Wind To Sweep Powerful Cold Front Into Middle Tennessee
Email Print
A powerful cold front will sweep across middle Tennessee this evening.

A strong low pressure center developing over Texas will continue strengthening as it tracks northeastward across west Tennessee today and into the Ohio Valley tonight. Middle Tennessee will experience mild temperatures again today as a strong south wind pumps warm, moist air into the mid state.

A cold front will sweep through middle Tennessee this evening, bringing widespread showers to the region, and also some thunderstorms. Some of the storms may become quite strong as winds aloft are brought down to the surface and result in gusty straight line winds.

Meanwhile, surface winds will increase as the low center edges closer to middle Tennessee. By late afternoon, south winds of 20 to 30 mph with gusts to 40 mph will be common in areas generally west of Interstate 65, and winds of this magnitude will spread across the rest of the mid state during the evening and overnight as the cold front pushes across the area.

You can expect temperatures to plummet behind the cold front, with most middle Tennessee locations bottoming out at or below freezing by daybreak Wednesday. Although the deeper moisture will pull out quickly once the cold front is past, light snow is still possible later tonight, with flurries continuing Wednesday morning in areas to the north and east of Nashville. No accumulation is expected.

Brisk winds will continue on Wednesday as a powerful Canadian high dives southward into the upper Midwest, with daytime temperatures remaining in the 30's across the mid state. Wind chills on Wednesday will remain in the teens and 20's, considerably colder than the mild weather middle tennesseans have enjoyed the last several days.

Wind Advisory remains in effect from 6 PM this evening to 6 a.m. CST Wednesday.

* Timing: Tuesday night.

* Winds: wind speeds of 20 to 30 mph with gusts to 40 mph.

* Impacts: high profile vehicles may become difficult to control.

Precautionary/preparedness actions...

A Wind Advisory means that winds of 25 to 39 mph and/or gusts of 35 to 57 mph are expected. Winds this strong can make driving difficult... especially for high profile vehicles. Use extra caution.
