For the second morning in a row, wintry weather affected most of Eastern Pennsylvania (except for Philadelphia and Delaware Counties) on the 19th. The air mass aloft was warmer and the wintry precipitation was more of a mixture of sleet and freezing rain with some snow occurring over the higher terrain of the Poconos. In addition, thunderstorms with freezing rain occurred in the Philadelphia northwest suburbs. Snowfall averaged around two inches in the higher terrain of the Poconos. Ice accumulations averaged one to two tenths of an inch. Untreated roadways and sidewalks became slippery and hazardous, especially in Chester County.
Precipitation started briefly as sleet between 8 a.m. EST and 930 a.m. EST on the morning of the 19th. The precipitation then changed to freezing rain. In the Poconos. as the precipitation rate intensity increased, the freezing rain changed to snow over the higher terrain. The snow changed back to sleet just before ending around Noon EST.  Elsewhere, as warmer air reached the surface, the freezing rain changed over to plain rain around 11 a.m. EST. The rain also ended around Noon EST.
In Chester County, the icing conditions contributed to a fourteen vehicle pile-up, including a state police cruiser, in West Bradford Township on Shadyside Road. Several injuries occurred. An additional multi-vehicular accident in Coatesville on Pennsylvania State Route 82 closed the roadway for several hours.  In Lehigh County, the icing conditions forced the closure of Pennsylvania State Route 873 in both directions in Slatington. Several dozen flights in and out of Philadelphia International Airport were cancelled.
Representative snowfall included 2.0 inches in Tobyhanna (Monroe County) and Lake Harmony (Carbon County), 1.3 inches in Pocono Summit (Monroe County) and 0.6 inches in Lehighton (Carbon County). Ice accumulations included about two tenths of an inch in Allentown (Lehigh County) and Reading (Berks County), one tenth of an inch in Forks Township (Northampton County) and Pottstown (Montgomery County) and one-sixteenth of an inch in Bushkill Township (Northampton County).
The wintry mix of precipitation was caused by a southwest flow of milder and moister air accompanying a warm front that was located in the Ohio Valley on the morning of the 19th. The warm front reached Eastern Pennsylvania during the early afternoon of the 19th. By doing so, it brought above freezing temperatures into the area and also its proximity ended the necessary lift needed to generate precipitation.
