The Delaware Valley could get its first look at snow later this week as a front comes through and temperatures plummet, according to the National Weather Service.
The early part of the week is expected to be mild and mostly clear, with highs remaining in the mid- to upper-50s before things take a frigid turn late Thursday.
A report from NBC10's First Alert Weather Team forecasts a steep drop from the mid-50s on Thursday afternoon to lows falling below 20 degrees by Saturday morning.

It's doubtful there will be any snow accumulation in the event that the precipitation in the region does freeze, forecasters said.
The Farmer's Almanac predicted in August that the Philadelphia area should brace for a colder-than-normal winter that will bring heavy snow and persist into April.
