EASTERN MONTANA AND THE WESTERN DAKOTAS THIS AFTERNOON. FUELS

25-30 MPH WITH RH NEAR 20-25% WILL SUPPORT SEVERAL HOURS OF ELEVATED

..SYNOPSIS
A MID-LEVEL TROUGH WILL DEEPEN ACROSS THE CENTRAL AND EASTERN CONUS
AS A MID-LEVEL RIDGE BUILDS OVER THE WESTERN U.S. TODAY. RICH
LOW-LEVEL MOISTURE WILL OVERSPREAD MOST OF THE CONUS EAST OF THE
ROCKIES, WITH SCATTERED TO WIDESPREAD THUNDERSTORMS EXPECTED,
MITIGATING SIGNIFICANT WILDFIRE-SPREAD CONCERNS OVER MOST LOCALES.
THE ONE EXCEPTION WILL BE OVER PARTS OF THE NORTHERN HIGH PLAINS.
WIDESPREAD 15-25 MPH SUSTAINED NORTHWESTERLY SURFACE WINDS ARE
LIKELY IN A POST-COLD FRONTAL REGIME, WHERE RH MAY DIP INTO THE
15-25 PERCENT RANGE. GIVEN MODESTLY DRY FINE FUELS PRESENT, ELEVATED
HIGHLIGHTS HAVE BEEN MAINTAINED.
ELSEWHERE ACROSS THE DESERT SOUTHWEST INTO THE GREAT BASIN, A DRY
AND MIXED BOUNDARY LAYER SHOULD SUPPORT WIDESPREAD LOWER RH.
HOWEVER, THE LACK OF A STRONGER SURFACE WIND FIELD SUGGESTS THAT
FIRE WEATHER HIGHLIGHTS ARE NOT CURRENTLY WARRANTED.
