SPECIAL WEATHER STATEMENT

Expiration: 145 PM PST THU DEC 03 2009
...LIGHT LOW ELEVATION SNOW OR FLURRIES ARE POSSIBLE OVER
SOUTHWEST WASHINGTON AND NORTHWEST OREGON OVER THE WEEKEND...
THE FIRST SNOW TO LOW ELEVATIONS IN SOUTHWEST WASHINGTON AND
NORTHWEST OREGON IS POSSIBLE OVER THE WEEKEND.
A COLD WEATHER PATTERN IS SETTING UP FOR THIS WEEKEND AND EARLY
NEXT WEEK. THE FIRST COLD FRONT IS EXPECTED TO MOVE DOWN FROM BRITISH
COLUMBIA AND ACROSS WASHINGTON AND OREGON FRIDAY NIGHT. THIS
SYSTEM WILL NOT CONTAIN MUCH MOISTURE BUT WITH COLD DRY AIR IN
PLACE OVER THE AREA SOME LOW LEVEL SNOW FLURRIES ARE POSSIBLE IN
THE NORTHERN VALLEYS WITH A SLIGHT CHANCE OF MEASURABLE SNOW IN
THE CASCADES.
A SECOND SYSTEM WILL MOVE DOWN FROM THE NORTH SATURDAY NIGHT AND
SUNDAY. MUCH COLDER AIR WILL ACCOMPANY THIS SYSTEM AS IT PUSHES AN
ARCTIC FRONT SOUTH ACROSS WASHINGTON AND INTO OREGON. LOW
ELEVATION SNOW FLURRIES OR SHOWERS ARE POSSIBLE WITH THIS SYSTEM
BUT THE SHOWERS COULD ALSO MISS MUCH OF THE AREA.
THERE IS A CHANCE FOR MORE SUBSTANTIAL MOISTURE TO IMPACT OUR
AREA AROUND THE MIDDLE OF NEXT WEEK. SHOULD THE COLD AIR REMAIN IN
PLACE AS THE MOISTURE ARRIVES...PRECIPITATION WOULD BE IN THE FORM
OF SNOW. AT THIS TIME DETAILS ARE STILL VERY UNCERTAIN.
