High pressure provided the Middle Atlantic region with a sunny, but cold day. After morning lows in the single digits around Baltimore and Annapolis, afternoon highs struggled to reach 20 degrees. The mercury will fall back to around 10 degrees by morning with clouds increasing from west to east, an indication of the next cold front that will sweep across the region and bring snow showers on Saturday. As the front progresses eastward during the day on Saturday, widespread snow showers will develop. The heaviest snow will fall across northern Maryland and southern Pennsylvania where an inch or two may accumulate by late afternoon To the south, a dusting to perhaps an inch may fall between Baltimore and Annapolis. With temperatures in the upper 20s during the afternoon, any snow that falls will cause roads and walkways to become snow-covered and slippery. Behind the front, a gusty west wind will make air temperatures in the mid teens feel more like zero by Sunday morning. Temperatures will actually begin to moderate on Sunday afternoon into Monday with overnight lows "only" around 20 on Monday morning and highs around freezing on Monday afternoon; however, much colder air will push across the bay region from Tuesday through Thursday of next week with perhaps the coldest air of the season. Lows overnight will once again fall into the single digits with daytime highs struggling to break out of the upper teens. There are some indications that a weather system may impact the coast by the middle of next week, but current computer forecast models keep the low too far away from Maryland to produce more than snow flurries or a snow shower. In summation, one of the coldest periods in the Middle Atlantic and New England states in many years will continue to hold firm through next week. On the bay, ice is expanding with many ponds, creeks, and rivers nearing a complete freeze-over.
