As we close out January and head into February we should be in the lower 40s by day and the middle 20s by night; there seems to be a trend where it's either cold and sunny or mild and wet. Today was no exception as after a frigid low of 10 at Philly International(it was below zero in the suburbs!) we reached 28 for a high just before 4pm. High pressure was on top of us so there wasn't much of a wind either.
There is a clipper system to the west that will provide clouds overnight so I only expect lows to be in the upper teens to around 20 in Center City(middle teens in the burbs) with a light southerly wind. Friday will be partly sunny, but highs will be in the lower 40s so FINALLY it's a seasonable Winter day(although it will feel like Spring to us!).
For the weekend that clipper stalls to our south, but then lifts back north as a warm front. This will not only provide rain, but temperatures will be in the upper 40s on Saturday; we hold there overnight and then reach the middle 50s by lunchtime Sunday with rain ending early and the rest of the day will just be mostly cloudy(if you are having a Super Bowl party you should encounter no weather problems getting to your destination). Come Monday the cold front pushes through, but not before having some leftover moisture in the morning. This means as temperatures fall through the lower 40s in the morning we will have a cold rain and even some wet snow to the north.
Tuesday temperatures will be close to 40 in advance of another system, but it should be rain Tuesday night as temperatures rise(except north and west where there may be some cold air damning and some light snow at the start) into Wednesday with highs in the upper 40s.
