.DISCUSSION...

Pattern is rather non progressive at this time. However, we will see
more in the way of stacking in terms of the lower and mid level
trough patterns across the area today. Upper low over IN will deepen
a bit more this afternoon as compared to yesterday. Height values
and mid level temps will be a touch cooler as well. This all equates
to better areal coverage for the mid state today. Pops will range
from 60 percent northwest up to 80% southeast.

We finally see some form of pattern progressiveness tonight as the
trough axis shifts eastward. Relatively drier air will then work in
and we will see our pops drop tonight. The surface trough to our
east on Saturday will slow down with perhaps some weak convection
mainly over the Plateau. Saturday night is looking pop free although
a frontal boundary will be lurking upstream. This cold front will
move through on Sunday. Winds in advance of the feature still
looking light northerly in advance of it and thus forcing looks
weak. Nevertheless, pop inclusion to the tune of 20-30 percent will
be sufficient. Overnight patchy fog will still be an ongoing
possibility through Sat nt.

For the near term temps, Looking a little above normal on Saturday
and Sunday as higher heights welcome the approaching front.

In the ext fcst, sfc high pressure will attempt to build southward.
But the boundary to our south will have limited southward movement
as an upper trough axis camps out across the southeastern US.
Moisture return is looking limited. Low 20-30 pops will  be
included, with the best chance over the Plateau.

For the ext temps, max temps will still be in the mid to upper 80s
but humidity values will be lower. Dewpoints should hold in the 60s.
Overnight lows look like mid 60s for the most part.

Upper shortwave axis will remain in close proximity for one more
day across middle TN. With heights and mid level temps a little
cooler today, look for more widespread shower and tstm coverage
by this afternoon. The shortwave will begin to pull out tonight
with lowering rain chances thereafter.
