Discussion
Low pressure will push across southern Canada during the next couple of days in a general “west-to-east” fashion and it’ll strengthen markedly by the time it reaches the Canadian Maritime Provinces late tomorrow. This low pressure system will have a trailing strong cold front that will slide across the I-95 corridor region during the early morning hours on Thursday and its passage will likely not go unnoticed. There can be snow and/or rain showers along the I-95 corridor from later tonight into tomorrow morning and perhaps even a heavier snow squall as the cold front surges towards the coast. Small accumulations are on the table between later tonight and late morning on Thursday and, as a word of caution, the ground is quite cold given the recent temperatures so any snow that does fall – even if only minor amounts - can quickly lead to slippery road conditions.
In addition to the snow and/or rain showers, the winds will become a big factor increasing noticeably later today and tonight from a southwesterly direction and then they are likely to gust to 50 mph or so from a northwesterly direction on Thursday and Thursday night following the passage of the front. These powerful NW winds later tomorrow and tomorrow night will usher in another Arctic air mass and wind chills are likely to reach their lowest levels so far this season.
