Discussion
Temperatures will make a noticeable rebound today from yesterday’s chilly conditions and should make it into the 50's which is well above normal for mid-January. A strong cold front, however, will cross the region early tomorrow and its passage will usher in a much colder air mass to close out the work week. This Arctic air mass will ride in on strong NW winds later tomorrow and tomorrow night that can gust past 40 mph. Strong high pressure will build across southeastern Canada on Friday and temperatures will struggle here to reach the freezing mark. Low pressure over the Great Lakes region on Saturday will spread precipitation our way and with a cold, dry air mass in place, there can be some accumulating snow at the onset. This is not looking like a major snow event, however, as a changeover to ice and then to rain is anticipated. A cold, windy and dry day is setting up for Sunday to follow the wintry mess on Saturday and Saturday night.
