An energetic weather pattern is evolving and we’ll have to deal with multiple storm systems over the next several days and cold air outbreaks. The next system of significance will bring rain here late tonight into early tomorrow as a warm front pushes northward through the region and there can be residual showers later in the day on Friday and also tomorrow night. On Saturday, low pressure will form nearby and a cold front will advance towards the region resulting in more rain around here as we begin the first weekend of January. That cold front will usher in strong winds and colder air for Saturday night and Sunday and, as the low pressure intensifies just to our northeast, there is the chance for rain changing to snow by early Sunday. A “clipper” low pressure system will follow closely and it could spread some snow shower activity into the Mid-Atlantic late Sunday and early Monday and then another storm will have to be watched for later Tuesday as it pulls out of the south-central US and towards the Ohio Valley. That system will usher in another cold air mass for the Mid-Atlantic region by the middle of next week.

The new year will be ushered in with brisk and cold conditions with a touch of snow possible and then high pressure will build into the region for Wednesday night and Thursday. A storm system will then impact us with rain at the end of the work week and first part of the weekend. First, a warm front will spread some rain into the area beginning late Thursday night/early Friday and then a cold front will keep us wet on Saturday. The winds will pick up noticeably by Sunday as the next cold shot arrives and we’ll have to watch a clipper system dropping southeastward across the Great Lakes early next week as it could result in some snow shower activity around here.

A cold frontal system will work its way through the region today and the afternoon will feature a pick up in the winds as a chilly air mass arrives. The winds will continue to be brisk tonight and on Wednesday along with moderately chilly conditions as we usher in the new year. High pressure will then give way to another storm system for Friday and Saturday with periods of rain possible on both days.

The new work week will start off on the wet side as low pressure forms over a frontal boundary zone in the region and generates periods of rain, some of it can be briefly on the heavy side and there can be a rumble of thunder. A cold front will move through the area on Tuesday and pave the way for a cold New Year’s Eve and a cold New Year's Day. High pressure stays in control later on Thursday, but more rain is possible at the end of the week.

An Arctic front crossed the region late yesterday and ushered in a much colder-than-normal air mass for this time of year.

The cold will become less harsh by tomorrow, but it’ll stay colder-than-normal going right into the weekend.

An Arctic frontal system will arrive in the I-95 corridor later today/early tonight and it will be accompanied by strong wind gusts, snow showers, and heavier snow squalls. Any snow squall can reduce visibilities in a hurry, put down a quick coating of snow and create dangerous driving conditions. It’ll stay windy tonight and on Thursday and it’ll turn sharply colder with some of the lowest wind chill values and temperatures so far this season in the Mid-Atlantic/NE US.
