The winter landscape of leafless trees, low sunrises and cold mornings is upon us, even though winter doesn't officially begin until Dec. 21. Today, the mercury will climb to a high of 33, with a low in the 20s overnight. Cheer up, Baltimore will be veritable Miami compared to Western Maryland, where temperatures could sink to the teens and even single digits. There is a 12 percent chance of precipitation, with winds rising to a blustery 20 mph. These conditions will continue at least through Friday. BRRRRRRRRR!
