No big changes in the forecast the next few days. Within the next few hours, easterly flow begins from about 1,000′ to 6,000′. That continues until early Saturday afternoon. The reason is high pressure moving south out of Canada and into the Columbia Basin…a bit more like Fall then Summer. We should get 3-4 millibars easterly gradient in the morning PDX-DLS. The east wind may briefly make it as far as PDX, but more likely it’ll only be east of I-205.
Theoretically this makes the temperature forecast simple using the Magic Chart. Tomorrow is about 87, and Saturday will be somewhere between 90 and 95. I’m leaning towards the high end of that range in the 7 Day Forecast.
Okay, discuss…Mark Nelsen
