THIS WEEK’S WEATHER

Not so nice Sunday?

Updated Thu 9/08 8:32 PM —Well, after looking over some other models, the ECMWF and the GFS may be too fast with the rain moving in Sunday afternoon. The Canadian and German ICON models keep the rain in central Pennsylvania for much of Sunday afternoon and the latest model blend (NBM) leans towards that forecast.  Will have to wait for clarification.

Update Thu 09/08 @ 7:42 PM — A significant change in the forecast for Sunday. While I had thought much of the weekend would be very nice, it appears that clouds move in earlier on Sunday morning with rain possible by early to mid late afternoon, especially areas just of west of the city.

The rain for Sunday afternoon is forecast, especially west of Philadelphia, by the GFS, NAM and ECMWF models.

Today’s 18z GFS shows light rain just moving in about 1 PM on Sunday. The ECMWF has the rain a little further eastward. (Click on image for a larger view.)

There may be a break in the action following this initial wave of showers, with rain returning by evening.
