..SYNOPSIS
INCREASING SOUTHWEST WINDS ASSOCIATED WITH AN MID/UPPER TROUGH
IMPINGING UPON THE PACIFIC NORTHWEST WILL PROMOTE ELEVATED FIRE
WEATHER CONDITIONS TO NORTHWEST PORTIONS OF THE GREAT BASIN TODAY.
AN UPPER RIDGE OVER THE SOUTH-CENTRAL CONUS WILL MAINTAIN ABOVE
NORMAL TEMPERATURES FOR PORTIONS OF THE SOUTHERN PLAINS AND LOWER MS
RIVER VALLEY BUT LIGHT WINDS AND MARGINAL RH REDUCTIONS WILL LIMIT
FIRE WEATHER CONCERNS OVER THE REGION WHERE MORE RECEPTIVE FUELS
PERSIST.
..NORTHWESTERN GREAT BASIN
A DEEPENING SURFACE TROUGH OVER EASTERN OR/WA IN RESPONSE TO
INCREASING SOUTHWEST FLOW ALOFT IN ADVANCE OF AN UPPER-LEVEL WAVE
WILL BRING GUSTY SOUTHWEST WINDS TO THE NORTHWESTERN GREAT BASIN
TODAY. THE SUSTAINED SOUTHWEST WINDS OF 15-20 MPH COUPLED WITH
AFTERNOON RH REDUCTIONS OF 15-20% (LOCALLY 10%) WILL BRING AN
ELEVATED FIRE WEATHER THREAT TO NORTHEASTERN CA, SOUTHEASTERN OR AND
FAR NORTHWESTERN NV. THESE METEOROLOGICAL CONDITIONS WILL ALIGN WITH
SUFFICIENTLY DRY FUELS FOR SEVERAL HOURS THIS AFTERNOON.
