Discussion
December begins on a chilly note and it looks like much of the first half of the month will feature colder-than-normal temperatures in the eastern half of the nation. In addition, the overall pattern looks to remain quite active with a couple of winter weather threats during the next several days. High pressure will build into New England today and then retreat to the northeast on Tuesday at the same time low pressure pushes toward the Mid-Atlantic coastline. Precipitation is likely to reach the area around or just before dawn and it could be cold enough for snow in most places. As the high retreats to the northeast, enough milder ocean air will push in to produce a changeover of the snow to rain and there can be icing for awhile during the transition. Accumulations are possible before the changeover on the order of a coating to as much as 2 or 3 inches in some of the far northern and western suburbs…lowest amounts in the Philly metro area and to its southeast. High pressure takes control of the weather for the mid-week and then a cold front arrives by Thursday night perhaps associated with a couple of snow showers. The coldest air so far pushes in on Thursday night and overnight lows could bottom out in the teens in some spots. After that, we’ll be watching the progression of another low pressure system to our south which could produce some snow around here by the end of the week.
