Area Forecast Discussion
National Weather Service Nashville TN
701 AM CDT SUN JUL 24 2016




Air mass remains moist and unstable with little in the way of a
trigger to be found other than afternoon heating and lurking
outflow boundaries. Complex well to our north near Chicago will
work east along stationary frontal boundary next several hours.
Upper ridge sprawled from plains eastward across our area will
begin to retrograde today allowing for troughing to develop over
eastern U.S. This will allow a weak surface front to move this way
and by 12z Monday be down into southern Illinois. This will
increase thunderstorm chances beginning Monday and continue
Tuesday followed by a series of mid and upper level short waves
that will traverse the area beginning mid week and continuing
right into the weekend. So basically have thunderstorm chances in
the forecast through the work week and into the upcoming weekend.

Another hot day today with heat index values in excess of 100 west
of the plateau with values around 105 in the advisory area. With
more widespread thunderstorms this week afternoon max temperatures
will back off a few degrees from previous days but still at or
above climatology while night time lows will average about 5
degrees above climatology.



Repeat of yesterdays weather in play today as the mid-states
airmass remains moist and unstable. Scattered thunderstorms again
expected to breakout...mainly in the afternoon and early eve. Have
only included vicinity at this time. Later tonight...light fog
again possible, largely ckv/csv.


Heat Advisory until 8 PM CDT this evening FOR Cheatham-Dickson-
