The previous forecast remains on track with no changes required.
Latest surface observations within the southern CA coastal ranges
show areas of elevated to critical fire weather conditions with
winds gusting between 25-50 mph and RH in the upper teens and low
20s. Such conditions will likely persist through tonight and into
early Sunday morning. Across southern TX, dry conditions are noted
in recent observations with a gradual increase in winds still likely
this afternoon. See the previous discussion below for additional

An upper-level trough will amplify as it moves into the Southeast
today. This will push a cold front through the Plains to near the
Appalachians. Surface high pressure will increase within the Great
Basin and Four Corners regions.

...Southern California...
Offshore winds will likely be maximized early this morning. Winds of
20-25 mph (with higher gusts) will overlap with at least marginally
reduced RH. RH values will fall to near 10-15% in some locations by
the afternoon. Winds will slowly lose some intensity with time, but
should remain 15-20 mph for several hours. Lower elevation fuels
will be the primary driver of fire spread. However, these fine fuels
are only marginally dry at present. Elevated fire weather concerns
are possible where these fuels are driest.

Elevated fire weather is possible within part of the Permian Basin
into the Edwards Plateau. Post-frontal winds will be 15-20 mph amid
15-20% RH. Locally lower RH could occur where a greater downsloping
wind component exists. Fine fuels are marginally dry and will
support a low-end threat for a large fire. Cold advection will tend
to limit the fire weather threat, particularly farther north, as RH
will likely remain above critical thresholds in those areas.
