VALID 181200Z - 191200Z
ACCELERATING MID-LEVEL WESTERLY FLOW IN ADVANCE OF AN UPPER-LEVEL
SHORT WAVE WILL SUPPORT BREEZY DOWNSLOPE FLOW ACROSS THE COLUMBIA
BASIN. DESPITE A SLIGHT INTRUSION OF PACIFIC MOISTURE, DAYTIME
RELATIVE HUMIDITY SHOULD STILL FALL INTO THE 20-25 PERCENT RANGE.
COUPLED WITH BREEZY WEST WINDS AND DRY FUELS, ELEVATED HIGHLIGHTS
WERE MAINTAINED FOR THE COLUMBIA BASIN WHERE DRY FUELS WILL SUPPORT
FIRE SPREAD.

..SYNOPSIS
PRECEDING A DEEP MIDLEVEL LOW WEST OF BRITISH COLUMBIA, A BELT OF
STRONG MIDLEVEL WESTERLY FLOW WILL OVERSPREAD THE CASCADES. AS A
RESULT, LOCALLY DRY/BREEZY DOWNSLOPE FLOW WILL DEVELOP IN THE
COLUMBIA BASIN DURING THE AFTERNOON. AROUND 15 MPH SUSTAINED
WESTERLY SURFACE WINDS (HIGHER IN THE CASCADE GAPS) AND 20-25
PERCENT RH WILL FAVOR ELEVATED FIRE-WEATHER CONDITIONS.
