Stifling heat, humidity to follow Barry in southern US
July 16, 2019; 9:58 AM
In the wake of Barry's rain and flooding, a broad area of heat and high humidity will take hold over much of the southern and central United States for the balance of this week.
Barry deposited up to 23.43 inches of rain on Louisiana, delivered over 12 inches of rain in parts of Mississippi and was responsible for extensive urban and low-lying area and coastal flooding, power outages and property damage. Two people lost their lives in rough surf in the Gulf of Mexico related to Barry.
Barry brought flooding downpours to parts of southern Arkansas on Tuesday.
However, most areas are likely to miss the widely separated thunderstorms that pop up in intense southern July sunshine each afternoon and evening from Wednesday through Saturday. The exception can be from southern Missouri into northeastern Arkansas and Tennessee on Wednesday.
While the heat is not uncommon for this part of the nation during the middle of July and in the wake of a tropical storm, it can add to the difficulty of cleanup operations for those dealing with mud, fallen trees and power outages in portions of Louisiana and Mississippi.

Now that Barry has come and gone, what's in store for the next few weeks?
"As temperatures climb into the 90s F during the afternoon hours, AccuWeather RealFeel® Temperatures will surge past 100 each day into this weekend," according to AccuWeather Senior Meteorologist Brett Anderson.
And heat is ramping up across much of the country beyond the southern region, including up into the Northeast.
An AccuWeather analysis estimates more than 135 million Americans will experience AccuWeather RealFeel Temperatures above 100 degrees Wednesday or Thursday, covering 29 states from New York to Arizona. The AccuWeather RealFeel Temperature Guide advises caution at those temperatures and warns of dehydration, heatstroke, heat exhaustion and heat cramps if outside for extended periods.
Even long-time southern residents are urged to take breaks from strenuous physical activity and stay hydrated.
The weather will provide an opportunity to take a break at the beach, but beach goers should still take caution when going for a dip. Seas and surf have diminished over the Gulf of Mexico. However, rip currents are always present due to the ever-changing tides.
There are no signs of any organized tropical systems for the Gulf of Mexico into next week, even though a storm at the jet stream level of the atmosphere may form over the central Gulf coast later this weekend.
However, while similar to the setup that gave birth to Barry, this upper-level storm is likely to be much weaker and therefore much less likely to spin down to the surface.
An uptick in shower and thunderstorm activity is likely over the Deep South due to slightly cooler air aloft associated with the slight southward dip in the jet stream starting on Sunday.
