..SYNOPSIS
A LOW-AMPLITUDE UPPER LEVEL TROUGH WILL PIVOT THROUGH THE NORTHWEST
ON SATURDAY. IN THE LEE OF THE NORTHERN ROCKIES, A SURFACE LOW WILL
DEEPEN IN CENTRAL MONTANA. MID-LEVEL MOISTURE WILL BE PUSHED
SLIGHTLY SOUTHWARD AND EASTWARD BY THE SAGGING UPPER TROUGH IN THE
NORTHWEST. ADDITIONAL THUNDERSTORMS ARE POSSIBLE IN THE PARTS OF THE
CENTRAL/EASTERN GREAT BASIN. HOWEVER, PWAT VALUES AND SLOWER STORM
MOTIONS DO NOT SUGGEST A SIGNIFICANT THREAT FOR NEW IGNITIONS.
..COLUMBIA BASIN AND NORTHERN NEVADA/SOUTHERN IDAHO
ELEVATED FIRE WEATHER CONDITIONS ARE AGAIN EXPECTED IN THE COLUMBIA
BASIN. WITH THE CORE OF THE MID-LEVEL JET PRIMARILY BEING EAST OF
THE REGION BY THE AFTERNOON, THE OVERALL SETUP SHOULD FAVOR SLIGHTLY
LESS STRONG WIND COVERAGE. WINDS OF 15-20 MPH ARE STILL POSSIBLE. RH
MAY BE A TOUCH HIGHER THAN ON FRIDAY WITH AROUND 20% BEING PROBABLE
DURING THE AFTERNOON.
WITH THE TROUGH SAGGING SOUTHWARD AND THE SURFACE LOW DEEPENING, A
ZONE OF 15-20 MPH (LOCALLY HIGHER) WINDS IS POSSIBLE IN PARTS OF THE
NORTHERN GREAT BASIN. RH COULD FALL AS LOW AS 10-15% BY THE
AFTERNOON.
