Crisp, Chilled Day With Rain & Snow Showers

Simply put, today is not going to be a very nice day.  A weak disturbance is pushing east through the Mid Atlantic and will spread rain and snow showers through the region.  Those showers will be modest in nature and not produce a ton of precipitation.

Looking at recent guidance, precipitation looks to be more likely along and north of the city, opposite of thinking 24 hours ago which had the lion's share of precipitation to the south.  Expect showers to move through starting mid morning and continuing through the afternoon hours before tapering off close to dinner.  Snow accumulation, if any occurs, would be on grassy services and probably more likely over elevated areas north or northwest of Philadelphia and probably won't be much.

Temperatures will not be very warm -- the city's morning temperatures in the lower and middle 40's are likely going to be the day's highs, with only some upward mobility in temperatures possible to the south during the morning hours where temperatures are a bit colder out of the gate thanks to mostly clear skies lingering longer overnight.  In general, highs today range from 40-45 city and north, around 45 to the south, with temperatures perhaps easing back a few degrees with precipitation moving through later.

With an east and northeast breeze averaging out to 10 mph, it will feel a bit colder out but winds will be less of a factor today than the past two days.  In terms of "reality", it would be more akin to a January day than a March day.  Given it was in the 70's last year on St. Patrick's Day, this year's 40's will be a cruel reminder of what March is often about.
