.SHORT TERM...
(Today through Tuesday)
Issued at 153 AM CDT Mon May 20 2024

Upper level ridge will continue to build over Middle TN for the
start of the week and that will bring quiet and warm weather for
us. Highs will be warm once again with them reaching the mid to
upper 80s for the afternoon. CAMs do want to bring some widely
scattered popup showers over the Plateau this afternoon but
soundings show strong substance and these shower chances seem
unlikely but afternoon clouds are likely. As for fog early this
morning, with slightly drier dew points tonight it should not be
as widespread as last night but we still could see some develop in
the river valley`s and fog prone areas. Upper level ridge will be
overhead on Tuesday with more of the same, dry and warm with
highs in the 80s to near 90.

.LONG TERM...
(Tuesday Night through next Monday)
Issued at 153 AM CDT Mon May 20 2024

Upper level ridge will push east for the extended period and we
will start to see shower and thunderstorm chances return to the
forecast. An upper level trough and surface low will push through
the Great Lakes Wednesday and into Canada on Thursday. This will
push a cold front into the area late Wednesday into Thursday. The
front will be weakening as it pushes into Middle TN and overall
that will limit the forcing with it but we will still see showers
and thunderstorms with it. CAPE looks to be 500-1000 j/kg and 0-6
km shear will be marginal for more organized convection but with
the weaker forcing the severe threat is overall low. If we were to
see any stronger storms wind and hail would be the threats along
with heavy rain.

The front will stall out over the region on Thursday with a short
wave pushing east over us. This will keep showers and thunderstorms
in the forecast. The front will lift north as a warm front on
Saturday. We don`t see any strong forcing over the weekend but
with the unstable atmosphere shower and thunderstorm chances are
going to remain in the forecast.

Temperatures will cool back into the lower 80s Thursday and Friday
and will warm back into the mid to upper 80s over the weekend.

(06Z TAFS)
Issued at 1231 AM CDT Mon May 20 2024

Weak ridging will allow for clear skies and calm winds at all
sites for most of the period. Light fog may cause visibilities at
CSV and SRB to fall into MVFR territory in the early morning
hours. Any fog should burn off quickly after sunrise. Winds will
be light and out of the south and southwest throughout the day
today.
