Arctic high pressure will build across the region through tonight, maintaining mainly dry, but cold conditions.
Clouds will increase on Saturday ahead of a weak low pressure system which is forecast to cross the area Saturday night and Sunday. Snow is expected to develop late Saturday afternoon, and continue into Sunday. The snow may come in multiple waves with breaks in between. Amounts look to be fairly light with accumulations through the weekend of 1 to 3 inches.

Low pressure is forecast to track northeastward toward the Mid Atlantic region on Wednesday. This system may be far enough west to bring the threat of snow. Highs on Wednesday will recover to the mid 20s.
