nwohweather Posted December 30, 2019 Share Posted December 30, 2019 It is interesting to ponder which event is more likely to happen again, Morch or a tornado outbreak like April 27, 2011. I'd actually go with the tornado outbreak being more likely to repeat. One, we have already seen an outbreak that is relatively comparable or even more impressive in metrics besides the total tornado count (talking about 4/3/74 of course). The other thing is that tornado outbreaks are singular weather events. I'd argue you need even more to go right to get such extreme warm departures in a month.Eh the amount of things that went right for April 27th to occur was insane. The instability and shear overlapped was off the charts, and led to 34 separate long track tornadoes rated EF3 or higher and killed 316 people. Also you can add in the whole outbreak as all 4 days had at least 40 tornadoes. March was an awesome anomaly, but that day was shocking because of its impact Link to comment Share on other sites More sharing options...

March was an awesome anomaly, but that day was shocking because of its impact That's true... as we know, if you change one thing on a severe wx day, it can knock it back from historic to something less than that. That's why the high end days are uncommon and the super high end days are even more rare. Something to consider about Morch. It was about a 10 day period of extreme warmth bookended with lesser positive departures. If that period had fallen from, say, March 27 to April 5, would it have been quite the same? The March departures wouldn't have been as ridiculous. Unlike a tornado outbreak, we are slaves to the calendar when it comes to extreme monthly temp anomalies. 1 1 Link to comment Share on other sites More sharing options...
cyclone77 Posted December 31, 2019 Share Posted December 31, 2019 The extreme warmth in Feb 2017 to me was as impressive, if not more impressive than Morch for this area. At MLI 4 days in a row of 70+, with 5 out of 6 days in a row of 70+. 7 days that month of 69+ degrees. A new all-time record high for the month was set as well as it hit 74 on the 19th. There were 7 new record highs that month. 1 Link to comment Share on other sites More sharing options...

I'm sure some of those days in the late 1800s earlier 1900s had similar tornado numbers but as we know it was way harder to track them all then. Still 4/27 and 74 are in their own class 2 Link to comment Share on other sites More sharing options...

michsnowfreak Posted January 1, 2020 Share Posted January 1, 2020 Not surprisingly, the 2010s ended up as the snowiest decade on record for Detroit!

I'd flip the order on some of them if it were me. Would definitely rank #6 and #7 higher. The November 2013 outbreak would be farther down my list if we're strictly talking about impacts in the LOT cwa. 2 Link to comment Share on other sites More sharing options...

Eh, hard to pick, as they are all high impact, but I personally would have had Morch at least second and bumped the two PVs down one notch. 2 Link to comment Share on other sites More sharing options...
RCNYILWX Posted January 2, 2020 Share Posted January 2, 2020 Eh, hard to pick, as they are all high impact, but I personally would have had Morch at least second and bumped the two PVs down one notch.Agree on Morch. The most anomalous weather event on record should be 1 or 2. I think GHD is fine as #1 ultimately because it's the most intense blizzard for the area in modern history so it really stands out to people. As for #3, I'd still keep that as the entire 2013-14 winter because of its place among the coldest and snowiest on record (coldest Dec-March) period and should be at least #2 for snow if not for the ORD measuring debacle on 1/1/14. Would agree with summer 2012 being higher. GHD II we perhaps could've grouped it in with the extreme cold the rest of February. Also I'd have Rochelle ranked higher than 11/17/13 for tornado events in the CWA. Could make a case that 6/22/15 or 6/5/10 are more deserving to be in top 10 for the CWA, but I understand why it stands out to people because of the time of year and the Washington supercell. Finally, I'd swap out the April 2019 snowstorms for the April 17-18 2013 flooding, which was the worst flooding event of the 2010s for the CWA as a whole. 1 Link to comment Share on other sites More sharing options...
vortex Posted January 3, 2020 Share Posted January 3, 2020 If memory serves me correct, the November 2013 outbreak had 10 tornadoes in the LOT area, with 3 of those being EF2s. Definitely a rare event for November. Link to comment Share on other sites More sharing options...

Geoboy645 Posted January 13, 2020 Share Posted January 13, 2020 MKX finally posted the top weather event of the last year and the last decade. https://www.weather.gov/media/mkx/WCM/2019wisconsinevents.pdf https://www.weather.gov/media/mkx/WCM/2010swisconsinevents.pdf One thing to note is that they are for the entire state, not just the CWA. I agree with the lists for the most part, my only complaint would be the disappointing lack of the Dec,20,2012 blizzard that dumped like 20 inches in parts of the state. Other than that thing, they are pretty good lists. 1 Link to comment Share on other sites More sharing options...
