A low pressure system will slide to our north later today and pull a strong cold front through the region which will usher in a reinforcing cold and dry air mass to end the work week. The passage of the front this evening will likely be accompanied by gusty winds, snow showers, and perhaps even a heavier snow squall or two across much of upstate Pennsylvania and New York State. The cold front will then will set up shop on Friday in the southern Mid-Atlantic region and low pressure will slide along the frontal boundary zone resulting in accumulating snow all along the DC-to-Philly-to-NYC corridor from later tomorrow evening into early Saturday. While there will be limited moisture available to this system and it’ll be a fast-mover, a strong and strengthening upper-level jet streak will enhance upward motion in the DC-to-Philly-to-NYC corridor and the result will be a few inches of snow by early Saturday morning. Contrary to the storm earlier this week, this upcoming system will encounter an established cold, dry air mass on its front side meaning snow will likely be the dominate precipitation type all the way down to the DC metro region.

A low pressure system and its associated cold front will cross the Mid-Atlantic region later tonight possibly generating an evening rain shower and then high pressure returns on Friday. Low pressure will ride along that frontal boundary zone by the early part of the weekend and there can be some accumulating snow around here from later Friday evening into early Saturday morning and then the rest of the weekend to follow will be rather cold and breezy. Preliminary snowfall estimates are 2-4 inches by early Saturday morning in the DC metro region…isolated higher amounts are possible.

After yesterday’s combination of rain and snow, high pressure returns to the region for today and it’ll be cold and breezy with highs confined to the low-to-mid 40’s. A clipper low pressure system and its associated cold front will cross the Mid-Atlantic region tomorrow night possibly generating a rain shower here and then high pressure and slightly colder air returns for the end of the work week. Low pressure will ride along that frontal boundary by the early part of the weekend and there can be some accumulating snow here from Friday night into Saturday morning and the rest of the weekend to follow will be quite cold and breezy.

A dynamic storm system is impacting the Mid-Atlantic region this morning with an infusion of cold air from the northwest causing a transition to sleet and/or snow in many areas from the overnight rainfall. It is possible that a burst of heavier snow and/or sleet takes place during the next couple of hours which can quickly have an impact on roadway conditions. The afternoon should turn out dry, but the winds will remain a factor gusting up to 40 mph or so. Accumulation amounts of a trace in areas just to the south and east of DC metro to as much as 2-3 inches in some of the far northern and western suburbs are on the table before the precipitation winds down by late morning. High pressure takes over at mid-week with moderately cold conditions expected.

A very dynamic storm system is headed to the Mid-Atlantic region and Northeast US and it is going to produce sleet and significant accumulating snow in many sections with an impact on at least part of the Tuesday morning commute…and “thundersnow” is even on the table. There is no real cold air established for the onset of the approaching storm so precipitation arrives this evening in the form of rain all along the immediate DC-to-Philly-to-NYC corridor. However, as the surface low intensifies off the Mid-Atlantic coastline early Tuesday, colder air will get quickly wrapped into the system from the north and west, winds will intensify, and there will be a changeover from rain-to-sleet-to-snow. Significant accumulations of snow are likely on Tuesday morning across Pennsylvania, central/northern New Jersey, and in the New York City metro region. There can even be some accumulations early tomorrow across northern Maryland and all the way into the northern and western suburbs of Washington, D.C.

A potent storm system will push out of the Tennessee Valley later today and up the Appalachians before transferring to an intensifying coastal storm by later tonight. Rain will overspread the region this evening and then possibly mix with sleet and snow by morning across the northern and western suburbs and continue as a mix on Tuesday morning….a coating to an inch or two is possible. High pressure returns for the mid-week time frame with breezy and cold conditions.

The last two days were quite mild across the Mid-Atlantic region with highs reaching the upper 50’s in many areas and even the lower 60’s in a few spots. A cold front pushed through late Saturday, but there will not be any truly cold air mass following it for the beginning of the new work week. Later Monday, an intensifying storm system will push towards the Mid-Atlantic region and with no cold air established, rain will fall initially in the DC-to-Philly-to-NYC corridor. As the storm pushes to the Mid-Atlantic coastline and intensifies, colder air will wrap into the system from the north and west later Monday night into early Tuesday. As a result, a changeover to snow is likely across Pennsylvania, central/northern NJ, and in the New York City metro region with accumulations on Tuesday morning and there will be an impact on the AM commute in many spots. A changeover to snow is less likely across the DC metro region and southern New Jersey, but even there some sleet and snow is likely to fall early Tuesday.

The next two days will be very mild across the Mid-Atlantic region with highs reaching the upper 50’s in many areas and 60+ degrees in a few spots. A cold front pushes through later Saturday with some rain shower activity, but there will not be any truly cold air mass following it for the beginning of the new week. Later Monday, an intensifying storm system will push towards the Mid-Atlantic region and with no cold air established, rain is likely to fall in the DC-to-Philly-to-NYC corridor. As the storm pushes to the Mid-Atlantic coastline, colder air will wrap into the system from the north and west on Monday night and a changeover to snow is possible all the way down to the I-95 corridor. Accumulations of snow are on the table by early Tuesday; especially, in areas to the north of the PA/MD border.

Milder weather will continue in the Mid-Atlantic region for the next couple of days with temperatures likely reaching 60 degrees each afternoon. There will be clouds and limited sun today and mostly cloudy skies on Saturday with the chance of showers as a cold front pushes through the region. The overall weather pattern will become colder next week and the front-end of this transition is going to be accompanied by a strong storm system from later Monday into Tuesday. Given the lack of cold air at the onset, odds favor rain initially in the local area; however, colder air can wrap into the system from the north and west so there is a chance for an changeover to snow in some sections and accumulations cannot be ruled out.

Milder weather is on the way to the Mid-Atlantic region for the next few days with temperatures likely to peak on Saturday afternoon in the low-to-mid 60’s despite featuring plenty of clouds and the good chance of showers. The overall weather pattern will change next week to colder-than-normal conditions for the central and eastern states and the front-end of this transition is likely to be accompanied by a strong storm system from later Monday into Tuesday. Given the lack of cold air at the onset, odds favor rain in the local area, but colder air can wrap into the system from the north and west so there is a chance for an eventual changeover to snow in some areas. It turns quite cold and windy by the middle of next week on the backside of this storm…all part of the upcoming significant pattern change.
