East Tennessee Plays Catch-Up

Current weather predictions aside, East Tennessee is in the midst of the historically dry months. September, October and November are typically the driest months in the Tennessee Valley. During this time, the annual average runoff, which is the amount of water that washes into the local rivers following a rain event, is only around one inch. December, July and March are generally the wettest months and runoff in March can average 4 inches or more. Because runoff is generally greater in the vegetative off months of winter and early spring, these are considered the flood season in East Tennessee.

As with many things, location is everything and it may come as no surprise that East Tennessee has the most extremes. Annual rainfall amounts have ranged from only around 30 inches to over 65 inches. Predictions for the next few days are calling for precipitation and a possible storm event early next week that will usher in significantly cooler temperatures. The local area is running around ¾ of an inch behind in precipitation for October, however that could change if the extended forecast holds true. Four of the next five days are expected to bring wet weather to the region.
