In the last 24 hours, model guidance has expanded the shield of heavy snow about 50 miles north, while keeping a quick changeover to sleet out of the picture in Southern PA. As a result, you will see our snowfall forecast now gets areas around and even north of i-80 in on the action.
All of us will start as snow, which will come in from southwest to northeast Wednesday Morning. By the afternoon, we will changeover from southwest to northeast to sleet, followed by freezing rain. We will get into precise timing with future radar, but first here is a graphic showing when we expected heavy snow to transition to sleet.
By 8:00 AM Wednesday morning, moderate to heavy snow will overspread much of the western half of the state. The morning commute will not be impacted, which is good and bad. The evening commute is going to be very hazardous. Because while these snow totals aren’t anything major, there is a big difference in 5 – 8″ falling in 15 hours, as opposed to six. Road crews will not be able to keep up with the snowfall rate in many areas. Here is future radar for 8:00 AM Wednesday:
The heaviest snowfall rates of 1 – 2″ an hour will come around lunchtime for many of us. Southwest PA will be likely have changed over to a wintry mix, while snow in Eastern PA pushes as far north as Scranton. Below is future radar for 11:00 Wednesday:
