Mother Nature is delivering back to back punches over the next couple of days. Ice Storm Warnings, Winter Storm Watches and Advisories have been issued for most Pennsylvania counties. The first punch Mother Nature will bring will be in the form of a wintry mix, mainly in the form of sleet and freezing rain during the day tomorrow. The second punch will be snow, beginning late tomorrow night and lasting through the entire day Monday for some areas.
It is strongly encouraged to avoid traveling across Pennsylvania tomorrow. The freezing rain will lead to treacherous travel across much of the state, with even the potential of power outages.
Precipitation will arrive during the mid-morning hours from west to east. Precipitation may start off as brief snow/sleet mix, but will quickly transition to freezing rain across the mountains of the Laurel Highlands and much of central PA. Below is a look at 7:00 AM tomorrow morning.
The freezing rain will arrive for eastern PA areas by the early afternoon. For eastern PA, the worst of the freezing rain will occur during the early and mid-afternoon hours. Areas across northeast PA will have the best chance to see accumulating snow Sunday afternoon, but these areas will also change to a mix of sleet and freezing rain later in the afternoon. Below is a look at 1:00 PM Sunday afternoon:
Precipitation will begin change to snow across eastern PA by sunrise Monday. The snow will fall at varying rates across eastern and northern PA Monday. Elsewhere, we expect any snow that does fall, to be on the lighter side. Below is a look at 10:00 AM Monday:
As we move into early Monday afternoon, the bands of snow will begin to rotate across much of northern PA and all of eastern PA. Below is a look at 1:00 PM Monday afternoon.
This will be a long duration storm. Snow will continue to fall throughout the day Monday and into the nighttime hours for eastern PA, especially for far northeast PA. Below is a look at 10:00 PM Monday night.
Snow showers will continue to fly into the early parts of Tuesday morning and will taper off by the time most of us wake up Tuesday morning.
