Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0106 AM CDT Thu Apr 06 2017

Valid 061200Z - 071200Z

...Synopsis...
A powerful mid-level jet will overspread the southeast today around
the base of a vigorous mid-level low centered over Ohio that will
move northeastward to New York.  At the surface, a low over Ohio
will deepen to 984 mb while moving northeastward toward the
Adirondacks late in the forecast period.  A trailing cold front will
migrate into the western Atlantic during the period while making
steady southeastward progress across the Florida Peninsula and Gulf
of Mexico.  High pressure will build into these areas behind the
front, spreading a dry, mild airmass over much of the southeast and
combining with areas of dry fuels in Florida to result in an
elevated fire weather threat there.  Elsewhere, weak surface flow
will limit the fire weather threat in portions of the southwest and
the southern Rockies.

...Portions of the Southeast...
West-northwesterly surface flow behind a cold front will usher a
mild, dry airmass over much of the region during the afternoon. 
This front should exit the southern Florida Peninsula by
mid-afternoon, with 30-40% minimum RH values filtering into the
region.  Fuels are driest in portions of the Florida Peninsula, and
these fuels, combined with 10-15 mph surface winds, will foster an
elevated fire weather threat this afternoon.  

Across the remainder of the Gulf Coast region (from southern
Louisiana eastward to north Florida), the presence of 15 mph
westerly surface flow and 25-40% RH will foster elevated atmospheric
fire weather conditions where fuels are dry.  However, the abundance
of precipitation that has fallen in portions of these areas
precludes inclusion of fire weather highlights for this outlook.
