High wind watch in the future??? HOPE SO!!
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SEATTLE WA 300 PM PST SUN MAR 27 2005
IN FACT...A MUCH STRONGER PAC STORM SYSTEM IS EXPECTED LATE MON NIGHT THRU TUE. THIS SYSTEM PROMISES TO BRING A PERIOD OF GUSTY WINDS AND UPSLOPE SNOW TO THE CASCADES ON TUE. WIND SPEEDS MAY REACH HIGH WIND CRITERIA OVER PARTS OF THE NRN INTERIOR AS HIGH-END GALE FORCE WESTERLIES RUSH THRU THE STRAIT. LATER SHIFTS MAY WANT TO ISSUE A HIGH WIND WATCH FOR THOSE PARTS OF ****SNOHOMISH**** (Whoooo Hoooo)...ISLAND...AND SKAGIT COUNTIES TYPICALLY AFFECTED BY EVENTS SUCH AS THIS. ADDITIONALLY...THE AIR MASS WILL LIKELY BECOME UNSTABLE BEHIND THE CDFNT AND THUS HAVE INCLUDED A MENTION OF THUNDERSTORMS TUE AFTERNOON FOR THOSE ZONES NORMALLY IMPACTED BY THE PSCZ. LATER SHIFTS MAY ALSO WANT TO CONSIDER THE POSSIBILITY OF A WINTER STORM WATCH FOR THE CASCADES TUE. ALAS YET ANOTHER...BUT WEAKER...FRONTAL SYSTEM IS EXPECTED TO BEGIN AFFECTING THE AREA ABOUT MIDWEEK. EXTENDED...NO MAJOR CHANGES TO THE PREVIOUS FORECAST. IT IS POSSIBLE THAT THERE MAY BE A SIGNIFICANT RAINFALL EVENT SHAPING UP FOR THE LATTER PART OF THE WEEK AS A BAROCLINIC BAND STALLS OVER THE AREA.

Viewing tonights GFS....tomorrow and Tuesdsay is looking pretty wet and breezy/windy....especaily Tuesday. During this time, real late monday night into 12z tuesday....a 991MB low looks to come across central Vancouver B.C which should give us some gusty winds at times. Areas that look to be most affected come Tuesday evening is the enterences into the Straight and North interior portions...where surface winds could be gusting from the WNW at 30+ kts. So could possibly see some higher gales out in thoes areas.
Also, could see some scattered T-Storms as in the afternoon, as lifted indices will be near zero and 850MB temps being near -3C with heights of about 1320M. And 500MB winds appear mainly out of the West at 30 to 35kts with gusts to 40kts or more. May also see some ice pellets showers depending on just how active the PSCZ gets, plus some daytime heating by the sun....if we get any sunbreaks. But over all, this system should be a good snow maker for Cascades and Olympics.

Wow Wee! Another rainfall record for Sea - Tac, and once again from a fabulous year! Today's previous record was from 1968. As you all know the winter of 1968 - 69 was awsome!
Who could not be excited by the prospects for the next several days? Possible high wind watches, winter storm warnings, another possible baroclinic band, possible thundershowers and hail. This is a quintessential cold spring type weather pattern like we often saw in the 1950s, 60s and early 70s!
The snowpack in the mountains should be awsome by the end of the week. I am picturing a few feet of nice soft fluffy snow on top of a nice packed layer underneath. What a comeback!

Here's a small snippet from Joe Bastardi's midday column (he's from Accuweather from those who don't know)
The forecast problem is rain and lots of it. I think in the next 12 days, three major systems will dump on the Pacific Northwest and so rain amounts will be well above normal. What I am worried about here is that the models, though wet, may not be wet enough. If one looks at water profiles, we see a large area of temperatures around 1c above normal from near Hawaii all the way to the Pacific Northwest. The big question becomes how much handoff can there be from southern branch to northern branch?

Cold, wet, windy, and gloomy in Covington this morning. Nearly 11:00am and only 44 degrees! 
We have now had 2.7 inches of rain since it all began on Saturday. That puts our monthly total at nearly 4 inches.
There is little doubt that March and April will both end up with above normal rainfall. The snowpack may get close to normal from 4000 feet and above, but it will not have the normal water content because it won't be nearly as packed and settled as normal. At any rate, we are going to be in pretty good shape. If the entire spring is wetter than normal, I would expect we could get by with no problems this summer.
It continues to look like the cold front / trough coming through tonight and tomorrow could be really exciting stuff.
