Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0200 AM CDT Tue Apr 19 2022

Valid 201200Z - 211200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHWEST INTO THE
SOUTHERN HIGH PLAINS...
...CRITICAL FIRE WEATHER AREA FOR EASTERN WYOMING INTO WESTERN
NEBRASKA...

...Synopsis...
A belt of strong westerly midlevel flow will cross the northern and
central Rockies, maintaining broad surface lee troughing over the
High Plains. Farther east, a dry continental airmass will remain in
place over the southeastern CONUS. 

...Southwest into the southern High Plains...
Diurnal heating/mixing of a dry airmass will result in widespread
10-15 percent minimum RH, where 20-25 mph sustained westerly surface
winds are expected. These meteorological conditions, co*bined with
increasingly dry fuels, will yield critical fire-weather conditions
primarily over New Mexico. 

...Eastern Wyoming into western Nebraska...
Strong downslope flow co*bined with diurnal heating will favor 15-20
percent RH in the lee of the Rockies over eastern Wyoming into
western Nebraska. At the same time, sustained westerly surface winds
of 25+ mph will overspread highly receptive fuels. Therefore,
Critical highlights are in place where the best overlap of the
strong surface winds and dry boundary-layer conditions are expected.

...Eastern Montana...
Strong west-northwesterly surface winds of 25-35 mph (with higher
gusts) will develop across parts of eastern Montana, where
downsloping could yield 25-35 percent minimum RH. While the latest
guidance suggests that fuels are not receptive to wildfire spread,
trends will need to be monitored. 

...Florida Peninsula...
Breezy easterly surface winds near 15 mph are expected across the
Florida Peninsula. While uncertain, diurnal heating/mixing over the
western portions of the peninsula could result in a small corridor
of 35 percent minimum RH. Confidence in the overlap of the breezy
surface winds and low RH is too low to introduce highlights at this
time, though trends will be monitored.
