..SYNOPSIS
AS AN UPPER-LEVEL TROUGH APPROACHES THE PACIFIC NORTHWEST COAST
TODAY, A SERIES OF DISTURBANCES CRESTING THE UPPER-LEVEL RIDGE OVER
THE WEST WILL RESULT IN INCREASED FLOW ALOFT FROM THE PACIFIC
NORTHWEST INTO THE NORTHERN PLAINS. GIVEN THE HOT AND DRY AIRMASS IN
PLACE OVER MUCH OF THE REGION, DEEP BOUNDARY-LAYER MIXING WILL
PROMOTE GUSTY SURFACE WINDS RAISING FIRE-WEATHER CONCERNS IN AN
INCREASINGLY FAVORABLE FUELSCAPE.
..NORTHEASTERN CALIFORNIA
NORTHWESTERN
NEVADA...SOUTH-CENTRAL/SOUTHEASTERN OREGON...
VERY HOT AND DRY CONDITIONS WILL RESULT IN MULTIPLE HOURS OF
SINGLE-DIGIT RH VALUES ACROSS THE REGION. WITH ENHANCED
SOUTHWESTERLY FLOW ALOFT BRUSHING THE AREA, DEEP VERTICAL MIXING
WILL RESULT IN WEST-SOUTHWESTERLY SURFACE WINDS APPROACHING 20 MPH.
GIVEN THE DRY FUELS (ERC VALUES EXCEEDING THE 80TH PERCENTILE) AND
RECENT LIGHTNING EVENTS WITH LIMITED RAINFALL, CRITICAL FIRE WEATHER
CONDITIONS ARE LIKELY.
..NORTHERN MONTANA
VERY STRONG WINDS ALOFT AND A DEEP, WELL-MIXED BOUNDARY LAYER WILL
RESULT IN SUSTAINED AFTERNOON WESTERLY SURFACE WINDS APPROACHING 20
MPH IN THE PRESENCE OF RH VALUES DIPPING JUST BELOW 15%. THESE
ELEVATED CONDITIONS WILL CURE THE FUELS FOR THE COMING DAYS.
