There are rumors the Hood Canal area could see some sticking snow late tonight through tomorrow. I am doing more research on this potential, but so far this doesn’t look like a major event, and not everyone on the peninsula will be affected, or at least affected the same way.
I will be making a separate post about the snow potential this evening as that is when the details will become more clear. Here’s a Special Weather Statement put out by the National Weather Service early this morning:
NATIONAL WEATHER SERVICE SEATTLE WA
421 AM PST WED FEB 25 2009
…LOCAL SNOW SHOWERS ARE EXPECTED OVER THE WESTERN WASHINGTON
LOWLANDS LATE TONIGHT AND THURSDAY…
A COOLER AIR MASS WILL MOVE INTO WESTERN WASHINGTON
TONIGHT…AND
IT WILL BE COLD ENOUGH FOR SHOWERS TO FALL LOCALLY AS SNOW OR
RAIN AND SNOW MIXED ACROSS THE WESTERN WASHINGTON LOWLANDS LATE
TONIGHT AND THURSDAY.
WIDESPREAD SNOW ACCUMULATIONS ARE NOT EXPECTED…AND HIGH
TEMPERATURES THURSDAY WILL REACH THE LOWER TO MID 40S. HOWEVER
SPOTTY ACCUMULATIONS OF 1 OR 2 INCHES ARE POSSIBLE MAINLY IN
THE
NORTHWEST INTERIOR…ALONG HOOD CANAL…AND IN THE SOUTHWEST
INTERIOR LATE TONIGHT OR THURSDAY MORNING.
I also see one inch for north king south snohomish, do you see the same?
This convergence zone has been in and out of the models, but the latest guidance suggests the normal suspects (north King/south Snohomish) may be too far north and will be shadowed from most of the precip.
But again, there have been large model discrepancies lately and there is still time to work them out. I will give you an update this evening 🙂

P.S. From reading some of your most recent posts, it appears you found the NAM model, but if you would like more sources, click here

Also, if you scroll up, on the right hand side you’ll see something that says “Weather Links”, which are links I recommend. UNYSIS is one of the more popular ones 🙂

I think the Convergence Zone will form well to our North and we will be shadowed from the main precip. I do not expect snow for most of Kitsap. North Kitsap could be an exception, but Central Kitsap/Bainbridge will not see sticking snow IMO. My reasoning is that now the flow is SW so we are shadowed and the CZ is way to our North. Late tonight it switches to NW flow and we are still shadowed and most of the precip is to our South. Kitsap is just the worst spot for snow in this situation.
