Following the cold front that passed through the area early this morning, temperatures will be about 15 degrees colder today, with a high in the mid 50s.

It’s time to protect your gardens and exposed pipes from freezing! Pressure will rebuild into the weekend, so temperatures will warm back into the 60s and overnight lows will warm into the 30s by Saturday.
