...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN TEXAS...

...Synopsis...
A broad mid-level trough will amplify over the eastern CONUS through
the day today, which should result in an expansive surface high
pressure area over the central CONUS. North of a surface cold front,
strong surface flow (20-25 mph) is expected across portions of
southern Texas. In the dry post-frontal air mass, RH is expected to
be in the 15-20% range across the region, and fuels are fairly dry,
so have maintained the Critical fire weather risk in this area.
Surrounding the Critical risk is an Elevated highlight that covers
portions of southeastern Texas and southwest Louisiana, where fuels
are modestly dry due to ongoing drought.

Additionally, the expansive high pressure is expected to tighten the
pressure gradients in southern California, with the LAX-DAG and
LAX-WJF pressure gradients nearing -5 mb during the day on Sunday.
This should induce downslope flow with sustained winds of 15-25 mph
with higher gusts, particularly in wind-prone gaps. With the
downslope drying, RH is expected to be near 15-20%. Fine fuels in
the region should dry with the lowered RH and be receptive to fire
spread, so have maintained an Elevated highlight for fire weather in
the area.
