Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0210 AM CDT Wed Apr 20 2022
Valid 201200Z - 211200Z
...CRITICAL FIRE WEATHER AREA FOR MUCH OF NEW MEXICO INTO FAR WEST
TEXAS...
...CRITICAL FIRE WEATHER AREA FOR FAR SOUTHEAST WYOMING INTO THE
NEBRASKA PANHANDLE...
...Synopsis...
Broad/enhanced westerly flow will continue over the western
two-thirds of the CONUS, while a lee surface low develops over far
northeastern New Mexico. The strongest westerly flow will be
confined to the north-central Rockies, within the base of an
eastward-advancing midlevel trough. Farther east, expansive surface
high pressure will move slowly eastward off the Mid-Atlantic coast.
...Southwest into the southern High Plains and Colorado Front
Range...
Another day of warm/dry boundary-layer conditions is forecast across
the Southwest into the southern High Plains and northward along the
Colorado Front Range. Diurnal heating/mixing will encourage
widespread 10-15 percent minimum RH, where breezy westerly surface
winds of 15-25 mph are expected. The strongest surface winds should
develop across much of New Mexico into far West Texas, where
Critical highlights remain in place. Along the Colorado Front Range,
locally critical conditions will be possible primarily across
terrain-favored areas, though the localized nature of these
conditions precludes Critical highlights.
...Central High Plains...
Strong downslope warming/drying and diurnal heating will result in
15-20 percent minimum RH across parts of the central High Plains,
where breezy surface winds will develop. From eastern Wyoming into
the Nebraska Panhandle, 25-30 mph sustained west-northwesterly
surface winds (with gusts upwards of 40 mph) will overspread the
increasingly dry airmass. These meteorological conditions, coupled
with very dry fuels, will result in critical fire-weather
conditions.
...Western Florida Peninsula...
Along the southern periphery of the expansive surface high pressure,
breezy easterly surface winds near 15 mph will overspread the
Florida Peninsula. Over the western portion of the peninsula,
diurnal heating/mixing could result in a narrow corridor of 35-40
percent RH coincident with the breezy surface winds. Elevated
highlights have been introduced to account for this localized
fire-weather threat.
