High pressure stays in control of the weather for another day before the weather turns quite unsettled in the Mid-Atlantic region. Low pressure will impact the region with rainfall later tonight and Saturday…the rain can freeze on some surfaces in the wee hours of the morning; especially, across some of the northern and western suburbs. Another and even stronger low pressure system arrives on Sunday along with breezy and milder conditions and this one will bring more rain to the area, some of it can be heavy at times, and there can be a thunderstorm mixed into the picture. Yet another system is likely to bring more rain to the region by Tuesday, New Year’s Eve.

High pressure stays in control of the weather through tomorrow before the weather turns quite unsettled in the Mid-Atlantic region. Low pressure will impact the region on Friday night with some rainfall around here primarily in the after midnight hours. Another and even stronger low pressure system arrives on Sunday along with milder conditions and this will bring more rain here to close out the weekend…some of which can be heavy at times.
One final note, watch out for icy spots (i.e., black ice) early today due to the combination of temperatures near the freezing mark and low-level moist conditions.

December 1776 was a desperate time for George Washington and the American Revolution. Morale was low, hope for winning the war was diminishing, and the Continental Army led by George Washington was thinning in numbers after many battles lost to the British. December began with lots of rain and muddy travel conditions for the men which did not help with their spirits. After retreating through New Jersey, they set up camp on the Pennsylvania side of the Delaware River where the army was met with very cold weather that led to plenty of ice on the water. All in all, things were not looking good for Washington's army. However, George Washington devised a plan that would change the course of the war and the history of our nation.

Low pressure passes by to our north this morning and it’ll bring us a bit of freezing rain that can be mixed with sleet and snow for a brief time at the onset. Given the cold ground conditions, even a light precipitation event can result in slippery conditions on the roadways through the mid-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.

Low pressure passes by to our north this morning and it’ll bring us a brief period of snow that is likely to be mixed with sleet and/or freezing rain. Given the cold ground conditions, even a light precipitation event can result in slippery conditions on the roadways right through the morning hours. A coating of snow is possible and there can be a light glaze of ice to top it off. High pressure returns later today bringing some sunshine to the area and Christmas Day should feature some sunshine as well with moderately cold conditions.

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.
