.DISCUSSION...
Issued at 1020 PM CDT Wed Mar 25 2026

High pressure holds into late Friday, with well-above normal
temperatures and no chance of rain. A frontal boundary runs south
Friday night into Saturday, briefly dropping temperatures closer
to normal and bringing a low to now medium (25-50 percent) chance
of rain, mainly Saturday morning, dipping south towards the Rio
Grande into Saturday afternoon. Current QPF still sits around 0.15
of an inch or less, mainly across the RGV.

Other than Saturdays brief break, the remainder of the forecast
looks the same Thursday, Friday, and then Sunday into mid next
week. Breezy afternoons and RH values below 30 percent along and
west of US281/I69C. Fire Danger Statements may be issued, but no
Red Flag conditions are expected at this time, with the lowest
moisture being generally west of the stronger winds until the
evening hours, when humidity is recovering.

The entire region remains primed for wildfires and burn bans are
in effect across all of Deep South Texas, except Kenedy County.
CPC precipitation outlooks in both 6 to 10 and 8 to 14 days lean
toward above normal rainfall at 40-50 percent through April 8.
