This is one of the most ridiculous Advisories I’ve ever seen. “Up to 10 inches” with no lower bound including cities like Covington? Just terrible communication coming out of the NWS right now.

WTF LOL... and it's not even a WSW, just a WWA. For up to 10". Someone make it make sense.

I think my area could do alright this week with a couple periods of snowfall. What an awesome pattern to get one of our latest and greatest snowstorms followed up by some prime powder and foothill show.

Another run showing a roaring SW wind in Seattle on Tuesday afternoon with a really strong c-zone along the King/Snohomish line.

Nice to see it’s been showing a decent CZ over MBY for a few runs now. Would be nice to score some more after the main event!

Honestly starting to get kind of excited the fact that the Euro has shown pepto for me for multiple runs now.

Snow depth on Friday evening... not a great deal for my area.   My area is very exposed to the SW wind.   Places that are protected from the SW wind will do much better at preserving snow cover this week.  

ecmwf-deterministic-washington-snow_depth-7888000 (2).png

Looks like a steady diet of 1-4” snowfall potential here this week.  Should be fun watching it fall.  I sort of like these numerous smaller events.

It doesn't even matter if it was 55 degrees today... road surfaces cool down very quickly when precip and cold air arrives.   If the temp/dewpoint support it then snow will stick to roads no matter what the temperatures were beforehand.  

wetbulb is the key, yep

This is looking like a serious event. The deeper map is after 84 hr period.

Kind of funny how the 1.33km skunks the Snoqualmie valley. Still have a blue dot of 2 inches over me though.

But...but.. how will Tim be able to show us temps will be too high for any meaningful snow this week and models reflecting a slight chance of a death ridge in the long range, huh? HUH??

Death ridge?   😀

And lots of people are posting maps and requesting maps.   I tried to show all aspects of the ECMWF.   I think most people want to know the details.  But if you don't want to know then don't look at the maps.

Seems like the theme for the week. Outside of Monday with a bit more traditional set-up these marginal temp south wind events seem usually only good for conversational snow outside of Clark Co/Forest Grove/Gresham areas.

Agree. 

There is a small window of offshore flow combined with possible deformation ahead of the system on Monday but other than that it looks like S/SW wind marginal snow that won't get the job done for anything widespread or metro wide.

I wouldn’t say you’ve lost credibility. I get what you were going for with the post, obviously some are really going to run with the anti-Government thing though, and it turns into a throwing out the baby with the bath water situation.

Amazing how fast the flow turns to easterly on Sunday evening well into Monday.  As Jim has pointed out... SEA flips from a strong SW wind to below freezing with an east wind in a few hours that night.

I am just giddy about that 90-degree death ridge coming up in mid March!

I really do respect how well you respond when people go after you.  Bravo. 

I bet one of the the new users' first questions when they discover this place is "why do all these people hate on tt-sea so much?"

There should probably be a FAQ on here with the answer. Who is gonna write it?

I demand a map showing 17" of snow for Kingston, and it must be in the short range, none of that phantom long range stuff. If you can't do that, well then, I think we're done here.
