Now getting word from sources. Gravity waves being detected around west and middle Tennessee...

I looked it up on Wikipedia but can someone explain what a gravity wave being detected means in the context of today’s weather? Thanks!

Yes, gravity waves can be a clear indication that the atmosphere is beginning to juice up and destabilize. We just studied these last week in class. This could also be an indication of a warm front pushing through or approaching. These clouds do not mean you are guaranteed severe weather, but they do mean weather changes are coming in your immediate future.

Totally getting crapvected at the moment. HRR clears it out in an hour. QLCS looks to form well back into Arkansas now and into the Memphis area around 7.  Cape should increase after this moves out. Cape down into the MS delta looks more stout than here.

Unfortunately for those in eastern areas, the rough weather looks to move in overnight.

Quote
As the night wears on, this severe convective line will move out of
the Plateau into east TN, generally around the 3-6AM timeframe.  At
that point the atmosphere across east TN and southwest NC/VA will
still be supportive of severe convection, therefore little if any
weakening is expected,
with any weakening being furthest north.  A
strong 60-65kt swly llj will move across the region with (and ahead
of) the convective line, which will enhance shear/srh to levels
favoring damaging winds and perhaps an isolated tornado or two.  The
highest chances for tornadoes will coincide with the region of best
shear/instability overlap, which looks to remain along/west of I75
and along/south of I40
.  Further east/northeast surface based
instability will be at a premium, thus tornadoes are less likely.
Overall the greatest threats will this storm system will be damaging
winds, isolated tornadoes, and brief heavy rainfall.
  Further timing
details would suggest the strongest portions of the line moving into
CHA by around 3-4AM, TYS at around 4-5AM, and TRI by around 6-7AM
(albeit weaker that far north).
