Everything appears to be in place for a VERY hot day across Western OR/WA.
1. Offshore flow developed overnight and is stronger than I expected, almost 3 millibars Portland to The Dalles (PDX-DLS) right now. That’s about the same as the June heat wave. So east wind may make it close to the airport, for sure to Troutdale/Gresham/Camas.
2. 85 degrees at 6am at 1800′ on our TV tower…that’s impressive.
3. No high clouds to interfere.
4. If an east wind actually briefly makes it to PDX, I could see 105 or 106, otherwise 104 still looks good.
Looks like all models are latching onto upper level moisture moving overhead tonight/tomorrow. That may do 2 things: 1. A very warm night…maybe 70-75? and 2. Cut down on heating tomorrow, a thick high cloud cover could keep us near or below 100 of course.
And a bonus to the heat wave…I had to get up at 6am this morning for KXL radio, so I made a coffee and went outside to water plants. Nice and warm already. With a warm night it sure smells good outside with plants blooming. Kind of like a visit to Florida. Of course the payback is the heat this afternoon.
Stay cool, and we’ll see if it IS the warmest day since 1988…Mark
