Discussion...surface analysis this evening places a ridge of high
pressure over the Mississippi Valley. This is resulting in mostly
clear to clear skies across the mid-south. As of 8 PM CDT,
temperatures across the forecast area are in the 50s across many
locations except across west Tennessee near the Tennessee River
where temperatures have already fallen back into the middle 40s.
Current frost advisory headlines seem reasonable given current
trends as overnight temperatures across this area are anticipated
to fall back into the middle 30s. No updates planned at this
