The first wave of snow Sunday afternoon brought nothing more than a dusting in spots. As the second wave moves through overnight, cold air pushing down from the north will deflect most of the storm's energy to our south across Maryland and Delaware. Additional accumulating snow will likely only stretch into our southern tier counties, while those traveling south of PA could see well over 6" of snow.
Arctic air wins the battle, and for once work in favor of those ready to turn the page to Spring. Due to a tough northerly breeze, most of the storm will miss Central PA. Any additional accumulation toward the Mason Dixon Line would occur in the overnight hours and move out shortly after dawn. There will be a narrow strip of 3-6" south of York & Lancaster Cities. Anywhere north of that line will fade quickly from 3", down to just a few flurries.
Expect clearing skies into Monday afternoon with that northerly wind keeping temperatures in the lower 20s. That will be very cold for March, but those layering up should remember that the same cold air prevented another widespread snowfall from hitting the Commonwealth.
Look for chilly conditions through the rest of the week.
