The eastern half of the nation saw another chilly day on Friday.

Precipitation ended for the Southeast on Friday as a frontal boundary finally pushed offshore and into the Atlantic Ocean. This allowed for high pressure to build in and dry conditions to return.

However, chilly conditions persisted as flow from the north brought cooler air into the region. Highs ranged in the upper 20s in the Northeast, to the upper 30s to lower 40s in the Mid-Atlantic states. Flooding remained a concern for the Lower Mississippi River Valley as the region starts to dry out from the heavy rainfall that affected the Southeast for over a week.

Meanwhile to the north, a trough of low pressure dipped into the northern states from central Canada and pushed a warm front over the Upper Midwest. This system kicked up periods of moderate to heavy show showers as it moved eastward and over the Great Lakes throughout the day.

Snowfall accumulation ranged from 3 to 5 inches from northern and central Minnesota, across most of Wisconsin, and into Michigan. While this warm front triggered snow showers, it brought warmer air in from the south, allowing for high temperatures to return to the lower 20s for the region.

In the West, a warming trend persisted for the West Coast as high pressure strengthened and flow from the north weakened. This allowed for sunny skies and highs to return to the lower 60s to mid-70s..
