**SPECIAL WEATHER STATEMENT: Wind, Rain and…Snow?

I don’t have a whole lot of time to blog this evening, but at 4:30 PM the NWS issued a Special Weather Statement highlighting the potential for a very active day  tomorrow weather-wise. And by active, they mean strong winds to our north (around the Strait of Juan de Fuca) and periods of rain and cold temperatures here in Kitsap.

But what makes this situation interesting is the potential for some wet snow to fall wherever moisture hangs around Friday evening and overnight. Snow levels will drop to 500′ by Friday evening, so any precipitation could become a chunky mix of rain and wet snow, cold rain, or brief snow, but this is a big “IF” situation: “IF we get precipitation heavy enought to allow a bit of snow, IF it’s cold enough by the time the precip gets here, IF you live in a hilly area that would support such snow,” etc. So don’t quote me on this! Just don’t be surprised if you see some chunky splats on your windshield tomorrow evening 😉

Good news is, what appeared to be heavy rain arriving this weekend looks relatively light as most of that would-be moisture takes aim to our north (a common thing during El Nino years). In fact, Saturday looks mostly dry.

Here’s the statement made by the NWS:

SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE SEATTLE WA
430 PM PST THU NOV 12 2009

…ACTIVE WEATHER DAY EXPECTED FRIDAY…

A VIGOROUS COLD FRONT WILL PASS SOUTHEAST ACROSS WESTERN
WASHINGTON FRIDAY MORNING…BRINGING RAIN…MOUNTAIN SNOWS…LOCALLY
WINDY CONDITIONS AND POSSIBLY SNOW SHOWERS TO PARTS OF THE
LOWLANDS.

SOUTH WINDS IN ADVANCE OF THE FRONT WILL INCREASE LATE TONIGHT
INTO EARLY FRIDAY MORNING…MAINLY ALONG THE COAST AND PARTS OF
THE NORTHWEST INTERIOR INCLUDING THE ADMIRALTY INLET REGION. WIND
SPEEDS IN THOSE AREAS ARE EXPECTED TO REACH 20 TO 30 MPH WITH A
FEW GUSTS TO 45 MPH…MAINLY IN AND AROUND THE ISLAND COUNTY AREA.
AFTER THE FRONT PASSES…WINDS WILL BECOME WEST TO SOUTHWEST DOWN
THE STRAIT OF JUAN DE FUCA AND ACROSS THE NORTHWEST INTERIOR
BEFORE DIMINISHING THROUGH THE AFTERNOON. WHILE BELOW WIND
ADVISORY CRITERIA…WIND OF THIS STRENGTH COULD BLOW DOWN A FEW
TREE LIMBS HERE AND THERE WITH ISOLATED POWER OUTAGES.

COLDER AIR WILL SURGE IN BEHIND THE FRONT AND LOWER ALREADY LOW
SNOW LEVELS ACROSS THE REGION. DURING THE MORNING HOURS AHEAD OF
THE FRONT THE SNOW LEVEL WILL BE AROUND 1500 TO 2000 FEET. THE
SNOW LEVEL WILL THEN GRADUALLY DROP THROUGH THE DAY TO AROUND 500
FEET BY EVENING. THIS MEANS SOME OF THE HIGHEST HILLS AROUND THE
REGION COULD SEE A FEW SNOW SHOWERS LATE FRIDAY INTO FRIDAY
EVENING. HOWEVER…OUTSIDE OF THE MOUNTAINS OR THE IMMEDIATE
CASCADE FOOTHILLS…LITTLE TO NO SNOW ACCUMULATION IS EXPECTED.

DRY AND TRANQUIL WEATHER WILL RETURN TO THE REGION LATE FRIDAY
NIGHT INTO SATURDAY.

I’ll blog more about this tomorrow morning…
