Discussion
Temperatures for the rest of week will moderate some compared to the recent chill, but they’ll still be primarily below-normal for this time of year. Another serious shot of cold air looks likely to arrive in the Mid-Atlantic region by Sunday of the upcoming weekend and it appears that this overall colder-than-normal weather pattern will continue right through much of next week. The weekend Arctic blast is likely to result in an impressive “lake-effect” snow event for those areas in and around the still relatively warm Great Lakes. As cold Arctic air flows over the warmer waters of the Great Lakes, the lower atmosphere tends to destabilize and snow showers/squalls are likely to be the outcome in the typical “lake-effect” region of the Northeast US and Great Lakes – perhaps a snow shower can even make it into the I-95 corridor. Abnormal high pressure will settle into northern Canada by later in the weekend and this type of “high-latitude blocking” pattern will likely help to sustain the colder-than-normal conditions around here right through most or all of Thanksgiving week with a reinforcing shot of Arctic air possible just before Turkey Day.
