A #WinterWeatherAdvisory has been issued for the Lower Susquehanna Valley from 4 AM to 4 PM Wednesday. Snow should overspread the region from west-to-east between 8-11 AM and then changeover to sleet and eventually plain rain from south-to-north..
I don’t expect any accumulations south of the MD Line (precip starts as rain or sleet there). Between the MD Line and PA Turnpike (east of Route 15), a coating to 1” is most likely with 1-3” expected north of the Turnpike and west of Route 15..
Up to 4” is possible in the higher elevations of Perry and northern Dauphin Counties. Precip should change over to plain rain by midday south of Route 30 and by 2-3 PM in northern parts of the Valley. With temps near or above freezing, main roads should generally be wet..
.. but secondary roads could turn slushy and even snow-packed, esp north of the Turnpike. Allow extra travel time tomorrow, drive within the speed limit, and increase following distance. I expect @millersvilleu to finally receive measurable snow but no more than 1 inch..
