The north-central U.S. will see a pattern of robust storms settle in for the weekend. Temperatures will be a blaze in the south-central U.S. as summer rages on.
Saturday
Strong storms will belong to the Midwest, Great Lakes, and central to northern Plains. Sporadic flash flooding and a couple lines of severe wind gusts will be the main threats. The heaviest rain will fall from South Dakota eastward through Minnesota, Wisconsin, and Michigan. Late in the night a few strong storms may form in western North Dakota, eastern Montana, and northeast Wyoming, but confidence is low.
Periods of steady rain and showers will be in place for the Pacific Northwest. Light to moderate rainfall accumulations are expected in northern California, Oregon, Washington, and northern Idaho.
Another day of showers and storms are likely in the Rockies, eastern Great Basin, and Four Corners. This will bring much needed rain with localized pockets of flash flooding possible.
The Southeast, Mid-Atlantic, Northeast, and along the Gulf Coast will see isolated storms. Flash flooding is the main threat to watch.
During the day, a couple of isolated showers and storms are possible in the Lower Midwest, Mid-South, and Ohio Valley. The northern sections of the Midwest and Ohio Valley have a greater chance of seeing significant storms late in the night. However, most of these places will remain dry.
The Desert Southwest will be hot and dry once again.
Highs in the 50s are likely in the higher terrain of the Cascades and Rockies. Along the Pacific Northwest coastline and western Washington and Oregon will see a mix of 60s and 70s. The Upper Midwest, and central to southern West Coast will feel 70s. Temperatures in the 80s will be found in the Northeast, Mid-Atlantic, Southeast, northern Plains, Four Corners, central to northern Great Basin, and along the Gulf Coast.
Nineties will be common in the Mid-South, Ohio Valley, central Plains, southern Plains, and southern Great Basin. Another day of 100s will torch the Desert Southwest as well as far southern Texas.
Sunday
Scattered thunderstorms will erupt in the Plains on Sunday. Storms will be present in New Mexico, western Texas, Oklahoma, Kansas, and Colorado but will not be the strongest the
Plains have to offer. Nebraska, eastern Wyoming, South Dakota, Iowa, and western portions of the Midwest will see the more robust storms. Large hail and damaging winds will be the threats to watch for.
Looking to the east, a cold front will slowly push to the SE across the Ohio Valley, northern Mid-Atlantic, and Northeast. Gusty storms are likely south of this cold front with damaging winds being the main threat.
Showers and storms will be plentiful in the Rockies and Cascades. Northern California, Oregon, Idaho, Montana, Wyoming, Utah, Colorado and western New Mexico are where to expect this activity. Light to moderate rainfall accumulations is expected.
Hit and miss thunderstorms will be found in the Southeast, Mid-South, and along the Gulf Coast. Some places will see no rain while others could get ample amounts of rain.
The Great Basin, Desert Southwest, and West Coast will be dry on Sunday.
Temperatures in the 50s and 60s will be seen in the higher terrain of the Rockies, Cascades, and Sierra Nevada. Seventies will be found in the Upper Midwest, northern Plains, Pacific Northwest, and along the West Coast. The Northeast, Mid-Atlantic, Ohio Valley, Southeast, Four Corners, Great Basin will see a healthy mix of 80s and 90s. Solidly in the 90s will include the Mid-South, central Plains, Midwest, and southern Plains. The Desert Southwest will see its daily run of 100s continue.
