The nation's weather

Weather Underground Forecast for Monday, April 23, 2012.

Wet and unsettled weather conditions will persist in the Mid-Atlantic and Northeast on Monday as a deep Nor'easter along the Mid-Atlantic Coast lifts northward through the Northeast. Strong winds wrapping around this system will draw moisture from the Atlantic Ocean inland, creating light to moderate rain showers in the Upper Mid-Atlantic and southern New England Areas. The New England coastal plains and foothills should expect the heaviest amounts of rainfall through Monday morning as the system drags a frontal boundary across the region with heavy rain at times. Rain will then taper to showers during the evening leaving behind rainfall total ranging from 1 to 3 inches and locally higher amounts. Flood Watches are in effect for these areas an anticipation of Sunday night and Monday rainfall. In addition to rain, a mix of rain and moderate heavy, wet, late-season snow is anticipated across the Lower Great Lakes and Central Appalachians, while freezing rain accompanies morning showers in Maine. Residents are encouraged to prepare for tree damage and possible power outages due to falling power lines from heavy, wet snow accumulation. Snow accumulations in the Lower Great Lakes and Central Appalachians for Monday are expected to range up to 18 inches. Winter Storm Warnings and Winter Weather Advisories are expected to remain in effect for these regions through Tuesday morning.

In the West, expect warm, above-average temperatures to continue throughout much of the inland West as a ridge of high pressure remains the dominant weather feature of the region. By the evening hours a few areas of showers and thunderstorms may develop across the southern Cascades, Sierra Nevadas, and the Northern and Central Rockies. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 18 degrees at Grayling, Mich. to a high of 100 degrees at Palm Springs, Calif.
