The Last 70 Degree Day of the Year?

It is a bit depressing....

Today is probably the warmest day for the rest of the year in western Washington.

The last day temperatures in western Washington rise into the 70s.

The high temperatures today (Tuesday) are shown below. Lots of 70s around Puget Sound, with some low 80s over SE Washington.   Similar in eastern Washington.   It was wonderful.


Such temperatures are well above average and will plummet tomorrow as cool ocean air pushes inland.  And such warm temperatures will not return this fall.

To show you this depression situation, consider the latest surface temperature forecasts at Seattle and Pasco for the next 10 days (below).

Seattle HIGH temperatures will be in the low 60s and upper 50s through October 18.   This will feel quite chilly after the warmth of last summer.


Pasco will start in the low 70s the next few days and then decline into the 60s.


 A series of frontal systems will be moving through during this period, with rain spreading over our region.   For example, the total precipitation through Monday morning is quite substantial over the Oregon Cascades and the north Washington Cascades.


Obviously, this cool/wet weather will speed up the decline of the few remaining wildfires in the region.

The Northwest Interagency Coordinating Center has a graphic of the flammability of surface fuels (called ERC).   All regions of the area will become MUCH LESS flammable (going from red to blue in the graphic below).


Since the burned acreage this year is currently below normal over the region, we are guaranteed to end this year on the low side.

  1. Here on the Quimper P folks noticed many more yellow jackets than usual, followed by an amazing number of September spiders. Are the bug populations higher due to the warmer than average summer?

    1. There have been a lot more spiders this year out on the coast as well compared recent years. Haven't seen any yellow jackets. Wasps seem to be more common.

    2. I agree, I saw LESS flies, mosquitoes, and yellowjackets than most years. Almost didn't need bug repellant while hiking this year.

  2. Cooler! East of the Crest, wood stove season has already begun.
    The rain will be welcomed.
    From just north of Yakima, on I-82, there is a good view to the west and Mt. Rainier. At 1 PM Tuesday, smoke (white/gray cumulus-like) from the Wildcat Fire near Bumping Lake was streaming northward. At 6 PM, the colors were orange to dark and more spread out. A related note is that Blewett Pass is now opened with restrictions (Labor Mountain Fire response activity still going on.)
    It is time for these fires to be put to sleep.

  4. In other words: A/C season has finally ended.

  5. Power lines absolved: Federal authorities announced that they have arrested and charged a Florida man with maliciously starting the Palisades Fire, one of the most destructive fires in Los Angeles history.

  6. Tomorrow is the perfect day to head south for the next 6-7 months.

  7. I'll go out on a limb and say that we struggle to even hit 65 for the rest of the month. However, we will hit that mark in early November, but it will be associated with just enough rain and wind to make outdoor activity needlessly complicated.

    1. I try and remind myself daily how fortunate we are here in the USA to be free to come and go as we please, and enjoy November any way we like. We could have had the unfortunate luck to have been born and living in a wretched place like China or Russia, but we didn't. I try to count my blessings every day.
