Low pressure passes by to our north this morning and it’ll bring us a period of snow that can quickly accumulate from a coating to an inch or so. Given the cold ground conditions, even a light precipitation event can result in slippery conditions on the roadways through the morning hours. High pressure returns later today bringing some sunshine to the area and Christmas Day should feature some sunshine as well with moderately cold conditions.

The lowest temperatures so far this season greeted the new week in the Mid-Atlantic region with single digits in many suburban areas along I-95 and as low as ten below in the Poconos of northeastern PA. In fact, this morning’s temperature readings were the lowest in many spots of the Mid-Atlantic since about Christmas time two years ago when a brief, but severe cold snap hit the area. An Arctic high will weaken and shift offshore tonight and then low pressure to our north will bring a period of snow and ice on Tuesday morning. While this won’t be a heavy precipitation event on Tuesday morning, a burst of snow and ice can certainly cause problems on roadways which are quite cold given the recent chill.
Looking ahead, there are plenty of signs for a cold pattern to emerge in January with a deepening trough of low pressure likely to form over the eastern states. This upcoming cold pattern is likely to have some staying power as well given the development of strong high-latitude blocking across Canada. Numerous teleconnection indices support the notion of a cold pattern in January for much of the central and eastern US. In addition, given the potential positioning of the trough in the central and eastern US, the southern branch of the jet stream may very well become quite active which enhances the chance for snowstorms in an overall cold pattern.

A very cold start to the new week with Arctic high pressure still in control across the Mid-Atlantic region. This high departs early tonight and a weak low pressure system to our northwest can produce a band of snow here early Tuesday morning which may be mixed with sleet and/or freezing rain…a coating to an inch or so is possible, watch for slippery spots as road conditions are quite cold. Some sunshine will return for Tuesday afternoon and also Wednesday, Christmas Day, and it stays moderately cold for this time of year.

A “clipper” low pressure system dropping southeast from the Great Lakes will combine with an intensifying oceanic low to produce snow in the region from later this morning into early Saturday and it can be mixed with rain at times during the day. Accumulations of snow on the order of a coating to as much as 2 or 3 inches are on the table by early tomorrow morning. As the oceanic low intensifies on Saturday and pulls off to the northeast of here, the coldest air mass of the season so far will pour into the region this weekend. Temperatures on Sunday will be confined to the low-to-mid 20’s for afternoon highs – the coldest day so far this season - and the overnight lows by early Monday morning could be in the upper single digits across some suburban locations.
One final note, for those planning to attend the college football playoff game at Penn State on Saturday (noon start)…bring blankets…high temperatures in the middle 20’s, windy with much lower wind chill values, and maybe a snow shower or two.
