VALID 061200Z - 071200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE GREAT BASIN INTO
THE CENTRAL ROCKIES...
..SYNOPSIS
BROAD MIDLEVEL TROUGHING WILL PERSIST ACROSS THE NORTHWESTERN CONUS,
WHILE AN EXPANSIVE MID/UPPER-LEVEL ANTICYCLONE REMAINS CENTERED ON
THE SOUTHWEST/SOUTHERN ROCKIES.
..GREAT BASIN INTO THE CENTRAL ROCKIES
BETWEEN THE MIDLEVEL TROUGHING AND EXPANSIVE MID/UPPER-LEVEL
ANTICYCLONE, A BELT OF ENHANCED DEEP-LAYER WEST-SOUTHWESTERLY FLOW
WILL REMAIN IN PLACE ACROSS THE GREAT BASIN INTO THE CENTRAL
ROCKIES. A DIURNALLY DEEPENING PBL WILL EXTENT INTO THIS ENHANCED
FLOW ALOFT, YIELDING AN EXPANSIVE OVERLAP OF AROUND 20 MPH SUSTAINED
WEST-SOUTHWESTERLY SURFACE WINDS AND 10-15 PERCENT RH. THESE
CONDITIONS, COMBINED WITH HIGHLY RECEPTIVE FUELS, WILL FAVOR ANOTHER
DAY OF CRITICAL FIRE-WEATHER CONDITIONS ACROSS THE REGION.
..DRY THUNDERSTORMS - SOUTHWEST INTO THE CENTRAL ROCKIES
BOUNDARY-LAYER MIXING BENEATH A PLUME OF WELL-ESTABLISHED MIDLEVEL
MOISTURE EXTENDING FROM THE SOUTHWEST INTO THE CENTRAL ROCKIES WILL
YIELD SUFFICIENT INSTABILITY (CHARACTERIZED BY INVERTED-V SOUNDINGS)
FOR ISOLATED TO WIDELY SCATTERED THUNDERSTORM DEVELOPMENT --
GENERALLY FOCUSED ALONG TERRAIN FEATURES. PW VALUES OF 0.50 TO 0.75
INCHES WILL PROMOTE MOSTLY DRY THUNDERSTORMS, WHICH WILL POSE A RISK
OF LIGHTNING-INDUCED IGNITIONS AND STRONG OUTFLOW WINDS.
