UPDATED FIRE WEATHER DISCUSSION
.SHORT TERM...TONIGHT THROUGH SATURDAY. UPPER LEVEL LOW MOVING INTO
THE PACIFIC NORTHWEST TODAY AND TONIGHT. STRONG JET AND VORT CENTER
ROTATING THROUGH THE LOW CURRENTLY MOVING ACROSS OUR FORECAST AREA.
SHOWERS AND THUNDERSTORMS HAVE RAPIDLY INCREASED IN COVERAGE. THIS
BAND OF PRECIPITATION WILL CONTINUE TO MOVE NORTHWARD THIS AFTERNOON
INTO THE EVENING. SOME OF THE STORMS COULD BE STRONG FOR THE NEXT
FEW HOURS BASED ON DYNAMICS ALOFT...MAINLY NORTHEAST OREGON AND
SOUTHEAST WASHINGTON. AFTERWARDS LOOKS AS THOUGH PRECIPITATION WILL
BE MAINLY SHOWERS OVER THE CASCADES IN THE ONSHORE FLOW THROUGH THE
NIGHT. AS THE LOW AND FRONTAL BOUNDARY MOVE THROUGH THE REGION
WESTERLY WINDS ARE INCREASING WITH BREEZY CONDITIONS EXPECTED
THROUGH TONIGHT. THE UPPER LEVEL FLOW BECOMES MORE WESTERLY THURSDAY
AFTERNOON. THIS WILL BRING A DRYING TREND WITH DECREASING CLOUDS

REMAIN OVER THE REGION SATURDAY NIGHT BUT BEGIN TO SHIFT EASTWARD ON
SUNDAY. SOUTHWESTERLY FLOW WILL THEN BE OVER THE AREA AND A
SHORTWAVE DISTURBANCE COULD BRING A FEW SHOWERS OR THUNDERSTORMS TO
CENTRAL OREGON SUNDAY NIGHT IF ENOUGH MID-LEVEL MOISTURE IS
AVAILABLE. SHOWERS AND THUNDERSTORMS WILL THEN BE POSSIBLE OVER THE
EASTERN MOUNTAINS ON MONDAY AS THE WAVE TRAVELS NORTHEAST ACROSS THE
AREA. HOWEVER...AT THIS TIME THERE IS A LOT OF UNCERTAINTY SO HAVE
ONLY INCLUDED A SLIGHT CHANCE IN THE FORECAST. THERE IS ALSO A
SLIGHT CHANCE THAT MONSOONAL MOISTURE WILL MAKE ITS WAY FAR ENOUGH
NORTHWARD ON TUESDAY AND WEDNESDAY FOR YET ANOTHER ROUND OF SHOWERS
AND THUNDERSTORMS OVER CENTRAL OREGON AND THE NORTHEAST MOUNTAINS.
BUT AGAIN...THERE IS A LOT OF UNCERTAINTY. OTHERWISE...WARM AND DRY
