Don't let this weeks warm up fool you; pot holes, frost heaves, mud and flood season is coming; light snow Wednesday night
Winter isn't over just yet
While the forecast calls for warmer weather, the region hasn't seen the last of the snow flakes just yet. It seems as though every year we get a warm up in March, and for those who are done with winter get excited that spring is here. The reality check comes when more snow arrives, and the forecast gets either ecstatic or angry responses.
In the nearly 50 years I have lived here, this is what I know to be true. It can snow anytime and anywhere in March. We have the annual April Fools Day storm, which occurs within a day or two of that point, and can bring snow, a mixed bag, or rain, and one, two or all three of those combinations. After that, snow chances typically begin to taper off as we head into April.
The coast typically sees the end of the season first, usually after the first full week in April. The western foothills on up into interior Washington County typically see the last flakes by the middle of April. The mountains and north could see the last flakes as late as the first of May. There are always anomalies to that. Yes, I am well aware the Portland's latest snow date is May 10-11, 1945 where 7.0" of snow fell. I also remember vividly the April 6-7, 1982 snow storm where nearly 16" of snow impacted the region. In the past 8 years I have been forecasting, I've had snow flurries on the chart for the north country in early May. It happens, which is why I am getting out in front of this and telling you that it's not time to put away the snow shovels and take the plow off the truck just yet, no matter how happy or tired of it you may be.
No, I am not predicting that we are going to get clobbered with some epic dumper that is in the long range forecast that I am not telling you about. In fact, for now, none exists. What I am saying is that I am not prepared to stick a fork in winter and tell you that it is over. You'll know when the time comes, and you will be free to celebrate or cry, whichever suits your emotions around it.
