A Chilly Night

Snapshot Looks like a chilly night on the way tonight.  A very cold airmass is overhead, dewpoints have fallen into the 30s, and skies are partly cloudy to mostly clear.  I drove down to Lamb Elementary in N. Salem for a school visit today and noticed a few peach tree orchards in bloom.  I have a feeling anything lower than 30 would be very bad, so hopefully most spots will just touch the freezing point.  For those of you concerned about freezing, it's good news that we'll only see one night of the really cold temps.  A slightly warmer airmass is over us tomorrow night and then it's on to a cloudy and warmer one Thursday night.

Showers were a bit more intense than I had expected today, but at least we did see plenty of sun inbetween the showers.  Looks like snow briefly stuck down to around 1,000' overnight, but then showers tapered off later in the the night, minimizing any accumulations.

No change to the forecast thinking the next few days.  All models give us some rain as a warm front brushes us Thursday night and Friday.  Then much stronger ridging takes hold for the weekend and early next week.  There is a subtle trend in the 12z ECMWF and now the 00z GFS for a slightly weaker ridge Sunday-Tuesday.  I'll ignore the 18z GFS…it looked almost "hot".  850mb temps on Sunday and Monday on the 00z GFS are still up around +13 to +14, which prompted us to put an 80 degree high in the 7 Day Forecast.

    Watch the trough after the ridge, could be a pretty one 🙂

    Jeez Mark you are so picky. What, do you think you own this blog or something…:)

  3. Mark Nelsen says:

    I don’t mind if other areas get discussed on here (the weather), as long as the weather is slow in the Pacific Northwest. But the discussion below could be confusing when we have a snow threat here, so that would be a bad time. During active weather here, please don’t have long conversations about weather elsewhere.

    Bob – we’ve had a number of former area residents take up roost elsewhere and report conditions time to time. Thus far, it’s never threatened to derail the blog’s focus on our area and I think most of us find it interesting to hear what’s going on elsewhere from people who have had the experience of living in the NW. During a slow period like this here, it’s particularly interesting!

    MAN That’s A LOT of precip for that area and snow.
    I bet there is going to be TONS of power outages due to it being wet n heavy.

  6. Bob says:

    Maybe i am missing something, but what does Ft Collins, Co weather info have to do with PDX ???

  7. Mike-Mult Villige now in Ft. Collins, CO says:

    This morning in Ft. Collins we’ve slipped to 37 degrees and rain. The 06Z GFS outputs 3.29″ liquid from now thru Sat night. Trend has been wetter with latest model runs. The WSW storm total is currently 10-24″ for this area. Expecting changeover to mix this aft/evening.

  8. TetraforceofTime also The destroyer of bad-boys says:

    Does anyone know why Western Weather isn’t working?
    I like Andy’s model posts as he is VERY informative.

  10. Low of 29.7° this morning, currently sunny and 37.8°

  11. Ryan (Walnut Grove) says:

    That would be correct. A Houston loss and San Antonio Win gives SA the division and the tie breaker. So Houston is the 3rd seed.
    In Round 2 the Blazers would face most likely the Lakers if they get past Houston.
    Weather – It was actually colder at my place this morning than yesterday morning. Down to 37 today vs. 40 yesterday.

  12. Ian *Longview* says:

    timmy, apparently since san antonio won their division, they get the tiebreaker for the simple fact they won their division.

  14. timmy - scappoose says:

    can someone explain the tie breaker to me? houston lost, and if san antonio wins as well as the blazers, who gets 3rd?

    Mike,
    My brother went to the U of Denver. 70+ degrees one day, a foot of snow the next. It sure can change fast there. He spent a lot of time in the mountains, not so much at school and became a very good skier during his first couple of years there.
    Clouds starting to break up. 47 in Hillsboro at noon.

  16. TetraforceofTime also The destroyer of bad-boys says:

    One degree higher then you Andrew. 38 + Andrew being a 37F = no frost but warm 75F weather is on it’s way here taking The Express.

  17. Looks like PDX will have perfect weather for anti-tax Tea Party rallies! 😉

  18. Mike-Mult Villige now in Ft. Collins, CO says:

    Speaking of winter, a WSW storm watch has been issued for 10-20″ of hvy wet snow. This storm will be a headline maker for much of Colorado and the neighboring states. This excerpt from the overnight Denver AFD was interesting,
    SNOWFALL AMOUNTS ARE
    DOUBLY DIFFICULT TO NAIL WITH THESE MID APRIL STORMS. I`VE SEEN IT
    RAIN ALL NIGHT UP AGAINST THE FOOTHILLS IN BOULDER…THEN THE SUN
    RISES AND THE EASTERN METRO AREA GETS 1 TO 2 FEET OF SNOW WHILE THE
    RAIN KEEPS FALLING AT THE HIGHER ELEVATIONS TO THE WEST.
    This storm will provide much need moisture for the high plains.

  19. Punxsutawney (aka HIO Phil at work by Sunset High ~280' elevation) says:

    More of a winter than spring morning out in Hillsboro with a temp of 30.5 when I left. Lots of frost on the roofs, cars, and grass out there while riding in to work at 6:00am. It will be interesting to see how long the low clouds stay around today and how warm we get.

  20. Snow-Zone/Monmouth-Elv200' says:

    Wow quite cold out side 31 with lots of frost and it is cloudy.

  21. Andrew Johnson (Silverton) says:

    37 currently

  22. TetraforceofTime also The destroyer of bad-boys says:

    For KSLE Airprot (Salem) The record high for April is a whooper 88F

  23. Thanks for the update mark!!!!
