This is a very tough system to forecast, as there are three parts to it. It may still have a few more tricks up its sleeve, but here is how things stand now. Recent model trends in the past 12 – 18 hours have brought the incoming snow farther south and west in Pennsylvania. As a result, much more of the state is expected to get in on heavier accumulations. Widespread cancellations are likely Monday across all of the eastern half of the state. Let’s time it out below.
LATEST STORM TIMING
Snow is expected to begin in parts of central and northern PA by early Monday morning. Below is NAM future radar for 1:00 AM Monday.
Temperatures Monday will be in the upper 20s in northern PA, and the low 30s in southern PA. It may have a tough time sticking to the roads in parts of the Lower Susquehanna Valley, unless heavier bands occur. Elsewhere in the state though, we expect snow-covered roads. Snow will continue all of Monday morning and into the afternoon in most of Pennsylvania. Below is future radar for 1:00 PM Monday.
Finally by late Monday evening, snow will come to an end in most of eastern PA. Here is future radar for 1:00 AM Tuesday.
