Update, 9 AM: The earlier radar returns over Central Pennsylvania have fizzled, leaving us in a relatively dry lull for the next few hours. More precipitation is still across Western Pennsylvania. Depending on whether that activity survives the trek over the mountains, we could see some showers this afternoon. Skies are trying to brighten somewhat around town, with temperatures in the 40's south of the city and 50's in Southern Delaware.
This morning's current temperature, radar, and warning overlay shows the first round of the storm across Northern and Northeastern Pennsylvania, pulling east. Last night's "storm" dropped a coating of snow across the northern burbs and brought snowflakes mixing in with rain to the city proper, while areas to the north saw measurable snowfall. Totals range from those coating amounts in the suburbs to a couple of inches in the Lehigh Valley to 3-6" across the Poconos this morning. Along with a wide array of snowfall totals comes a wide array of temperatures as warm air lurks to our southwest this morning. Temperatures range from the 20's in the Poconos to the 50's down in Washington this morning, with low and mid 30's around the Philadelphia region. The milder air to our southwest will work into Delaware and perhaps South Jersey for a time near midday before some rain moves back in this afternoon.
Advisories and warnings remain out for parts of the region -- with a winter weather advisory out for Bucks and Montco until 10 AM due to the potential for some slick spots on some of the side roads around town and the potential for more precipitation to move in towards mid-morning. That precipitation is just showing up on the radar overlay up above and is quickly moving east. It should move in here in the form of rain after 9 AM, moving through by midday.
Round two is back in the Midwest and will move on in tonight, with snow for parts of the region and additional accumulations for areas generally south of the Pennsylvania Turnpike and Route 70 in New Jersey. We'll highlight the "how much for round two" later on today (won't be a ton of snow but it should be enough to shovel overnight).
