..SYNOPSIS
UPPER-LEVEL RIDGING WILL BEGIN TO TRANSITION TOWARDS THE CENTRAL
U.S. AS EASTERN PACIFIC TROUGHING APPROACHES THE PACIFIC NORTHWEST.
MEANWHILE, TROUGHING WILL PERSIST ACROSS THE EASTERN U.S. WITH
SEVERAL EMBEDDED SHORTWAVES PROVIDING UNSETTLED CONDITIONS IN THE
MIDWEST AND PORTIONS OF THE SOUTHEAST.
ENHANCED SOUTHWESTERLY FLOW WILL OVERSPREAD THE PACIFIC NORTHWEST,
NORTHERN ROCKIES, AND THE MONTANA PLAINS ON DAY 2/FRIDAY, BRINGING
HOT, DRY, AND WINDY CONDITIONS TO A MOSTLY DRY FUELSCAPE. WITH
PRECEDING DAYS OF MIXED WET/DRY THUNDERSTORMS AND ABUNDANT LIGHTNING
BEING FOLLOWED BY SUCH METEOROLOGICAL CONDITIONS, HOLDOVER IGNITIONS
ARE LIKELY TO EMERGE. DAYTIME RH VALUES OF LESS THAN 20% ARE
EXPECTED TO COMBINE WITH SOUTHWEST-WESTERLY SUSTAINED WINDS OF 15-20
MPH, WARRANTING ELEVATED HIGHLIGHTS. WHILE SOME POCKETS OF HEAVIER
RAINFALL FROM PRIOR DAYS THUNDERSTORMS MAY ALLEVIATE LOCALIZED FUEL
CONCERNS, THE EXPANSIVE ENVIRONMENT IS APPROACHING, OR HAS ALREADY
REACHED, CRITICAL FUEL THRESHOLDS. A CRITICAL RISK AREA WAS
INTRODUCED ACROSS NORTHEASTERN CALIFORNIA, NORTHWESTERN NEVADA, AND
SOUTH-CENTRAL/SOUTHEASTERN OREGON WHERE 15-25 MPH SOUTHWESTERLY
WINDS AND LESS THAN 15% RH WILL OVERLAP 80-90TH PERCENTILE ERCS.
CRITICAL WINDS/RH ARE LIKELY TO DEVELOP ACROSS PORTIONS OF
NORTH-CENTRAL AND NORTHEAST MONTANA AS WELL, BUT THESE CONDITIONS
WILL LIKELY ACT AS MORE OF A CURING EVENT.
