..SYNOPSIS
ALONG THE NORTHWESTERN PERIPHERY OF AN EXPANSIVE UPPER RIDGE OVER
THE WEST, A LOW-AMPLITUDE MIDLEVEL DISTURBANCE AND ACCOMPANYING
INFLUX OF MIDLEVEL MOISTURE WILL OVERSPREAD PARTS OF THE NORTHWEST
TODAY. WHILE THIS SHOULD SUPPORT ISOLATED HIGH-BASED SHOWERS, WEAK
BUOYANCY AND WARM EL TEMPERATURES SHOULD LIMIT THUNDERSTORM
POTENTIAL. WITH THAT SAID, AN ISOLATED STORM OR TWO CANNOT BE
ENTIRELY RULED OUT OVER THE CASCADES IN OR. ELSEWHERE, A LIMITED
OVERLAP OF DRY/WINDY CONDITIONS ATOP RECEPTIVE FUELS WILL REDUCE
FIRE-WEATHER CONCERNS ACROSS THE CONUS.
