July and indeed summer 2017 so far as been pretty warm Out West with persistent heat while it’s been a mixed or back and forth kind of summer further east with cool, wet days and warm to hot.

This is the temperature anomaly across the US thus far in July 2017.

Much of the heat has been focused in the N Rockies and not as much in the Desert Southwest like we saw in June. It was a warm open to July in the Southwest but a north and east shift in ridge positioned has allowed the increase in moisture from Mexico.

August looking quite interesting.

It’s looking et in the interior West which suggests an active monsoon pattern but also cool for the majority except the Northwest and N Rockies where the drought continues to worsen. The CFSv2 indicates a moisture plume stretching from Atlantic westward into Florida, likely hinting at increased tropical activity and I do believe, given the warm water stretching from Gulf and around Florida/off East Coast all the way to Africa, the ridge positioned further north.. we may have tropical dealings for the US during August. Nationwide, heat looks to be less of a factor although local heat, particularly in the drought areas could be a story.

Hurricanes threatening the US could be the biggest story in August.

Here’s the CFSv2 August outlook.
