Severe Thunderstorm Warning 73, NWS Huntsville, AL

...New AVIATION...

.NEAR TERM...
(Rest of Today)
Issued at 958 AM CDT Fri Jun 17 2022

The main change in the near term forecast is a severe
thunderstorm watch has been issued until 2pm for southern Middle
Tennessee. A downstream watch into Alabama may be needed in a
later update. A MCS is pushing south across Tennessee as of 15z
and will continue to move southeastward towards the forecast area
later this morning into the early afternoon. Latest radar
observations indicate a weakening trend over the last hour or so,
especially on the western flank. However, new cells are developing
along an outflow boundary across north central Tennessee.

Overall, the parameter space across southern middle Tennessee and
into northern Alabama is quite favorable for strong to severe
storms. Forecast soundings indicate over 3000 J/kg of SBCAPE as
well as an inverted V shape. PW is between 1.5 to 2 inches.
Therefore, the main concern with storms this afternoon will be
damaging winds and locally heavy rain. The main uncertainty in
this forecast is the exact tract the MCS takes as it pushes
southeast. CAM guidance has been useless this morning as all of
them attempt to wash out the convection across Tennessee. While
the main MCS may miss the area as it takes more of an eastward
track, the new storms along the outflow to the south should
continue to strengthen as it pushes towards the local forecast
area.

Clouds and rain from the upstream MCS may limit heating this
afternoon, but have opted to leave the heat advisory in place as
heat indices are already in the mid to upper 90s.

.SHORT TERM...
(Tonight through Sunday night)
 Issued at 123 AM CDT Fri Jun 17 2022

Lingering thunderstorms will be possible into early this evening
as a cold front drops south into the area. Whether the loss of
heating diminishes the threat completely is uncertain however.

On Saturday, a nice reprieve from the heat wave is expected with
highs in the upper 80s to lower 90s, with lower dew points. Dew
points may drop into the middle 50s northeast and lower 60s
southwest during the afternoon hours. Morning lows on Sunday will
dip into the upper 50s in southern TN and northeast AL, with lower
60s elsewhere. Once again, highs in the upper 80s to around 90 are
expected Sunday afternoon.

&&

.LONG TERM...
(Monday through Thursday)
Issued at 123 AM CDT Fri Jun 17 2022

The 5h anticyclone will be situated and strengthening again over
the mid South and lower MS valley early next week. Temperatures
will warm back into the lower to middle 90s Monday, then upper 90s
Tuesday, then upper 90s to around 100 Wednesday and Thursday. The
good news is the air will not be atrociously muggy, with dew
points mainly in the lower 60s during the peak heating hours of
the afternoon. The lack of widespread rainfall will also
contribute to the lower evapotranspiration into the boundary
layer. At this point, a dry forecast is indicated through at least
Wednesday. With the upper high starting to break down some by
Thursday, we may need to introduce a low PoP in down the road, but
for now kept it dry until this becomes more certain.

.AVIATION...
(18Z TAFS)
Issued at 1212 PM CDT Fri Jun 17 2022

VFR conditions will be predominant for the majority of the period.
The one exception will be as a line of storms pushes south, which
is at the AL/TN state line at the start of the period.
Thunderstorms will move over the terminals early this afternoon,
gusty winds and lower visibility is expected. VFR returns once the
storms pass south of the terminals and continue through the end of
the period.
