Discussion
The rains associated with the remains of Hurricane Sally now extend from Georgia to central Virginia at the same time a strong cold front is pushing southeastward across the Great Lakes. Showers are possible here from later today into early Friday, but the heaviest of the "remnant" rains will stay just to our southeast. The passage of this cold front in the overnight hours will usher in a very cool Canadian air mass for this time of year and we'll experience our lowest temperatures so far in coming nights. Highs are likely to be confined to the 60's in much of the DC-to-Philly-to-NYC corridor from Friday through Monday and overnight lows can drop to the low-to-middle 40's in some suburban locations to the north and west of Philly.
