Weather Summary

Weather Underground Forecast for Wednesday, May 23, 2012.

The Nation will continue to see relatively stagnant weather on Wednesday as afternoon thunderstorms develop in the East and the Northwest continues to see cool, wet weather.

The Northeast will see another day of afternoon showers and thunderstorms as the disorganized frontal boundaries that have been lingering around for the last few days continue their snails pace drift eastward. Thunderstorms are anticipated from the Carolinas through coastal Maine, with the bulk of precipitation expected in the southern Appalachians.

Further south, wet weather should end on Wednesday, with clear skies building into the Gulf Coast states.

Clear skies are also anticipated throughout the Plains, but the Northern Plains will see cloud cover move in as some rain approaches from the West. The precipitation will be most pronounced over the Dakotas in the morning, then into Minnesota by afternoon.

Further west Precipitation will increase a bit in coverage as moisture streams into the Northwest. Most of Washington, Oregon and Idaho will see Precipitation on Wednesday.

The nation’s biggest weather shift will come to Florida, where heavy rain will move into southern portions of the state as moisture associated with the remains of Tropical Storm Alberto rain themselves out across the western Atlantic.
