The Origin of Northwest Heatwaves and a Toasty Weekend Forecast

 Everyone is talking about the warmth.   

Yesterday, high temperatures around Puget ranged from around 60F near the water to 80F in the lower Cascade foothills (see below, click to enlarge).  Today---add another 3-6F.    So low 80sF are pretty much guaranteed at some locations.

Around the region, temperatures were in the 70s around the Columbia Basin but fairly warm along the coast, the result of easterly flow keeping the cool ocean air at bay, while cooler air pushed into eastern Washington and Oregon.

My podcast today will provide a detailed forecast for the region and then explain the mysteries of Northwest heatwaves.

  What allows temperatures to soar 15-30F above normal?     What is the ominously sounding "thermal thought."  These and other "hot topics" will be discussed in my podcast!
