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 by the early part of the weekend likely to produce rain showers in the area and then a strong storm can generate showers and thunderstorms across the Tennessee Valley by Tuesday of next week.

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.
