...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN HIGH
PLAINS....
...Synopsis...
Critical fire weather conditions are expected in portions of the
southern High Plains today.
...Southern High Plains...
A closed mid-level low will move eastward across the southern
Rockies today. Lee cyclogenesis is expected to begin in southeast
Colorado early today before the surface low shifts southeastward
into the Texas Panhandle by evening. As this pressure gradient
tightens, winds are expected to increase to 20 to 30 mph across much
of the southern High Plains. The strongest winds will be from
southeast New Mexico into the western Texas Panhandle and eastern
New Mexico where the pressure gradient will be strongest and where
strong mid-level flow amid deep mixing will transport stronger winds
to the surface. Some breezy southeasterly conditions are expected
across Oklahoma and Kansas, but higher relative humidity and fuel
moisture will mitigate the overall fire weather threat in these
areas.
...North Carolina...
Dry and breezy downslope flow is expected in the lee of the
Appalachians today. The strongest winds of 15 to 20 mph are expected
in North Carolina where relative humidity is also forecast to drop
to 18 to 20 percent. Similar downslope flow scenarios and
Wednesday's observed relative humidity suggests relative humidity
may be even lower than this forecast. However, despite these dry and
breezy conditions expected, fuels are still somewhat moist in the
region. Coordination with local NWS offices suggests another day or
two of drying may be sufficient to support large fire spread, but at
this time, fuels are not supportive and therefore, no elevated
delineation has been added.

Day 2 Fire Weather Outlook

Valid 051200Z - 061200Z
...NO CRITICAL AREAS...
...Synopsis...
...Great Basin into the Northwest...
Some dry and breezy conditions are expected in portions of the
western Great Basin into eastern Oregon on Friday as strong
mid-level flow overspreads the region and the surface pressure
gradient strengthens. However, fuels in this area are still moist
and therefore, no fire weather delineation is warranted.
...Texas...
Breezy conditions are expected in the wake of a cold front across
Texas on Friday, but high relative humidity and cool temperatures
will preclude the fire weather threat for much of this region. There
will be a narrow area near the Rio Grande which may have elevated
fire weather concerns, but this area is too small and conditions are
too marginal at this time for an elevated area to be added.
...Carolinas...
Dry downslope flow is expected on Friday in the Carolinas. Low
relative humidity is expected and fuels will likely be more dry
after dry and breezy conditions on Thursday. However, winds are
currently forecast to be lighter on Friday than Thursday which
precludes fire weather concerns. However, this will be monitored and
if 15+ mph winds appear more likely, an elevated area could be
needed.
