Unsettled weather continues in the East on Monday as a strong cold front pushing across the Eastern Valleys reaches the Eastern Seaboard. Deep moisture accompanying this system will kick up bands of moderate to heavy rain and areas of thunderstorms across the Southeast and southern Mid-Atlantic, while lighter showers spread across New England. Rainfall totals from this disturbance may surpass two inches in isolated areas of the Southeast and southern Mid-Atlantic. Minor flooding and areas of flash flooding will likely become a concern for these areas as many streams and creeks experience high flows. Showers in the Northeast are expected to taper off by Monday evening as the northern edge of the cold front moves offshore into the western Atlantic Ocean.
Meanwhile, much of the Northeast and northern Mid-Atlantic will experience one more day of unseasonably warm weather before a cold northwesterly flow sets up across the region and lowers daytime highs by Tuesday.
Behind this disturbance, high pressure prevails across the Midwest, allowing much of the region to experience closer to normal temperatures and dry conditions. In the North, a disturbance passing across the northern Upper Great Lakes will kick up a few lake-effect snow showers in Michigan 1/4's Upper Peninsula.
In the West, a clipper setting up in western Canada will bring moderate snow showers to the Northern Rockies. Elsewhere, snow showers are expected in parts of the Central and Southern Rockies, while chilly, below normal temperatures continue across the West. Temperatures in the Lower 48 states Sunday have ranged from a morning low of -38 degrees at West Yellowstone, Mont. to a high of 90 degrees at Corpus Christi NAS, Texas
