Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0114 AM CDT Tue May 10 2022

Valid 101200Z - 111200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHWEST...

...Synopsis...
A blocked upper flow regime will prevail across the CONUS today,
with a broad upper trough meandering across the western/central U.S.
as a mid-level low remains stationary off of the Atlantic Coast.
While a broad swath of low-level moisture will usher northward
across the Plains due to lee troughing, dry and windy conditions are
expected to develop across portions of the Southwest and along the
East Coast, promoting fire weather concerns.

...Southwest...
Strong, deep-layer southerly flow will persist across the Southwest
as an upper trough and associated surface low meanders around the
Four Corners region today. At the surface, dry and windy conditions
are expected across the Southwest through the afternoon, promoting
Critical wildfire-spread potential. Elevated highlights have been
introduced for areas that should see 15+ mph sustained
south-southwesterly surface winds coinciding with 15-20 percent RH
through the afternoon, and where fuels are at least modestly
receptive to wildfire spread. Critical highlights have also been
introduced where 20+ mph winds and RH below 15 percent will overlap
with critically dry fuels through the afternoon.

...New England...
Dry northeasterly surface winds up to 15 mph will spread across
parts of New England given the presence of a cyclone situated off of
the Atlantic coastline. By afternoon peak heating, surface RH will
drop below 30 percent over portions of southern New Hampshire into
Massachusetts and Connecticut. Fuel guidance suggests that fuels
have recently beco*e quite receptive to wildfire spread, with
Elevated highlights introduced for areas where the aforementioned
overlapping surface winds/RH will occur, and where rainfall
accumulations have remained at/under 0.50 inches in the past 2
weeks.

...Southeast...
Surface high pressure and associated dry northerly flow will prevail
across southern Georgia into the Florida Panhandle and central
Florida Peninsula this afternoon. Guidance consensus shows RH
dipping into the 20-35 percent range by afternoon peak heating,
where the latest forecast fuel guidance shows ERCs in the 80-95th
percentile range. However, surface winds are expected to be weak
overall (barely reaching 10 mph in several locales), hence the
withholding of fire weather highlights. Nonetheless, at least
localized wildfire-spread concerns will exist wherever gusty winds
may develop.
