...Freezing Temperatures are Forecast Tonight in Middle Tennessee...

A hard freeze is forecast tonight in Middle Tennessee, with lows
by sunrise Sunday expected to be in the middle 20s. If you happen
to have sat any tender plants outside to soak up the sun over
these recent warm days, you should bring them indoors this
evening before the temperatures fall to freezing.

It`s just a one night freeze, though, because lows by Sunday
night will be back above the freezing mark.
