Title: Polar Vortex in the Summer?

We all heard a lot about the so called polar vortex during the course of this past winter as very cold air from the polar regions visited many areas of the U.S. last winter. For many folks in the Great Lakes and Upper Midwest, the summer version of the polar vortex may visit early next week as a shot of unseasonably cold air will move into those areas by the start of next week.

Temperatures will fall well below normal across the eastern areas of the Northern Plains and Great Lakes next week. Some of that colder air will spill south into the Corn Belt and then east into New England by late next week.

With this cold shot coming and the fact that we will be half way through July it certainly appears that if we are going to get any real hot weather this summer it will have to happen in late July and into August before the summer season winds down. All indications suggest that other than in portions of the southeast and south central areas of the U.S., August will likely continue with the same trends we are seeing here in July. This all means that areas that have trended toward near normal or cooler than normal temperatures will continue to experience similar weather trends through the rest of July and through August.

Farther west it has been hot across California and portions of the southern Rockies and Great Basin states. We expect that trend to continue, however, the summer monsoon moisture flow is beginning to develop in the Desert Southwest and southern Rockies. Over the past two weeks, those areas have seen an uptick in thunderstorm activity and that trend will continue as we head through the middle to end of July. There are some strong suggestions that rainfall could be heavy and widespread in the coming weeks across the Great Basin, Desert Southwest and Rockies.

Drier conditions, but no severe dryness is expected over the Ohio Valley, eastern Corn Belt and portions of New England.
