Weekend Weather Outlook

Cooler air will bring relief to a large portion of the Eastern U.S. this weekend, as storms continue to pummel the Plains and Southeast. 

Saturday

The Midwest, Great Lakes, and Northeast will continue to feel the cooling effects of an upper-level disturbance over the Great Lakes. On Saturday, the cold front associated with this system will advance south out of the Mid-South and Mid-Atlantic and into the Southern Tier. With pleasant weather in the Great Lakes and Northeast, the humidity and temperature will start to drop from Arkansas eastward to North Carolina. 

Areas along and south of this cold front will see showers and storms. Storms may feature damaging winds and localized flash flooding. The heaviest of rain will occur along and close to the Atlantic coasts of South Carolina and Georgia.  

Strong storms will fire off the Rockies and move into the Plains. These will mostly stay contained to the High Plains, but a couple organized lines of storms may trek into the lower elevation portions of the Plains. Large hail and the threat of severe wind gusts are possible. 

The northern Rockies and Pacific Northwest will see multiple opportunities during the day to score on some showers and storms. Localized urban flooding and a few big gusts can be expected. 

It’s expected that all of the Great Lakes, Northeast, Midwest, and Ohio Valley will be dry with pleasant temperatures, especially for an early August day. 

The Desert Southwest, southern Great Basin, central to southern Pacific Coast, and western Four Corners will be dry. 

The high terrain of the Rockies and Appalachians will see 50s and 60s. Seventies will exist in a large portion of the country, including the Northeast, Ohio Valley, Mid-Atlantic, Midwest, northern Plains, and along the West Coast. The Mid-South, Southeast, Gulf Coast, central Plains, northern Great Basin and Pacific Northwest will see 80s. The southern Plains and Four Corners will be seeing 90s. Once again, triple digits will occupy the Desert Southwest and southern Texas. A few 110s are not out of the question in southwest Arizona and southeast California. 

Sunday 

A cold front pushing southward in the Eastern U.S. will lose its steam on Sunday as it pushes into the Gulf Coast. However, it will help drop temperatures and humidity into northern Georgia and South Carolina. The unfortunate factor for this sector of the country is that it will be wet and stormy for much of the Gulf Coast, Tennessee Valley, and southern portions of the Southeast. Flash flooding will be the main concern to watch with this activity. 

Areas north of this front will continue to see pleasant temperatures and humidity values as well as very low chances for rain. This includes the Mid-Atlantic, Northeast, Great Lakes, Midwest, and Ohio Valley. The western portions of the Midwest and the Upper Northeast will have the chance for showers, but neither will have a guarantee to see anything. 

The entirety of the Plains will have the chance for isolated storms. Damaging winds and large hail will be the main risks. 

The northern Rockies and Plains will see showers with a few storms during the day and into the early evening. Damaging winds will be of the greatest concern. 

For the most part, the West Coast states will be dry as well as Nevada, Utah, and Arizona. 

Highs in the 60s will be seen in the higher terrain of the Rockies, Sierra Nevada, and Appalachians. Seventies are a sure bet in the northern Plains, Midwest, and coastal Pacific Northwest. A mix of 70s and 80s will be in for the Northeast, Mid-Atlantic, central to southern Plains, Ohio Valley, Mid-South, and Southeast. The Great Basin, Four Corners, southern Plains, western Gulf Coast, and interior Pacific Northwest will see 90s. Hot 100s are expected in the portions of Texas and the Desert Southwest.
