.DISCUSSION...

It was a nice afternoon with partly sunny skies and temps in the
60s. We are watching showers form back across Arkansas and
Missouri. The upper level low responsible for these showers will
zip eastward across Middle Tennessee late today and tonight.
Scattered showers are expected, mainly across the north half of
our area. The air at upper levels is just cold enough that a
rumble or 2 of thunder would not be surprising. Temps will fall
through the 50s this evening, and then down into the 40s by
daybreak.

Monday and Tuesday will be dry with temperatures warming both
days. Monday will bring highs in the 60s to lower 70s, then by
Tuesday afternoon, the majority of the area will be in the low to
mid 70s. An upper trough will approach Tuesday evening with a
developing surface low that will lift out of the bootheel of
Missouri toward the Ohio River Valley. This surface low will drag
a cold front through the area Tuesday night with light showers,
followed by quickly falling temperatures. Lows will dip into the
upper 30s by daybreak Wednesday. Clouds and sustained winds will
inhibit frost potential Wednesday morning. Even with partly sunny
skies on Wednesday, highs will recover only into the 50s.

Wednesday night will likely bring frost across the area, and brief
freezing temps in some spots. There is still plenty of time to
launch and frost/freeze headlines that may be required.

Temperatures will slowly climb Thursday and Friday ahead of the
next system. Frost looks possible again Friday morning, mainly
along the Cumberland Plateau. The next system looks like it will
bring showers late Friday through Saturday, but still no major
weather systems are in sight and thankfully no severe wx.
