July 21st, 2012 Forecast

After our fourth heat wave and a series of storms, some could consider Friday abnormally or almost alarmingly cooler.  Temperatures in the mid-60's to mid-70's with the first batch of showers slowly moving out and another batch of showers primed to move through in a few hours.  This stationary front isn't making things easy elsewhere either.  A flood watch is in effect for the central part of the state and many roadways near Pittsburgh are under water.  There are also flood watches for central Maryland, and coastal flood advisories for New Jersey and Delaware   So far today there is a variety of rainfall amounts ranging from anywhere from an inch to three inches in parts of New Jersey, while Philly has only picked up just over a quarter of an inch so far today.

Tonight, mostly cloudy skies will prevail with scattered, or more like waves, of shower activity throughout the night into tomorrow morning.  These slow movers could cause rapid flash flooding, so if you have a weather radio or another means to get severe weather updates, make sure it's in working order.  Still feeling humid tonight, with lows in the mid-60's to near 70-degrees as you head south and east.  Tomorrow, those lingering showers taper off in the morning hours and leave us with mostly cloudy skies.  Some peaks of sun in the late-afternoon.  Highs in the lower 80's around the metro, keeping in the 70's as you head north and west.  Also not too warm along the shore, either.  Winds both tonight and Saturday shift to come from the northeast.

Sunday looks like the better day of the weekend.  More sunshine and slightly warmer temperatures, with lower humidity.  Late Sunday is our next chance of precipitation, but the daylight hours should be dry.  We bump the temperatures Monday with a chance of showers and thunderstorms.  Tuesday is much of the same, except eclipsing the 90-degree mark.  We'll actually flirt with 90-degrees for a few days, so if temperatures do trend warmer, we could be in the midst of possibly a fifth heatwave.  The showers and thunderstorms move off for Wednesday, and temperatures moderate to near-normal levels.  We'll keep that trend through Thursday and into Friday, however another chance of storms are possible late Friday.
