VALID 051700Z - 061200Z
THE ONGOING FORECAST REMAINS ON TRACK. MODEST TO GOOD OVERNIGHT
HUMIDITY RECOVERIES OCCURRED ACROSS THE REGION, THOUGH MOSTLY CLEAR
SKIES THIS MORNING HAVE RESULTED IN QUICKLY RISING TEMPERATURES AND
DECLINING RH. AS OF 16Z, SURFACE OBSERVATIONS DEPICT RH VALUES HAVE
DECREASED TO NEARLY 15% ACROSS SOUTHEASTERN WY AND CENTRAL MT, AND
LOCALIZED WESTERLY WINDS ARE GUSTING OVER 30 MPH IN TERRAIN-FAVORED
AREAS. AS TEMPERATURES CONTINUE TO RISE INTO THE UPPER 70-80S F
(PERHAPS 90S IN SOME AREAS), DEEP VERTICAL MIXING AND DOWNSLOPE FLOW
WILL PROMOTE RH VALUES AS LOW AS 10% AMID SUSTAINED WESTERLY WINDS
OF 15-20 MPH THIS AFTERNOON, MAINTAINING AN ELEVATED FIRE WEATHER
THREAT.

..SYNOPSIS
ENHANCED WESTERLY WINDS ALOFT WILL OVERSPREAD THE NORTHERN ROCKIES
DURING THIS AFTERNOON. TO THE WEST OF A SURFACE TROUGH IN THE HIGH
PLAINS, WINDS OF 15-20 MPH ARE POSSIBLE FROM CENTRAL MONTANA INTO
WYOMING. LOCALLY STRONGER WINDS ARE POSSIBLE IN TERRAIN-FAVORED
ZONES. DOWNSLOPE FLOW WILL PROMOTE RH OF 10-20%, WITH THE LOWEST
VALUES MORE LIKELY INTO WYOMING WHERE IT WILL BE SLIGHTLY WARMER.
THE STRONGEST WINDS WILL BE IN MONTANA GIVEN THE PROXIMITY TO THE
MID-LEVEL JET. AREAS OF SUFFICIENTLY DRY FUELS SHOULD SUPPORT AT
LEAST POCKETS OF ELEVATED FIRE WEATHER ACROSS THESE REGIONS.
