A very active weather pattern will continue this week with two powerhouse storm systems to deal with across much of the nation. The initial storm system will produce lots of snowfall from today into Tuesday in a zone from the central Plains to the Midwest. This same system will produce heavy rain on Tuesday afternoon and Tuesday night in the Mid-Atlantic region and Northeast US with significant flooding on the table. In addition, strong and potentially damaging winds will accompany this first storm system raising the chance of power outages from later tomorrow into Wednesday across the northeastern states.
By the end of the week, another powerful storm system will be taking shape and this one will have more in the way of Arctic air to work with and a blizzard is likely across much of the Midwest with additional heavy rainfall and strong winds destined for the eastern seaboard. The passage of the weekend storm will usher in much colder air for the Mid-Atlantic and Northeast US and signs continue to point to some intense cold possibly moving into the central and eastern US by early next week. In addition, attention will turn to the possibility of yet another storm system to deal with in the eastern states during the early or middle part of next week.

An active weather pattern will result in another storm system impacting the Tennessee Valley with rain and wind. The best chance for moderate to heavy rainfall comes from later this evening into tomorrow morning and winds will be impactful as well with gusts past 40 mph on the table. Rainfall amounts can reach 2-3 inches in some spots raising concerns for localized flash flooding to become a real concern. Another storm system threatens the Tennessee Valley at week’s end and early this weekend with the potential for a similar pattern of high winds and heavy rainfall.

An active weather pattern will produce a couple of systems to monitor in the Tennessee Valley region during the next several days. One system pushes northeastward from the southern states in the short-term likely to produce rain showers in the area from late tonight into mid-day on Saturday. A strong storm can generate showers and thunderstorms across the Tennessee Valley by Monday night and Tuesday of next week and some of this rain can be heavy at times.

The active weather pattern of recent days will continue during the next several across the eastern half of the nation. A winter storm will impact the Mid-Atlantic region this weekend with accumulating snows across interior sections and a mixture of precipitation in the big cities along the I-95 corridor. Another storm system will impact a large part of the eastern half of the nation in the Tuesday/Wednesday time frame and this one looks like a powerhouse. It is likely to feature very heavy rainfall, interior accumulating snows, and potentially damaging winds with power outages on the table in many states. If that isn’t enough, there may be another strong storm system to deal with in the eastern states by the early part of next weekend.

The active weather pattern of recent days will continue during the next couple of weeks across the eastern half of the nation…and that may be quite an understatement. One storm system will impact the Mid-Atlantic region this weekend with wintry precipitation favoring accumulations across the interior and likely a mixture in the big cities along I-95. Another storm system will impact a large part of the eastern half of the nation in the Tuesday/Wednesday time frame of next week and this one looks like a powerhouse. It is likely to feature very heavy rainfall, interior accumulating snows, and potentially damaging winds with power outages on the table. If that isn’t enough, there may be a couple of more systems to deal with in the eastern half of the nation by the time we get through the mid-point of January.

An active weather pattern will produce two systems to monitor in the Tennessee Valley region during the next several days. One system pushes northeastward from the south-central states today and it can produce some rain/snow showers in the area. High pressure will then take control of the weather into the end of the week, but another system will head this way from the southern US by early Saturday. This weekend system is likely to produce rain in the region on Saturday, but drier weather is likely by early next week.

An active weather pattern will produce two systems to monitor in the Tennessee Valley region during the next several days. One system pushes northeastward from the south-central states at mid-week and it can produce some rain showers in the area on Wednesday. High pressure will take control into the end of the week, but then another system will head this way from the southern US. This system is likely to produce a threat of rain in the region come late Friday night into Saturday.

A northern hemisphere stratospheric warming event that began during the latter part of November will rise to new levels within the next ten days or so and this could have important ramifications on temperatures across the central and eastern US from later January into February. Temperatures at the stratospheric level of 10 millibars will climb dramatically over the next ten days or so from about -70 degrees (Celsius) to about -25 degrees (Celsius) as warming aloft intensifies over the polar region of the northern hemisphere. The “polar vortex” that typically resides near or over the North Pole during this time of year will become displaced and “stretched” in coming days and this could unleash some high latitude cold air masses into the middle latitudes by the time we get into later January and February. In the near term, the weather pattern will be quite active across the eastern states with multiple systems to monitor during the next couple of weeks and temperatures will return to more seasonal levels.

A large-scale upper-level low is spawning a couple of low pressure systems that will impact the region from tonight into Friday. Initially, it’ll be mild enough for rain showers, but as slightly colder moves in there can be some snow shower activity by tomorrow night and into the day on Friday.
