While drought conditions improved following heavy rains in late March across all of the Rio Grande Valley/Deep South Texas ranchlands, Severe (D2) Drought conditions remained across northwestern Starr, much of Jim Hogg and all of Zapata County where the heaviest rains in late March did not fall. Little to no rain fell in these areas in April.

The episode as NWS BRO wrote it up.
While drought conditions improved following heavy rains in late March across all of the Rio Grande Valley/Deep South Texas ranchlands, Severe (D2) Drought conditions remained across northwestern Starr, much of Jim Hogg and all of Zapata County where the heaviest rains in late March did not fall. Little to no rain fell in these areas in April. Though the month is among the driest on the calendar, modest temperatures and increased humidity during the second half of the month held Severe conditions through the entire month of April.
Agricultural impacts (mainly cattle herd culling) were unknown in these areas.

Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1224 AM CDT Tue Apr 1 2025 ...New AVIATION... .SHORT TERM... (Tonight through Tuesday night) Issued at 230 PM CDT Mon Mar 31 2025 Key Messages: - Warm and humid conditions will lead to a minor to moderate heat risk across Deep South Texas. - Patchy to areas of fog across portions of the region and over the Gulf waters tonight. Light north to northeast winds in wake of the passage of a weak frontal boundary this afternoon will gradually return back to the east and southeast tonight, generally remaining at speeds near or less than 5-10 MPH. Low clouds and fog will likely develop along and east of US-281 and over the Gulf waters. Probabilistic guidance, including the HREF, indicate the best potential for visibility below 1 mile will be over the Gulf waters and along the Lower Texas beaches, but we'll continue to assess trends over the next few hours for any changes. Otherwise, a mild night with low temperatures in the 70s is expected region wide. Morning cloud cover and fog will clear by mid to late morning on Tuesday as southeast winds increase in speed due to a tightening pressure gradient. Afternoon high temperatures will warm into the upper 70s and low 80s along the immediate coast to low 90s across the Rio Grande Plains. In combination with the humidity, a minor to moderate heat risk is expected across the region tomorrow afternoon. Remember to take frequent breaks in the shade and stay hydrated if spending time or working outdoors. Wind speeds around 15-20 MPH with gusts of 25-35 MPH will prevail Tuesday afternoon through Tuesday night. Low temperatures will once again fall into the 70s region wide Tuesday night. && .LONG TERM... (Wednesday through next Monday) Issued at 230 PM CDT Mon Mar 31 2025 A mid level trough will dig into the western US and move into the Four Corners by Thursday before pushing into the Plains this weekend. Surface low pressure developing over the High Plains and into the Sierra Madre will enhance the pressure gradient across Deep South Texas through much of the week. The addition of a developing strong low level jet across portions of the Valley and along the coast will lead to breezy to windy conditions into Saturday morning. Most notably, Wednesday morning the LLJ across the Valley and along the coast looks to be quite potent at 55-60 kts. Will continue to monitor for the potential of these strong winds wind mixing down to the surface and the need for Wind Advisories. The aforementioned trough will eventually push a cold font through Deep South Texas late Saturday. This will bring a chance for rainfall Saturday night into Sunday. Currently precip chances remain near or less than 20%, and this would be mainly along the coast. Breezy northerly winds are expected once again in wake of the front on Sunday. Temperatures will remain above normal through Saturday. On Wednesday and Thursday, high temperatures and humidity will lead to "feels like" temperatures hitting the low triple digits in the mid Valley and into eastern portions of the Ranchlands. With the cold front moving through Saturday evening, cooler temperatures are expected Sunday and Monday, with temperatures around 10 degrees below normal. && .AVIATION... (06Z TAFS) Issued at 1221 AM CDT Tue Apr 1 2025 MVFR conditions are currently being experienced at all airports. TAFs are expected to remain MVFR and possibly raise to VFR particularly for MFE by 17z. Winds are expected to be gusty and southeasterly, with gusts picking up around 15-16z. Though confidence is not high enough to include in the TAF package, there could also be some LLWS concerns between 05z and 14z as a low level jet begins to set up overnight. && .MARINE... Issued at 230 PM CDT Mon Mar 31 2025 Tonight through Tuesday night...Generally light winds and low to moderate seas will prevail through mid morning tomorrow. Winds will increase in response to a tightening pressure gradient through the remainder of the period and result in increasing seas. Small Craft Exercise Caution conditions will prevail by tomorrow afternoon and evening, and a Small Craft Advisory may be needed late Tuesday night. Otherwise, marine fog with visibility around 1-3 miles will continue through the evening, and may fall below 1 mile tonight and require the issuance of a Marine Dense Fog Advisory tonight into early tomorrow morning. Patchy marine fog may continue through the day as well. Wednesday through Sunday...Low pressure moving into the Plains and across northeastern Mexico will lead to an enhanced pressure gradient across the lower Texas coast. Small Craft Advisories will be likely through much of the period. && .PRELIMINARY POINT TEMPS/POPS...
