UPDATED AVIATION DISCUSSION AND PDT WATCHES/WARNINGS/ADVISORIES

.UPDATE...RADAR INDICATES THAT THE SHOWERS ARE DECREASING IN
COVERAGE OVER THE EAST SLOPES OF THE CASCADES...THE BLUE
MOUNTAINS...AND NORTHEAST OREGON. THIS TREND HAS BEEN CONFIRMED BY
SPOTTERS AND METAR OBSERVATIONS. BOTH NAM AND GFS HAVE DECREASING
VORTICITY ADVECTION AND OMEGA IN NORTHWEST TO WEST FLOW.
HOWEVER...UPSLOPE INTO THE BLUES AND SLOPOVER SHOWERS IN THE
CASCADES WILL KEEP AT LEAST SCATTERED SNOW SHOWERS. NAM HAS THE
HIGHEST QPF IN THE BLUES WITH NORTHWEST UPSLOPE FLOW. WILL MONITOR
SATELLITE AND RADAR TRENDS AND DECIDE WHETHER OR NOT TO EXTEND
WARNINGS. WATER VAPOR SATELLITE STILL SHOWS MORE MOISTURE MOVING
THROUGH EASTERN WASHINGTON AND NORTHEAST OREGON...SO NOT SURE IF
WARNINGS SHOULD BE ALLOWED TO EXPIRE OVER EAST SLOPES OF CASCADES
AND BLUE MOUNTAINS. FEEL CONFIDENT THAT WARNINGS IN NORTH CENTRAL

SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT...SIGNIFICANT SNOW
ACCUMULATIONS HAVE ALREADY OCCURRED ALONG THE EAST SLOPES OF THE
CASCADES AND IN THE NORTHERN AND NORTHWEST BLUE MOUNTAINS. SNOW WILL
CONTINUE TO FALL IN THESE AREAS THROUGH THIS EVENING...ALTHOUGH THE
HEAVIEST PRECIPITATION IS EXPECTED TO SUBSIDE THIS AFTERNOON AS THE
COLD FRONT PASSES THROUGH THE AREA. WINDS ARE ALSO EXPECTED TO
SUBSIDE LATER TONIGHT...THOUGH REMAIN BREEZY. ELSEWHERE...SCATTERED
RAIN AND SHOWERS ARE POSSIBLE THROUGHOUT THE NIGHT.

A RELATIVE BREAK IN ACTIVE WEATHER IS EXPECTED ON FRIDAY AS DRIER
AIR AND HIGHER PRESSURE MOVE INTO THE REGION. HOWEVER...MOIST
PACIFIC ONSHORE FLOW WILL ALLOW FOR SCATTERED SNOW SHOWERS IN THE
FAVORED UPSLOPE FLOW AREAS OF THE CASCADES AND THE MOUNTAINS OF
EASTERN OREGON AND SOUTHEAST WASHINGTON. TEMPERATURES WILL REMAIN
MILD IN THE 30S AND 40S.  CALDER

FREEZING OR BELOW TEMPORARILY AND SOME SLIGHT ACCUMULATION IS
POSSIBLE OVERNIGHT. THE LOW DRIFTS SLOWLY ACROSS THE AREA SUNDAY
KEEPING US IN SHOWERS BEFORE DRIER AIR TRIES TO WORK ITS WAY INTO
THE REGION FROM THE WEST SUNDAY NIGHT. THIS BRIEF BREAK IN BETWEEN
SYSTEM WILL GIVE WAY TO YET ANOTHER STORM SYSTEM THAT IS EXPECTED
TO AFFECT THE AREA MONDAY WITH MORE SHOWERS.

MONDAY NIGHT THROUGH THURSDAY...THE UPPER LEVEL FLOW WILL REMAIN
NORTHWESTERLY THROUGH THE PERIOD. DISTURBANCES WITHIN THIS FLOW WILL
KEEP SOME CHANCE OF PRECIPITATION GOING THROUGH THE PERIOD FOR MOST
