Discussion

High pressure will control the weather to begin the week, but then a strong cool front will usher the coolest air of the season so far as the overall “step-down” process to colder conditions continues. The upper level pattern is evolving to a chilly one for the Great Lakes, Midwest and Northeast US with high pressure ridging developing along the west coast and a deep trough of low pressure to be centered near the Great Lakes. The combination of these two features will frequently push chilly air masses into the northern US from central Canada over the next couple of weeks and the chilly air will be quite able to spread eastward to the eastern seaboard. The strong cool front that ushers in this significant change to chilly weather will likely generate some shower activity around here late Tuesday night and early Wednesday.
