Snow Wrap-Up & Brief Look Ahead

February 5, 2019

Noon Tuesday…

That was fun wasn’t it?  We avoided a rush hour mess yesterday evening by only a couple hours.  Around 7:30pm I was thinking we’d get nothing more than a dusting in much of the metro area and was about to “call off” the Trace-2″ forecast for east metro.  Then radar started filling in and it snowed lightly well into the overnight hours.  At the official Portland snow observing site 1.4″ fell from this system.

I just spent an hour working (playing) with my Craigslist special snow blower.  I had it parked in the garage and assumed I wouldn’t need it this year.  Instead somehow I ended up with 1.5″ yesterday and another 5″ during the night around 1,000′ east of Corbett!  There is nothing more satisfying than a clean driveway.  Sure it’s fun, but it would get REAL old after 3-4 months in a snowy climate.

A few thoughts

  • This was a rare situation where we were able to get a metro-wide (light) snowfall and widespread temps below freezing.  That was WITHOUT a cold east wind blowing out of the Gorge.  That’s because the cold/dry modified arctic air came down from the north instead of from the east (through the Gorge)
  • Total snowfall was close to the forecast as well.  It’s never EXACTLY as we say, but this time things worked out in the end.
  • Dusting to 2″ was right on for central/east metro and Clark county.
  • 3-5″ far eastern areas and into the Gorge was close and it was very elevation-driven out there.  Models showed maybe 8″ or more in central/eastern Gorge.  Looks like that happened in spots above 500′
  • Nothing to a Dusting was too low a forecast for west metro and down to Salem.  Some spots had up to an inch west side and down into the valley.  Still, the ECMWF forecast from yesterday was reasonably close

Temperatures are S L O W L Y climbing early this afternoon, climbing above freezing in sunny spots and a bit slower to rise in cloudy areas.

Skies should clear all areas by sunset.  Of course that means we’ll see icy areas in the morning but not nearly as widespread as today because no fresh snow will fall and many streets will dry out the rest of the day.  All freeways/highways will be fine.  It’ll be side roads/streets that remain wet today.

With clear sky, dry air, and still reasonably long nights this late into the winter, we’ve got a cold night ahead.  Temperatures drop into the upper teens in the coldest areas and at least 25 here in the city.  It’ll be the coldest night of the season so far, but that’s not too tough to do considering how mild it has been.  Those aren’t “pipe-busting” temps generally, but your plants will suddenly realize spring weather is not happening in the first half of February!

Looking further ahead

The next chance for precipitation (rain or snow) isn’t until Friday, any maybe not until later in the day.  Not sure if it’ll be cold enough for a widespread snowfall again or not, but the possibility is there.  I’ll look that that more closely this afternoon and we’ll see what it looks like after evening models come in.


A full listing of snow totals can be found at the link and I’ve copied the 10am version as well.
