Not sure if severe thunderstorms can go in this thread but thought I’d share this from MRX of the 2020 Easter tornadoes in SE Tennessee. https://storymaps.arcgis.com/stories/55cc7aa49acc47839e8fa7010983ff83

For the first time in a long time I’m lucky enough to have a 2 mile wide streamer set up over me. The one going through Luttrell is 40 miles long. It’s almost a white out when you get under one of these.

Wow that’s awesome

MRX be like…….“we tried to tell you” @Holston_River_Rambler

Interesting little piece of energy rounding the base of the trough that’s headed towards ETn. It’s on the low and ML water vapor. Not sure it actually causes any lift but…. also the CAA behind the trough looks healthy and it looks like we will be really close to the right exit region. 500mb maps show some separation in the right exit region so diversion aloft may help some assuming the same effect that can increase thunderstorms can also aid winter weather.

A good example of what you are saying… both of these PWS are on the same time. One at my house, the other in NE Tenn somewhere on Roan Mt.

lol… figured out why it’s ripping it at my house while no one else is talking about it. This streamer has been sitting over me running SW to NE for the last 30 min. Streets are getting covered again.

I’m getting some pretty good high ratio rates right now and it’s a little bigger flake size than the normal NW flow stuff. Coming down pretty good.

It’s so hit or miss but 75% a miss. Most of the time we get down slopped bad unless the flow has a little more W to E direction in it. When the DGZ is lower, the problem is still there but not as bad.

I wasn’t trying to correct you. I’m not one of those.

If the DGZ is saturated and below 850, that will help the valley. A low and saturated DGZ tends to bank up against the mountains and backup into the valley but it takes a little time for this to happen. It basically acts like fog in the valley caused by an inversion. It can’t can’t go anywhere. A low DGZ also helps the down slope issues off the northern plateau into the valley. Getting interested now lol

what site is that? Link?

Looking at state wide totals and assuming qpf was the same, I don’t believe we had down sloping issues in the valley. Pretty much 2” state wide other than the Clarksville area. I haven’t seen anything from @John1122 Its possible he had 4 or 5 inches.
