Busy night, but dead weather

No nice picture tonight, since the weather is REALLY slow for about 3 more days.  High pressure is settling in and shifts east of the Cascades a bit tomorrow for light offshore flow.  That should give us about 5 degrees of warming combined with a warmer atmosphere overhead.

Friday will give us one gusty east wind day as high pressure settles into the Columbia Basin and Intermountain region.  I’m worried that could cap PDX’s high temperature close to 60 degrees, while the areas away from the gusty east wind pop up into the mid 60s.

I did some fairly serious  surgery on the 7 Day forecast tonight.   Probably more than day surgery, but not a total open-heart, days at the hospital sort of thing.  A trough swings overhead later Saturday quite a bit closer to us than indicated just 24 hours ago.  We get the ol’ warm season double whammy of strong onshore flow Saturday evening plus a much colder airmass above.  For example we go from +9 deg at 850mb early Saturday to -1 or -2 Sunday morning!  We’ll go from warm and sunny to chilly and showery in just one day.  Saturday’s forecast high is a real tough one.  Depends on the timing of the trough and marine push.  Could be 62 or could be 68, I’m leaning towards the cooler one.  Strong easterly wind in the Gorge early Saturday morning goes gusty westerly by evening…spring must be here!

After that just cool and showery off/on next week.  I’m headed out for a long vacation beginning Friday, so I’ll try to post a few thoughts tomorrow around 6pm before I go home.  Tonight’s 10pm newscast will be the last for me until Friday, April 2nd!

    Good morning everyone.

    Hmmmm 36.3 and falling. ? What happened to the other 100 posts….

  2. PDX Weather Nut says:

    New record high for today here at the house of 73 degrees. Not sure what it is at the airport. The previous record high for today was 71 degrees.

  3. brisk sunny great day

    Glad this winter wasn’t as awful as 1933/34.

    • Timmy_Supercell (Hillsboro) says:

      Was it a very dry winter?

    • Justin (Brush Prairie) says:

      No, it was actually one of our wettest winters ever. But it was the warmest winter in recorded history as well, and downtown Portland somehow managed to not record a single freeze the entire winter (it did snow a little, though).

    Have a great vacation

    Nice job on the upskirt last night in your late news broadcast. I guess you really do broadcast live. Awkward moment. Thanks for the beautiful weather today. Finally enjoying a sunny day off.

      What happened , what was shown, and who?

    • ken says:

      they were doing a live shot outside of a bar in portland and a girl did a can can girl kick and showed all of oregon her st patricks day undergarments. It was quite humourous the reaction that mark had. Like it has been said earlier in the blog–Nicely handled Mark

    I wish I was in Curry county this afternoon. It is well into the 70’s at the beach.

    4pm temps under NE winds.

    74 @ Red Mound
    72 @ Brookings

  8. Timmy_Supercell (Hillsboro) says:

    Maybe Aurora isn’t as much a great chance anymore, as NASA is saying the geomagnetic field is expected to remain quiet the next few days…


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

    It’s not everyday that you see HIO and PDX tied for a low. 30 degrees in this case.

    We saw the opposite of what typically happens in winter around here, where Gorge outflow and the urban heat island keeps things stirred up and warm on the east side of town and the wind sheltered areas west side cool off. Last night persistant NW winds kept the west side warm especially Forest Grove and lack of Gorge outflow allowed the east side of town to cool off.

    Absolutely nothing unusual about a freeze in Hillsboro at this time of year. Average last freeze for my station is April 21st.

    • Jesse-Orchards says:

      Sure, it’s unusual for PDX, though. In fact, this morning’s 30 is the coldest they’ve been this late in the season in 13 years.

      And of course, widespread mid-20s are pretty unusual for mid-late March.

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

      With all the La-Nina springs recently I didn’t realize that we hadn’t hit 30 at PDX this late. In regards to widspread 20’s I agree, and going forward from today most record lows for Hillsboro are in the upper 20’s or above which is one of the cooler low land stations of course.

  10. Jesse-Orchards says:

    Hit 26.1 out here this morning, impressive for this late in the season.

    Looks like PDX managed to drop to 30.

    Keep the plants in for now, because the models are indicating the possibility for another hard freeze early next week. Small intrusions of cold continental air don’t seem to want to get out of here this Spring. Not that I mind.

    • dabears (Hillsboro-Tanasbourne) says:

      I’m getting just a tiny bit tired of it. I’d like to actually have some living plants on my balcony at some point.

    • W7ENK says:

      Indeed, I am too. My avocado desperately ‘wants’ outside! She looks pretty cramped and sad all smashed up against the ceiling like that, but I’ve read that they need to be kept indoors if the temperature drops below about 38 – My safe mark is 40. I have no idea what I’m going to do this Fall… I guess I’m going to need to figure out how to properly prune it?

      Had a low of 32.0 last night. I was a little surprised, considering it was still 40 or so when I went to bed last night… at 3am. Temp must of dropped fast!

    • Hey W7…maybe a small greenhouse attached to a southern wall?

  11. Battle Ground Brian says:

    Very cold in rural Clark county this morning due to low dewpoints and calm winds.

    7:15am temperatures:

    24 Yacolt
    25 Battle Ground
    25 Brush Prairie
    25 Crawford

    Meanwhile, Northerly winds along the Columbia have kept things well mixed in Urban areas and in Washington county this morning.

    40 Forest Grove
    40 Scappoose
    38 Fremont Bridge

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

    Well it did make it below freezing out in Hillsboro. 31.8 at home when I left at 6:00am. It got warmer as I went east. 36 at SW 185th.

    PDX at 33 at 6:00am so a decent chance for them to make it to freezing.

  13. PaulO says:

    Oh – and you and your family have a great (and safe) vacation Mark! Sorry about the exciting weather you will miss :).

  14. PaulO says:

    Suddenly dropped to 31.8 in the front yard and 29.3 in the back, Montavilla neighborhood, NE PDX (not unusual for my 2 sensors to read this far apart – both away from the house and the regardless of which one is on what side…) Lot of ice to scrape ughh.

  15. Well if Mark goes on vacation, then we will probably get snow, a windstorm, thunderstorms, or something exciting! Could be almost anything in early spring, looking forward to it!

    Mark, have a nice trip, everyone else, enjoy the sunny days!

  16. k5mitch says:

    35.7 F
    N-NE wind @ 0.0

  17. Mr Data says:

    The temperature is 36.0 and a dropping.

  18. Ben Randall says:

    I think this model is dead on …

    At least for the temps on the coast Friday afternoon

  19. Mr data says:

    Why would you leave at 5:15pm Karl as it gets dark in just a few hours from then? 😕

    I will assume you have headlamps/night refelctors and all that safety gear to keep you safe.

    41F here and dewpoints somewhere below freezing.

    Gonna be a chilly one.

    Too bad no windstorms.

  20. Timmy_Supercell (Hillsboro) says:

    Just had to check in quickly… Any Aurora??

    Btw, thanks for the update Mark

  21. Karl Bonner says:

    Do you think that the south Valley down around Eugene-Springfield might stay mostly sunny through at least the noon hour on Saturday? I’m planning to do a “long” (about 2 to 2.5 hours or almost 30 miles) bike ride up either the McKenzie or the Mohawk this weekend, I’m leaning toward the Mohawk since I’ve never been more than about 5 miles up there. I could either go late Saturday morning or Friday evening beginning around 5:15pm. Dare I hedge my bets on a warm and sunny Saturday morning/midday, or would it be best to squeeze it in Friday evening, with me finishing the voyage just as it starts to get dark?

  22. Battle Ground Brian says:

    Nice leg kick on the 1040pm segment!

  23. Have a great vacation Mark!
