Discussion

Slightly milder air moved in overnight changing our wintry precipitation to plain rain and we'll continue to have some light rain or drizzle for part of the day. More moisture to our southwest will ride up an old frontal boundary zone on Tuesday in a southwest-to-northeast fashion and it looks like it'll be cold enough for all snow for this event across the Philly metro region. Snow is likely to begin during the early-to-mid morning hours on Tuesday and continue for much of the day with preliminary accumulation estimates on the order of 3-5 inches. Once this next system passes by, the second half of the week will be dry and very cold for this time of year.

A few notes about yesterday's snowfall in Philly...the Philly Airport officially recorded 8.6 inches which was only the 8th time that 8 inches or more has fallen in the month of December and 3 of those 8 events have occurred in the last 5 years. Also, yesterday's 8.6 inches was more than PHL recorded all of last winter.
