2018 severe wx/chase season discussion

Well barring anything incredible during June, this will go down as my worst chase season since I started in '03. Missed the last couple days out west because of work and health issues. Don't really enjoy chasing the high plains anyway because of altitude, so I'm not terribly upset. Anyways....been watching Saturday in Northern MO. Friday is on my radar as well, but its been trending downward on the GFS and especially now the NAM. Maybe an 11th hour savior like Pilger/Coleridge or even the June 28th outbreak last year in Liowa? You won't catch me complaining.

On another note, I don't think I've ever seen a year where everything (not saying much here lol) has been clustered over Colorado and Wyoming (other areas of high plains). Kind of annoying for anyone that lives like 13+ hours away, but I guess that's just how it goes.
 
I think the blocky pattern kind of favored CO/WY and perhaps MT starting Thursday. West troughs make headway to the Rockies; then, eject north. UULs and mid-level lows in the Tennessee Valley/Mid-South created a quasi-rex block. Call it billiard ball meteorology.

I still have not traveled to the Plains. Talked myself out of this week due to moisture concerns, but late May climo finally won out. Happy for chasers who saw stuff Sun-Tue or any other time. Rest of this week is in Target Area...

Next week most models have moderate flow across the northern tier of states. Could bring more action to the Northern High Plains and perhaps get the Upper Midwest involved. June the Upper Midwest starts seeing more action per climo. Back East, occasionally NWP shows some Mid-Atlantic signals, but it is virtually unchasable.
 
The projected evolution of this incoming trough for tomorrow and the weekend is just baffling to me. For example, on this morning's 12Z NAM it looks like a relatively decent (especially by 2018 standards) negatively tilted trough at 00z Saturday (for Friday afternoon/evening). However at 00z Sunday, the warm sector has zipped up far to the southeast (after the triple point was near the Canadian border for Friday) with almost no 500mb SW flow east of the trough axis. It's all lagging way off to the northwest, behind the warm sector.

Just annoyed at yet another year of after picking the deadest week possible in late May for my "chase" vacation, the atmosphere finds new and different ways to shut MBY (S. WI, N. IL, E.IA) out of events so I can't even get in any decent local/regional chases.
 
So disheartening on the GFS to watch that powerful southwesterly jet stream roll into the PAC NW then just get shoved back into Canada by the giant ridge. Looks like there will be no June redemption for 2018.

The Euro is more or less on the same page. We could see more severe thunderstorm activity from Idaho(!) into Montana/Wyoming and the Dakotas, otherwise ridging dominates. Into week two, the Euro ensembles show, yet again, a return to troughing over the Great Lakes/Northeast. While some severe would be favored in such a pattern from the Upper Midwest into the Great Lakes, it looks like more of an MCS/derecho pattern than anything else.
 
The 2018 season is officially over for me. I will post a summary here, which I believe is more appropriate than to put it in the Reports section, although I may post more details on individual days there.

First, I will say that while the season was objectively speaking a poor performer, I was pleasantly surprised to have a decent week that featured 5 chase days (5/27, 5/28, 5/29, 5/30, 6/1), 4 of which had decent potential (5/30 being the one that did not), and could have had one additional day (6/3) if we had chosen to take a chance with the terrain and sparse road network of central NM. This shows that even in the worst seasons there can be a few good days and it’s worth coming out, but this would not have been possible without the ability and willingness to time the trip with a somewhat more favorable-looking short-term pattern. Nonetheless, clearly not a good year and definitely one of the five or six worst since I started chasing in 1996. The other bad years, in no particular order, were 2000, 2006, 2009, 2017, and maybe 2002. Actually my first year, 1996, was not good either, but it was a relatively late trip - first two weeks of June - and I have no recollection of what the rest of that season was like. Our trip this year was definitely better than 2000, 2006 and 2017.

I’m talking strictly in terms of opportunities though, because we did not fare too well in our chases. Here’s a quick rundown:

5/27 - did not target southeastern WY. Enough said.

5/28 - focused on the KS portion of the OFB and missed the landspouts in northeast CO

5/29 - enjoyable chase picking up the OK supercell from its birth near Laverne/Buffalo but missed the tornado up in KS. It seems many chasers did the same, judging from the hordes around the OK storm

5/30 - half-hearted chase into southeast CO, did not want to venture too far knowing we had to head north the next day; pretty uneventful day for most I believe

6/1 - underperforming storms in Nebraska, wish we hadn’t been too lazy to drive up to North Dakota... Nice evening though, found a great new brewpub in the middle of nowhere in Broken Bow, like a dream come true to have a beer while watching a spectacular mammatus display and lightning show as the line of storms finally got cranking and shifted off to the east. A nice example of the road trip adventure of chasing and finding things to appreciate in a bad year.

6/3 - decided not to chase NM due to terrain/roads and then regretted it most of the evening. Don’t think we missed anything that great and don’t know if we could have gotten any good vantage points anyway, but probably should have gone for broke on the last day.

I could stay out part of this week and fly home Thursday, but nothing looks worthwhile and with family and professional responsibilities beckoning back home, it just doesn’t seem appropriate or worthwhile to continue jerking around out here. I fly back to Philadelphia from Denver in a few hours from now.
 
In a typical season I'm out a couple times a week locally shooting lightning. This year I've gotten the camera out once.

Been on only two daytime chases.

Waiting for monsoon. Maybe? Maybe.
 
Lets just start a 2019 chase season discussion topic and forget this year even happened. :mad:

Yep. Went straight from the cold eastern trough from hell to the death ridge from hell with no time for a real storm season in between, just the half-@$$ed early May sequence that produced Tescott-Culver.

Probably the only year as bad or worse since I started religiously following severe weather activity is 2009. 2005-06 at least had the late and early season flurries of activity, respectively, 2012 had March 2nd and April 14th and 2013 had the back half of May (although I remember those latter two as bad years because I didn't have the resources to chase the Plains yet and there was little activity locally).
 
Trescott could have been the beginning of a nice sequence for a few days; but, that awful mid-level trough invaded the Mid-South and cut off the Plains moisture. Similar to last year, we did get a mid-May trough. Also similar, only one day panned out.

Oh and like last year, I did not take a Plains trip. Thursday looks good; but the more I dissect Wed & Fri, the less I can justify biting for just Thursday. Who knows? Al 3 days may produce off terrain features.

Awaiting the European weeklies tonight. CFS charts and Dashboard offer hope next week. However if the ECMWF does not get on board, I will assume no Plains chase this year. Oh well!
 
Interesting how different chasers view different seasons based on their own experiences, memories (and memory retention), and timing of their chase vacations. The seasons that almost everyone agrees were bad I guess were definitely the very worst. I thought 2006 fell into that category but I had no recollection of the early and late season activity Andy mentions. 2005 I seem to remember was pretty good, wasn’t the Hill City / Zurich KS tornado that year? Even one good tornado day can make a season - but having said that, even with Campo in 2010 I don’t remember it being a great season, that tornado was 5/31/10 but I remember the whole first week of June (second week of my chase vacation) not being very good at all. For 2012 I have a good memory of Lacrosse - there probably wasn’t much else, but for whatever reason I don’t have a specific memory of an inactive week like I do from 2010. Even 2011, there was an outbreak day where we got the Canton Lake tornado so I see that as a “good” year and don’t remember anyone ever suggesting it was bad, but I don’t remember seeing much other than Canton Lake. Despite everyone’s overall opinion of 2013, I continue to believe that the last two weeks of May had to be among the best two-week periods ever in terms of the number of opportunities and high-profile events (Rozel, Shawnee’s, Moore, El Reno and other decent days as well). Meanwhile, I agree 2009 was bad and I remember delaying my trip all the way until on or around June 1, but I remember feeling somewhat satisfied with a good solid number of chase days during the short 9 or 10 day period that I finally did take my chase vacation.

It is also important to be objective about our own success/failure. My memory of 2013 as a great year is despite an epic failure to see any of the events listed. I will remember 2018 as a bad year but also a year that confirms you just need to get out here, as one could have seen tornados on three straight days - even though I missed them all. Definitely better than 2017, when we had just two poor chase days, followed by four days of nothing and then just going home because of the following week’s forecast. Even 2016, after Dodge City (got it) and Chapman (missed it), things shut down. In fact, I was prepared to come back out and use my “second week” some other time, but no other week ever looked good again. I guess the point (other than to commiserate and reminisce in general) is that so much is subjective perspective for an individual chaser, regardless of what the data shows.

I can tell you it was a sad walk through the DEN terminal today, remembering how I walked the same path in the opposite direction when I landed last Sunday, full of hope despite the general pattern. It’s sad when any vacation ends, but chase vacations are different because you can return completely unfulfilled and unsatisfied.
 
I'd have to go back and look in my chase records, but I recall one or two years when smoke from massive wild fires in Mexico, mixed with high humidity, produced zero visibility beyond 10 miles in most regions of the Plains from south to north. I believe those years were before mobile radar, or at least one of them. It totally destroyed most of the season, or at least made chasing very difficult.
 
I always like to stay optimistic, but that ridge currently in place has all the looks of our annual spring season-ender. When robust troughs repeatedly come in and can't get through it, that's one of the big signs it's here - and here to stay. Even though there are some bigger 70s swaths showing up on the moisture progs, we never did get one of those nice deep Gulf moisture fetches that can adequately supply your typical central-northern Plains events. I won't rule anything good out completely, but my bet is that any Dakotas/Canada system over the next couple of weeks will underperform.

That being said, the Midwest opportunities will still be there, those are what I'm unofficially turning my attention to.

I believe the year you are referring to was 2003.
