..SYNOPSIS
ALONG THE NORTHERN PERIPHERY OF A MIDLEVEL RIDGE CENTERED ON THE
FOUR CORNERS REGION, MONSOONAL MOISTURE ATOP A WARM/DRY BOUNDARY
LAYER WILL SUPPORT ISOLATED TO WIDELY SCATTERED HIGH-BASED
THUNDERSTORMS ACROSS THE NORTHWEST -- WITH A FOCUS OVER THE HIGHER
TERRAIN. OVER THE CASCADES, PW VALUES OF 0.70-0.90 INCHES WILL FAVOR
A MIX OF WET/DRY THUNDERSTORMS OVER RECEPTIVE FUELS, POSING A RISK
OF LIGHTNING-INDUCED IGNITIONS AND GUSTY/ERRATIC OUTFLOW WINDS.
THUNDERSTORM POTENTIAL IS MORE UNCERTAIN OVER THE WA CASCADES OWING
TO LIMITED MONSOONAL MOISTURE COMPARED TO AREAS FARTHER SOUTH.
NEVERTHELESS, ANY STORMS THAT DO FORM WILL BE DRY AND POSE A RISK OF
NEW STARTS.
A CONTINUATION OF WET/DRY THUNDERSTORMS ARE ALSO EXPECTED ACROSS
NORTHERN CA, THOUGH RECENT RAINFALL AND 1+ INCH PW CAST UNCERTAINTY
ON OVERALL IGNITION POTENTIAL. FOR CENTRAL ID INTO SOUTHWEST MT,
MIXED WET/DRY THUNDERSTORMS MAY POSE A SHORT-TERM RISK OF
LIGHTNING-INDUCED IGNITIONS; HOWEVER, INCREASING RAINFALL IN THE
COMING DAYS SHOULD LIMIT THE OVERALL RISK.
