July was an up and down month with alternating periods of hot and cool covering the whole nation. Despite a couple of heat waves most of the nation experienced near normal temperatures overall in July.
The month of August can sometimes bring the hottest temperatures of the year along with periods of high humidity. The month of August is when we hear about the “Dog Days of Summer”.
The dog days of summer are the hot, humid days of summer. They were historically the period following the heliacal rising of the star system Sirius, which Greek and Roman astrology connected with heat, drought, sudden thunderstorms, lethargy, fever, mad dogs, and bad luck!
While there certainly be some “dog days” in August, overall the temperatures across the USA will be close to normal if not somewhat below normal in some areas. The map below shows the temperature prediction for August. The warmest areas will be along the West Coast and East Coast with the middle of the nation expecting near to below normal temperatures. There will be some periods of hot weather with a heat wave or two, however, prolonged, long last heat is not expected.
Precipitation is likely going to be near to above normal in the same areas that experienced wet conditions in June and July. This will be especially true in the Northern Plains and northwest areas of the Corn Belt and the rest of the Corn Belt.
The weaker than normal monsoon season will keep precipitation below normal in August across the Southern Rockies and Mexico. The southeastern states may also experience below average rainfall in August, especially if no tropical storm or hurricane activity develops.
With near average temperatures and near average or above average precipitation we do not expect any late season drought develop and favorable conditions for crop development.
