Cold Spring Night

SnapshotA quick drop in dewpoints this afternoon along with temperatures holding steady heralded the arrival of a much cooler airmass into the Northwest.  A nice little line of showers brought hail to them Portland metro area in the early afternoon too.  I noticed the temp even at the top of our transmission tower (1800′) didn’t dip much below 40 degrees, so any snow mixed in was short-lived.  But a cool and breezy day in general.
Very weak ridging develops over us the next 3 days, cutting off most of the rainfall.  But we’ll be right on the edge, with wet days in Seattle and guaranteed dry in Eugene.  Great…tough forecasting coming up again.  Spring IS the toughest forecast season west of the Cascades in my opinion.
One trend I see in the 00z GFS and 00z GEM is cold troughing for next week.  Just in time for Oregon’s spring break it appears that we’ll see a cold & showery weather pattern…Mark

  1. I’m sorry but I just have to say this. There is really NO WAY that its going to snow anytime during the next two weeks based on what models are showing. Unless they completely flip and change, which is highly unlikely to be colder (models usually trend warmer this time of year as we get more toward the date of forecast), we will NOT be seeing snow below 1500-2000 ft at all. And being that after the next two weeks we will be in April, I think we’re done with snow anywhere below the mountains until later this year. And for the final time, the “precipitation type” that is shown on the IGES is NOT accurate!! Also, based on the temperatures that it is forecasting, and due to the fact that we will also see much more daytime heating due to a higher angle of the sun, there will be no lowland snow next week.
    Sorry to get all your hopes up, but I think it’s time to put the lid on all this!

    Wouldn’t that be a way to end “spring” break LOL. I’m ready for spring though, if I don’t get to go Bass fishing soon I might go crazy lol.

    516 thickness with thise cold spell if it holds..not likely but…that would be very low snow levels with major convective activity for us!

    Wow Sean that sounds nice. It is only 45.5 here now. Larch Mt has a nice dusting of snow on top. I live North of Washougal at 1000ft here in the foot hills. Silver Star is very snowy as well. Im done with this cool damp stuff I cant wait for sun and 80deg. But at the same time only 8 months until November and another winter!!!

    I’m sitting at a comfortable 76 right now. Original forecast was for 69 to possibly 70. Strong SW wind and a fair amount of sunshine. Though when you get these type of conditions during this time of the year. Thunderstorms are sure to be following soon.

    Got down to 27.9 here last night, I was a little surprised to see it drop that low. Looking at the long range, it looks like we’ve got a lot of cool, showery spring weather on the way. I think we can say bye to anything above 65 for a couple weeks.

  8. Ryan (Da Couve) says:

    I managed to drop down to 32 even last night. Had a decent layer of frost on the car.

  9. Derek-West Gresham says:

    32 here, nice little late season freeze.

  10. Austin-Ridgefield says:

    It got to 27.8 thats cold but not yet unusal for our area to bad precip is not even making it to the coast.
