AccuWeather experts state at midday Monday that a storm emerging off the coast of the Southeast will produce rain and thunderstorms from the Carolinas through Florida on Tuesday, while a separate storm will spark rain and snow showers in parts of the Upper Midwest and Great Lakes. A third storm is expected to move onshore in the Pacific Northwest, bringing more clouds and showers to parts of the region.
The current National Weather Service outlook for St. Louis for Nov. 6 (tomorrow) is: "Mostly cloudy, with a high near 52. Calm wind becoming southwest 5 to 9 mph in the morning."
Central U.S. Weather for Election Day
There will be a major contrast in the weather across the central United States. Chilly and unsettled weather will impact the Great Lakes region, while dry and warm weather dominates the central and southern Plains.
A weak storm will be moving across Manitoba and western Ontario, bringing rain and snow showers, brisk winds and chilly air to the western Great Lakes.
Voters in Chicago and Grand Rapids may contend with passing rain showers and a chilly breeze with highs being held in the 40s.
Heavier rain showers and some snow mixing in or falling alone may impact eastern Minnesota, the Upper Peninsula of Michigan to northern Wisconsin and northern portions of the Lower Peninsula of Michigan.
Meanwhile, a large dome of high pressure dominating the Southwest will have an influence on dry and warm weather for the central and southern Plains. In the central Plains, highs could climb into the 60s and 70s.
Texas may have highs ranging from the upper 60s and lower 70s around Dallas and Houston to the mid-80s across Deep South Texas. Abundant sunshine should accompany the warm weather in the southern Plains.
Eastern U.S. Weather for Election Day
A storm is expected to emerge off the Southeast Coast of the U.S. on Election Day, potentially sending rain, thunderstorms and wind into coastal areas from Florida through North Carolina.
The rain and wind will then spread up the mid-Atlantic coast Wednesday into Thursday.
For millions of people still recovering from Superstorm Sandy, this is not welcome news. Thousands are projected to still be in the dark through the middle of next week, following Sandy's impact.
"The weather pattern remains volatile for another storm to form on the East Coast, but nothing like Sandy," AccuWeather Expert Senior Meteorologist Henry Margusity said in the release. "A storm that would be more normal for early November."
High pressure dominating eastern Canada is expected to maintain its control. With this pattern, coastal storms have nowhere to go, so they slow down off the East Coast of the U.S. That is a classic nor'easter setup.
It is not out of the question that voters will deal with torrential rainfall and high winds from South Carolina through the northern half of Florida. People heading to the polls in Charleston and Columbia, S.C., Savannah, Ga., and Jacksonville, Fla. will have to brave the heaviest of the rains.
Meanwhile, chilly air will be funneling across the interior Northeast and down the spine of the Appalachians with highs in the 40s and 50s forecast. A few spots of the higher elevations of northern New York and northern New England may be held in the 30s.
Dry weather with temperatures will be in the 60s and 70s is in store for much of the Deep South from Texas to western Alabama.
A zone of showers and thunderstorms will be impacting central Florida as a front will be stretched across the Sunshine State to the south of the aforementioned low. Temperatures south of the front will be mild in the 80s from Orlando to Miami and Key West.
Western U.S. Weathe for Election Day
Clouds will be increasing across much of Washington and Oregon during the morning hours as a storm approaches the Pacific Northwest on Election Day. A few showers will reach western Washington and northwest Oregon by the midday hours. Voters in Seattle will need to reach for umbrellas before heading to the polls, especially the later in the day it gets.
In Southern California and the Desert Southwest, temperatures may actually climb a bit above normal. Los Angeles may rise into the mid-80s, while normal highs for this time of year are in the lower 70s. Phoenix is also forecast to climb into the mid-80s, about 5 degrees above normal.
Dry and mild weather is in store for places such as Salt Lake City, Albuquerque and Denver as well.
