After some spotty but light snow showers on Sunday the cold settled in over the area but the National Weather Service now says that lowland snow is "Possible beginning Tuesday night," and might turn into 2 to 4 inches of snow or "much higher amounts." Expect to see a run on grocery stores, tire places (for those still without snow tires or studs) but the good news is that it is expected to turn to rain for Wednesday morning.

...LOWLAND SNOW POSSIBLE BEGINNING TUESDAY NIGHT...

RAIN AND SNOW SHOWERS THIS EVENING WILL DISSIPATE OVERNIGHT AS A
COOL AND DRY AIR MASS FILTERS INTO WESTERN WASHINGTON FROM THE
NORTH. MOSTLY CLEAR CONDITIONS ARE EXPECTED MONDAY THROUGH TUESDAY WITH HIGHS MAINLY IN THE 30S AND LOWS IN THE 20S.

MOISTURE ASSOCIATED WITH A PACIFIC FRONTAL SYSTEM WILL BEGIN TO
SPREAD INTO WESTERN WASHINGTON TUESDAY NIGHT. AT THIS TIME...

IT APPEARS THE AIR MASS WILL INITIALLY BE COLD ENOUGH SO THAT
PRECIPITATION WILL FALL AS SNOW ACROSS THE LOWLANDS. THE TRACK OF THE ASSOCIATED SURFACE LOW WILL DETERMINE HOW MUCH SNOW FALLS
ACROSS THE AREA BEFORE CHANGING OVER TO RAIN BY WEDNESDAY MORNING.
CURRENT COMPUTER GUIDANCE SUGGESTS AT LEAST 2 TO 4 INCHES OF SNOW
COULD FALL...

BUT MUCH HIGHER AMOUNTS ARE POSSIBLE IF THE SYSTEM
TAKES A MORE SOUTHERN TRACK. CONTINUE TO MONITOR FORECASTS CLOSELY OVER THE NEXT COUPLE DAYS AS THIS STORM SYSTEM DEVELOPS.
