Weekend Weather Outlook
UPDATED 7:45 AM EDT, May 4, 2013

A strong but slow-moving storm system swirling across the nation`s midsection will be the root cause for canceling weekend outdoor plans from the Southeast into the Mississippi and Tennessee valleys. The only other weather hiccup will be a few spotty showers in the West.

As if large stretches of the Mississippi and Tennessee valleys need more rain, the same storm system that hammered the region late in the work week will be responsible for more downpours today.
One to 4 inches could soak places like Paducah, Ky., Nashville, Tenn., Atlanta and Jacksonville, Fla. Showers will be more scattered from the Mid-South into the Minnesota Arrowhead. The day could even begin with a light snow accumulation before changing to rain in northwestern Arkansas and southwestern Missouri.
A weaker low pressure area will spin into California, bringing a few splashes of rain from the Sierra into the Rockies. Otherwise, the Plains, Ohio Valley, Mid-Atlantic and Northeast will enjoy sunshine.
The California valleys and Southwest will heat up into the 90s with a few triple digits sneaking into the deserts. Widespread 70s and 80s will rule the Interstate 5 corridor, Deep South and Great Lakes to Northeast.
Cooler 50s and 60s will be found from the Great Basin through the Plains to the Mississippi and Tennessee valleys. The highest Rocky peaks, Upper Mississippi Valley and Mid-South will struggle to reach the 50s.
The weekend will end similarly to how it began across the U.S. The stubborn storm in the Mississippi Valley will only slowly meander into the Southeast. The heaviest band of rain will set up from the southern Appalachians into the eastern Tennessee Valley. Surrounding this zone will be scattered showers from the Missouri Valley to the eastern Gulf Coast.
A few more spits of rain will cause windshield wipers to be needed on intermittent speed in northern California, the Northwest and across the Rockies.
Spring fever will live up to its name again in the Plains, Great Lakes, Mid-Atlantic and Northeast. Here, sunshine and light wind will make for ideal outdoor weather.
Much of the U.S. will be dominated by seasonable temperatures. Highs will surge into the 70s along the West Coast with toasty 90s in the California valleys and Southwest. Other than 50sin the Rockies and parts of the Southeast, 60s, 70s and 80s will be widespread from the Great Basin to the Northeast.
