Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1235 AM CDT Wed Mar 18 2026
New AVIATION
KEY MESSAGES
Updated at 1216 AM CDT Wed Mar 18 2026
Key Messages:
* Warming trend continues through the week.
* Dry conditions expected through the forecast period.
* Ongoing drought and very dry grass/brush mean wildfires can start easily. Use caution with outdoor activities.
DISCUSSION
Issued at 1017 PM CDT Tue Mar 17 2026
Quiet conditions will prevail through the forecast period as high pressure remains in control. A warming trend will continue through the week with 90s returning by Friday.
Dry conditions will continue and humidity levels will rebound into midweek. By the end of the week and through the weekend a drier airmass moves back into the region. Humidity levels fall back into the teens across the Rio Grande Plains to the 30s across the inland coastal counties. While current forecast winds will remain just shy of any fire weather criteria the ongoing drought with critical to extremely dry fuels could lead to rapid wildfire growth if ignited. Will continue to monitor for the potential for Fire Weather products.

MARINE
Issued at 1017 PM CDT Tue Mar 17 2026
