Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1155 AM CDT Sat May 07 2022

Valid 071700Z - 081200Z

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

The previous forecast remains valid with only minor adjustments for
the latest guidance. The Critical area was expanded westward along
the CO Front Range to better capture critical conditions within dry
fuels across the foothills and central Rockies. A slow moving cold
front may limit the temporal extent of the most northern sections of
the Critical area across northeastern CO. However, a few hours of
critical conditions are still expected early this afternoon and
fuels remain quite dry. Elsewhere the forecast remains unchanged,
see the prior discussion for more information.

.PREV DISCUSSION... /ISSUED 0159 AM CDT Sat May 07 2022/

...Synopsis...
The first in a series of active fire weather days is expected to
unfold across the Southwest into the southern High Plains today. A
broad upper trough will gradually amplify across the western CONUS,
and surface low development will occur over the central High Plains
this afternoon. Gradient flow and downward momentum transport
support widespread 20+ mph sustained westerly surface winds, from
the Nevada/Arizona border into the southern High Plains. 5-15
percent RH will coincide with this strong wind field for several
hours during the afternoon, warranting the introduction of fire
weather highlights. Critical highlights are in place where the
aforementioned surface winds/RH will overlap with critically dry
fuels (i.e. forecast ERCs approaching or exceeding the 90th
percentile).
