Another widespread cold air mass will impact the Tennessee Valley over the next few days as high pressure builds to the southeast from Canada. Highs today will struggle to reach the mid 40’s and there will be a noticeable wind chill caused by 10-15 mph NW winds. As the high pressure edges closer to the region, the cold blast will become even more noticeable as temperatures tonight will drop way down into the 20’s and struggle to reach the mid 30’s on Friday – normal high is now around 52 degrees.

Despite the fact that it’ll turn unseasonably mild later tonight and early Thursday in much of the eastern US, the overall cold weather pattern shows no signs of slowing down. There will be another outbreak of cold air in the eastern US for the Thursday night/Friday/Saturday time period, but the coldest core of that air mass (relative-to-normal) will be centered over south-central and southeastern Canada. Next week, however, it looks like a brutally cold air mass will plunge southward right into the central US and eventually make its way to the east coast - and the coldest temperatures relative-to-normal will be in the US.

There will be occasional showers today ahead of an approaching cold frontal system and an outside chance at a thunderstorm. Colder air arrives tonight following the passage of the cold front and skies should clear for Thursday and Friday as high pressure builds back into the region.

After a very cold day to start the week, it’ll turn milder ahead of the next low pressure system and the winds will pick up in intensity out of the southeast. Showers are likely by early tonight and the threat will continue through mid-week. Colder air will follow for the latter part of the week and snow showers will be possible each day as we head towards the weekend.

Very cold air poured into the eastern US this weekend and we’ll start the week on a cold note in the Tennessee Valley. It’ll stay rain-free for today and at least the first part of tomorrow, but a storm will be intensifying as it moves eastward from the middle part of the nation. Rain is likely to push into the local region by mid-week and there could be a decent amount as this system has quite a bit of upper-level support.

Strong low pressure will head right towards the Tennessee valley early this weekend and then to the Mid-Atlantic coastline by early Sunday. Given this track, it should turn noticeably warmer around here on Saturday, but then much colder on Saturday night and Sunday following the passage of a powerful cold front that sweeps through here on the back side of the departing low pressure system. High on Saturday ahead of the front are likely to be in the 60’s and then confined to the 30’s to close out the weekend.

It’ll turn milder over the next couple of days, but the end of the warming trend is already in sight as a powerful cold front will sweep through the area this weekend. In fact, the weather on Saturday will become quite active for the eastern third of the nation as a strong cold front slowly works its way to the eastern seaboard. Rain is likely here on Saturday and there can be a thunderstorm or two and it’ll become quite mild. On Sunday, however, the temperatures are likely to plunge on the back side of a departing strong low pressure system and the fresh batch of Arctic air will keep us well below-normal on Monday as well as begin the new work week.

A cold and stormy weather pattern is getting locked in for the eastern US and there may be three different systems to deal with over the next week or so. On Thursday, low pressure will head in this direction from the Ohio Valley and likely produce some snow around here on Thursday night. A much more significant storm is going to impact the I-95 corridor this weekend and everything is on the table for this event including rain, ice and/or snow. It is still too early to determine the magnitude of each precipitation type for the DC-to-Philly-to-NYC corridor, but accumulations of ice and snow are on the table. In addition, as the weekend storm pulls to the northeast later Sunday, Arctic air will flood the Mid-Atlantic region and any precipitation that lingers can change to ice and then snow before ending. Also, as temperatures plunge late Sunday, a “flash freeze” is possible in some areas with a quick ice up on roads, etc. The coldest air mass of the season so far will likely result in single digit lows in parts of the region by early Monday morning and highs may be confined to the teens to start the new work week.

It’ll be another chilly day in the Tennessee Valley with high confined to near 50 degrees, but a warming trend begins later this week. The weekend will become quite active for the eastern third of the nation as a strong cold front slowly works its way to the eastern seaboard. Rain is likely here on Saturday and there can be a thunderstorm or two and it’ll become quite mild. On Sunday, the temperatures are likely to plunge on the back side of a departing strong low pressure system and the fresh batch of Arctic air will keep us way below-normal on Monday as we begin the new work week.

It’ll be another chilly day in the Tennessee Valley with high confined to the 40’s, but a warming trend begins at mid-week. In fact, by Thursday and Friday temperatures should climb well into the 50’s and there will be an increasing shot at some shower activity. The weekend will become quite active for the eastern third of the nation. A strong cold front will slowly grind its way through the eastern states and low pressure will ride along its boundary zone. The result here is likely to be periods of rain on Saturday followed by much colder conditions for Sunday and Monday. The transition from the mid, rain on Saturday to the big chill down for early next week could be accompanied by some ice or snow.
