DAYS 1-5 (JANUARY 1-5)
Happy New Year to all! It’s 2020 now and on we go with the outlook for the weather for the first several days of the second month of meteorological winter. And the pattern is an active one to start off the year as we have a fairly fast west to east flow across the USA. First, a drying westerly breeze will bring a nice beginning to the year in contrast to the messy storm that ended 2019. Other than some patchy icy areas on the ground this morning, expect good weather for your New Year’s Day walk or any other travel you need / want to do. High pressure will move across the region Thursday with another nice day, but things quickly turn after that when we have an initial low pressure area tracking northeastward from the Ohio Valley into the eastern Great Lakes Friday into Saturday, then redeveloping just south of New England later Saturday and passing over or just south of the region early Sunday. This will bring a stretch of unsettled weather in the form of periods of rain arriving Friday, continuing Saturday, but possibly ending as snow or snow showers Sunday as colder air arrives. It’s a little clear how this evolves 4 to 5 days out so it needs to be closely monitored, as subtle differences in timing and placement of the secondary low pressure system can mean the difference between a few snow showers and us having to reach for the shovels…
