Rain changing to snow Friday PM?

Gulf low creates tricky forecast as usual!

Rain changing to snow Friday night

NASHVILLE, Tenn. Earlier in the week it looked like our “Gulf Low” would keep all its moisture to our south.

For folks wanting snow, this was a disappointment.

HOWEVER, newest model runs are showing precip making it farther northward, into Tennessee, first as rain during the day on Friday (possible mix on leading edge). See below:

Rain 6am-noon Friday

Rain could mix with some snow northwest/west late afternoon but temps above freezing. See below:

However, as the low moves farther east and colder air is pulled in behind it, we should see the rain change to snow after sunset Friday evening. See below:

The GFS model shows the back end of the precip ending as freezing rain between midnight and 6am, but that will likely be snow with a little freezing rain mixed in. See below:

As far as slick roads are concerned, the worst time period for that would be after dark Friday through around 10am Saturday morning, when some sun and rising temps improve things. Places like Clarksville, Dover, Paris, Erin, and Waverly could see deteriorating conditions earlier and the highest accumulations.

Accumulations: Too early to pinpoint, but could be 1-3″ northwest/west, dusting to 1″ Nashville, 1-2″ north and northeast/far east of Nashville, a dusting at most south of Nashville.

Of course, things could change, so we’ll keep you posted!
