COLD AIR WILL BRING THE THREAT OF BLACK ICE AND FROZEN PIPES TONIGHT... The coldest air of the season has blasted into the area. Low temperatures tonight are forecast to drop into the single digits across the extreme northern portions of the area, with lows in the teens to lower 20s across the rest of the region. Due to recent precipitation, there will be the potential for patchy black ice tonight and Wednesday morning in locations where roadways remain wet. As the name implies, black ice is difficult to see on roadways and can result in slick spots. Reduce speed and remain alert! The prolonged period of sub-freezing temperatures will also bring the threat of frozen pipes tonight. Cover exposed pipes and allow a slow drip from exposed faucets.
