..SYNOPSIS
A MID/UPPER TROUGH WILL PUSH INTO THE NORTHWEST D2/THURSDAY WHILE A
DEEPENING SURFACE TROUGH AND COLD FRONT EVOLVE OVER THE SOUTHERN
CANADIAN PRAIRIES. DRY AND BREEZY CONDITIONS DEVELOPING IN ADVANCE
OF A COLD FRONT WILL ENHANCE FIRE WEATHER CONCERNS ACROSS PORTIONS
OF THE NORTHERN ROCKIES AND NORTHERN HIGH PLAINS, WHERE FUELS REMAIN
LARGELY RECEPTIVE.
..EASTERN IDAHO, SOUTHERN MONTANA AND PORTIONS OF WYOMING
WEST/NORTHWEST SURFACE FLOW SOUTH OF THE MID-UPPER TROUGH ENTERING
THE NORTHWESTERN CONUS WILL EXPAND AND INCREASE IN MAGNITUDE ACROSS
MUCH OF THE NORTHERN GREAT BASIN INTO SOUTHERN ID, SOUTHERN MT AND
PARTS OF WY BY THURSDAY AFTERNOON. A VERY DRY BOUNDARY LAYER ACROSS
MUCH OF THE INTERMOUNTAIN WEST AND SOUTHWEST WILL PROMOTE RH
REDUCTIONS TO BELOW 10% IN LOWER ELEVATIONS BY PEAK AFTERNOON
HEATING. BROAD WEST/NORTHWEST WINDS OF AROUND 15 MPH COINCIDENT WITH
THE LOW RH DURING THE DAY WILL PROMOTE AN ELEVATED FIRE WEATHER
THREAT PRIMARILY ACROSS EASTERN ID, SOUTHERN MT AND PORTIONS OF WY
WHERE FUELS REMAIN MORE RECEPTIVE. LOCALIZED CRITICAL FIRE WEATHER
CONDITIONS ARE MOST LIKELY ACROSS SOUTH-CENTRAL WY WHERE 20 MPH WEST
WINDS AT TIMES ALIGN WITH SINGLE DIGIT RH. THUS, ELEVATED FIRE
WEATHER HIGHLIGHTS WERE INTRODUCED WITH SOME EXPANSIONS NOTED BASED
ON LATEST MODEL GUIDANCE.
