The theme over the course of the day today is off and on showers, drizzle, and rain based on location. It's not going to be the nicest of days locally. It'll be a damp and not very splendid Saturday around the region as precipitation lingers and lurks through the course of the day.
The steadier rains will fall south of the city, generally this morning and midday, before pulling out to sea. Low pressure, which moves up the coast, will wrap moisture through the region as showers and drizzle fall locally through the course of the day. Rainfall amounts will vary around the region -- with anywhere from a couple of tenths of an inch to perhaps a half inch common north of Dover and Cape May, and more than a half inch south of there through tonight.
Temperatures, as usual with these southern systems, will vary a bit from north to south. Temperatures could flirt with 50 along the coast later today, with 40 or above south of Doylestown to Reading later on today. Philadelphia should get into the mid 40's before day's end. The Lehigh Valley might hit 40 this afternoon, but 30's will hold tight through the Poconos today as temperatures will be slow to climb up in the mountains.
Showers and drizzle should wind down later this afternoon from southwest to northeast, with precipitation lingering into the Poconos this evening. It could, perhaps, transition back to freezing drizzle or freezing rain later tonight in the Poconos if temperatures slip back below freezing before precipitation tapers off. It's something we'll keep an eye on through the day. Around here though, expect showers, drizzle, or intermittent light rain.
