Area Forecast Discussion
National Weather Service Nashville TN
657 PM CDT SAT SEP 24 2016




It`s been another hot September day in Middle Tennessee. Latest
observations are reporting mid to upper 80s along the Cumberland
Plateau and up to 91 degrees around Nashville. The record high for
today is 94 in Nashville and 88 in Crossville. While both records
are within reach for today, we`re still forecasting temperatures
to fall short a degree or two. Weather will remain dry for at
least the next 24 to 36 hours with Sunday`s high temperatures
similar to today`s. High pressure will erode during the day
tomorrow and give way to an upper trough digging across the
northcentral U.S.

The frontal boundary associated with the upper level system
should make its way across the Tennessee River Monday morning and
then continue through Middle Tennessee and off the Cumberland
Plateau Monday afternoon and evening. A round of showers and
thunderstorms will accompany the front. Not expecting too much
precip from this system as it should move through fairly quickly.
Widespread rainfall amounts around 0.10 to 0.20 of an inch are
expected with some places seeing slightly higher amounts. Now for
the news everyone has been wanting to hear: this upper low will be
responsible for a long awaited cool down this week! We should
begin to feel this on Monday as temperatures will likely only rise
into the low to mid 80s. Low temperatures Monday night are
expected to be in the mid 50s.

After the front exits the area on Monday night, drier air will
fall in behind it and a predominately north surface flow will set
up for the remainder of the work week. Expect daytime highs to
only reach the mid to upper 70s from Tuesday through Friday with
no precip in sight. Low temperatures will fall into the 40s for
much of the area on Wednesday night, then rest in the 50s for the
remainder of the week.



The few clouds that existed at 00Z will end quickly, leaving clear
skies across the region overnight through at least the morning on
Sunday. Lone exception is the potential for patchy fog to develop
for a couple hours around sunrise Sunday. Should be similar to
what happened this morning so decided to leave it out of BNA/CSV
but included it at CKV due to their recent past. Expect light
north winds or variable winds through the period.
