The overall weather pattern will remain quite cold in the Tennessee Valley through the upcoming weekend. In fact, this unusual chill down is quite widespread across the nation with below-normal temperatures virtually extending from coast-to-coast. A reinforcing cold air mass has arrived here and today’s temperatures will be nearly twenty degrees below-normal for this time of year.

Temperatures across the nation this morning averaged out to an impressive reading of nearly 12 degrees (F) below-normal for mid-November and no state in the Lower 48 escaped the colder-than-normal chill. The first widespread snow event of the season took place late yesterday in the interior, higher elevation locations of the Mid-Atlantic/Northeast US with half of foot of snow recorded in some areas. The next few days will feature a “Great Lakes snow-making machine” that will be turned on in full force and the result may be several feet of snow in some downstream locations such as Buffalo and Watertown in western New York. The nationwide cold will continue right through the upcoming weekend.

The overall weather pattern will remain quite cold in the Tennessee Valley through the work week and also right through the upcoming weekend. In fact, this unusual chill down is quite widespread with below-normal temperatures virtually extending from coast-to-coast. A reinforcing cold air mass will arrive here tonight and Thursday with the lowest temperatures of the season so far for the northern part of Alabama.

This “middle” week of the month of November could turn out to be one of the coldest in a long, long time for the nation as a whole with virtually coast-to-coast colder-than-normal weather conditions. There was a smattering of low temperature records set this morning across the central and western US and numerous records are likely to be set later this week and weekend; especially, across the central states where temperatures could drop to as much as thirty degrees below normal for this time of year.
In terms of snowfall in this unusual early season cold wave, it looks like the first widespread snow of the season will take place from later today into early Wednesday across interior, higher elevation sections of the Mid-Atlantic/Northeast US. Later this week, an intense Great Lakes snow event will kick into gear with paralyzing amounts of snow possible in some spots such as Buffalo and Watertown in western New York.

The overall weather pattern will remain quite cold through the week and also upcoming weekend in the eastern part of the nation. A fast-moving wave will bring more rain showers here this morning and then chilly high pressure will take back control of the weather for the second half of the week.

At the same time Tropical Storm Nicole was pounding Florida on Friday with rain and wind, a blizzard was raging in the Northern Plains where two feet of snow piled up in such places as Bismarck, North Dakota. That late week cold air mass situated in the Northern Plains subsequently made its way into the northeastern US following the departure of Nicole to the open waters of the Atlantic Ocean. The exit of Nicole helped to bring about a change to the overall upper air wind pattern across North America. In fact, not only has the eastern US chilled down during the past 24 hours, virtually the entire nation is now featuring colder-than-normal temperatures and will likely do so right through the weekend. By the end of the week, many low temperature records will have been broken; especially, across the center part of the nation and every state in the Lower 48 can experience below-freezing temperatures.
In terms of snow potential, a coastal low will intensify by tomorrow night just off the Mid-Atlantic coastline resulting in a cold, soaking rain in the immediate I-95 corridor and to coastal sections, but the first accumulating snowfall of the season is likely in many of the interior, higher elevation locations across the northeastern states. The chill may ease up for awhile later next week, but there are signs for a resumption of the cold pattern going into late November and December.

At the same time Florida was getting hit by Tropical Storm Nicole on Friday, two feet of snow was falling on Bismarck, North Dakota and that cold air mass has pushed into the Tennessee Valley. There will be, however, some moderation in temperatures today as high pressure pushes to the east allowing for a low-level flow from a southerly direction to form. A fast-moving wave will bring some rain showers here by tomorrow and then chilly high pressure will take back control of the weather for the second half of the week.

Nicole climbed to category 1 hurricane status late yesterday and came ashore in the overnight hours near Vero Beach in east-central Florida. After landfall, Nicole has weakened slightly back to tropical storm status and will become increasingly influenced by a deep upper-level trough over the north-central states that is contributing to blizzard-like conditions in the Upper Midwest/Northern Plains. The remains of Nicole will ride up along the spine of the Appalachian Mountains over the next 24-48 hours resulting in a significant rain and wind event all the way from Florida-to-Maine. On the east side of the expected storm track, severe weather will be a possibility including the threat of isolated tornadoes. The passage of the tropical storm will be part of an overall significant temperature pattern change in the central and eastern US that will bring much colder weather conditions for the remainder of November.
