Periods of Rain

Rain showers will be the story for today. Currently as of 7am, there are pockets of rain over Southeastern PA, well west of the city from Lancaster to Harrisburg.  The rain is moving from a SSW to NNE direction and will continue to move in this direction affecting the western suburbs of Philadelphia over the next few hours.  Points east in the city and New Jersey/Delaware are probably gonna stay dry for the next few hours.  But the overall area of coverage of rain will increase during the afternoon/evening hours.

The rain is due to a low-pressure system well to our west over the Tennessee/Ohio valley that will slowly move north through today and tomorrow and track well to the west of our region.  Being on the eastern side and in turn with a strong area of high pressure offshore, we'll have a decent south to southeasterly flow off the ocean that will help to ignite numerous rain showers, and perhaps even a thunderstorm here and there.  This is not an event that will produce a high amount of rain, but expect on and off showers over the next 48 hours.  The system will begin to lift out late Wednesday/early Thursday and after this system moves out, the rest of Thurs and Friday look spectacular with lots of sunshine and late summer-like temperatures, with highs getting close to 80 degrees.

Temperatures will rise only slightly throughout the day ranging from the upper 60's to lower 70's.  Winds will be out of the south and southeast at around 5 mph.
