Warmer Weather Ahead

Snapshot Apparently I chose the wettest, coolest, most useless days to take off in the month of August.  I was off Monday-Wednesday, although Saturday and Sunday were neat with the thunderstorms and nice warm nights (Luckily, I have a heat pump that keeps the house cool during the day).

I took my usual between-show ride this evening.  It's obvious that I can only do that for a few more weeks…that sun angle is getting pretty low by 7:30 pm.  And in two weeks I'll won't be able to even start until 6:30pm.  Well, I'll be back at it in March.

As for weather?  It's a bit slow this evening.  Clouds gradually clearing out behind all the muck of the last few days.  Plenty of clearing and wet ground should lead to some fog or low clouds later tonight.  Weak or slightly offshore flow tomorrow and Saturday plus 850mb temps peaking out around +16 should give us highs in the mid-80s Saturday.  Earlier I had a 90, but that was based on the "east wind" part of my chart.  As I mentioned, 00z models have very weak or light east flow on Saturday, so I dumped that 90 degree idea as fast as Northwest weather geeks run from high pressure and inversions in the winter.

Models seem to be slightly faster with the next trough/cold front for late Sunday.  Looks like the Coast may be wet the 2nd half of the day, with rain into the interior by sunset.

Some sort of ridging and warmer temps comes back in the middle of the week.  Mark Nelsen

    An absolutely perfect day for power-washing the backyard. How’s that for excitement!?:-)

  2. Triforceofinvisiblity says:

    I had a high of 80F and partly cloudy with the west part being the cloudy part. 😀 (big grin)

  3. Atmospheric Wrath -Far S.E. Portland- says:

    Hmmm I see Mark has bumped tomorrow back up to 87.
    Must be some light offshore flow 1 to 3 mb or something.
    That’s the only thing I can think of.

    Eternal Yamcha I would LOVE to see those windcharts as I am a big wind fan. 🙂 I don’t care how amature it is as I amature myself. Just as long as I can read it. 🙂
    Mom said Mon and Tues is suppose to rain I assume she got it from the HDTV which there is this station with this neat 24hr webcam of Portland that is live and streaming plus it shows different shots of Portland and the weather around our area.
    Ummmmm It’s 78F now and partly cloudy.

  5. Atmospheric Wrath -Far S.E. Portland- says:

    Hmmm for some reason the models missed these east wind. Very weak/light offshore flow was expected and yet I see Corbett has consistently been 25-30mph all morning. I am even having easterlies 5-12mph. In comparison the past several very light offshore flow patterns gave the western Gorge only light E wind under 10mph with little if any reaching west of there. Unfortunately surface gradient data and none of the MeteoStar sites are loading so when I check the barometric pressure between TTD(29.97in) and DLS(30.01in) the difference of -.04 which I believe is 1.2mb doesn’t justify the wind speeds.
    Locations in the northern Oregon Foothills/Cascades and the southern Washington Foothills/Cascades predominately show a WNW flow with the exception being Three Corner Rock E@29.
    Then I checked the cross cascade pressure difference between OTH (North Bend) and GEG (Spokane). OTH(30.02in) and Spokane(30.14in) and you end up with roughly 5mb of difference. Perhaps very weak to light downslope flow, but not much and you’d see that reflected in the higher elevations which we are not.
    Then I checked 12z WRF-GFS 4km wind model and it shows little if any easterly gradient to speak of and very light winds. So I guess I am a little baffled by this.
    Maybe I over analyzed the situation lol I just wanted to look into it. The weather is slow……
    Any thoughts?

    I had some low clouds and fog hanging just over the tops of the houses in my neighborhood. It cleared out really quick as I drove west into Hazel Dell.

    If we could get summer back for 2-3 more weeks, I’d be satisfied. Think you could help us out Mark?

    More like partly cloudy skies now. Currently 47°

  9. Mike (Sweet Home) says:

    Nice clear skies this morning and a little on the cool side.
    Temp 45.9°
    DP 42.8°
    RH 89%
    Winds are calm

    Thanks for the update Mark!!!!

    46 kirk? nice!!!!
    What a beautiful crisp August morning out there! Some virga draping down from above and a temp around 55. I was noticing some color changes on a couple trees as well…hmmmmm.
    Anyone else have fog this morning? Steve P reported some up in da COUV.

  7. Sad to hear you won’t be able to keep up with the bike rides much longer. My fiance was freaking out earlier today when she saw some coloring in the leaves. Doesn’t seem that long ago that I was thinking 60 was warm; guess it’s time to get back to that mentality soon.
    Speaking of the terrible weather; I decided it was time to warm up a bit for the stormy months coming and I’ve done one of my terribly amateur wind charts that I’ve done over the years. If there’s any interest in seeing the chart for the storm around August 19th/20th, I’ll post it somewhere (dunno where yet, sadly.)
    Keep on rockin’ Mark!
