Hot West, soggy East and unusually cool inbetween

We have a blocked up pattern this week across the United States with ridging up West and East coasts with an unseasonably cool trough in between. The week opens with heatwave conditions into the Pacific Northwest interior as well as up into New England. However, with the ridge axis out over the Atlantic and closest to New England, here is where is warmer and drier but due to the trough being centered over the Mississippi valley, we have a very wet week up through the Appalachians and coastal plain Caribbean moisture running up the coast.

Here’s the next 5 days off the GFS ensemble.

Note the warm west and New England, cooler in between and where there’s a lot of rain this week.

Expect flooding or even flash flooding over parts of the mountains and coastal plain.
