Title: Up and Down Temperatures

The Midwest and East Coast suffered through the worst heat and humidity of the season over the past week before cooler temperatures and rain rolled into those areas early this week bringing relief. While the heat and humidity were oppressive, the recent turn to cooler temperatures is an indication that any heat waves that develop this summer will be short lived.

With a large high-pressure system developing in the west, cooler temperatures and better rain chances will move into the central and eastern areas of the USA as the jet stream takes a dip into the Great Lakes and east. As you can see in the graphic below a large high is building into the Rockies. This will bring monsoonal moisture and thunderstorms into the Desert Southwest and Central Rockies.

As cooler air descends south into the Great Lakes and spreads south and east, relief from the recent heat wave will move into the southeast states and East Coast. Falling temperatures and rainfall will move south and east into the eastern half of the nation.

                After some cooler temperatures in the west this past weekend, temperatures will be on the rise over the Rockies and Plains.
