And I admit I have concern for the Gadsden area later this evening as that monster cell to their nw moves se along the warm front boundary.

As if we need training west to east tornadic supercells with good inflow from the south.

I am assuming that the atmosphere is capped south of the present storms in northern Alabama and might unzip later as the LLJ increases and more forcing occurs.

Hackleburg and Phil Campbell potentially under the gun once again as in 2011.

Russellville Alabama is just under 10,000 population.

Funnel cloud reported by spotters east of Baldwyn MS.

550/350 m2/s2 helicity in the area of that tor warned initial cell in ne MS. We are off to what might be a very dangerous evening.

90/80 probabilities for tornadoes on the PDS watch.

Mesoscale Discussion 0146 NWS Storm Prediction Center Norman OK 0206 PM CDT Mon Mar 19 2018 Areas affected...Northeast MS...Northern AL...Southern TN Concerning...Severe potential...Tornado Watch likely Valid 191906Z - 192030Z Probability of Watch Issuance...95 percent SUMMARY...Tornado watch will be issued by 21z across portions of the Mid-South. A few strong tornadoes are possible in addition to large hail. DISCUSSION...Leading edge of mid-level drying/cooling is progressing across the MS Delta region at roughly 35kt. Over the next few hours lapse rates should adjust across western TN/northeast MS and deep convection is expected to expand in response to this feature. Conditions are becoming increasingly favorable for strong supercell development as boundary-layer moisture is advancing into northern MS/AL with mid 60s surface dew points now evident at TUP into Winston county AL. Early-day thunderstorm cluster that spread across northern MS is now into northern AL and this convection may impede deeper moisture surge into the Middle TN region. However, a well-defined and increasingly buoyant east-west boundary draped across northern MS/AL should provide a focus for potentially tornadic supercells. Shear profiles are becoming quite strong across this region and it appears discrete storms will evolve over the next few hours in response to approaching short-wave trough. Environmental parameters appear supportive of potentially long-track tornadoes and this will be addressed within the next few hours with a tornado watch.

Yes, on occasion pattern recognition and parameters are such that you can identify a potential significant event a week out. It is interesting that the normally conservative SPC would highlight this 7 days out.

DFW area now looking quite ominous for sig svr for Sunday evening with CAPE and helicity quite favorable per 18z GFS this Tuesday if it continues to hold and the first system gets out of the way.

Agree. NAM continues to emphasize a good threat for ne OK and sw MO Monday eve/night with parameters increasing in severity. NAM did better than the more progressive GFS on the Feb. 27/March 1 system so it certainly bears watching as we get closer. Springfield AFD beginning to express concern.

LSR's say trees and power lines down in Whitney area with 4-5 homes damaged, one without a roof.

Good couplet now showing up on NWS velocity radar.

Polygon warnings are not being displayed on NWS radars. HHave had this issue before. Not good when tornadic cells might be headed your way.

As Thundersnow posted the current parameters look very favorable for one of the best set ups we have yet seen this year if they come to fruition. Any analog mentioning 5/3/99 certainly has my attention.

I was thinking of saying this but afraid I'd get slammed. Better you than me. Good luck to all chasers out there in that time period!

Good research, Quincy, on your tornado forecast. I suppose it is always more difficult to forecast trends with tornadoes than what a hurricane season might look like as Dr. Gray at Colorado State and others have done well in advance. My concern for May at least with recent model runs is the apparent lack of a strong jet stream in the CONUS. That, of course, can change.
