Looking at the long range models for the next 10 days it does not look as if there will be any major differences when it comes to the oppressive heat that has been sweltering the mid-atlantic, Southeast and Northeast. There will be occasional periods of relief but nothing really to write home about.
The Coolest days as it appears right now will come about between August 11-12 From DC North. Now when it comes to New England temperatures seem like they will be some of the coolest in the nation there. However if you are elsewhere the temperatures will be in the 90’s and 100’s. The pattern so far this Summer has been stable. And for the next week to two weeks while you may see a brief spell in the humidity it looks as if the heat is here to stay.
*Note: On the final run of the GFS model (18Z) I noticed that there was a trough of some much cooler air beginning to spill down from Canada at the very end of the run. (For the GFS when its in LA LA land). However none of its other model runs support this thought right now. So for the time being we will go with the thought that this model is an outlier on that. We will keep an eye on that as we typically do.
