Warm Weather Arrives

SnapshotLadies & Gentlemen…start your gardens!  I just ran over to a "local, yet national" home improvement store to pick up some supplies.  I ended up leaving with pepper, tomato, and strawberry plants;  it must be spring-summer fever!  Of course that’s based on looking at the weather maps too, I don’t usually lose control like that.  After scanning numerous long-range models, most seem to agree that we have a nice stretch of mild weather for the next 7 or more days.  That’s the big-picture this evening.  Of course the devil is always in the details so let’s take a look at the short term forecast first.  80 appears to be a very popular number today…take a look to the left.  It was our first 80 degree temperature of the season at PDX.  The atmosphere overhead actually warms up during the night as a strong ridge of high pressure holds over the West Coast.  850mb. temps reach +15 or +16 Celsius by midday tomorrow, then quickly drop to only +3 early Wednesday.  That’s due to a strong, but dry cold front passing overhead tomorrow night.  So how warm tomorrow?  IF it wasn’t for a sudden upper level cooling and an unusually strong marine push that starts tomorrow afternoon, I would go for about 84.  But models are very insistent on quick cooling to the overhead atmosphere after midday and that marine push beginning earlier than normal…quite possible in early May, unlikely in July.  So just a notch or two cooler is my forecast.  Our model here continues to show a few scattered showers developing in the leading edge of the marine push tomorrow afternoon.  Other models don’t show that so I’m ignoring it.
The big marine push would make you think a cloudy and cool Wednesday following it, but this much drier and well-mixed air coming in behind the cold front, so plenty of sun Wednesday afternoon.  Then we into a morning clouds/PM sun routine the rest of the week as a strong ridge sits over the Rockies and very weak troughiness stis out over the Pacific.  As a result…no rain in the 7 Day forecast again today.  That’s strange for May, but definitely not unprecedented.  We’ll probably make up for it with two weeks of cloudy, cool, wet weather at the end of the month right?  Mark
A small maintenance note…I apologize for the missing/incorrect links on my personal weather page yesterday and early today.  The NWS changed a bunch of their links to text information, which had me badmouthing them…at least to anyone within earshot in the living room.  But at least it made me finally clean some things up and add a few additional items as well.

    Well looks like I topped out at 82.4F.
    Onshore flow is definitely kicking it with Scappoose reporting NW winds over 25mph.
    What a gorgeous day though.

  2. Gregg-Troutdale says:

    78.9 here now, checking temps on west side and along Columbia river everyone in upper 70’s to 80 right now.

    On Shore Flow! On Shore Flow! On Shore Flow! πŸ™‚

    Well I’m in SE PA (hour north of Philly) once again for one more day. Pretty comfortable day here, temps in the middle 70s. Checking back towards the midwest (dewpoints are in the middle 60s) and temps at 85. It’s been about almost 2 weeks since I’ve had any rain at my house now. My newly planted flowers and tomato plants need some rain..
    Ever since my wife and I planted our roses and other plants it hasn’t rained a drop since.
    It looks like you guys are also in for some good weather. As much as I love winter weather, it’s nice not having to bundle up to just go outside!
    Nice to see you post again, Justin!

  5. Gregg-Troutdale says:

    77.7 here, low 80’s not out of the possibility.

  6. AtmosphericWrath -Southeast Portland- says:

    Wow. 80.6F now and it’s only 1:07PM. It’s getting a bit warm in the house almost need to turn on the A/C Lol.
    Maybe near 85F today assuming the onshore flow doesn’t kick in.

  7. AtmosphericWrath -Southeast Portland- says:

    I’m already 76.6F running 4F warmer than at this time yesterday.
    Assuming the onshore flow holds off I could reach the low 80’s.

    Chucky here’s another link regarding the system on the East coast.

  9. Gregg-Troutdale says:

    Ive been watching that Chucky its a hard call, especially this early in the season, and NHC doesn’t think much of it either. Next 12-24 hours will tell.
    What a great weather day again today, with temps already approaching 70. Got an early 18 in this morning. Should easily be upper 70’s to around 80, if the cooling doesn’t move in to soon.

  10. Aleta says:

    Steve, I believe your right. He mentioned on a posting last fall maybe?? I remember thinking he was about my age so 38 or so would be right.

    Check that out!
    Even in the gulf stream waters are probably still too cool to support tropical development. Doesn’t look like TPC thinks they’ll be any development either.
    Interesting to see something, even though it’s not tropical, like that this early in the year.

  12. Steve Pierce - Vancouver says:

    Two questions:
    1. Does anyone know how old Mark is??? Should be about 38??? What an old man. πŸ™‚
    2. Has anyone seen the round (radar looking) dome on the top of Mt. Scott lately??? You can see it from I -205 very easily. Any idea if that is what it is? Maybe another station in the local market getting the radar itch?

    Rod apparently thinks we have a storm threat? I would say thats unlikely but I do see what he is noticing.

  16. Nof says:
