for 00z aviation discussion.



Currently...a weak cold front is pushing through middle Tennessee.
No big changes with this feature besides a wind shift and drier
air working into the area. Dewpoints have dropped into the lower
40s across the northern counties while dewpoints are still in the
lower to mid 50s across southern middle Tennessee. Skies are clear
with temps in the mid to upper 70s across the region this

High pressure will build in tonight and Tuesday. Clear skies and
light northeast winds will result in seasonably cool temps in the
40s tonight. Another beautiful day on tap for Tuesday with plenty
of sunshine, light east winds and just slightly cooler
temps...mostly in the 70s. By Wednesday the surface high will
shift east and a system will begin to approach the region. Winds
will turn southerly with temps getting close to 80 in many areas.

A progressive mid level trough and associated cold front will
swing through Wednesday night and early Thursday. Best chances for
rain will be across the Cumberland Plateau region late Wednesday
night. 12z models are picking up on some, albeit still marginal,
moisture return into the Cumberland Plateau region as the front
approaches. Went slightly high pops across the plateau with lower
pops toward the west including Nashville and the Tennessee River
valley. That being said this system still look like a meager rain
producer overall with quantitative precipitation forecast amounts remaining below a quarter inch.
Given the lack of instability and the main upper support remaining
well north decided against mentioning thunder for now. Any
lingering rain across the plateau early Thursday will end and
skies will being to clear as the trough exits.

A broad upper ridge will nose in from the west with the above
normal temperatures for Friday and Saturday. A weak cold front
could bring a few showers to the northern plateau on Saturday.
High pressure and slightly cooler weather expected for the latter
half of the weekend.
