Its a very toasty 73 degrees. Yes most guidance at that point and seeing a 600 DM ridge in that spot 9/10 leads to a heat surge even into the NE. But it became apparent the ridge would focus heat just south and west of the area despite one day by the middle of last week. That ridge will move right back into the Rockies seasonal tendencies are strong this season. Will they break into early Sep would be the next question or is the focus on tropics.
