..SYNOPSIS
THE UPPER RIDGE OVER THE CENTRAL AND WESTERN US IS FORECAST TO
CONTINUE WEAKENING AS THE UPPER TROUGH DEEPENS OVER THE NORTHERN US
AND ANOTHER MOVES ONSHORE OVER THE WEST COAST. THE INCREASE IN

TEMPERATURES AND DRY WESTERLY FLOW OF 15-20 MPH ARE EXPECTED AHEAD
OF THE UPPER TROUGH. AFTERNOON RH MINIMUMS OF 12-20% ARE ALSO
LIKELY. THIS WILL SUPPORT SEVERAL HOURS OF ELEVATED FIRE-WEATHER
CONDITIONS FROM NORTHEASTERN CA INTO PARTS OF NV AND SOUTHERN OR.
..NORTHERN ROCKIES
ASCENT FROM THE APPROACHING UPPER TROUGH WILL SUPPORT ANOTHER ROUND
OF SHOWERS AND THUNDERSTORMS OVER PARTS OF ID, MT AND NORTHERN WY.
