...NewARINE... .KEY MESSAGES... Updated at 1017pm CDT Tuesday Mar 17 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.

Issued at 1017pm CDT Tuesday 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.

Issued at 1017pm CDT Tuesday Mar 17 2026

Favorable conditions will continue on the waters off the lower Texas coast through the period. Winds though Friday will remain light to moderate with seas of 2 to 3 feet. Over the weekend, the pressure gradient tightens slightly and small craft caution may be needed primarily on the Laguna Madre and nearshore Gulf waters.
