Shower chances increase by late today. We could see a couple of thunderstorms later today and continue tomorrow morning. This should be a pretty healthy regionwide rain event with at least 0.50" to 1.50" of rain for most of us in the north and west Philly burbs. After that, the weather looks great for the weekend. Temperatures will start well below normal tomorrow with highs struggling to escape the 50's in ridge locations, but we will warm back up slightly above normal with highs in the mid 70's for Mother's Day.

Over the last 4 days we have received 2.19" of rain here in East Nantmeal. We are now only 2.40" below normal or 85% of normal rainfall as those drought conditions continue to lessen.

The rain associated with a cold front could drop between an 1.0" to 1.5" of rain across the area. We turn much chillier on Friday with some higher ridge locations remaining in the upper 50's for high temperatures. We warm nicely by the weekend with temperatures within a few degrees of normal at around 70 degrees.
