Winter Storm Watches and Winter Weather Advisories have been issued for much of Pennsylvania ahead of our first widespread significant winter storm of the season. Starting on Sunday from the Appalachians and on east, a prolonged period of moderate freezing rain will lead to dangerous travel in many areas. This will be followed on Sunday night into Monday by a snowstorm in eastern PA, and up into New England.
Scattered power outages are possible in the Appalachians (including the Poconos) on Sunday, in addition to very hazardous travel conditions. We advise avoiding travel if at all possible. On Monday, snow in Eastern PA will likely cause school delays/closings, and a very difficult morning commute especially north of Allentown and Pottsville.
STORM TIMING
Freezing rain will overspread all of central PA by dawn Sunday, possibly starting as a quick sleet/snow mix in the northern mountains. Here is future radar for 7:00 AM Sunday.
Freezing rain will move north and east into eastern PA by late morning. Nearly all of central and eastern Pennsylvania will be seeing freezing rain and treacherous travel conditions by early Sunday afternoon. Future radar for 1:00 PM Sunday is below.
The coastal storm will takeover Sunday evening, and throw wintry precipitation back into much of eastern and central PA by early morning Monday. This is when the Poconos and the Lehigh Valley will begin to see moderate snow. Here is future radar for 1:00 AM Monday.
Snow will continue in much of eastern PA Monday morning, with heavy snow bands of 1″ an hour likely in the Poconos. The Monday morning commute in these areas will consist of slippery, snow packed roads. Below is future radar for 7:00 AM Monday.
Snow will continue through the first half of Monday afternoon, before winding down and moving east. Future radar for 1:00 PM Monday is below.
