It’s tough to get “sleddable” snow when not much of ANYTHING falls out of the sky. That happened in much of the Portland metro area today. Lots of sunshine, sparse shower action, and very little precipitation. In fact PDX only recorded .05″ yesterday AND today combined! Officially we squeezed out 0.5″ of snow last night and early this morning. The daily total continues through midnight so that could change since we’re seeing plenty of snow showers right now.
I don’t think I saw a report of more than 2″ anywhere in the metro area (so far!) except out in the Hillsboro, Banks, Forest Grove areas. That includes Clark county and the western Gorge too. Most of the showers didn’t do much once they passed over the Coast Range. Of course with some sunbreaks and temperatures above freezing, that little bit of snow melted by early afternoon.
Remember I forecast Trace-3″ in the last few blog posts. Yet there was MORE snow than expected in a few places. Salem, McMinnville, Forest Grove, Longview, Lebanon, Albany. Models had hinted there would be some “training” of those snow showers bands and it did happen. But just in a few spots.
Someone was harassing me on Twitter about the forecast (always wrong, etc…) earlier. How would YOU handle a situation like this when some random spots will get a lot of precip and others will not? On a normal showery weather day hardly anyone would notice if we get 0.45″ vs. 0.15″ rain. The only difference now is that temps are near freezing = snow. Then everyone suddenly cares (for good reason) NWS decided to forecast for those highest numbers and issued a Winter Storm Warning to cover it. I chose to miss those high numbers and focused on what I thought most would get (Trace-3″), hardly mentioning the warning.
This evening the very cold arctic has made it to just north of Longview and east of the Cascades to Arlington.
That “arctic front” is now falling apart and we’ll just see a little filtering of that arctic air down into our area. We won’t be 23 degrees like what Seattle is seeing right now! The surface low and nearly dead arctic front is just south of us tomorrow morning
Snow showers have picked up a bit the last 2 hours and that means we still have a chance for a widespread dusting (likely) or even up to 2″ in the metro area (less likely). Roads are going to be very icy for the Monday morning commute!
The rest of the daylight hours Monday will be uneventful and most frozen roads slowly thaw. Main roads should be fine for the evening commute, just leftover slick spots where more than 2″ snow has fallen.
A “B.C. Slider” will be coming down the coastline tomorrow evening through Tuesday morning. That’s a little wiggle in the cold northerly jet that spins up a surface low pressure system and clouds/snow. A situation like this will be much different than what we are going through right now. This is a general/widespread light snow event. Temperatures will hover near freezing tomorrow night through the morning commute Tuesday. Most likely we pick up 1″ or so snowfall during that time. It’s unlikely we have a frozen mess Tuesday morning, but lots of slushy snow. Still, that’s not fun to drive on either! Then it warms above freezing again Tuesday afternoon for reasonable driving conditions many areas.
After another dry day Wednesday, another “slider” comes down the coastline. But that one is more likely to move inland NORTH of us. That’s important because a southerly breeze warms the lowest levels of the atmosphere quickly in this situation. We may go from snow to rain during that little precip event.
I sure don’t see a “snowstorm” with either of these two systems Tuesday and Thursday, but will be keeping an eye on things…
Enjoy the white start to your Monday!
