Mesoscale Discussion 0213
NWS Storm Prediction Center Norman OK
0651 PM CDT Tue Apr 03 2018

Areas affected...Western and middle Tennessee into northern
Mississippi and northwestern Alabama

Concerning...Severe potential...Watch likely

Valid 032351Z - 040145Z

Probability of Watch Issuance...80 percent

SUMMARY...Thunderstorm activity accompanied primarily by a risk for
potentially damaging wind gusts will overspread the region through
the 9-11 PM CDT time frame.

DISCUSSION...A broken pre-frontal line of thunderstorms is in the
process of progressing east of the Mississippi River, where the
boundary layer remains drier with dew points generally in the
lower/mid 50s. With an upstream cold front continuing to surge
through what is left of a plume of higher surface moisture content
near/west of the Mississippi River, little further low-level
moistening seems likely prior to the passage of the convective line
(aside from from some surface dew point increases with the loss of
daytime heating/mixing). It is possible, though, that present weak
instability and forcing for ascent may be enough to maintain fairly
vigorous convective development into the 02-04Z time. As long as
storms maintain some strength, in the presence of 40-50 kt deep
layer mean flow, a risk for potentially damaging wind gusts will
probably continue.

If the reports right now are any indication this is going to end up as an insane wind event. I agree with what Rolltide said, it may end up being another 4/4/11, although at the moment there appear to be more hail than wind reports.

The hail threat will begin to diminish compared to the wind threat as anvil seeding takes over. This will likely go full derecho.

Been using Radarscope for years. I'm happy to pay the $10 for the app and the yearly fee because it's a great app. Not going to dish out the $100/yr for the tier 2 pro thing though.

I use Radarscope on my phone and tablet as well. Love the app especially when I am on the move.

Thankfully, this way underperformed for the Memphis metro. Nothing but heavy rain and some awesome displays of lightning. There were much heavier storms north and south, but I haven't seen too many damage reports except around the Jackson, TN coverage area.

Bluff City dodged another bullet - I just hate that it's more likely to make people complacent in the future, especially with the chatter of an active pattern next week....

Line in MS appears to be very robust with many damage reports around the AR/LA/MS border area. Still getting 4/4/11 flashbacks; really hope it doesn't get as bad here now as it did back then, but the warning train marches east.

Velocities associated with that line is nuts. Damage reports still rolling in.
