Snow Storm #3 Delivers; A Cold Night Ahead

February 22, 2018

10am Thursday

Around midnight the central/west side of Portland was nailed by very heavy snowfall.  While driving over the Marquam Bridge I couldn’t see anything except the edges…like being out in space.  Pancake-size flakes were instantly smothering everything in white; quite a neat drive and my snowiest since a night in January 2012 (I was inside for last January’s big snow).

The storm sure delivered for most of us and 1-3″ snow forecast was perfect.  The far eastside got less than 1″ and I see some complaining that another spot or two had an inch or less.   Salem didn’t quite get an inch, but Eugene was nailed…lots of 1-4″ totals down there.  And I see Astoria, Tillamook, & Seaside all had 1″.

Almost everyone got SOMETHING which means this storm gave us the best coverage region-wide of all three.  

The official total at the NWS office was 2.1″   

It made for a nice pic from Clifford Paguio this morning:

One thing that has much different with this storm?  Temperatures remained right around freezing through the event.  That means main roads only briefly saw a big dumping of snow, then it either melted or was plowed off.  So I see some schools are in session today.

WHAT’S AHEAD?

The big news…WE ARE DONE WITH LOW ELEVATION SNOW THE NEXT FEW DAYS

Forecasting is much easier now.

TONIGHT

  •  Clear skies tonight + dry air + cold airmass + snow on the ground = COLD!
  • Lows could easily dip into the teens in some outlying areas with snow on the ground, we may drop below our 23 so far this season at PDX too if mixing east wind stays away.

TOMORROW & THE WEEKEND

  1. Skies cloud up tomorrow and precipitation arrives in the late afternoon or evening, temperatures will be above freezing at that time
  2. A strong onshore flow and warming atmosphere means at BEST we’ll have snowflakes mixed in, but then the sticking snow level jumps up to at least 1,500′ in most of NW Oregon through Friday night and into Saturday morning
  3. I DON’T EXPECT ANY MORE SNOW BELOW 1,000′ IN THE METRO AREA THROUGH THE WEEKEND
  4. A COUPLE INCHES ARE POSSIBLE ABOVE 1,000′ TOMORROW EVENING, especially in Columbia and Clark Counties where the cool air may linger a bit longer.

But the big story this weekend is the dumping we’re going to see above 2,000′ in the Cascades.  Yep, that says 2-3 feet of snow by Sunday afternoon on Mt. Hood.  Notice the NE Oregon mountains get nailed too.  Winter is here to stay for a while, although Spring in February was nice too.

Here are some other totals from last night.  Sorry about the formatting but free is a good price for this info from our friends at the NWS Portland.
