Discussion
Temperatures will make a noticeable rebound today from yesterday’s chilly conditions and should make it into the middle 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 middle 30's. 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 snow and/or ice at the onset with minor accumulations. A cold, windy and dry day is setting up for Sunday to follow the wintry mess to start the weekend.
