Day 2 Fire Weather Outlook

Valid 111200Z - 121200Z

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

...High Plains...
Overall the forecast remains valid with a few minor adjustments. The
eastern edge of the Critical area was trimmed westward away from a
diffuse dryline where high surface moisture is likely to limit the
potential for prolonged critical humidity. Thunderstorm development
is expected near and east of this dryline across portions of eastern
NM later in the afternoon. Model soundings show a mixed wet/dry mode
is likely. While not overly dry, enough storm coverage likely exists
for isolated dry strikes outside of the wettest cores atop very dry
fuels. As such a small area of IsoDryT has been added from eastern
NM and far southwest TX.

...Florida...
Across the western Florida Peninsula, dry northeasterly winds are
expected through much of the afternoon. Hi-res ensemble guidance has
co*e into better agreement on the coverage of 10-15 mph surface
winds across much of the region. While not overly robust, occasional
gusts to near 20 mph, humidity below 30% and abnormally dry fuels
may support a few hours of elevated fire weather potential across
the western Peninsula. A small Elevated area has been added to
account for this.

.PREV DISCUSSION... /ISSUED 0135 AM CDT Tue May 10 2022/

...Synopsis...
Surface-low intensification is expected around the Four Corners as
the upper trough ejects eastward and overspreads the Rockies
tomorrow/Wednesday. 15-25 mph sustained southwesterly surface winds
will coincide with 10-15 percent RH by afternoon as the boundary
layer mixes, promoting at least Elevated conditions for wildfire
spread across the Southwest. Critical highlights have also been
introduced where the strongest winds/lowest RH overlap for several
hours atop critically dry fuels Wednesday afternoon.

Dry northerly flow will continue across the Florida Peninsula
tomorrow as a surface low meanders off of the Atlantic Coast. Latest
guidance consensus shows RH dropping below 30 percent by afternoon
peak heating, with some guidance members showing surface winds
reaching 15 mph at times. Confidence is not quite high enough to
introduce Elevated highlights, given the lack of upper support to
force a stronger low-level wind field. If guidance continues to
depict more widespread 15 mph winds in later guidance, future
outlooks may include Elevated highlights for the western half of the
Florida Peninsula.
