Synopsis: Mid-level low pressure is forecast to lift out of the eastern contiguous U.S. (CONUS) at the start of week-2. While most of the associated precipitation is forecast to occur during the late week-1 timeframe, some lingering rainfall may persist into the start of week-2 across the Florida Peninsula. On the backside of the mid-level low, high winds are possible across portions of the Great Lakes and Northeast early in the period, with an elevated potential for Lake Effect Snow over some areas. Later in week-2, mid-level high pressure is forecast to bring more tranquil weather to the central and eastern CONUS. Models depict differing pattern evolutions across western North America resulting in a less confident forecast, with the best agreement over southeastern Alaska where strong onshore flow and resultant episodes of heavy precipitation and high winds remain favored.
