210 PM PST TUE MAR 29 2005

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT. CHALLENGE WILL BE WITH
WINDS FOR TONIGHT AND RAIN/SNOW CHANCES.

LOW PRESSURE TRACKING TO THE NORTH WAS TIGHTENING PRESSURE GRADIENTS
ACROSS THE AREA TO MAKE FOR A VERY WINDY DAY. MOST LOCATIONS ACROSS
THE TWO STATE AREA WERE REPORTING SUSTAINED WINDS BETWEEN 25 TO 35
MPH WITH GUSTS TO 45 MPH. 850MBS/WINDS WERE AROUND 40KTS AFTER
SUNSET AND WILL LET THE WIND ADVISORY CONTINUE INTO THIS EVENING.
PSC HAD SOME BLOWING DUST BUT WITH RECENT RAINS FEEL THIS SHOULD NOT
REACH BLDU ADVISORY CRITERIA. CHALLENGE WILL BE WITH PCPN TONIGHT.
WITH AN UPSLOPE FLOW OVER THE BLUES/WALLOWAS AND CREST OF THE
CASCADES...WILL PROBABLY GO WITH LIKELY POPS FOR TONIGHT WITH SOME
POSSIBLE ACCUMULATIONS. PARTIAL CLEARING OCCURS TOMORROW AS A WEAK
RIDGE MOVES OVER THE AREA. LOCATIONS THAT HAVE LIMITED CLOUD
COVER TOMORROW NIGHT...OVERNIGHT LOWS SHOULD FALL BELOW FREEZING.
BEHIND THE RIDGE...ANOTHER DISTURBANCE APPROACHES THE PACNW
THURSDAY. MOISTURE SHOULD SPILL INTO THE WESTERN PORTIONS OF THE
AREA THURSDAY AFTERNOON AND THEN THE REMAINDER OF THE REGION AT
NIGHT.

TEMPERATURES SHOULD BE NEAR NORMAL WEDNESDAY. THEN WARMER AIR
ADVECTS/MOVES INTO THE REGION THURSDAY WITH INCREASING SNOW LEVELS
EXPECTED ALONG WITH ABOVE NORMAL AFTERNOON HIGHS THURSDAY.

&&

.LONG TERM...FRIDAY THROUGH TUESDAY...FAIRLY ACTIVE WEATHER PATTERN
TO PERSIST IN THE EXTENDED PERIOD. AN UPPER LEVEL STORM SYSTEM AND
ASSOCIATED COLD FRONT WILL MOVE ACROSS THE REGION FRIDAY AND FRIDAY
NIGHT WITH A CHANCE OF SHOWERS. A STRONGER SYSTEM WILL MOVE ACROSS
WASHINGTON AND OREGON SUNDAY INTO MONDAY WITH A BETTER CHANCE FOR
RAIN. COULD EVEN BE SOME THUNDERSTORMS WITH THIS SYSTEM BUT MUCH TOO
FAR IN THE FUTURE TO INCLUDE IN THE FORECAST AT THE PRESENT TIME.
RIDGE IS FORECAST TO BUILD OVER THE PACIFIC NW EARLY NEXT WEEK BUT
IN SPITE OF THIS FACT THE LATEST GFS IS INDICATING SOME WARM
ADVECTION TYPE PRECIPITATION OVER WESTERN AND NORTHERN SECTIONS OF
THE FORECAST AREA ON TUESDAY. TEMPERATURES WILL BE CLOSE TO NORMAL
THROUGH THE PERIOD...BUT COULD BEGIN TO NUDGE ON THE WARM SIDE NEXT
WEEK IF THE LATEST GFS IS ON TRACK. 78
