..SYNOPSIS
WHILE UPPER-LEVEL RIDGING WILL GENERALLY CONTINUE IN THE WEST ON
SATURDAY, SOME BREAKDOWN OF THE RIDGE IS EXPECTED TO OCCUR IN THE
NORTHWEST AS AN UPPER-LEVEL TROUGH PIVOTS INTO THE REGION. THE WEAK
UPPER CYCLONE WILL REMAIN NEAR BAJA. THE OVERALL PATTERN CONTINUES
TO SUGGEST THAT WINDS WILL REMAIN WEAK OVER THE DRIEST FUELS IN THE
SOUTHWEST. RECENT FUEL GUIDANCE SUGGESTS THAT FUELS ARE BECOMING
MARGINALLY DRY IN THE GREAT BASIN/NORTHWEST. THE TIMING OF THE
MID-LEVEL JET WILL BE FAVORABLE DURING AFTERNOON HEATING. WINDS OF
15-20 MPH APPEAR POSSIBLE FROM THE LEE OF THE NORTHERN SIERRA AND IN
THE COLUMBIA BASIN. RH IN NORTHWEST NV/SOUTHEAST OR WILL BE LOWER
(10-15%) THAN IN THE COLUMBIA BASIN (AROUND 20-25%). THE STRONGEST
WINDS IN THE COLUMBIA BASIN MAY BE SLIGHTLY OFFSET FROM THE LOWEST
RH AS SOME MID/UPPER CLOUDS AND MARINE BOUNDARY-LAYER INFLUENCE
APPEAR POSSIBLE. FIRE WEATHER CONDITIONS IN THESE AREAS WILL BE
ELEVATED DURING THE AFTERNOON.
ADDITIONAL THUNDERSTORMS ARE PROBABLE IN AZ/NM AS WELL. HOWEVER,
SOME INCREASE IN PW VALUES, SLOW STORM MOTIONS, AND POTENTIAL
CLUSTERING OF STORMS SUGGEST A LIMITED THREAT FOR DRY LIGHTNING
ACTIVITY.
