Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Nashville Tennessee
1249 PM CDT Sat Jul 30 2016
for 18z aviation discussion.
Latest hrrr shows cluster of morning showers and thunderstorms
pushing steadily into southwestern middle Tennessee late this
morning, then weakening and falling apart. As a result, will
increase pops to likely over the extreme southwest and increase
nearby chance pops as well for late morning. If showers and storms
hold together longer than currently expected, may need to increase
pops over other parts of southern middle Tennessee for this
afternoon as well.
Have updated suite of products to reflect these changes.
Otherwise, little change to previous forecast.
18z taf discussion.
Expect isolated to scattered thunderstorms to develop this
afternoon across middle Tennessee, although forecast coverage is
not sufficient to warrant a mention in tafs at this point.
Otherwise, expect VFR conditions to prevail into the evening hours
at area terminals except for, perhaps, a few brief periods of
MVFR this afternoon due to ceilings. Look for patchy br and low
cigs, ranging anywhere from 200 ft to 1100 ft, to develop between
05z and 09z. However, cigs and vsbys should return to VFR by
