Tennessee Valley New Year’s Eve

Posted on: 5:40 pm, December 31, 2012, by

If you have New Year’s Eve plans, take your umbrella! The chance of rain rises quickly between 6 PM and Midnight. This is the approximate chance of rain across the Tennessee Valley this evening up until the ball drop at Big Spring Park:

While that looks scary, it will not be very heavy rain early on! That is the chance of at least enough rain to measure (0.01″). The chance of “significant” rain is much lower; in fact, we only expect a total of about 0.01″ to 0.10″ of rain through midnight in Huntsville, Decatur, Athens, and Cullman. In The Shoals, it will be somewhat wetter with rainfall amounts already exceeding 0.10″ by midnight.

If you are attending a fireworks show (or producing your own), don’t worry too much about getting totally rained out east of Interstate 65; the rain will be light and spotty through midnight east of I-65. To the west, it will be a more persistent rain around Florence, Muscle Shoals, Russellville, Waynesboro, Lawrenceburg, Hamilton, and Double Springs between 8 PM and 12 AM.

The chance of rain climbs to 100% overnight. This is the probability of getting more than 0.01″ of rain between midnight and 6 AM on New Year’s Day:

In all, a band of heavier rain will likely set up south of the Tennessee River dumping as much as two inches of rain in Marion, Winston, Walker, Fayette, Cullman, Blount, Morgan, Marshall, Etowah and western DeKalb County. No severe weather is expected; in fact, the chance of lightning is very low. We do not expect a major lightning hazard outdoors tonight:
