After many locations over the Plains feel like late summer this weekend, the record-challenging warmth will expand to the Northeast next week.
Millions of people will be reaching for shorts and short-sleeves for a few days as the warmth builds.
High pressure over the South is forecast to continue to pump warm air in from Mexico and provide abundant sunshine to Texas and the Plains this weekend. Some major cities will challenge record highs as a result, including Dallas, Denver, Oklahoma City and Kansas City, Missouri.
According to AccuWeather.com Senior Meteorologist Paul Walker, "Temperatures across the Plains will feel more typical of Labor Day than late October."
Temperatures will run between 10-15 degrees F above average as far north as North Dakota.
On Sunday, high temperatures will reach the 80s as far north as northern Nebraska while highs will climb into the 90s over parts of Oklahoma and Texas.
"The dome of high pressure will be pushed southward as a storm system moves over the West Coast. Cooler air will move in early next week but the heat will continue over southern Texas," Walker said.
As heat holds over southern Texas, warmth will surge northeastward early next week. Summerlike temperatures are in store across the Ohio Valley into the East Coast. More record-breaking high temperatures are possible.
Many areas from New England to the mid-Atlantic and Southeastern states will record temperatures 10-20 degrees above average.
Remember to stay hydrated when engaging in strenuous outdoor activities, such as exercise or manual labor.
From a safety standpoint, temperature in automobiles on a sunny, warm day in the autumn can still reach dangerous levels.
Never leave a child or pets in a vehicle, for any length of time as a result.
On Tuesday, Oct. 21, 2014, an infant died after being left in a vehicle in Tucson, Arizona. The high in Tucson on Tuesday was 86 degrees.
