There will be three different systems to deal with in the Mid-Atlantic region during the next week or so with a relatively minor storm tonight and then a major storm this weekend. Yet another storm could impact the Mid-Atlantic region with rain and/or snow by the middle of next week. Tonight’s system is likely to result in a coating to an inch or two in the DC-to-Philly-to-NYC corridor with the higher amounts to the north and west of Route I-95 and lesser amounts to the south and east. A major storm will bring lots of precipitation to the Mid-Atlantic region this weekend with everything on the table from heavy rain to accumulating snow and accumulating ice. An Arctic blast will flood the region on the heels of the storm late in the day on Sunday and this could result in a quick freeze-up and potential hazardous driving conditions. Single digit lows are likely by early Monday morning and the coldest day of the year so far will likely see temperatures struggling to get out of the teens in the I-95 corridor.

A cold and stormy weather pattern is getting locked in for the eastern US and there may be three different systems to deal with over the next week or so. Low pressure will head in our direction today and it’ll produce some accumulating snow around here tonight with a coating to two inches likely by morning. There is a chance that the snow changes to light freezing rain towards daybreak just before the precipitation ends. A much more significant and complex storm is going to impact the I-95 corridor this weekend and everything is on the table for this event for the NYC metro region including heavy rain and significant accumulations of snow and ice. Precipitation is likely to begin in the afternoon on Saturday as snow or perhaps a wintry mix and there can be accumulations before a likely to a wintry mix or rain at night. The rain could change to sleet, freezing rain and then snow on Sunday as colder air rushes in behind the system. In fact, a plunge in temperatures late Sunday following the departure of the storm can cause a quick freeze-up on many surfaces with potential hazardous conditions developing. The coldest air mass of the season so far will likely result in single digit lows by early Monday morning and highs may very well be confined to the teens to start the new work week.

A cold and stormy weather pattern is getting locked in for the eastern US and there may be three different systems to deal with over the next week or so. On Thursday, low pressure will head in this direction from the Ohio Valley and likely produce some snow around here on Thursday night. A much more significant storm is going to impact the I-95 corridor this weekend and everything is on the table for this event including rain, ice and/or snow. It is still too early to determine the magnitude of each precipitation type for the DC-to-Philly-to-NYC corridor, but accumulations of ice and snow are on the table. In addition, as the weekend storm pulls to the northeast later Sunday, Arctic air will flood the Mid-Atlantic region and any precipitation that lingers can change to ice and then snow before ending. Also, as temperatures plunge late Sunday, a “flash freeze” is possible in some areas with a quick ice up on roads, etc. The coldest air mass of the season so far will likely result in single digit lows in parts of the region by early Monday morning and highs may be confined to the teens to start the new work week.

A cold front will pass through the region tonight and usher in slightly colder and drier air for Thursday which will feature increasing clouds ahead of the next low pressure system. This next low pressure is likely to bring some accumulating snow to the area on Thursday night with a preliminary estimate of 1-3 inches for the NYC metro region - higher amounts to the north and west and the lower amounts to the south and east. The snow could end as a bit of sleet or light freezing rain early Friday morning and there can be a few slippery spots as a result. A significant storm is coming this weekend with everything still on the table from rain-to-ice-to-snow. Much colder air will pour in on the back side of the storm late Sunday and this could result in a "flash freeze" whereby roads, etc. ice up in a hurry. The coldest air mass of the year could result in single digit lows by Monday morning and highs no better than the teens.

An active weather pattern is setting up for the next several days with two systems to monitor and an Arctic blast by the early part of next week. Low pressure will push out of the Ohio Valley on Thursday and likely produce accumulating snow in much of the Mid-Atlantic on Thursday night. That snow could end as a period of light rain or freezing rain early Friday which could make for an interesting AM commute to end the work week. The weekend will feature a strong cold frontal system sliding towards the east coast and a strong storm will form along the boundary zone. That system may bring us some rain, but snow and/or ice are possible at the front end and also on the back end…many, many details still have to ironed out. What is quite certain is that the coldest air mass of the season will arrive late Sunday on the heels of the weekend storm and Monday promises to be very cold.

A cold front will pass through the region tomorrow night and usher in colder air for Thursday which will feature increasing clouds ahead of the next low pressure system. This next low pressure is likely to bring some accumulating snow to the area on Thursday night which could end early Friday as light rain or freezing rain - possibly impacting the AM Friday commute. A strong cold front will arrive in the eastern US this weekend and a significant storm will develop along its boundary zone. The result is likely to be lots of rain, ice and/or snow for much of the Northeast US, but it is too early to tell how much of each will fall in the DC-to-Philly-to-NYC corridor. Snow and ice will be more likely across interior, higher elevation locations and rain will be more likely along coastal sections. On the back side of the storm, bitter cold Arctic air will flood the Mid-Atlantic region late Sunday into Monday and this could cause "flash freeze" conditions with a possible quick ice-up. Single digits are possible by early Monday morning - the coldest air mass so far.

Low pressure will pull away from the Mid-Atlantic coastline today and high pressure will build into the region for the first part of the new work week. Temperatures over the next few days will be moderately cold for this time of year and there should be plenty of sunshine each day. Another cold front will approach on Wednesday night and usher in reinforcing chilly air for the late week. Another cold front will arrive this weekend and strong low pressure may form along the frontal boundary zone and impact our weather.

A large area of snow currently extends from the central Plains to the Ohio Valley and it is closing in on parts of the Mid-Atlantic region. There will be two stages to this weekend snow event with overrunning and jet-streak induced light-to-moderate snow later today and early tonight. By late tonight and for the day on Sunday, low pressure induced snow aided by upper-level energy will produce heavier snow; primarily, in the region near and south of the PA/MD border. In fact, the heaviest snow accumulations in this event are likely to come in the region from Virginia-to-Delmarva Peninsula-to-southern New Jersey. This is looking like a prolonged event with snow possibly lasting until later tomorrow night in some parts of the Mid-Atlantic.

Accumulating snow is falling today in the Colorado Rockies and this storm system will spread snow this weekend from the central Plains to the Mid-Atlantic. Low pressure will be located over Oklahoma early tomorrow and generally head in an eastward direction towards the Tennessee Valley, and ultimately, will transfer its energy to the coastal region of North Carolina. Snow will break out early Saturday in the central Mississippi Valley and then advance eastward to the Ohio Valley by mid-day and to the Mid-Atlantic region during the late PM hours. On Sunday, as low pressure takes over at the North Carolina coastline, snow will wind down from northwest-to-southeast and it’ll last the longest in areas south of the PA/MD border. Heaviest amounts of snow during this upcoming weekend event in the Mid-Atlantic region are likely to take place in parts of Virginia, Maryland, Delmarva Peninsula and southern New Jersey.

Accumulating snow is likely this weekend in much of the Mid-Atlantic region, but the New York City metro region will be on the northern fringes with little accumulation expected around here. Low pressure will pull out of the southern US on Saturday and head towards the Tennessee Valley before ultimately winding up near the Outer Banks of North Carolina by late Sunday. Snow will break out on Saturday in the central Mississippi Valley and then push eastward to the Ohio Valley and then to the Mid-Atlantic region during the PM hours. The best chance of snow here comes tomorrow night as precipitation stays mainly south of the PA/MD border on Sunday with low pressure nearing the North Carolina Outer Banks. Preliminary snowfall estimates for the NYC metro region range from a coating to an inch or two during this weekend event.
