May 15th, 2012 Forecast

A gloomy and soggy start to the workweek will continue into mid-week and a low pressure forms off the coast, drawing in precipitation from a separate system.  We'll dry out nicely, however, and are in the sights for another fantastic weekend coming up.   Rain will be heaviest Monday night and into Tuesday as we might see some ponding on poorly drained roadways as well as small streams and creeks.

For most of Monday, rain has remained light and to the north and west of Philadelphia.  As the low pressure forms off the coast, the precipitation shield will be drawn east, further to the coast.  Tonight, skies will remain overcast with the showers becoming increasingly more steady.  Temperatures will be fairly mild, in the upper 50's to mid-60's with winds from the south.  Tomorrow the deluge continues tomorrow, with rain being heavy at times and the chance of thunderstorms in the afternoon.  Temperatures tomorrow will be in the mid-70's for the most part and winds still from the south.

Rain totals for Monday into Tuesday range from one to three inches, however if stronger thunderstorms train over a certain area, rain totals could be locally higher.  Flash flood guidance for the area is still fairly high, with most areas needing over two inches in an hour to see serious flash flooding.  On the contrary, the area is still about five to six inches down on our rain total for the year, so any amount of rain is well needed.

Wednesday the precipitation chances stick around for Wednesday with a chance of showers early then a chance for thunderstorms in the afternoon.  Wednesday will also be the warmest day of the 7-day.  Temperatures relax Thursday as skies clear and the sun comes out.  The sun sticks around for the rest of the week and into the weekend.  Temperatures stay in the mid to upper 70's with lows in the mid to upper 50's.  The start of next workweek looks similar, dry and warm with abundant sunshine.
