7:00 AM | **Occasional rain or drizzle right through tonight...cold blast arrives this weekend with below-freezing conditions late Sunday night and late Monday night**

6-Day forecast for the Philadelphia, Pennsylvania metro region

Today

Mainly cloudy, chilly in the morning, but turning milder in the afternoon, occasional rain or drizzle, cannot rule out a thunderstorm, highs near 60 degrees late in the day; NE winds at 5-10 mph

Tonight

Occasional rain, breezy, turning colder late, lows in the mid 40’s

Friday

Partly-to-mostly sunny, mild, breezy, upper 50’s for afternoon highs

Friday Night             

Partly cloudy, cold, near 40 degrees for late night lows

Saturday

Partly sunny, breezy, cooler, chance for a few mid-day and PM showers, not out of the question that a bit of sleet or snow pellets mix in with any rain late in the day, low-to-mid 50’s

Sunday

Partly sunny, windy, cold, mid-to-upper 40’s

Monday

Mainly sunny, breezy, quite cold for late March, near 40 degrees

Tuesday

Partly sunny, still quite cold, mid-to-upper 40’s

Discussion              

Occasional rain or drizzle will continue through tonight as a secondary low pressure system forms near the northern Mid-Atlantic coastline and a thunderstorm cannot be ruled out.  After a relatively mild day on Friday, the weekend will turn increasingly cold and NW winds will intensify following the passage of two cold frontal systems.  With the arrival of the initial cold front on Saturday, there can be a few rain showers and perhaps even a bit of sleet or graupel (i.e., snow pellets) mixed in at times late in the day. Temperatures on Sunday will be confined to the 40’s for afternoon highs and below-freezing conditions are very likely late Sunday night and again late Monday night. In fact, it stays quite a bit colder-than-normal for the latter part of March right into the middle part of next week.
