Weather Underground Forecast for Tuesday, May 01, 2012. A moderately strong storm will move through the Northeast Tuesday, producing more rain from Ohio through New England. The heaviest of this rain will likely move from Ohio very early in the morning to New York and Massachusetts into the afternoon. By the end of the day, the storm will be far enough off the coast and into the Atlantic Ocean that most of its associated rain will have diminished. The associated cold front will drape across the Appalachians, where it will provide mainly light to moderate rain in Kentucky, West Virginia, and Virginia.
Another storm will move through the Northern Plains and into the Upper Midwest, where it will generate moderate to heavy rain from the Dakotas through the Great Lakes. The Storm Prediction Center has issued a slight chance of severe weather from this storm, which means that severe thunderstorms are possible. Residents in the Dakotas, Minnesota, and Wisconsin should prepare for strong thunderstorms capable of producing large hail, heavy rain, and strong winds. Tornadoes will also be possible, so advanced safety preparations are necessary.
Moist Pacific air will pour into the Northwest, producing mainly light rain from the coast through the Intermountain West. Elsewhere in the West, dry conditions are expected for the Southwest, while coastal clouds along the coast of California signal the beginning of the foggy coast season.
The Southeast will be quite warm with temperatures in the 80s and 90s, while the Southern Plains will see similar temperatures with more cities in the 90s. The Northwest will rise into the 50s, 60s, and 70s, while the Northwest will see temperatures in the 50s and 60s. Temperatures in the Lower 48 states Monday have ranged from a morning low of 12 degrees at Mt. Washington, N.H. to a high of 93 degrees at Perry, Fla.
