A recent push of autumnlike air from the Midwest to the East and part of the South has some folks wondering if the sun has yielded its last stretch of summer heat.
Regardless of how temperatures behave, summer does not officially end until Sept. 22. Meteorological summer comes to a close in early September, and solar summer winds down in early August.
However, what does the weather in August have in store based on seasonal changes, meshed with the month's unique forecast weather patterns? Will the back-and-forth extremes continue in the Midwest and Northeast? Will the heat and drought continue in the West?
Our long-range forecasting experts, headed by Meteorologist Paul Pastelok, "summarize" below:
"Cool weather will continue in the Northeast into the first week of August," Pastelok said, "But, very warm and humid weather is likely to return during weeks two and three."
That will mean plenty of good days at the beach and in the mountains through the end of the month.
A lower sun angle and lengthening nights may take the edge off the heat somewhat, so that it should not feel quite as extreme as the mid-July heat wave.
AccuWeather.com RealFeel® temperatures peaked well above 100 degrees in many areas for multiple days. In some cases, it felt hotter than 110 degrees. For cool weather lovers and those in poor health, the nights were unbearable without air conditioning.
The re-building warmth toward mid-August will likely bring another surge in energy demands.
In New York City, energy demand was generally higher at night during the mid-July heat wave than when it was most days last week. While longer nights during August may counteract some of the energy demand later this month, a return of high humidity may still make the nights warmer than average.
"The northern and central Plains to the Midwest have a chance at significant, persistent cool weather during August," Pastelok said, "Position and magnitude of a southward dip in steering winds will determine how extensive that cool pocket is for the Midwest and if it could continue to reach part of the Northeast or back off."
The Southeast can expect an extension of the mild June and and July conditions into August.
"Much of the Southeast will remain generally wet with temperatures averaging near to slightly cooler than normal, but there may not be as many days with rain from the Gulf Coast to New England, compared to earlier in the summer," Pastelok stated.
According to Long-Range Meteorologist Mark Paquette, "Dorian is one possible system to watch for rainfall impact in the Southeast, but with high pressure set up the way we think it will be during August, the door is open for a Gulf of Mexico tropical system impact during the month."
In much of the West, heat will fire up toward the middle of the month causing demands for energy to rise.
Look for showers and thunderstorms affecting the Southwest to expand northward toward the northern Rockies and Snake River Basin during August.
According to Western Weather Expert Ken Clark, "The monsoon showers and thunderstorms will continue to make some small dents in the drought, but only at a very local level and not for a long-term perspective."
"Later in the month, we expect the isolated downpours to begin to diminish in the Southwest," Pastelok added, "But central and coastal Texas may begin to receive showers and storms more often."
Much of California will be dry, except for spotty storms mainly over the Sierra Nevada.
As a result of the diminishing showers and thunderstorms in the Southwest, as well as drying vegetation, the threat of wildfires will continue.
"In the Northwest, the dry weather may wind down a little earlier earlier than average with the chance of some coastal rainfall later in the month," according to Pastelok.
So, is summer over?
Even in parts of the Midwest, where cool air may be a frequent visitor, there will still be some warm days. In the South, temperature departures will be so slight that there will be plenty of sufficiently warm days to call it summer. The Northeast will experience a return of heat and humidity. Plenty of hot weather is in store for the West with the cool spots being the high country and the immediate Pacific coast.
Balancing out the extent of temperature extremes, the heavily populated Northeast and its thirst for keeping cool may drive energy demands through much of August.
According to the U.S. Energy Information Administration, in 2012, about 68 percent of the electricity generated in the nation was from fossil fuels (coal, natural gas and petroleum).
