As colder air moves in and temps fall below freezing overnight, the scattered rain we’ve had on our Thursday becomes freezing rain – glazing area roads with ice before the peak of the morning commute.
The approximate timeline for the rain/snow changeover starts at 3 am when temps will be low enough at ground level for rain to freeze soon after contact with the pavement. Sleet/ice pellets become the dominant precip type around 6 am. as even more cold air flows in. By 9 am, snow is falling across the region.
Ice amounts of around a tenth of an inch aren’t enough to weigh down power lines and cause power outages, but will spell trouble for numerous vehicles attempting to travel during the Friday morning commute.
Snow amounts are likely to be in the 1″-3″ range region-wide, as the snow tapers off during the afternoon, potentially lingering into the evening for areas southeast of Fort Wayne.
