A high impact winter storm is getting underway in the Mid-Atlantic region and it will push into the Northeast US later today and continue into early Thursday. Sleet will become a big player in the DC-to-Philly corridor with freezing rain in the mix as well and this will limit total snowfall accumulation amounts. This storm will be primarily a snow event across upstate PA, interior upstate NJ, NY and New England and rain will dominate from southern NJ-to- the southern half of the Delmarva Peninsula-to-southeastern Virginia. Travel conditions will become quite difficult for the Wednesday PM and Thursday AM commutes from this major winter storm.

A high impact storm is coming to the Mid-Atlantic/Northeast US at mid-week with significant snow for some, ice and rain for others and winds will become a big factor as well. The big cities along the DC-to-Philly-to-NYC corridor will have accumulating snow as well as a period of mixed precipitation and the heaviest snowfall amounts will be on the northwest side of the I-95 corridor. Rain will dominate in areas from coastal southern New Jersey to the southern half of the Delmarva Peninsula to southeastern Virginia.

This will be a stormy week in the Mid-Atlantic region with two storms to deal with during the next few days. The first storm on Monday will begin with rain in all areas of the DC-to-Philly-to-NYC corridor, but as colder air filters from a strengthening high pressure system to the north, a changeover to accumulating snow is likely to take place in suburban areas to the north and west of the big cities. A second and powerful storm will arrive at mid-week and it is likely to result in significant snow, ice and rain for the Mid-Atlantic region with a mixture possible in parts of the metro areas, heavy snowfall to the north and west, and primarily rain near and along coastal sections of southern New Jersey and the Delmarva.

The interesting and active weather pattern of recent weeks will continue into at least the middle of the month with two storms on the table for this week in the Mid-Atlantic/Northeast. The first storm for the Mid-Atlantic/Northeast US will come on Monday and an even bigger threat comes at mid-week with the greatest potential impact. In fact, the mid-week storm could turn out to be a major snowstorm for a large part of the Mid-Atlantic/Northeast US. In the short term, the weather remains mild during the next couple of days in much of the eastern half of the nation, but a colder air mass is going to filter into the northeastern quadrant of the nation on Sunday night and Monday following the passage of a cold front - setting the stage for a very wintry week.

The interesting and active weather pattern of recent weeks will continue into at least the middle of the month with two storm threats on the table for next week in the central and eastern US. The first storm threat for the Mid-Atlantic/Northeast US will come during the early part of next week and an even bigger threat comes at mid-week with the greatest potential impact. In fact, the mid-week storm could turn out to be a major snowstorm for a large part of the Mid-Atlantic/Northeast US. In the short term, the weather turns milder in much of the eastern half of the nation, but a colder air mass is going to filter into the northeastern quadrant during the early part of next week following the late weekend (uneventful) passage of a cold front.
Teleconnection indices such as the Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) are supporting the idea of “high-latitude blocking” to get well-established by the middle of next week which, in turn, supports the idea for strong high pressure to build across southeastern Canada – always a key factor to the prospects of getting accumulating snowfall in the I-95 corridor. In this time period, two separate waves of energy will cross the southern states and then move northeastward towards the Mid-Atlantic coastline. With a cold air source building to the north across the southeastern part of Canada by the middle of next week, this type of setup could result in significant accumulating snow for at least parts of the Mid-Atlantic/Northeast US.

A cold front is approaching the Mid-Atlantic region and it is accompanied by a strong wave of energy in the upper part of the atmosphere and a powerful jet streak. As a result, snow showers have broken out across much of the Northeast US and Mid-Atlantic region and they are dropping southeastward at this hour towards the DC-to-Philly-NYC corridor. There is the chance for a heavier burst of snow in some spots which can cause small accumulations and quickly developing slick spots on the roadways. High pressure resumes control of the weather for the latter part of the work week.

A cold front will arrive in the Mid-Atlantic region on Wednesday and it will be accompanied by a strong wave of energy in the upper part of the atmosphere and a powerful jet streak. As a result, snow showers can break out on Wednesday; primarily, in areas near and to the north of the PA/MD border region, and there is even the chance for small accumulations in some spots. High pressure resumes control of the weather for the latter part of the work week.

The major storm system that began the week in the Northeast US was the opening salvo in a colder and stormy weather pattern for much of the eastern half of the nation and another significant storm is in the offing for the early part of the weekend. Low pressure will pull out of the southern states on Friday and intensify as pushes to a position just off the Mid-Atlantic coastline by early Saturday. Rain is in the cards from this storm in the cities along the DC-to-Philly-to-NYC corridor and in areas to the coast; however, it will become cold enough for accumulating snow in higher elevation, interior locations of the Northeast US with the heaviest snowfall amounts likely coming to interior New England. There is an outside chance that it gets cold enough on Saturday in the I-95 corridor and coastal sections for the rain to briefly mix with or change to sleet and/or snow during the back end of the storm.

Low pressure will likely pull out of the southern states at the end of the week and intensify as it arrives in the northeastern quadrant of the nation. Significant rain is in the cards from this potential storm in areas along the coast and back to the I-95 corridor; however, it may become cold enough for accumulating snow during the second half of the storm in higher elevation, interior locations of the Mid-Atlantic and Northeast US and inland sections of New England may end up with a major snowfall. In fact, there is an outside chance that it gets cold enough this weekend in portions of the immediate I-95 corridor for the rain to mix with or change to sleet and/or snow during the back end of the storm.
