Discussion
A warm front will approach the region later today and it should generate some shower activity around here during the overnight hours. After its passage on Thursday, temperatures should jump into the 60’s, but a strong cold front will bring an end to the warm up by the weekend. This cold front will likely bring more rain to the area tomorrow night and on Friday and then colder air pushes in by the early part of the weekend. At the same time the cold air arrives, low pressure will try to push northward from the southern states along the stalled out frontal boundary zone. If that system can make it this far north - and it appears increasingly likely - it may be just cold enough for some snow in the region by late Saturday.
