Low pressure pulls away from the coast today leaving us with plenty of clouds, windy and chilly conditions. High pressure takes control for tonight and tonight and then a weak “clipper” heads this way by Wednesday. That system can produce a couple of rain and/or snow showers around here from late tomorrow night into early Wednesday morning before another high pressure system takes over for the late week.

A light northeast flow of air will keep us mainly cloudy today and on the chilly side and there can will be occasional light rain or drizzle with patchy fog as well. Another storm system will impact the area with more rain during the second half of the weekend as one low pressure system (primary) heads into the Ohio Valley and a secondary will forms near the Mid-Atlantic coastline. While there will be little cold air around initially, strong high pressure will build into southeastern Canada and act as a cold air source. This is likely to result in a changeover from rain-to-snow across much of the interior, higher elevation locations of the northern Mid-Atlantic region and potentially, there can be a changeover in around here on Sunday night.

It’ll remain wet and mild in the NYC metro region for today and tonight with patchy fog around as well. It remains on the damp side on Friday and there will be a battle in terms of air temperatures around here with warmer air likely limited in its northward advance keeping the metro area in the 40’s to close out the work week. Another storm system is then going to impact the Mid-Atlantic on Sunday and Sunday night with one surface low pressure system (primary) heading into the Ohio Valley and a secondary likely to form near the Mid-Atlantic coastline. While there will be little cold air around initially, strong high pressure will build into southeastern Canada and act as a cold air source. This is likely to result in a changeover from rain-to-snow across much of the interior, higher elevation locations in the Mid-Atlantic and potentially, all the way down to the NYC metro region on Sunday night.

The next couple of days will be wet, foggy and mild in the Mid-Atlantic region and there will be a surge of temperatures on Friday in much of the I-95 corridor. Another storm system is then going to impact the Mid-Atlantic late in the weekend with one surface low pressure system (primary) heading into the Ohio Valley and a secondary likely to form near the Mid-Atlantic coastline. While there will be little cold air around initially, strong high pressure will build into southeastern Canada and act as a cold air source. This is likely to result in a changeover from rain-to-snow across much of the interior, higher elevation Mid-Atlantic region on Sunday night and there is a chance for a changeover to snow all the way down into the N/W suburbs of the big cities.
Elsewhere, the overall pattern for the next several days will bring copious amounts of rainfall to the Lower Mississippi and Tennessee Valleys - areas that have been quite dry in recent weeks - and to the US west coast from California-to-Washington which will be inundated by multiple storms during the next couple of weeks.

The next few days will be milder in the Mid-Atlantic region and quite wet as well as moisture steadily flows to the northeast from the Gulf of Mexico. The warmest day of the week will be on Friday when temperatures surge to the upper 50’s in the NYC metro region. Another storm system is then likely to impact the Mid-Atlantic region later in the upcoming weekend with one surface low pressure system (primary) heading into the Ohio Valley and a secondary likely to form near the Mid-Atlantic coastline. While there will be little cold air around initially, strong high pressure will build into southeastern Canada and act as a cold air source…possibly resulting in a changeover from rain-to-snow on Sunday night.

Strong high pressure system will push off the eastern seaboard today opening the door for moisture to push northeastward from the Gulf of Mexico and into the northern Ohio Valley. From there, the moisture will slide eastward later tonight bringing us the chance for late night rain and it could freeze on some surfaces across the northern and western suburbs. On Wednesday - and also during the days on Thursday and Friday - it should be warm enough for just plain rain to fall throughout the metro region. Indeed, the warmest day of the week is likely to be on Friday at which time afternoon temperatures might peak near the 55 degree mark. The weekend begins on a mild note, but it turns colder by Sunday and low pressure is likely to bring us some rain to close out the weekend.

The 7-day period from 14 January to 20 January was very cold across most of the nation with the mean temperature anomaly of -11°F in the Lower 48. The next 7-days will be quite a different story as a milder weather pattern develops for much of the country. This warm-up, however, will not come without wintry threats in the Mid-Atlantic region and Northeast US. The change in the overall pattern will bring copious amounts of rainfall for the Lower Mississippi Valley region in the near-term and plenty of moisture-filled storm systems for the US west coast during the next couple of weeks.
In the near term, there is likely to be some freezing rain from later Tuesday night into early Wednesday across much of Pennsylvania and northern New Jersey and maybe all the way into the nearby N/W suburbs of Philly and NYC and the far N/W suburbs of DC. It does turn wet and milder in the Mid-Atlantic region during the second half of the week with the warmest day likely to be on Friday when temperatures will surge. Another storm system is then likely to impact the Mid-Atlantic/Northeast US late in the upcoming weekend with one surface low pressure system (primary) heading into the Ohio Valley and a secondary likely to form near the Mid-Atlantic coastline. While there will be little cold air around initially, strong high pressure will build into southeastern Canada and act as a cold air source…possibly resulting in a changeover from rain-to-snow across interior sections of the Mid-Atlantic/Northeast US. Looking ahead, there are signs that an overall colder weather pattern may re-develop in the central and eastern states as we progress through the early part of February and towards the middle of next month.

Arctic chill continues to have the Mid-Atlantic region in its grips this morning with many spots in the teens and there are a few places in the single digits across interior sections of New Jersey. After highs in the 30’s later today, temperatures should reach 40+ degrees on Tuesday afternoon. There will be a chance of some rain late tomorrow night and it can freeze on some surfaces across the far northern and western suburbs…something to watch for going into Wednesday morning. The weather does turn noticeably milder during the second half of the week and it’ll be quite unsettled as well with multiple chances for rain.

Another round of accumulating snow gets underway early today in the NYC metro as low pressure intensifies off the Carolina coastline. The snow will come down at varying rates around here during the day with likely final accumulation amounts of 2-4 inches by the early part of tonight and isolated higher amounts are possible. An Arctic air mass will follow this system with some bitter cold conditions for the weekend, but the chill will slowly fade away during the early part of next week. In fact, rain may return to the forecast by the middle and latter parts of next week as a “January thaw” develops and takes us to the end of the month.

Another round of accumulating snow is headed to the Mid-Atlantic region on Friday and it should get underway early in the day in the DC-to-Philly-to-NYC corridor. This is a dynamic storm system that will have strong upper-level support and complicating factors will include small-scale heavier snow bands that are likely to develop and an inverted (aka “norlun”) trough that will extend northwestward back to the Mid-Atlantic region from the low pressure center out over the western Atlantic. On the heels of the snow, another Arctic air mass will plunge into the eastern US for the weekend and lower teens or even upper single digit overnight lows will be possible in many suburban locations. Looking ahead, the Arctic chill will dissipate early next week and we’ll turn warmer-than-normal for the middle and latter parts with rain likely back into the forecast.
