Two low pressure systems will be passing through the area between today and the beginning of next week, bringing some cold air and a couple of chances for precipitation over the weekend. The first system is moving eastward from its current position over the Great Lakes and is likely to arrive on Friday, bringing a chance for rain on Friday afternoon and evening, and temperatures below freezing overnight.

Two low pressure systems will be passing through the area between today and the beginning of next week, bringing some cold air and a couple of chances for precipitation over the weekend. The first system is moving eastward from its current position over the Great Lakes and is likely to arrive on Friday, bringing a chance for rain on Friday afternoon and evening, and temperatures below freezing overnight.

The second system is originating over the Gulf of Mexico and will be passing by us off the coast on Sunday night. This will pull down some colder air from the north again, and may cause rain and some light snow. This set up will mean daily high temperatures in the 40s or low 50s (°F) until the middle of next week and overnight temperatures dipping a few degrees below freezing.

While cold, Saturday and Sunday before the second system arrives should have clear skies.
