Add it to the pile: March sets record for all-time warmest in Seattle

Add it to the pile: March sets record for all-time warmest in Seattle

The end-of-the-month blogs these days seem to write themselves, just change the month...

For the fourth time in the past six months, Seattle has set the record for all-time warmest month. March 2015 now joins brethren October, December and February as the warmest on record at Sea-Tac Airport (70 years of data) by average monthly temperature -- found by taking the high and low and divided by two.

This month, the average temperature was 50.5 degrees, just beating 1992's 50.3 degrees. By average high temperature, we came in second place at 57.8 degrees, lagging only behind 1992's 59.1 degrees.

(The readings are behind three others from before Sea-Tac was "born" and records were kept in Downtown Seattle, including a 53.1 average temperature reading in 1941.)

March has featured a bit of extremes, with a mix of sunshine and very warm temperatures for several days, and drenching rains the next. The 2.20 inches of rain that fell on March 15th was the second wettest March day at Sea-Tac. On the other hand, 11 of the 31 days were 60 degrees or warmer, and only three days of the month were considered below normal and none since March 4.

The month also appears to be cementing that Feb. 1 may go down as our last day of the season with a high under 50 degrees which usually that date isn't until well into March, sometimes April.

And March will now make it 13 consecutive months that we've had above normal temperatures.

I've made a short graph to show our amazing warm stretch by average monthly temperature and where the months rank overall in parenthesis -- again this is through 70 years of data):

Seattle (Sea-Tac Airport) Avg. Temp +/- Normal
March 2014 48.5 (11) +2.0
April 52.0 (7) +1.7
May 59.1 (5) +3.1
June 62.0 (21) +1.1
July 69.2 (2) +3.5
August 69.1 (3) +3.0
September 64.8 (2) +3.5
October 58.0 (1) +5.2
November 46.0 (29) +0.6
December 45.3 (1) +4.8
January 2015 45.1 (5) +3.1
February 48.8 (1) +5.4
March 50.5 (1) +4.0


And as the blog I wrote two weeks ago says (and will probably write again in two weeks), the long range forecasts show no stopping to the overall warm weather pattern -- perhaps lasting through the summer.

Time lapse video shows how those spooky 'hat' clouds form on Mt. Rainier

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.

Strange but true: Washington has more tornadoes this year than Midwest states

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.

Say what? Seattle had as many spring days as winter days this past season

As winter comes to a close Friday afternoon at 3:45 p.m., pardon us in Seattle if we hardly notice.

In fact, if it's felt like spring has been around a while, you'd be right, no matter what the calendar tells you.

Surprise!

A bit of a sneaky and severe solar storm hit the planet last night, bringing a show of the Northern Lights in the wee hours of St. Patrick's Day morning.

The photo above was taken by Julia Kelley who went down to Picnic Point Beach last night to catch some fresh air and relax.

How long did the warmth last in past record-warm winters?

How long did the warmth last in past record-warm winters?
Will Seattle ever see snow again in the lowlands? While this warm winter might have you thinking not, all hope is not lost.

The winters of 1976-77 and 1991-92 have been getting a lot of attention of late as they've been the previous standards to which past warm winters have been compared to. It'll be this current winter from here on out as we've already essentially shattered records for mild winters in Seattle, but I have received quite a few emails from people wondering how long can we expect this pattern to continue?

Specifically, they've asked how long it took after those aforementioned two winters to "get back to normal"?

Sunday's soaking showers stats for Seattle

Sunday's soaking showers stats for Seattle

Seattle's little-known fact outside the local area is how we get rain quite often, but it usually comes in drips and drizzles and it's why Seattle ranks behind several other U.S. Cities in annual rainfall.

But Sunday? Not so much.

I focus a lot on Northwest photography in my weather blog - and why not? The natural beauty here is the gift that keeps on giving.

But in today's blog, I'm spanning the globe to showcase some of the gorgeous scenes Nature provides, via a compilation of time lapse videos.

El Nino finally here, now that the party's almost over

It was supposed to the guest of "honor" at the annual fall and winter festivities in the Pacific Northwest this year, but as we all stood milling around, El Nino was fashionably late.

Then it was pretty late.

Then we all started glancing at our watches. Did El Nino get lost? Did its GPS lead it astray? Car broke down?

'Partly sunny' vs. 'mostly cloudy' -- yes they mean something different

It's a surprisingly common question we get around here: "What's the difference between 'partly sunny' and 'mostly cloudy'? Isn't it if it's one, it's also the other?"

Yes and no. At least for the forecasts written by the National Weather Service, there are very specific definitions in their zone forecasts that are broken down into each region.

(You've likely seen those forecasts -- for instance, they're the ones in all caps you see if you've ever been a fan of "Weather on the 8's" on a certain dominant national weather channel.)

Walk around the Puget Sound area and you'll notice trees starting to bloom and perhaps the whirr of a lawn mower or two, even though winter still had a solid 3-4 weeks left in its reign.

Seattle finished up February as the warmest on record, on the heels of a very warm January (and record-warm December) as well, and the early spring-time weather has in tandem brought out the first signs of spring.
