Warmest Day of 2013

A nice warm day today, even with mostly cloudy skies and a few sprinkles here and there.  62 is one degree higher than the 61 we’ve hit a couple of times:


It looks like the mild temps continue for two more days, then back to average or below average temps over the weekend.  It’s still interesting that models can’t seem to agree on what to do with Sunday and Monday.  The 18z GFS ensemble chart shows the operational run around -4 degrees at 850mb, but a large cluster of solutions continue to show temps up around +5 to +10 on St. Patrick’s Day:


The 12z ECWMF is similar, showing a good cluster of solutions around -5 on St. Patrick’s Day, the operational about -4, and a whole bunch of them suddenly jumping temps (or keeping them) between +5 to +10 later Sunday and Monday.  It’s rare to have such disagreement just 5 days out. 


It’s a matter of how deeply the cold trough digs down across the western part of North America Sunday and Monday.  If it stays farther north, we remain much warmer, if it comes right down over us, snow levels around 2,000′ or a little lower.

Regardless, it seems that we’re headed for cooler than average weather next week.  That’ll be the week just BEFORE Oregon’s Spring Break.  I’m sure we’re getting the cool weather out-of-the-way early so it’ll be 60-70 each day DURING Spring Break…right.

  1. I had a high of 68° here today. Fantastic! More please!

      Nice! My high temp topped out at 63.5° this afternoon. Still warm out there – 62° at 5:45 PM.

    18z GFS flirts with some fairly low elevation snow levels about 8 days from now…. maybe even seeing some in the air near the valley floor. -7/-8c, 522 thickness, moisture. Interesting. See how that develops.

  3. runrain says:

    Super spectacular day out there right now!

  4. GTS1K says:

    Mostly sunny and 58!

  5. Tyler Mode says:

    Still raining here at the beach. It’s mild though.

    A new Pope has been elected! Maybe now Portland will start getting more snow in the winter now that there is a new connection to the Almighty. Mark, make sure you get the new Pope’s phone number so he can say a prayer for us all next winter here in the Pacific Northwest to get more snow. 😉

    I would love to have a nice sunny spring instead of one where it surprise snows on April 5th and you’re stuck out in it in spring clothes.

    Also, more sunshine = more leaves on trees. I’ve missed leaves.

    You gotta figure out that Sunday morning forecast soon, Mark; lots of Shamrock runners eager to know! 🙂

    Folks, please don’t rehash old arguments or past issues hoping to restart some sort of drama. And please don’t reply to this comment because then that would make me the “drama instigator”.

  11. This won’t happen.

      Actually, knowing our luck and going off the trend from recent years, it just might! 😆

    • gidrons says:

      The Euro 00z has a little different setup but very similar 850 temps. Both models would be cold enough for snow at my house on the first day of spring.

    • Benjamin (West Salem) says:

      Erik said it right on, we can’t get cold temps and precip together at the same time to save our lives during the “winter” months, but here comes the end of March and we could end up seeing some snow….. maybe,

    • W7ENK says:

      I was being mostly facetious… mostly. :mrgreen:

      It is a sad state of affairs though, in’nit? Seasonal lag to a severe degree, it almost seemed like our seasons were approaching 90 degrees out of phase, nearly a full season off center. Winter in Spring, Spring in Summer, Summer in Fall, Fall in Winter… and repeat. Let’s hope that cycle finally gets broken this year, eh? I’d hate for it to shift by another 3 months — could you imagine? Then we really would be 55 degrees and damp all year long! Yuck!!

    • gidrons says:

      We’ll see. In my opinion, models are the least reliable in the March-May time-frame. They struggle with cut-off lows.

  12. Timmy_Supercell (Klamath Falls @ 4200') says:

    64 / 25 @ KLMT today. Surely was beautiful.

    39 degree difference too!

  13. GTS1K says:

    Nice afternoon.

    56.9 here – no rain…

    …that’ll do.

  14. WX Ninja says:

    Sorry Mark, I was asking Ashley if he wanted me to sell him a house not you. Your house seems to finally be in the shape you want it to be in, no need to sell just yet :). I will say its much nicer looking at houses in this type of weather than in the rain. It definitely felt warmer out today, hopefully the warmer solution wins out for the 17th.

  15. Somehow the timing got off this year. Usually spring-break is the cold week of the month. So maybe we get this outta the way and actually have a nice break for the kids………..nah, never happen! 😉

  16. W7ENK says:

    I’m about ready for a string of 60-70 degree days.

  17. Tyler Mode says:

    Even our warmest and driest Marches and Aprils feature rain during spring break:)

  18. Dave in SW PDX (235') says:

    Definitely a short-sleeve shirt kind of day out there; it sure felt nice this afternoon. It would be great if the clouds would clear out a bit more to allow a peek at Comet Pan-STARRS this evening, but that’s probably asking too much.
