.DISCUSSION...
Issued at 1214 PM CDT Thu Mar 19 2026

High pressure dominates Deep South Texas into late next week,
with temperatures once again warming above normal and no chance of
rain. Breezy southeasterly winds each afternoon may help maintain
relative humidity values above any fire weather criteria along
and east of US281/I69C. Relative humidity values to the west
across the brush country will drop below 20-30 percent each
afternoon, but do so without the breeze, until the evening, when
moisture is recovering, potentially limiting additional fire
weather concerns at this time.

The entire region remains primed for wildfires and burn bans are
in effect across all of Deep South Texas, except Kenedy County.
CPC is leaning toward above normal rainfall occurring during the
final week of March at 40-50 percent probability.

Issued at 1214 PM CDT Thu Mar 19 2026

the bay may occasionally kick up a moderate chop or brief Small
Craft Caution gusts.
