Low pressure will pull out of the southern states today and intensify as it heads to a position just off the Mid-Atlantic coastline by early tomorrow. There can be occasional light rain here today and steadier and heavier rain from tonight into early Saturday with the highest amounts in areas south and east of the District. There is an outside chance that it gets cold enough around here later tomorrow for the rain to briefly mix with or change to sleet and/or snow in some of the far western and northern suburbs as the storm intensifies off the Mid-Atlantic coastline and pushes to the northeast. Cold and dry weather should follow the storm around here to close out the weekend and then we'll have to watch another system on Monday that will push out of the Gulf of Mexico and towards the east coast.

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 pull out of the southern states on Friday and intensify as it heads to a position just off the Mid-Atlantic coastline by later Saturday. Significant rainfall is in the cards from this coastal storm in the DC metro region and in areas to the east coast. It may become cold enough for accumulating snow on Saturday in higher elevation, interior locations of the Northeast US including such areas as the Poconos (PA), Catskills (NY) and central/western New England - all good news for skiers. There is even an outside chance that it gets cold enough in the northern suburbs around here on Saturday for the rain to briefly mix with or change to sleet and/or snow on the back end of the storm.

The major storm system that began the week was the opening salvo in a colder and stormy weather pattern for the central and eastern US and another significant storm is in the offing for the early part of the weekend. 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.

Slow-moving low pressure will pull away from the region today, but it’ll stay quite windy and cold despite plenty of sunshine. High pressure will be in control of the weather for the next couple of days, but then a storm system from the southern states could make a move in our direction at the end of the week. In fact, there is the chance for some significant precipitation from this storm system in the Friday night/Saturday time period and it could be cold enough for a changeover to sleet and/or snow on the back end of the system. Longer term, the overall weather pattern that has evolved should continue to bring more frequent cold air outbreaks into the central and eastern US into at least the middle of the month of December.

A strong cold front passed through the region late yesterday as a powerful storm system pushed northward in the eastern Great Lakes. The upper-level low associated with this strong storm is a slow-mover and it’ll remain unsettled around here today and noticeably colder than yesterday. There is the chance for an additional rain shower or two and there can be flakes mixed in at times well to the north of the District. The overall weather pattern is changing to one that will result in more persistent cold in coming days across much of the central and eastern US.

A powerful storm system is churning northward today through the Appalachian Mountains and is having an important impact on a large part of the eastern third of the nation. The DC-to-Philly-to-NYC corridor has had steady and heavy rainfall this morning and the afternoon will present the possibility of some severe thunderstorm activity. Meanwhile, it is cold enough in the Midwest for snow to fall at mid-day and portions of the Ohio Valley will receive significant snowfall during the next 24 hours or so. An especially hard hit region may be northeastern Ohio where more than a foot of snow is possible in localized areas later tonight and Tuesday. This storm system is coming at the front end of an overall pattern change that will bring persistent colder conditions to the central and eastern US as we transition from the month of November to December.

A powerful storm system will begin the week with steady and heavy rainfall in the DC-to-Philly-to-NYC corridor as it pushes northward from the southeastern states. The precipitation pattern will take on more of a showery form this afternoon and there can be a couple of strong thunderstorms as it turns quite breezy and milder. The upper-level low associated with this strong surface storm will stall in the general vicinity on Tuesday and it’ll remain unsettled around here with the chance of additional showers and it turns colder as well. In fact, this storm system will be kind of a pattern changer as we transition into the month of December with colder conditions going forward for the foreseeable future. Another storm system may have an impact on the Mid-Atlantic region later this week or during the upcoming weekend.

The weather pattern will get pretty interesting in much of the US as we transition to the month of December and it is likely to include some significant temperature and height anomalies for this time of year. High pressure ridging in the upper part of the atmosphere will intensify dramatically next week across Canada at the same time colder-than-normal air sets up across the central and eastern US and there will be plenty of strong energy aloft. The transition to this colder and stormy weather pattern in the central and eastern US (and warm weather pattern across Canada) could begin with a major storm system in the Monday/Tuesday time period (i.e., last day of November and first day of December). A second storm could threaten the east coast at the end of next week and that system should have more in the way of cold air to work with in the eastern states.

A cold front passed through the region early yesterday and high pressure building across southeastern Canada is briefly in control of our weather. As a result, we’ll take a downturn in temperatures today with highs confined to 50 degrees or slightly lower which is below-normal for this time of year. Low pressure will influence conditions around here from late Wednesday night into Thursday with occasional showers likely through mid-day on Thanksgiving Day. High pressure builds back into the region at the end of the week and it should generate pretty decent weather in the Mid-Atlantic region for Friday and Saturday.
