Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0211 AM CDT Thu Apr 28 2022

Valid 281200Z - 291200Z

...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE SOUTHWEST AND THE
SOUTHERN HIGH PLAINS...

...Synopsis...
A midlevel trough acco*panied by enhanced west-southwesterly flow
aloft will overspread the Intermountain West and impinge on the
central and southern Rockies. Meanwhile, a lee surface low will
deepen over eastern CO, with a dryline extending southward over the
southern High Plains. Farther east, strong northwesterly flow on the
backside of an occluded mid/upper-level low will persist over the
Northeast and Mid-Atlantic states, where a dry post-frontal airmass
will remain in place.

...Southwest into the Southern High Plains...
As the enhanced west-southwesterly flow overspreads a dry antecedent
airmass across the Southwest and southern High Plains, diurnal
heating/mixing will result in widespread 5-15 percent RH behind the
dryline. Sustained west-southwesterly surface winds near 20-25 mph
will develop amid the critically low RH during the afternoon. The
best overlap of the strong surface winds and dry boundary-layer
conditions is expected across portions of east-central AZ, NM, and
far west TX -- where Critical highlights have been maintained.

...Northeast and Mid-Atlantic...
Breezy northwesterly surface winds near 15 mph are expected amid
20-25 percent RH by peak heating. With continued drying of fine
fuels across the region, elevated fire-weather conditions can be
expected over parts of eastern PA, NJ, and far southeastern NY.
