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.

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.

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.

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 ice and/or snow here early Tuesday morning with a coating of snow possible and a glaze of ice…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.
