~Severe Weather Alert~
There is an Enhanced risk for strong to severe thunderstorms in the Plateau. There’s a Slight risk for all other areas in East TN.
Timing: Overnight into Thursday morning.
Hazards: The primary threats are damaging winds in excess of 60 mph and large hail to quarter size. An isolated tornado or 2 can’t be ruled out.
VK’s thoughts:
More often than not, when a front is rolling through our area during this timeframe, the instability isn’t that strong due to no daytime heating. However, it appears that all of the dynamics (instability, wind shear, etc) will be fairly strong with this system. Because this will be occurring while everyone is asleep, people need to either have their weather radios charged up or have the warning alerts on their phones turned on.

Update:
Almost all of East TN (excluding far northeast TN including the tri-cities) has been upgraded to an Enhanced risk for severe storms overnight into tomorrow morning. The damaging wind threat is looking to become more widespread. The hail and tornado threat remains the same, although I would not be surprised if a few isolated areas saw large hail to half dollar size.
P.S. I almost forgot the following. There is a chance that we could see destructive winds up to 80 mph.

Meant to add this a bit ago.
Mesoscale Discussion 0320
NWS Storm Prediction Center Norman OK
0952 PM CDT Wed Apr 08 2020
Areas affected...middle and eastern Tennessee...far northern Alabama
and Georgia
Concerning...Severe potential...Watch likely
Valid 090252Z - 090445Z
Probability of Watch Issuance...80 percent
SUMMARY...Severe storms may eventually affect areas east of Tornado
Watch 92, and a new watch is likely. Damaging winds appears to be
the primary threat, but a tornado is possible.
DISCUSSION...An unstable air mass resides across the region this
evening, with ample deep-layer shear favorable for
sustained/organized storms. Currently a line of storms is moving
east/southeast across Middle TN, likely with damaging wind gusts.
Downstream areas will likely require a watch soon as the environment
is supportive of a continued threat. In addition, isolated cells
cannot be ruled out as capping is minimal, and lift will persist
through early tonight.

Good morning, everyone. I’ve been doing some thinking, and just like the NWS SPC gives out risk categories to outline how bad the severe weather will be in an area, I’ll be doing the same on my pre-storm write-ups. Here is my scale.
Severe Weather Bulletin: I’ll put this whenever the severe threat is marginal/isolated. It’s not something to ignore or to panic. It’s just a heads up that a few areas might see a strong to severe thunderstorm.
Severe Weather Alert: I’ll post this whenever there is a decent to really good chance for a large part of East TN to see strong to severe storms. I’ll generally post this whenever there’s a Slight Risk for our area (and Enhanced in some situations).
Severe Weather Outbreak: This is one that I pray I rarely ever have to use. I’ll only post this in the case where widespread significant severe weather is likely. Generally, I’ll put it down if we’re in an Enhanced risk with a hatched area, Moderate, and High.
One other note: There is a special classification that I will use in certain situations. For example, if our area is in a Slight risk for strong to severe thunderstorms and there is a hatched area for significant wind, hail, or tornado, then I’ll put (hatched) next to the Severe Weather Alert.
