Intense cold this weekend with powerful and potentially damaging winds…
The combination of a clipper low pressure system and its associated cold front will produce snow showers in the area later today and tonight and there can be brief heavier snow bursts. Small accumulations are possible on the order of a coating to an inch and there can be slippery spots on the roadways. After the passage of the cold front, an Arctic air mass will plunge into the Mid-Atlantic region from eastern Canada leading to a bitter cold weekend. This Arctic air mass is the real deal, had its origins on the Siberian side of the North Pole, and will not have the usual modifying effects of crossing over the relatively warm Great Lakes. In addition to the bitter cold, biting winds will become a major factor on both weekend days with gusts of up to 55 mph producing dangerously low wind chill levels of well below zero and raising the possibility of power outages in some areas.

Intense cold this weekend with powerful and potentially damaging winds…
The combination of a clipper low pressure system and its associated cold front will produce snow showers in the area late today and tonight and there can be brief heavier snow bursts. Small accumulations are likely on the order of a coating to an inch or two and there can be slippery spots on the roadways. After the passage of the cold front, an Arctic air mass will plunge into the Mid-Atlantic region from eastern Canada leading to a bitter cold weekend. This Arctic air mass is the real deal, had its origins on the Siberian side of the North Pole, and will not have the usual modifying effects of crossing over the relatively warm Great Lakes.

An Arctic air mass will plunge into the Mid-Atlantic and Northeast US this weekend moving almost directly southward from the frozen tundra region of eastern Canada. Actually, this incoming Arctic air mass had its origins several days ago on the other side of the North Pole and was transported into North America from Siberia in a “cross-polar” overall wind pattern. The cold front at the leading edge of this bitter cold air mass will be quite active with strong support in the upper part of the atmosphere. As a result, numerous snow showers are likely on Friday night, and there can be bursts of heavier snow mixing into the picture...small accumulations and slick spots on the roadways are on the table. In addition to the bitter cold this weekend, biting and potentially damaging winds will become a major factor with gusts to 50+ mph raising the prospects for power outages in some areas. The combination of bitter cold air and powerful winds will result in dangerously low wind chill levels from later Saturday to early Sunday with apparent temperatures well below zero at times in many areas.

An Arctic air mass is headed to the Mid-Atlantic region for the weekend with its origins on the Siberian side of the North Pole. This Arctic blast will be directly discharged to us from eastern Canada as compared with the more conventional “northwest-to-southeast” route that has air traveling over the Great Lakes meaning there will be less chance for modification. The cold front at the leading edge of this bitter cold air mass will be quite active from late tomorrow afternoon into tomorrow night with strong support in the upper part of the atmosphere, leading to snow showers and perhaps a heavier snow squall. Small accumulations of a coating to an inch or so are likely by later tomorrow night…watch for slippery spots. In addition to the bitter cold this weekend, winds will become a major factor on both days with gusts up to 50 mph producing dangerously low wind chill levels of below zero in many locations.

Our mild weather pattern will continue for the next several days with afternoon highs generally falling in the range of the low-to-middle 60’s. Looking ahead, the pattern will likely change during the early part of next week with more normal temperatures and the chance of precipitation will be on the rise.

The overall weather pattern remains on the cold side for another day in the Tennessee Valley, but big changes are on the way. It’ll turn milder on Friday with highs well up in the 50’s and then the 60’s are likely by Monday and Tuesday could feature highs near the 70-degree mark.
