for 18z aviation discussion.
Showers look to be mainly scattered through the day, with a few
echoes out there right now west of the Tennessee River and in southwest
zones. Better shot at precip will come this evening and especially
overnight as the upper shortwave approaches ahead of the main
trough. Temps are warmer this morning, especially for those few
areas that have seen the sun this morning. For now kept
temperatures from the previous forecast largely unchanged.
Adjusted pops to line up with latest cams. Rest of forecast looks

Chances for showers will increase today, along with dropping cigs.
MVFR cigs look likely late evening through the overnight, with IFR
cigs and vis possible with heavier rainfall. Rain will hold off at
kcsv until just before sunrise with vcsh nearby overnight. A break
in the rain will be possible Friday afternoon which may allow for
cigs to return to MVFR and possibly VFR in the afternoon, but rain
chances will return late Friday night. Southwest winds will be
around 10 to 15 knots during the day today and around 5 to 10
knots overnight and into the morning Friday.
