Heat to Bulge Into Ohio Valley, Northeast US This Weekend

While dangerous heat will hold in the South, a dose of hot and humid conditions will reach the Ohio Valley and Northeast this weekend and into next week.

A large and strong area of high pressure anchored over the South Central states will bulge enough to send near-90-degree Fahrenheit air northward.

The combination of heat, high humidity, sunshine and light winds could pose problems for those partaking in extended strenuous physical activity and those with respiratory problems.

While moist ground and thunderstorm activity may prevent the actual temperature from actually reaching 90 F in some locations, AccuWeather RealFeel® Temperatures will reach triple digits for several hours during the late morning and afternoon hours from Cincinnati to Pittsburgh, Philadelphia, Baltimore, New York City, Washington, D.C., and Albany, New York.

Much of New England will stop short of 90. However, highs will reach or exceed 80 in many areas with RealFeel Temperatures well into the 80s and middle 90s.

The warmth will allow some people to hit the beach or hang out at the pool.

The only deterrent to non-strenuous outdoor activity will be the threat for thunderstorms.

The bulk of the storms will occur north of Tennessee and North Carolina as well as over Florida, with a few exceptions.

In much of the Southeast states, actual temperatures will not be quite as extreme as that of the second half of June. However, the combination of actual temperatures reaching well into the 90s, high humidity, little wind and strong mid-July sunshine will push RealFeel Temperatures to well over 100.

Cities in the Southeast set to broil into next week include Atlanta; Nashville; Birmingham, Alabama; Charlotte, North Carolina; Columbia; South Carolina; and Richmond, Virginia.

The sweltering heat will continue to build in the South Central states as well with no relief in sight. The once moist ground that prevented extreme temperatures during June and early July is drying out. More of the sun's energy will heat the ground and air, instead of evaporating the moisture. Actual high temperatures will be close to 100 with RealFeel Temperatures topping 110 in many areas through next week.

Over the next several days the Dallas/Fort Worth Metroplex is likely to reach 100 for the first time this year and could do so on multiple dates. There have only been a handful of years where the temperature has not hit 100 in Dallas since the late 1800s.
