2012 Weather Blog In Review

December 31, 2012

Only a few hours left in 2012, and I’m working this evening (but only until 10:30pm!). 

Wondering who the top commenters were this year?  Here are some year end stats…

About 55,000 tourists visit Liechtenstein every year. This blog was viewed about 1,900,000 times in 2012. If it were Liechtenstein, it would take about 35 years for that many people to see it. Your blog had more visits than a small country in Europe!

In 2012, there were 363 new posts (didn’t realize I post that often), growing the total archive of this blog to 1,678 posts. There were 795 pictures uploaded, taking up a total of 284 MB. That’s about 2 pictures per day.

Ready for this?

Flurry Storm ’12 Update

December 31, 2012


Well, the drive to work was a bit underwhelming from 1-2pm.  Looking at the radar I was hoping to at least see some good snow in the air.  But from Troutdale to Beaverton (east to west), I only saw a few light flurries and bare/dry ground the whole way, plus it was totally dry from downtown westward.    Flurries did just drop a dusting out in eastern Multnomah/Clark Counties east of I-205, but I just missed it.

I think my 10:30am update was a bit of a overforecast, it looks like very few of us even saw a dusting.  The one exception was the northwest part of Vancouver…take a look at the radar at around noon:


Notice the one yellow area (the only one that appeared today) was right over SR500 and Hazel Dell.  That’s the spot that actually saw some decent accumulation.  Here’s a closer view:


You had to be within a couple of miles of that spot or farther north into Clark County to see anything other than a dusting.  Our SW Medical Center camera shows green grass and nothing even on the barkdust.  There’s little or nothing south of SR500 on I-5 or anywhere along I-205 south of the I-5 split. 

So yes, the worst of all possibilities has happened; it snowed at Steve Pierce’s house and almost nowhere else!  Here’s the “neener, neener, it snowed and my house and it’s just too bad it didn’t at yours!” picture to prove it from Steve!  The pic just shows a dusting, but I’ve seen reports of 1-2″ in the Salmon Creek area.


Well, maybe next time for everyone else.

On another note, PDX officially recorded -SN (light snow) at the Noon observation; that means that’ll go down as the “first snowflake” at the Airport for the AMS contest from the Winter Weather Meeting.

North & West Vancouver the Place to Be; Snow Sticking

December 31, 2012


The band of snow showers is moving overhead and you can see on radar http://weather.cod.edu/satrad/nexrad/send.php?type=RTX-N0Q-1-24 why it’s been sticking nicely the last hour from Scappoose/St. Helens over to Vancouver Lake and northern/western Vancouver area.  A heavy batch of showers right over them.  Take a look at the WADOT camera at 134th street on I-5:


Then compare that to just a few miles east on I-205…barely a dusting (so far).


The rest of the metro area is just seeing flurries or dry so far…

An Exciting Afternoon Ahead; Snow On The Way

December 31, 2012


Nice setup for widespread snow across Northwest Oregon temperature-wise, but how much moisture we get falling out of the sky is the big question this morning.  Read the previous post first.

The Highlights:

  • Snow showers may develop across the metro area between 11am-3pm
  • It’s cold enough that we’ll see a dusting in spots, probably not on roads except far westside and in the hills.  It might get slippery in the West Hills this afternoon.
  • It ends after sunset and skies clear…still clear and cold as we approach midnight
  • Any wet roads will refreeze; be careful later if you’re out and about.  Remember Trimet and many other transportation options are free tonight.

The only thing holding me back from expecting a widespread dusting or half inch of snow this afternoon across parts of the metro area is moisture availability.  The morning WRF-GFS model came in gangbusters showing a good 1″ of snow all over the metro area between 1-4pm today. 


But now our RPM has a dusting here and there, and at least enough in the air to get us all excited as a solid band of light snow moves across the metro area from 11am-3pm.  It’ll move slowly from west to east.  The first image shows the actual precipitation and the 2nd shows snowfall accumulation forecast.  Note that it’s below 2″, but still, a widespread dusting of snow would add to the New Year’s Eve fun wouldn’t it?

The MM5-NAM and NAM itself are pretty much dry and we may need to discount those models since radar indicates the wetter solution may be correct.

We’ve already seen sticking snow this morning in the Coast Range and in SW Washington north of Longview.
