CLARKSVILLE, TN (CLARKSVILLE NOW) – Storms will hit Clarksville in two waves this weekend, bringing up to 2 inches of rain.

“A warm front will lift northward and stall just to our north tonight. As the boundary strengthens and encounters some increasingly unstable air, a few strong to severe thunderstorms will be possible,” particularly in the Montgomery County area, the NWS said.

High winds and small hail will be possible.

The first storm will hit between 9 p.m. tonight and 5 a.m.

Storms Saturday, snow Sunday

The second wave will reach Clarksville mid afternoon Saturday and continue into Saturday evening.

“Straight line damaging winds, large hail and a few tornadoes will all be possible,” the NWS said.

On Sunday, rain will change over to snow as colder air moves into the region.

“At this time, only very light accumulation is possible, mainly across the far north and along the Cumberland Plateau. Warm ground temperatures should prevent any major driving problems.”
