555 PM CDT SAT AUG 27 2016




Showers and thunderstorms have developed this afternoon thanks to
upper shortwave activity moving around the upper high as well as
diurnal support. Activity looks to continue through the afternoon
and even into the evening hours before settling down overnight. A
similar pattern for tomorrow looks to have chances for precip
during the day, and higher chances exist east of I-65.

By Monday the upper high moves eastward but is quickly replaced by
another high later in the day. With that pattern in place, again
shortwave activity combined with diurnal help will again bring
chances for showers and thunderstorms mainly Monday afternoon. A
bit of a drier period moves in Monday night through Tuesday night
as the large upper ridge over the Plains begins to track eastward.
There will be some slight chances for precip on the Plateau
Tuesday and maybe along the TN River Valley, but otherwise models
look to keep the mid state dry.

Wednesday looks to have the ridge a bit further east, bringing
northwest flow aloft over the eastern CONUS. This will allow
shortwave activity to bring some chances for showers and
thunderstorms during the day Wednesday and Thursday. Chances look
a bit less than yesterday`s forecast, but still enough to have
mention of chance and slight chance in the grids. Friday and
Saturday look to be mostly dry as the upper ridge builds in, but
Saturday afternoon may have some chances for precip on the Plateau
with some weak shortwave activity.

With upper highs and ridging dominating the next week or so,
temperatures look to remain consistent with highs in the low 90s
and lows in the low to mid 70s. The only exception will be
Thursday and Friday night where model consensus has lows in the
mid to upper 60s returning to the mid state.



BNA/CKV/CSV...Storms appear to be dissipating, with only isolated
showers around for the evening, then dry overnight with some
radiation fog after 06Z. Look for isolated/scattered convection
again tomorrow afternoon, and will handle this with vicinity
remarks for now.
