Traveling Back in Time

The Winter Storm Event on January 30th, 2010...

With a potent winter storm on the way Sunday, I thought it would be the perfect time to look back and reflect on the winter storm event that occurred exactly 11 years ago on January 30th, 2010. This particular storm caused major headaches across parts of the Eastern Shore, Delaware, and southern New Jersey-where numerous traffic accidents and scattered power outages occurred due to the plowable snowfall.

A low-pressure system developed along the Gulf Coast on Friday, the 29th and traveled northeast just off the North Carolina coast. There was plenty of arctic air in place that Saturday morning which set the stage for widespread snow to develop just before 10 a.m. and it lingered throughout the day across eastern parts of the Mid-Atlantic. Winter Storm Warnings went into effect for Kent, Queen Anne's, Caroline, and Talbot counties at 4:16 a.m. Saturday and then the National Weather Service expanded the warning to include Cecil county at 5 p.m. that evening. Snowfall totals of 5"-nearly a foot were found across the Maryland Eastern Shore, Delaware, and southern New Jersey. Take a look at some of the snowfall numbers recorded in Maryland...


Eventually, the low pulled farther away from the coastline and out towards the middle of the Atlantic Ocean Saturday night, putting an end to the wintry weather.

There was a very sharp snow/no snow line across southern Pennsylvania which led to drastic differences in snowfall totals across the region. With this upcoming winter storm Sunday-Tuesday, the freezing rain/sleet/rain mix will occur Sunday night-Monday afternoon, which will lead to a wide range of snowfall totals across the state due to some mixing and melting upstairs in the atmosphere. Areas around the city-northward have the better shot of seeing higher snowfall amounts, whereas the warmer nose of this system will edge in from the southwest, ultimately bringing more of an icy mix/rain showers across far southern Maryland for a good portion of Monday. Monday night-Tuesday is when the system will begin to depart offshore...the precipitation type will transition back over to mainly snow across Maryland as the moisture wraps around the low in a counter-clockwise rotation. Lingering flurries will taper off midday Tuesday and the weather pattern will relax and quiet down just in time for the middle of the week.
