Weather Underground Forecast for Monday, April 16, 2012.

Strong storms will move into the Great Lakes and Eastern Valleys on Monday as the storm system in Nebraska begins to weaken and lift northeastward across the Upper Great Lakes and into southeastern Canada. As the system progresses, expect moderate to heavy rain and snow showers to continue on the northern edge of this system and ahead of an associated warm front, from areas of Minnesota through northern Wisconsin and northern Michigan. To the south of this activity, showers and thunderstorms ahead of the northern half of an associated cold front will be more scattered in nature as the boundary moves through the Ohio and Tennessee Valleys. Precipitation and storms will then ramp back up in the late afternoon and evening as storms reach into the eastern Ohio Valley and Northern Appalachians. There is a slight risk for severe thunderstorms with large hail and possible damaging wind gusts in eastern Ohio, western Virginia, western Pennsylvania, and western and northern New York .Further south, abundant Gulf moisture will maintain heavier rainfall along and ahead of the southern half of this cold front, from the coastal areas of Texas and Louisiana into portions of the Southeast.

Further East, many areas along the East Coast will experience well above normal temperatures on Monday. New England and parts of the upper Mid-Atlantic will experience the warmest temperatures with highs reaching into the mid- to upper 80s and even lower 90s in some areas. Expect a cooling trend to reach the region by Tuesday.

Finally out West, a cold front reaches northwestern California and the Pacific Northwest with rain. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 8 degrees at Wolf Creek Pass, Colo. to a high of 97 degrees at Kingsville NAS, Texas
