Today's Forecast

Updated Tuesday 5:15 p.m.

So much for that lamb...

March is going out with some of the more active weather we've seen this month (2.20" of rain on March 15 notwithstanding) with a traditional cool, unstable air pattern bringing a dizzying mix of blazing sunshine followed by drenching rains.

Then, of course, anyone from about Seattle to Shoreline went through quite the thunderstorm with a good dose of hail as well.

Showers and thunderstorms will continue this evening, then taper overnight with lows around 40. There is also, believe it or not, some snow in the mountains! (What?) A Winter Weather Advisory is in effect for Stevens Pass for as much as 3-9" of snow overnight. Snoqualmie Pass is expected to get about 1-3".

The air mass remains cool and unstable Wednesday, but not *quite* as unstable as today. Still, expect another mix of showers and sunbreaks, just fewer showers than today and perhaps not quite as intense. Highs will be in the low 50s.

We'll dry out for Thursday amid partly sunny skies (maybe an isolated shower or two) with highs in the mid 50s but another round of steady rains return Friday.

The pattern then repeats for the weekend with a mix of showers and sunbreaks -- perhaps some isolated thunderstorms Saturday but air mass doesn't look as unstable as it was today. Highs will drop to the low-mid 50s.

Showery pattern holds into early next week.

Weather Time lapse video shows how those spooky 'hat' clouds form on Mt. Rainier Time lapse video shows how those spooky 'hat' clouds form on Mt. Rainier (Photo Gallery) (Video)
The sometimes-eerie-looking "Hat" clouds -- officially known as lenticular clouds -- are no stranger to Mt. Rainier. But while to many it might just look like a cloud frozen in time, there is actually quite a bit of air movement involved in making the clouds.

KOMO News photographer Mitch Pittman was up hiking in the Cascades recently and managed to get this amazing time lapse video (above) of a lenticular cloud sitting atop Mt. Rainier. The video is a great illustration of the flow that goes into making the cloud's lens-type feature.
Weather Strange but true: Washington has more tornadoes this year than Midwest states
Scott's Note: The story was true when published on March 23, 2015. There have since been tornadoes in the Midwest as of March 25.

In proof that you can spin statistics in numerous ways, you could truthfully declare that Washington has been one of the most tornado-prone states in the nation this year.

That includes typical tornado alley stalwarts Texas, Oklahoma and Kansas. At least as of March 23, they haven't had any tornadoes reported! They join 43 other states with that distinction.
