While the heart of the US endures continues heavy rain and storms thanks to a large upper feature, the heat has been on back West with record heat over California. Monday saw the hottest weather of the year with highs topping 110 in both Fresno and Bakersfield in the Central Valley but as an upper feature pushes into SoCal and a trough digs into the Pacific Northwest, this heat is soon to be tempered.

As for the rest of the country, well the cool, wet theme continues for the Plains into the Mississippi, Tennessee and Ohio Valleys. While it was your typical summertime warmth on the East Coast. That warmth gets replaced by cooler air from that upper level system late this week but it’s not heat, but more cool which dives into the West as we head for the weekend.

Here was yesterday’s highs, note the 60s for Chicago, only a 70 in Kansas City. Widespread coverage of 70s. Note bad at all for the 2nd week of June.

Here’s the current 500mb height anomalies. Note where it was coolest, right beneath the upper low. Ridging and SW flow to it’s east, pumped 90s up as far as Virginia but only mid 70s for the New York City area.

As we skip ahead, a reinforcing trough dives into the Pacific Northwest and with another upper disturbance also pushing into Southern California (one now and another late week), expect the deep marine layer to linger through the next 5-7 days. It of course deepens after sundown and will have a hard time burning off at the coast even by mid to late afternoon. Low cloud, fog, even drizzle may get pretty far inland.

That PNW trough spreads south and east through this weekend, keeping things comfortable if not cool across the country.

As the system pushes northeastward, so the wet weather spreads east too.

Note the lack of below normal heights this weekend.

That PNW system pushes east across the north through the weekend, deepening the trough in the West but in turn, the ridge builds along with a warming southwest wind into next week. Notice the positive heights appearing by Monday.

The very areas currently cool and wet, will be warm this time next week if the GFS is right. However, keep in mind that the ground is wet, this will have impact on temperatures not just next week but throughout the summer.

It looks like we have our first shot at 90 from Philly up to Boston mid next week as the western trough slides into the Plains with the core of the ridge pushing into the Northeast.

More troughiness settles into the West as another system enters the PNW and also spreads east.

500mb chart at 204 hrs.

Continued wet through the next 5-7 days from the Plains eastward.

Here’s the rain over the last 30 days and note where wet, it’s cool now through the next 5 days before warmth tries to push in but I think these very wet areas will continue to attract cool, not warmth the rest of this summer.

Despite the warmth in the East next week, the overall theme is not for warmth but cool. The CFSv2 keeps with the idea of cool for much of the country through the next 4 weeks.

Here’s the CFSv2 for June, largely BELOW normal temperatures across the US.

It’s not seeing much warmth in July either. Fits nicely with my summer idea and reflects the fact there’s a lot of water in the ground.
