Area Forecast Discussion
National Weather Service Nashville TN
859 PM CST Sun Jan 22 2017




Updated various elements this evening to match current obs and
trends. Surface low is just off to the southeast of the area, and
looks to slowly travel eastward across northern GA tonight and
during the day Monday. Model consensus has best chances for precip
over the Plateau and southeast counties through the overnight
hours, with some trailing showers possible rotating around the
surface low for the rest of the area. Rain chances will linger
into the morning hours and possibly into the early afternoon but
mainly be confined to the east as the upper low moves towards the

Models also want to ramp winds up overnight with the surface
pressure gradient strengthening after 06Z through 12Z. Put in
sustained winds 15 to 25 mph and gusts to 35 mph mainly across the
I-65 and I-24 corridors. Winds look to peak around daybreak and
start calming down through the day on Monday.



Strong upper level low to the SE of Middle TN is going to continue
to affect our mid-state terminals throughout the night. KCSV is
likely to get the worst of it tonight with IFR to LIFR conditions
expected to settle in after 03Z. KCKV and KBNA should only see
MVFR after 06Z tonight.

The biggest story is likely to be the wind. A strong northerly
wind will kick up this evening with sustained winds of 15-20 kts
and gusts close to 30 kts. These winds are expected to persist
throughout the overnight hours and while they`ll relax a little in
the morning, it will still be breezy with a little more of a
northwesterly fetch.
