..SYNOPSIS
UPPER-LEVEL TROUGHING WILL PERSIST OVER THE NORTHEASTERN CONUS ON
DAY 2/THURSDAY, WITH AN EMBEDDED MID-LEVEL SHORTWAVE YIELDING
INCREASED PRECIPITATION CHANCES OVER A DROUGHT-STRESSED ENVIRONMENT
IN NORTHERN MINNESOTA AND WISCONSIN. THE ESTABLISHED UPPER RIDGE
OVER THE GREAT BASIN WILL CONTINUE TO AMPLIFY, DELIVERING ABOVE
NORMAL TEMPERATURES AND DRY CONDITIONS TO THE INTERIOR WEST.
MEANWHILE, AN UPPER TROUGH WILL DEEPEN ALONG THE WEST COAST,
USHERING STRONGER SOUTHWESTERLY FLOW INTO THE NORTHWESTERN CONUS.
ACROSS NORTHEASTERN CALIFORNIA, NORTHWESTERN NEVADA, AND SOUTHERN
OREGON, DAYTIME HIGH TEMPERATURES WILL RANGE FROM 90-100 F OR
GREATER AMID 10-20 MPH SUSTAINED WEST-SOUTHWESTERLY WINDS AND RH
VALUES OF 10-15%. THESE METEOROLOGICAL CONDITIONS WILL OVERLAP A
RECEPTIVE FUELSCAPE, PROMOTING AN ELEVATED FIRE WEATHER THREAT. RH
VALUES OF 15-20% AND 10-20 MPH SOUTHWESTERLY WINDS WILL ALSO OVERLAP
PORTIONS OF SOUTHEASTERN NEVADA; HOWEVER, RECENT MONSOONAL MOISTURE
HAS CONTRIBUTED TO LESS RECEPTIVE FUELS, PRECLUDING THE EXPANSION OF
ELEVATED HIGHLIGHTS.
