May 19th, 2012 Forecast

If you could ask for the perfect spring weekend, this one might be on the top five or ten.  A turbulent week has slowly transitioned into a great build up to an even better weekend.  It has come with a cost though as those thunderstorms Tuesday into Wednesday traveled very slowly over parts of Montgomery, Chester and Delaware counties causing road closures and prompting water rescues.  Another group of thunderboomers created lots of lightning, and may have been the cause of the chemical fire in Bucks County and the apartment fire in Philadelphia.

It is going to be a great night to keep the windows open in the house and let the cool air drift right in.  Temperatures in the upper 40's in the outlying areas to the lower 50's closer to the metro.  Part of the reasoning is because there won't be a lot of clouds around to keep in the heat from the daytime sunshine and there will be very little wind.  Some places in the Poconos might dip into the lower 40's.  Winds will be from the east at around 5 mph.  A nearly perfect start to the weekend continues into Saturday.  The sun will be plentiful and temperatures will hover close to 80-degrees.  Winds will move to the northeast as a double high pressure will set up to our northeast and southwest.

Sunday will be almost the same as Saturday, with the exception that this nice weather will have to end.  There will be more clouds in the sky and towards the evening and overnight, some showers could form.  Monday through Wednesday will feature a continuing chance of rain and thunderstorms, with the best chance sometime Tuesday.  Temperatures will drop slightly, to the mid to upper 70's.  Thursday, will clear out ahead of a jem of a holiday weekend.

Friday, some models indicate a quick passing shower in the morning, but clearing out.  A look ahead into Memorial Day Weekend look nearly the same as this upcoming weekend, maybe a little warmer.  Skies look to be partly to mostly sunny.  There is some disagreement as to the high temperature Sunday into Memorial Day Monday.  Mid to upper 80's seems like a good baseline, however models indicate the possibility of reaching the 90-degree mark.
