I think the signal is strong enough at this range to start a thread. However with model variability it's tough to say whether there will be a significant threat the first two of these days, the latter two or all three; or which day(s) if any would feature the greatest threat of a higher-end outbreak and exactly where that would be.

12Z GFS is coming in...system is definitely evolving slower compared to previous runs. What looked like a setup for Monday the 12th two days ago now takes place on Tuesday. Still might be some degree of threat Monday evening, primarily around the Red River region of TX/OK.

Noticing on the GFS an upward trend on the severe weather potential on Wednesday for the same areas impacted with last week's system.

Ah, here's a list of those other dates. All were springtime events in April, apparently.


4/9/15 produced the Rochelle/Fairdale, IL EF4. 4/28/17 didn't produce much but was the day before the two Canton, TX area killer tornadoes (EF3 and EF4). No tornadoes were confirmed on April 30th, 2018. April 26th, 2016 was hyped as a potential big outbreak day and there was widespread severe weather, but issues with storm coverage and veer-back-veer hampered a significant supercell tornado outbreak.

Of course, it's worth reiterating that the way the SPC delineates these areas has changed over time so it's not entirely advisable to take these dates at face value without that in mind, but it being the first such day in December is notable for sure.
