Discussion

Warmer air is pushing into the Mid-Atlantic region and this warm surge will reach its zenith on Thursday. Unfortunately, the warmer weather will be accompanied by periods of rain and some of the rain can fall heavily at times later tomorrow into tomorrow night. The record high for Christmas Eve in Philly is 64 degrees - actually set just one year ago – and it is in jeopardy this Thursday. In fact, Philadelphia's all-time December record high of 73°F - set on two days in 1998 during the last strong El Nino event – also will be in jeopardy this Thursday. A cool front will slide through by Friday, Christmas Day, bringing slightly cooler air into the area, but it’ll stay above normal for this time of year. It will remain unsettled late in the week and weekend with showers possible late Friday and again each weekend day.
