RealFeel Temps Near 100 Keep the East Sweating This Month

Real feel readings will approach the century mark in the days ahead across the eastern U.S., while the southern and western portions of the nation also continue to sizzle. Here is a look at the steamy forecast ahead.

Dog Days of Summer in Full Swing for Much of the U.S.

The dog days of summer are firmly entrenched across most of the U.S. While the eastern U.S. will at least enjoy some breaks in the heat with a renewed threat of rain and thunderstorms, the western half of the country will continue to see mostly dry conditions.

It has already been a sweltering summer for many of the most populated urban areas of the Northeast. After notching its 29th day with temperatures of 90 degrees or higher, Philadelphia is forecast to see this benchmark several more times through next week.

It will be equally toasty moving to the south along the East Coast. Raleigh, North Carolina, will jump from highs in the low 80s on Tuesday to readings that easily surpass the 90-degree mark all of next week.

Compounding the heat will be the increase in humidity levels across the eastern U.S.  The high humidity will translate to temperatures that are about five to 10 degrees warmer than the actual thermometer. This surge of humidity will also be responsible for the daily threat of thunderstorms.

Forecasters are warning that warmer-than-average overnight lows will limit the relief from the heat. Overnight lows tend to trend warmer when humidity levels are high. Some urban areas on the East Coast may fail to drop below the 80-degree mark at times. The lack of relief from the heat overnight has been linked to higher heat wave mortality rates.

While most of the U.S. will sizzle in the coming days, the Great Lakes and the northern reaches of New England will remain cooler. Less humid air diving down from Canada will keep it comfortable in the Adirondacks of New York and at the popular tourist destination of Saranac Lake. You can expect daytime highs that top out in the 70s through the middle of August in this corner of the country.

The West will also be dealing with high heat, wildfires, and smoky conditions. The western third of the country will see the hottest weather in the U.S. through next week, including widespread temperatures in the triple digits for the Desert Southwest.
