...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL TEXAS INTO
SOUTHWEST OKLAHOMA...

Portions of central Texas into southwest Oklahoma (along/west of the
I-35 corridor) were upgraded to Critical with this update. Fuels
across this area are becoming increasingly dry (95th+ percentile
ERCs) given the persistent 100 deg afternoon temperatures and lack
of rainfall. While sustained surface winds around 15 mph would
typically be borderline for Critical highlights, frequent 20-25 mph
gusts and the critically dry fuels should generally compensate for
this. 

For additional details on the Day 2 fire-weather risk, see the
previous discussion below.

...Synopsis...
A surface low will continue to deepen across central Kansas on
Thursday which will tighten the pressure gradient across the
southern Plains. Dry and breezy conditions (15 mph sustained winds
and 20 to 30 percent relative humidity) are expected from central
Oklahoma into central Texas with temperatures over 100F. These
meteorological conditions, paired with critically dry fuels which
continue to dry further each day, support an Elevated area across
portions of the southern Plains on Thursday. 

Monsoon moisture will continue to drift west on Thursday, with
isolated thunderstorms amid 0.75 to 1 inch PWAT values across
portions of eastern Oregon, northeast California and northwest
Nevada. These storms will be slow moving, but LCLs will be around
12kft, which will support mostly dry thunderstorms. In addition,
90th to 95th percentile ERCs should be in place across most of this
region on Thursday. Therefore, an IsoDryT delineation is warranted
on Thursday to cover the potential for new lightning starts.
