...HEAVY SNOW POSSIBLE ACROSS WESTERN WASHINGTON MONDAY NIGHT AND
TUESDAY MORNING...

A WEATHER SYSTEM MOVING ACROSS THE EASTERN PACIFIC IS FORECAST TO
REACH WESTERN WASHINGTON MONDAY NIGHT AND TUESDAY. WHEN THE SYSTEM
GETS TO WESTERN WASHINGTON...IT WILL RUN INTO A VERY COLD AIR MASS
ALREADY IN PLACE OVER THE REGION. THE WARM AIR ASSOCIATED WITH THE
INCOMING SYSTEM WILL OVERRUN THE COLD AIR IN PLACE. THIS COMBINATION
COULD LEAD TO HEAVY SNOW ACROSS WESTERN WASHINGTON MONDAY NIGHT AND
TUESDAY. AT THIS TIME...THIS LOOKS LIKE THE BEST OVERRUNNING SNOW
EVENT FOR WESTERN WASHINGTON SINCE THE HEAVY SNOWS AFTER CHRISTMAS
IN 1996. EVENTUALLY THE WARM AIR WILL SCOUR OUT THE COLD AIR OVER
WESTERN WASHINGTON ON TUESDAY. AT THAT TIME...THE SNOW WILL CHANGE
TO RAIN.

THERE IS STILL SOME UNCERTAINTY CONCERNING THE TIMING OF THE ARRIVAL
OF THIS SYSTEM AND HOW LONG IT WILL TAKE THE WARM AIR TO ELIMINATE
THE COLD AIR OVER THE REGION. BOTH THESE VARIABLES WILL PLAY AN
IMPORTANT ROLE IN THE AMOUNT OF SNOW FALLS ACROSS WESTERN
WASHINGTON.
