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. ..Cook.. 04/06/2017 ...Please see http://ift.tt/2i2um2s for graphic product...Read more
