Day 2 Fire Weather Outlook

Valid 301200Z - 011200Z

...NO CRITICAL AREAS...

Drier northerly flow in the wake of a eastward progressing closed
mid/upper low over the Southwest is expected over portions of the
Great Basin into Utah for D2/Wednesday. However, marginal fuels and
recent precipitation will offset impacts of winds of up to 15 mph
and RH of 15-20%, particularly across Utah. Farther east, above
normal temperatures in the lower 90s, RH reductions down to 20% by
peak boundary layer heating/mixing and exceedingly dry fuels will
align over portions of the Mid-South and Lower Mississippi River
Valley Wednesday afternoon. However, light southerly winds under a
ridge aloft of 15 mph or less should limit a broader fire weather
concern across this region.

...Synopsis...
A ridge of high pressure will transition into the western CONUS,
bringing warmer temperatures and a lighter wind regime to California
and the western Great Basin on Day 2/Wednesday. The center of an
eastward progressing mid-level low will enter New Mexico, gradually
weakening as it becomes reincorporated within broader troughing.
Southerly flow will deepen ahead of the low, providing ample
moisture transport bringing PWAT values above the 95th percentile
across much of the central CONUS into the Upper Midwest. This system
will induce widespread precipitation over an environment stressed by
long-term drought, particularly across portions of the southern
Plains and the New Mexico/Colorado Rocky Mountains. Ahead of the
advancing moisture, a residual hot and dry airmass will remain in
place across the lower Mississippi River Valley where receptive
fuels exist; however, light surface winds should limit fire weather
concerns.
