Refreshing Change Ahead For Storm-Weary Midwest as Severe Weather Threat Shifts Southeast

Published: July 28,2017

A welcome change in the weather pattern will arrive in the storm-weary Midwest late this week as the threat for severe thunderstorms shifts toward the eastern states.
Currently, a low-pressure system is bringing rain and thunderstorms to parts of the Tennessee and Lower Mississippi valleys.

Current Radar, Watches and Warnings
Overnight Thursday into Friday morning, flooding was reported in portions of Missouri and Indiana, including in Johnson county in Missouri where numerous roads were closed.

Severe Storms and Rain Shift East

Heat and humidity has surged back into parts of the East ahead of a cold front.
Friday evening, the cold front will sag southward, and the chance of severe thunderstorms will stretch from the Carolinas and eastern Georgia into the mid-Atlantic, with damaging wind gusts the primary concern.

Friday's Thunderstorm Forecast
Localized flash flooding will also be a concern, especially in areas that have been saturated by heavy rain in recent weeks. That said, the overall progressive nature of the front may help to keep rainfall from becoming excessive.

A Welcome Change to End July

The front will continue to push farther south and east into this weekend, and that's where the good news comes into play.
A cold front will usher in lower humidity throughout the Midwest and parts of the South and East late week into this weekend.
Lower humidity will engulf the Ohio Valley on Friday, kicking off a stretch of mainly dry weather that will continue through the weekend and possibly into early next week.
Meanwhile, parts of the East and South will see scattered showers and thunderstorms into Saturday. An isolated severe storm cannot be ruled out, and locally heavy rain is also a concern.
The front will likely continue to scour out moisture through late week and this weekend across the East. Decreased humidity levels are also possible across much of the South by late this weekend.

Temperatures will be near or below average in the eastern third of the nation into the weekend.
Relatively mild temperatures may continue into the start of August, as well, due to an overall southward dip in the jet stream across the East. NOAA's Climate Prediction Center is forecasting the highest probability of below-average temperatures to be in parts of the South and Plains in their latest 6- to 10-day outlook which includes the first few days of August.
