.PREV DISCUSSION... /ISSUED 0156 AM CDT WED AUG 27 2014/

...SYNOPSIS...
PRIMARY BELT OF WLYS WILL CONTINUE SAGGING SWD ACROSS THE PAC NW AND
NRN ROCKIES...AS AN UPPER TROUGH AMPLIFIES OVER THE GULF OF ALASKA.
AS THIS OCCURS...A LEE SFC TROUGH WILL BECOME ESTABLISHED OVER THE
PAC NW...AND SUPPORT AN INCREASE IN ONSHORE WINDS THROUGH THE
COLUMBIA BASIN ACROSS PARTS OF ORE/WA. ELSEWHERE...A WEAK SRN STREAM
UPPER TROUGH WILL SLOWLY MOVE EWD ACROSS THE SRN/CNTRL PLAINS. DRY
AIR OVER MUCH OF THE WRN CONUS SHOULD RESULT IN REDUCED TSTM
POTENTIAL.

...PARTS OF THE COLUMBIA BASIN OF N-CNTRL ORE AND S-CNTRL WA...
A DEVELOPING LEE SFC TROUGH ACROSS ERN WA WILL FOSTER A MODEST
INCREASE IN LOW-LEVEL ONSHORE WINDS. MODEL FORECAST SOUNDINGS SHOW
SUSTAINED WIND SPEEDS PEAKING AT 15-20 MPH /LOCALLY STRONGER/ DURING
THE AFTERNOON. RH VALUES OF 20-25 PERCENT ARE ALSO LIKELY AS DAYTIME
TEMPERATURES APPROACH 90 F. THESE CONDITIONS WILL SUPPORT AN
ELEVATED FIRE WEATHER THREAT THROUGH PORTIONS OF THE COLUMBIA BASIN.
