A look at Tennessee. The area of dry conditions across West TN has now been removed from the map. Areas along the eastern edge of the plateau, however, remain in the “abnormally dry” category, as well as areas of extreme northeast TN.

A winter storm impacted areas from the northern Plains, to the Midwest, into the Southeast and then up the east coast during the period. For many areas, this was the first time that heavy snow occurred in these regions as many have brought up “snow drought” in areas of the country where snow has been minimal. From the Missouri River west, there was very little precipitation for the week. Temperatures were warmest over the northern Rocky Mountains and Plains where departures were 10-15 degrees above normal. Cooler temperatures dominated the East as departures were 5-10 degrees below normal.
Over the next 5-7 days, it is anticipated that cooler than normal conditions will dominate the eastern half of the United States, with the greatest departures along the Canadian border in the Great Lakes region where departures of 12-15 degrees below normal are anticipated. Warmer than normal conditions over the West and northern Rocky Mountains with departures of 6-9 degrees above normal could be observed. Some precipitation is expected over the Pacific Northwest and into the Rocky Mountains. The wettest locations are expected to be in the South and Southeast and into the Mid-Atlantic where up to an inch or more of precipitation could be expected.
The 6-10 day outlooks show the high probability of colder than normal temperatures over the eastern half of the country, especially from the Great Lakes to the Mid-Atlantic into New England. It is anticipated that below normal precipitation will impact much of the country centered on the Great Basin and the Midwest. There are above normal chances for above normal precipitation in much of Alaska, central Rocky Mountains and along the Gulf Coast.
