Discussion              

Rain associated with a northeastward moving storm system will spread into the Philly metro region later this morning and it’ll continue into the day on Saturday.  Some of the rain will become heavy at times, watch for localized flooding, and winds will increase in strength from an east-to-southeast direction. In fact, at the height of the storm, flooding may become an issue along coastal sections of New Jersey given the fact that a stiff east-to-southeast flow of air will continue for a several hour period.  

By the time we get to the second half of the weekend, a multitude of upper-level lows will begin to consolidate into one as the northernmost system will become the dominant player and acts to “absorb” the other lows. The end result will be one deep upper-level low by the early part of next week centered over the eastern Great Lakes. At the surface (and very similar to the first system on Friday and Saturday), an initial (primary) low will push towards the Great Lakes and a secondary storm will form near the Mid-Atlantic coastline by late Sunday night/early Monday.  As with the first event, this second one will result in soaking rains for the Philly metro region and winds will become quite a noticeable factor as well. An unusually chilly air mass for early May will follow the second storm for the first half of next week and instability showers may take place from time-to-time.
