Another day of record temperatures is expected.  High pressure will continue over the western U.S. but will slowly weaken over the next week (see map below).  The main weather feature for the next 48 hours will be wind.  Winds will begin to increase from the northwest and north this afternoon and shift to the northeast and east tonight. Strong and gusty northeast to east winds will occur tonight through midday Wednesday.  Winds will be light Thursday through next weekend.  Temperatures start to cool Tuesday but will still be 3 to 6 degrees above normal by the weekend.  

While longer range models show the high weakening it still looks dry through the 20th of September.

  1. Saw this in Forbes: "The upcoming weather pattern setup is extraordinarily rare, according to the [Portland] National Weather Service, with an arctic air mass more typically seen in January moving toward the area. 'The end result is an early September weather pattern that probably occurs in this magnitude only 2-4 times a century,' the National Weather Service said, adding, 'this offshore wind event is literally off the charts for this time of year, and by many measures.'" Is this really as unusual as they are saying?

  2. I am no expert but I have watched the weather since I was a little boy growing up in the NE. I have lived here for 41 years and this is just off the charts for me. Now what this gentleman says I kind of get it, but what does this say for the winter. Northeast wind is kind of rare. Remember the winter of 1990. Super freeze for No. Cal. 19F for days killing many trees hardly any rain Is that where we are going? This is very tough to live with for so long. Thank you. So I guess my question is what does this mean for the winter? Thank you.

  3. Just one more comment. Look at that setup of the High on the surface map. back to back and far north. It looks kind of scary to me. Do we have to wait for the days to get so short that heating is only for a few hours

  4. The rare part of this weather event is the strength of the high pressure area that extends from the southwest US into Gulf of Alaska. You see this by how much we are exceeding record temps even with smoky skies. The wind portion of this is not uncommon but is a few weeks early. Strong northeast to east winds are common in Oct and NOv. 2017 we had the fires in the Santa Rosa area and in 2018 the Camp Fire that wiped out Paradise. That said I have never seen this type of wind event with so many ongoing fires. Could be really bad the next 48 hrs. While no rain in sight but the high will begin weakening.

    Stay Safe

  5. Discouraging forecast unfortunately. Must be 2020. I hope the Claremont fire doesn't make it down to the valley, like 2018 Paradise fire. That would be catastrophic. Oroville, CA is right in the path if that happens. Luckily, it looks like the winds will not be too strong down there.
