visibility and locally elevated winds and seas tonight and Thursday. Thursday night through Wednesday Adverse marine conditions may be ongoing Thursday night and Friday as showers and thunderstorms are likely to be widespread producing gusty winds and rough seas. The widespread thunderstorms, moderate to strong winds and hazardous seas through Friday are due in part of a slow moving mid-level low pressure trough over Texas, a stationary front over the Western Gulf combining with modest high pressure noted over the Eastern Gulf. Once the trough passes to the east Saturday high pressure builds over the Texas coast with a steady improvement of marine conditions with fair conditions Sunday through Tuesday. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...Flood Watch from 7pm CDT this evening through Friday morning for TXZ248>251-351-451. GM...None. |
