Unfortunately the rain moving in from the west this afternoon and evening looks to deliver a near miss of the steadier and heavier rainfall that’s needed across the region. The heaviest rainfall looks to occur north of the region along I90 corridor with less as you head south. 
Both the GFS and Euro show the best chance for over .10” of rainfall occurring across Greene,Columbia and Delaware Counties. This will make very little impact on the driest parts of the region. Here is some perspective on just how dry parts of the region have been. 
The weather records in PHL date back to 1871, so this is an impressive dry spell for the fall season, and across areas south of our region even historically dry.
The short range HRRR is also not so friendly on rainfall amounts, the NAM is a bit of an outlier but worth mentioning as it suggests a southerly fetch of moisture that may spark some upslope rainfall across southern facing slopes of the higher terrain. Looking ahead the GFS and Euro remain quite dry through about Nov 8th so we will need to continue to exercise caution and abide by burn bans across the region.
