The overall weather pattern has been quite active in recent days in the eastern US with two different storm systems impacting the area in just the last three days. Numerous signs in the atmosphere point to a continuation of the stormy weather pattern in coming weeks across the eastern US and it is likely to become increasingly colder - raising the chances for accumulating snow. An on-going stratospheric warming event raises the prospects for high-latitude blocking in coming weeks which, in turn, increases the chance for increasingly colder outbreaks into the Mid-Atlantic/NE US. Teleconnection trends in such indices as the North Atlantic Oscillation (NAO) support the notion for a sustained period of high-latitude blocking which, in turn, would be more favorable for coastal storm development. In the near-term, one storm will likely push to the Carolina coastline on Friday and it may then stay to the south and east of the DC-to-Philly-to-NYC corridor as it heads out-to-sea - but it still needs to be closely monitored. Another winter storm is likely to threaten the southern and eastern US during the early or middle parts of next week as the active pattern continues.

Low pressure which impacted the region with a mixture of precipitation on Sunday will push away from the New England coastline today and the next weather maker for us will be a cold front to our northwest. This cold front will pass through the area on Tuesday afternoon and bring with it a chance of rain and/or snow showers. High pressure will take control of the weather around here for Wednesday and Thursday and then we’ll have to watch the movement of a storm system expected to be over the Carolinas as we close out the work week on Friday. This system could stay to our south and head out-to-sea, but it is something to monitor next few days.

An active weather pattern will continue into the new year with one low pressure system bringing precipitation here later Friday and Friday night and then a second system will impact us on Sunday. The first system will result in accumulating snow for parts of the Upper Midwest and Ohio Valley and mainly a rain event for the Mid-Atlantic region. However, it can be cold enough at the onset of the event later tomorrow for a brief period of sleet in some of the northern and western suburbs. After an unseasonably mild day on Saturday, it'll turn colder by Sunday and a second low pressure system will intensify near the Mid-Atlantic coastline bringing us more precipitation to close out the weekend.

An active weather pattern will continue into the new year for the eastern half of the nation with one low pressure system bringing a potpourri of precipitation on Friday and then a second system late in the weekend that should intensify near the Mid-Atlantic coastline. The first system will result in accumulating snow for parts of the Upper Midwest and Ohio Valley on New Year’s Day (Friday) and mainly a rain event for the Mid-Atlantic region. However, it can be cold enough at the onset on Friday in the Mid-Atlantic region for a brief period of sleet and/or freezing; especially, in areas north of the PA/MD border. Late in the weekend, a second low pressure system will likely intensify near the Mid-Atlantic coastline and it would have an influx of colder air – a potential setup that needs to be monitored in coming days.

A cold frontal system slipped through the region in the overnight hours and today will turn out to be quite windy and cold despite mainly sunny skies. High pressure will shift off the coast on Wednesday and another cold front will slide through the region later Thursday. Moisture will arrive here by early Friday as strong low pressure pulls out of the southern states and heads towards the Ohio Valley. This system will result in mainly a rain event here on New Year’s Day, but it may be cold enough at the onset for some sleet and/or freezing rain with a cold air mass in only slow retreat. It’ll turn milder by Friday night and Saturday before another cold front pushes across the region late Saturday and then we’ll have to watch for a potential low pressure system to develop near the east coast on Sunday.

A powerful cold front will barrel towards the eastern seaboard from later today into early Friday and it’ll bring some wild weather to the Mid-Atlantic/Northeast US. Ahead of the front, heavy rains, possible thunderstorms, and potentially damaging winds will develop and raise the prospects for localized flooding and power outages. It’ll become much milder as well today with temperatures soaring to the 60 degree mark by late in the day in the NYC metro region. On the back side of the front, temperatures will plunge on Friday from their mild early morning highs in the 50's to the 30’s by the end of the day. Any standing water on untreated surfaces that is left behind by the heavy rain event could freeze-up in a hurry on Friday as temperatures take that plunge. The cold air mass will stick around into the weekend with temperatures on Saturday struggling to reach the freezing mark.

Ahead of the front, heavy rains, possible thunderstorms and potentially damaging winds will develop and raise the prospects for localized flooding and power outages. It’ll become much milder as well on Thursday with temperatures soaring to the 60 degree mark in the DC, Philly and NYC metro regions. On the back side of the front, temperatures will plunge on Friday from their early morning highs to at or below freezing by later in the afternoon. Any standing water on untreated surfaces that is left behind by the heavy rain event could freeze-up in a hurry on Friday as temperatures take a plunge.

A powerful cold front will come barreling towards the east coast late tomorrow night/early Friday and it’ll bring some wild weather with it to the Mid-Atlantic region. Ahead of the front, there will be heavy rain, possible thunderstorms, and potentially damaging wind gusts which, unfortunately, raises the prospects of power outages. It’ll become much milder as well on Thursday with temperatures likely flirting with the 60 degree mark for late day highs. The combination of heavy rainfall and mild conditions will cause a rapid melting of snow and this is likely to lead to localized flooding in areas of poor drainage. On the back side of the front, temperatures will drop rapidly on Friday from the mild levels early to the 30's by late in the day. The cold air mass will stick around as we begin the upcoming weekend with temperatures on Saturday struggling to pass the freezing mark.

A powerful cold front will come barreling towards the eastern seaboard later this week and it’ll bring some wild weather with it to the Mid-Atlantic/Northeast US from later Christmas Eve (Thursday) into early Christmas Day (Friday). Ahead of the front, there will be heavy rain, possible strong thunderstorms, and potentially damaging winds which, unfortunately, raises the prospects of power outages. It’ll become much milder as well on Thursday with temperatures likely flirting with the 60 degree mark for late day highs in places like DC, Philly and NYC. The combination of heavy rainfall and mild conditions will cause a rapid melting of snow and this is likely to lead to localized flooding in areas of poor drainage.
On the back side of the front, temperatures will drop rapidly following the heavy rain event to below the freezing mark in many spots resulting in a quick freeze-up of standing water on untreated surfaces. Snow accumulations of several inches are likely in the colder air mass across portions of the Ohio Valley and interior Mid-Atlantic/Northeast US. There can even be a brief changeover to sleet and/or snow in the I-95 corridor early Friday morning as the colder air rushes into the region, but a “flash freeze” is the greater concern.
