Watched the radar as the front started moving through between 4 am - 5 am, although the returns evaporated, so didn't get any precip from it. However saw the dp drop from ~71/72 down to the current 59, which is pretty dramatic. Temp was in the low-mid 70s and did a corresponding drop with the front crossing, and is now down to 68 at post time, with a deck of clouds overhead.
I saw that further west of here in central/western PA, the current temps are in the mid-50s.
ETA (1 hour later) - I got chance to pop out to the back and saw the plant foliage had been wet and was drying, although whatever came through this morning was not enough to tip the bucket. Still I'll take it.
