An Arctic cold front will approach the region later today and likely bring with it some snow shower activity and perhaps even a brief period of steadier snow that could result in accumulations of a coating to an inch or so. The time period of concern for this quick burst of snow is roughly 2-6 pm…watch for slick spots, rain can also mix in at times. The weekend will be quite cold with Arctic high pressure in control limiting our temperatures to the lower 30’s for afternoon highs on both days.
By the latter part of the weekend, low pressure will begin to intensify over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of accumulating snow on its north side. This system will slide from west-to-east producing a significant snowfall along the way across the Midwest later Sunday and then likely reach the DC region with accumulating snow by late Sunday night. Precipitation from this storm system can last all the way into Monday night with several inches of snowfall on the table. One complicating factor with respect to the potential snow accumulation amounts will be the likelihood for some sleet and/or freezing rain to mix into the picture; especially, in the southern half of the metro region. This low pressure will then slide off the east coast on Tuesday and more Arctic air will follow encompassing a wide part of the nation.

A colder and active weather pattern is indeed unfolding for the central and eastern US and it is likely to bring two threats of snow to the Mid-Atlantic region during the next several days. First, an upper-level wave will rotate around the base of a large-scale trough of low pressure later tomorrow and it can produce snow showers in the area and maybe even a period of steadier snow; primarily, in the region from DC/northern Delmarva-to-southeastern PA/southern NJ…small accumulations are on the table. A surge of Arctic air will follow the system later tomorrow night setting us up for a cold weekend in the Mid-Atlantic region. A more important threat of snow comes for late Sunday night and Monday as low pressure moves eastward from the Midwest with significant accumulations on the table in portions of the Mid-Atlantic region including the DC-to-Philly corridor.

It turns colder today and then even colder this weekend following the passage of a cold front on Friday night that will usher in Arctic air for Saturday and Sunday. The cold front can produce snow showers around here later tomorrow Friday - maybe even a period of steadier snow - and an Arctic high pressure system will take control by the weekend.
By the latter part of the weekend, low pressure will begin to organize over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of accumulating snow on its north side. This system will slide east by Sunday night and Monday producing a significant snowfall in the Midwest and there is a good chance for accumulating snow here on Monday with several inches on the table. This system will then slide off the east coast by Tuesday of next week and more Arctic air will encompass a wide part of the nation.

The passage of a cold front will usher in cooler air for today and winds can gust to 50 mph on the backside of departing low pressure. It turns progressively colder later this week and weekend as the pattern change to much colder-than-normal kicks into full gear. There will also be the chance for snow shower activity on Friday as we transition to colder conditions with the passage of a cold front…even an outside chance for small accumulations.
By the latter part of the weekend, low pressure will begin to organize over the middle of the nation and it’ll have quite a bit of cold air to work with resulting in plenty of snow on its north side. This system will slide east by Sunday night and Monday likely producing a decent snowfall in the Midwest and there is a chance for some snow to make its way into at least portions of the Mid-Atlantic with the southern half of the region likely having the highest probabilities (e.g., DC, Baltimore). This system will then slide off the east coast around Tuesday of next week and Arctic air will encompass a wide part of the nation.

A much colder-than-normal weather pattern is about to commence for the central and eastern US and it looks like it’ll be one with some staying power. In fact, this upcoming cold stretch for much of the nation may feature some extreme cold and very cold conditions may penetrate all the way into the southern states from Texas-to-Florida. In addition, there are likely to be multiple snow threats in this developing weather pattern that can impact much of the central and eastern US to go along with the expected much colder-than-normal temperatures. Next week looks particularly interesting in a period that may feature some extremely cold air and multiple threats of snow including one in the Sunday/Monday/Tuesday time frame for the Midwest and at least portions of the Mid-Atlantic. Numerous teleconnection indices support the notion of a much colder-than-normal weather pattern, and an unfolding stratospheric warming event enhances the idea that the much colder-than-normal temperature pattern can be sustained well into the month of January.

Low pressure will bring more rain to the region from later today into tonight and there can be a strong thunderstorm mixed into the picture. Moderately cold air will follow for Thursday and Friday on the heels of a mid-week cold frontal passage. It’ll turn even colder this weekend as our long anticipated pattern change to much colder-than-normal conditions becomes better established. This pattern change to colder weather for the central and eastern states will be quite active as well and there may be some snow in the DC-to-Philly-to-NYC corridor by early next week. Bitter cold Arctic air could be in the cards across much of the nation by later next week and a second storm threat is possible as well.

A much colder-than-normal weather pattern will set up for the central and eastern US during early January and it looks like it’ll be one with some staying power. In fact, this upcoming cold stretch for much of the nation may feature some extreme cold and very cold conditions may penetrate all the way into the Deep South from Texas-to-Florida. In addition, there are likely to be multiple snow threats in this developing weather pattern that can impact much of the central and eastern US to go along with the expected much colder-than-normal temperatures. Next week looks particularly interesting in a period that may feature multiple snow and ice threats and potentially some extremely cold air. Numerous teleconnection indices support the notion of a much colder-than-normal weather pattern, and an unfolding stratospheric warming event enhances the idea that the much colder-than-normal temperature pattern can be sustained well into the month of January.

The beginning of the week will remain on the mild side with some sunshine today and then the next low pressure system will bring us more rain from later tomorrow into early Wednesday, New Year’s Day. Moderately cold air will push into the Mid-Atlantic region at mid-week and it turns even colder during the upcoming weekend. In fact, a much colder-than-normal weather pattern will set up for much of the central and eastern US and it looks like it’ll be one with some staying power. This upcoming cold stretch may feature some extreme cold and very cold conditions may penetrate all the way into the Deep South from Texas-to-Florida. In addition, there are likely to be multiple snow threats in this developing weather pattern that can impact much of the central and eastern US to go along with the expected much colder-than-normal temperatures. Next week looks particularly interesting that may feature multiple snow threats and some extreme cold may get mixed into the picture.
Get ready…January might just be a wild month of weather.

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 across a few of the far 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.
