Area Forecast Discussion
National Weather Service Nashville TN
556 PM CDT Sun Jun 25 2017




It was a beautiful summer afternoon with sunny skies, unusually
low humidity, and a north breeze. Temperatures were in the upper
70s to lower 80s. A broad upper trough was in place over the
eastern states, with dry surface high pressure extending from the
Tn Valley, all the way up to the northern plains.

For tonight, dry air and mainly clear skies will allow temps to
drop off into the 50s, or about 10 degrees below average. There
should be a pretty sunrise Monday with a few mid and high level
clouds moving in by daybreak. These mid and high clouds will
thicken and mix with sunshine through the day on Monday. The
cooler than normal air will be reinforced, with highs from the
mid 70s to around 80 and continued comfortable humidity levels.

Models continue to show a disturbance coming in from the
northwest Monday night into early Tuesday morning. The forecast
will continue to indicate 20-30 percent chance for showers. This
system will pass by Tuesday afternoon with sunshine returning and
still pleasant temps/humidity.

By Wednesday, the pattern will begin to change with the upper
trough starting to lift. Highs will warm well into the 80s and
humidity will begin to climb back toward typical summer levels.

Late week looks warmer, more humid, and unsettled as southerly
flow brings moisture into the area. There will be at least a
small chance for thunderstorms Thursday, then chances will climb
Friday and Saturday as the atmosphere becomes moist and unstable
ahead of the next wx system.



Broad upper troughing will be in place through the taf period.
Initially, skies will be mostly clear. However, a weak series of
mid level impulses will bring some mid level cloudiness to the taf
areas aft 12z.
