An arctic cold front passed across the region during the early morning hours on February 3 accompanied by a few snow showers. Thereafter, very cold air gradually advected into the region on February 3 into the morning hours on February 4.

Air temperatures gradually fell throughout the day on February 3 with readings falling to 5 to 15 degrees below zero by the early morning hours on February 4.

In addition to the cold, this arctic air mass brought strong winds to the region during the daytime hours on February 3 into the overnight hours before easing on February 4. Peak wind gusts between 30 and 40 mph were observed. These winds resulted in at least some downed tree limbs and branches.
