In last night’s post I made mention of the lack of real summer heat over Northeast in the coming 10 days while tonight I look at the West Coast where it appears a more active period is evolving. That means the core of the heat gets shifted east over the Plains through next week.

While there’s wet and windy weather set to push into the Pacific Northwest, a lot of the rain across the East shifts south with the trough.

Here’s the 120 hour ECMWF precip forecast and as you can see there’s plenty of rain focused across the Southeast and none for the Southwest while there’s decent rains over particularly the coast Pacific Northwest.

The flow is largely flat through the first half of next week which means that the heat which spreads across the Rockies into the Plains, may work into the Mid-Atlantic but there’s a fight as lows tracking east across Canada try to carve out a new trough over the Northeast US which pushes low humidity, cooler air south and east.

Here’s the ECMWF through next week, showing low pressure pushing into the West Coast and forcing the strongest heights and hottest air east.
