This will be the final monthly contest for 2021 in what has proven to be a fairly close competition. I have added on the winter snowfall contest with the same stations in play as for the past few winters. Note carefully the substitutions for low-snow locations in the temperature contests. For the temperature forecasts, anomalies relative to 1991-2020 normals (F deg) for these nine locations: DCA _ NYC _ BOS __ ORD _ ATL _ IAH ___ DEN _ PHX _ SEA and for the snowfall contest, six of those plus three more northern locations ... DCA _ NYC _ BOS __ ORD _ DTW _ BUF ___ DEN _ SEA _ BTV deadlines for both contests 06z Dec 1st, some leeway will be allowed for the snowfall contest. Good luck !!

Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
Further to the above, the mudslides that hit BC Highway 99 east of Pemberton have probably caused several casualties, eyewitnesses state that a second mudslide hit a group of people who were stopped by a previous slide, and swept away, fate unknown at this point as search and rescue have to go through the first slide to get to the second one (from either end of the route as there are multiple slides). Since I posted earlier, the storm has moved on with one last blast of strong winds doing considerable damage around Kelowna, BC. My location had some strong gusts around 0100h today but no local damage other than tarps not well enough secured being blown across a residential street.- 323 replies

Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
So to follow up on this second weather disaster, things are actually quite serious in terms of property damage, so far a rather slight casualty toll. As some readers won't be very familiar with BC geography, I will describe what I'm hearing in terms of driving east out of Vancouver which got a lot of rain and some localized but not too severe flooding. As you get further into the Fraser valley it gets worse. The cities of Abbotsford and Chilliwack have scattered neighborhood evacuations due to stream overflows combined with mudslides. The main highway to the interior of BC east of Chilliwack BC is closed at Bridal Falls and if you live in Hope BC you can only go a few miles in any direction as all highways from there are blocked by floods and or mudslides somewhere in the Cascades. Along the north shore of the Fraser, another highway is also blocked in two places. About 30 vehicles were trapped between those two slides last night and the people were rescued by helicopter today. Nobody is known to have been swept away in either slide but from the news footage that looks like a week to two week clean up. Then going further into the mountains from Hope, the main route to Kamloops and Calgary is washed out by severe flooding, and the city of Merritt in the plateau area further northeast is fully evacuated with 3-5 feet of water in most of the town and no drinking water or sewage treatment. That's a community of about 8,000 people. Then on the southern route that goes east from Hope, that highway also washed out in places, and the town of Princeton has seen considerable flooding also from rivers running east from the Cascades. Reports of 8 to 12 inches of rain in total. The rain has moved on and a squall line is approaching my location (which is 250 miles east of Princeton). We have had a very mild day with southerly winds but from the radar it looks like a squall line approaching. Southern Alberta had the chinook today as well as Montana, temps into the low 60s and wind gusts to 70 mph. Looks like even stronger winds could develop as this low is quite intense now, heading inland across the Rockies. So a very expensive storm but lacking any significant death toll to match the summer heat wave casualties which are estimated to be in the 500-800 range in BC.- 323 replies

Some Thoughts on the Winter 2021-22 Outlook
Roger Smith replied to OHweather's topic in Weather Forecasting and Discussion
I live near the US-Canada border in south central BC about 150 miles north of Spokane and 50 miles west of the northwest tip of Idaho. We are at about 4000' elevation on the west side of the Columbia River in a ski resort town (Rossland BC). It is also 25 miles due south of YCG in terms of weather stations (and quite a bit higher, we have mountains to our northwest reaching 8000' in the south Monashee range which is just big hills compared to either the Cascades further west or the Selkirks and Rockies further east. Those all go well above 12,000' in places. This is a heavy snowfall zone most winters and we can have 3 to 6 feet of snow on the ground at times in Dec and Jan. But spring comes fairly early despite all that. And we hit 112 F here in the heat dome last June. Have lived in BC since 1995, mostly down at the coast in Vancouver area. Before that, lived in Ontario in various locations, most recently near Peterborough northeast of Toronto. So as an older person I have memories going back about as far as 1960 for Ontario winters. Despite all the talk about warming, some of those winters were quite tame as well. Others not so much. -
Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
Now looking like B.C. may have a second major weather disaster for the year, there has been widespread flooding and landslides in the past two days from the strong "atmospheric river" event still ongoing, will post more info when news reports are more informative, last night it was mostly "we are hearing ... but cannot get into" sorts of stories but basically it seems that multiple small tributaries of the Fraser River have overflowed in various residential areas of the Fraser valley (50 to 100 miles east of Vancouver is where the worst damage is likely to be located). Three major highways are closed by flood and mudslide damage, cutting off all access from the coast to the BC interior by the usual routes, road access through Whistler and Pemberton is still open at last reports. Or you could go through WA state as they are not getting that much rain south of about Bellingham. The border was just opened up the other day for Canadians who wish to drive into the U.S. on non-essential trips, but other than snowbirds heading south to their winter homes or campsites, very few are going yet as there are expensive testing protocols when (or if) we return. And watching the golf from Phoenix yesterday then looking out at the mess of slush on our street, I was thinking, why the heck would I return?- 323 replies

Some Thoughts on the Winter 2021-22 Outlook
Roger Smith replied to OHweather's topic in Weather Forecasting and Discussion
I posted earlier that I was expecting a reasonably active winter pattern to develop for the central and eastern US, probably a lot of variability but some hope for wintry scenarios at times. Now I'm noticing a distinct resemblance to late autumn of 1981 with these very severe rainstorms we are getting here (in BC) -- Nov 1981 had similar episodes. The late autumn of 2006 was very stormy also but not this wet. So if that gives a nod to 1981-82 as one possible analogue then of course it was in that second tier of good winters below the really outstanding ones; not much happened (in the east) during December as I recall since I was living there in 1981, and there was a large-scale pattern change in the new year, severe cold at times, and one or two coastal storms about which I remember very little, the snow largely missed Ontario where I was situated and while it was very cold at times, the ground was almost bare outside the snow belt. Feb 1982 was dry and cold inland too. There was a resumption of severe winter weather in April for about a week. About the severe rainfall event, it has washed out two or three major highways and caused urban mudslides. In Nov 1981 there was a bad situation north of Vancouver on the highway to Whistler where a mountain creek swept away a bridge and several vehicles, since then they redesigned all the bridges so that debris can't block the creeks as happened then. A similar disaster in Oct 2003 a bit further north but that was a heavy rain from a Pacific typhoon remnant and I don't remember the rest of the autumn being very stormy. There is some very mild air getting in from the Pacific now and up to quite a high elevation melting a snowpack that just formed, so the flooding with the 6-8" rainfalls is intensified. Luckily there was a fairly good forecast of this and the highways people closed one highway just before it got over-run by a huge flood -- this is ongoing and it may end up totally obliterating the highway for about a half mile, as a river is now running down one side of the divided highway and the barrier is collecting all the debris as it washes over top of the median. Haven't seen a start of a winter season much like this in the 27 years I have lived out west, so the pattern is a bit extreme at the moment. -
November 2021 temperature forecast contest
Roger Smith replied to Roger Smith's topic in Weather Forecasting and Discussion
You never know with Denver, they can run +4 for three weeks and then lose it all in two or three -25 anomaly days but PHX seems to run either blandly 2-4 above average or quite chilly the odd month, so far this has not been the odd month. This is the hardest I have ever hugged consensus in about ten years of these contests. It might prove to be a good idea. -

Problem with varying width of forum on screen
Roger Smith replied to Roger Smith's topic in Forum Information & Help
Okay, for whatever reason the width on screen has more or less returned to normal and the tables are now much more legible as they generally don't wrap now. If somebody did something, thanks. Will continue to monitor in case it goes back to the narrower screen. -
This would get the name Adria if they do name it, as you know, Greek letters were shown the door and now we have a supplementary list which has these names -- Adria, Braylen, Caridad, Deshawn, Emery and Foster. As it might be a hurricane right away, the count could be 22/8/4 if there is in fact a name given. (current count being 21/7/4).

2021 North Atlantic hurricane forecast contest
Roger Smith replied to Roger Smith's topic in Tropical Headquarters
Well the convention in other contests that I enter (and one that has been going for many years and that is not scored by me in one case) is to treat all similar forecasts as separate entities and in all probability BKViking (who is a regular in the temperature forecast contest) never noticed that he was making the same forecast as wxwatcher007, or else did notice and agreed that was the call to make. The convention in those other contests is to rank the identical forecasts from earliest to latest entry which I did not do here (yet). I see your point but just to let you know that this scoring convention is fairly well established in weather contests and not something I introduced here for the first time. (later edit _ I went and had a look, realized that in fact it would make no difference to anything if I went with this suggestion, so I have edited in the changed ranks and also removed some gaps in the table that served no actual purpose. ... so now it is ranked the way NC89 suggests.) Also by the way there was no actual reason for that gap in the scoring table, it wasn't on my screen but what I see and what gets posted sometimes not the same thing. I can probably just edit the table to show the ranks the way you suggest with an asterisk noting that two forecasts are at the same rank. But be prepared if you enter other contests in other places, that's how they normally handle identical forecasts. I suppose the cases I had in mind would deal with duplicate values on a regular basis, for example, one temperature value and fifty to a hundred entrants, you will always have clusters of multiple entrants at one value. And in my experience you finish ranked behind all of them if their errors are smaller. But what can you do when there are more entrants than plausible entry points? With this contest the complexity is greater so that 30 people could all choose unique forecasts. On the other hand, I don't think there is anything basically wrong with placing an identical forecast, if this is what you think is going to happen, it's your best effort and the fact that somebody else thought the same thing might not be any contributing factor. Some people in past years have repeated the NHC or CSU numbers, would we penalize that or simply view it as prudent forecasting, after all, whose numbers should be best, me at my desk here in the middle of nowhere, or some established expert(s) being paid millions to do this sort of work? (so why do some of us, well let's not go there) .... -
Later guesses for the other three won't be eliminated until at least one other station goes in this window of opportunity, as most of those who scored well on IAD have similar dates for BWI and some also for RIC. My thought that it would resemble 1963 has suffered from a fast forward, we had the warm dry three weeks and the warm wet week all compressed into one month now Nov 2021 looking a bit too much like some colder analogues, wouldn't go with my present guesses now but could get lucky I suppose. There's a mountain of hot air from central DC, somebody should look into the reasons for that.

Problem with varying width of forum on screen
Roger Smith posted a topic in Forum Information & Help
Could anyone in the know help me out with this problem? I posted a thread in the climate change section with extensive data tables (Toronto and NYC historical weather). The thread is basically a copy of something I posted on the UK weather forum "net-weather" which has a very similar graphic design to this forum. And my thread over there is fixed in width so that the tables do not wrap. Here, after a while the on-screen appearance of the thread got quite narrow compared to other threads that I either started or that I visit on American Weather Forum. It is basically about half as wide as it needs to be, so all the tables are now wrapped in appearance and that makes them almost unreadable or unusable. There is a link posted to net-weather so any determined reader could go there and see the tables in their proper format. Anyway, if there's something I can do (or undo) that would solve this problem, I would like to hear about that, or, if a moderator could get into the background of the program somewhere and force a width onto the thread, either of those might solve the problem. Alternatively if readers go there and find that they don't see the same problem, then it resolves the situation since I don't need to see the tables in their correct form to edit them. (I regularly add new information as it comes in). Thanks in advance. -
Thanks for adding those snowfall totals. Some time this winter I will add in maximum weekly snowfalls for each date. Meanwhile, three new weekly rainfall totals have been set in 2021, weeks ending Oct 30, Oct 31 and Nov 1 all have slightly higher totals now than before. The records broken were from 1917 (30th) and 1943 (31st, 1st). The new records are 4.70" 4.71" and 4.48" ... there won't be any further records until the next time heavy rain falls, as today (Nov 2) we lose the 3.30" from Oct 26 which fell just short of being the seventh daily record broken in 2021 (1943 held on at 3.40").

The backup of posts is no longer needed and has been deleted now that the table of entries is complete. Good luck everyone and welcome to Stormchaser Chuck. I have posted scoring for October including an annual update; this will be adjusted tomorrow but the anomalies cannot change very much as they are based on all info now. See also notes at the bottom of the annual update about your status in the best forecast and extreme forecast tables. If S.C. wins any of those awards, it will be noted but then a second award will take place within the regular group of forecasters (which includes DZ who has four contests now -- if you're wondering why you can't see DZ in the thread, he submits by e-mail as this is his only participation in Am Wx at present.) Which reminds me, check my e-mail. -

So far this year, 69 locations out of 90 have qualified, 4 in Jan, 5 in Feb, 7 in March, 6 in April, 8 in May, June and July, 7 in August, and 8 in September and October. Of those, 38 were awarded to warmest forecasts, 31 to coldest. A loss in the standings represents a case where second most extreme forecast had the high score and the win for that month. Normal can only win along with a forecaster. There have been eight shared wins (one by four and one by three) accounting for the excess of total wins (excl Normal).

2021 North Atlantic hurricane forecast contest
Roger Smith replied to Roger Smith's topic in Tropical Headquarters
Now that the New England storm has become STS Wanda, we are at 21/7/4. Later today I will edit changes into previous posts about scoring, removing now-excluded possible outcomes. Wanda could become a hurricane (not the current NHC prediction) but seems unlikely to be a major hurricane so that 21/7/4 and 21/8/4 scoring will remain as well as options for 22/7/4, 22/8/4 and 22/8/5 and 22/9/4, 22/9/5 -- previous scoring tables are now updated. -
Mid-Atlantic winter 2021-22 snowfall contest
Roger Smith replied to PrinceFrederickWx's topic in Mid Atlantic
Imagine the fun you could have in these contests if you could control the weather or travel in time to find out the results. Like olafminesaw. -
The biggest snowstorm in recent years happened after the warmest December, so the argument that the current warming climate will cap this potential is inherently weak. The distribution of extreme precip events tends to swing wider from the median than temperatures which rarely do what I experienced here this summer, a 5 degree increase on long-term extremes. It is not so surprising when a new rainfall record for a given location is twice the value of the old one it replaces. Subjectively, I don't imagine that snowstorms from 2010 and 2016 will be beaten in this coming decade but would you bet against them being edged out within a century? So I think maybe the answer to this question is around 40" and possibly more. A very high snowfall total for one storm in your region would definitely require a stalled low tucked into the coast in a suitably cold regime. This rarely happens but there is no theoretical reason why it couldn't happen. If there was a natural variability change to colder climates, which probably will happen at some point in the next century or two, then the odds of such an event would improve. So I would hazard the guess that if anyone retrieves this thread in the year 2100 and checks it out, they will be talking about the 35 to 40 inch snowstorm of 2063 or some such thing, and wondering did we hoary ancients foresee such a thing? I just did.

Mid-Atlantic winter 2021-22 snowfall contest

I would not give up hope for this winter. For one thing, warm Octobers have often been followed by productive winters in the northeast so that can't hurt the chances for the Mid-Atlantic. Don't know how your region did with the epic Dec 26th 1947 (NYC region) storm but that followed the warmest October on record. Octobers of 1963 and 1971 were high on the list also, and had at least reasonable winters with spells of mild and cold and one decent snowfall event (again this is for the northeast, I don't have your historical records at hand). And on the other hand cold Octobers have often been followed by unproductive winters. This of course is only analogue forecasting without reference to teleconnections or other more sophisticated indices. Some of the years that have looked rather similar to 2021 (albeit in cooler climate decades) include 1898 which had a famously cold and snowy winter following on. 1916 had a cold winter (1916-17), not sure as to snowfall with that. Also would point out that recent storms are showing tendencies to do things that we can say would be good for snow potential if they did similar things in the heart of the winter season. Overall I am going to make a fairly moderate prediction (in the snowfall contest) but I do think there is potential for this to turn out better than some are fearing. Totals around 15-25 inches may be attainable. It won't likely be a top ten sort of winter but there may be one memorable cold spell and snowstorm associated.

Potential Major Noreaster 10-26 through 10-27
Roger Smith replied to ineedsnow's topic in New England
The NHC continue to suggest that this storm now northeast of Bermuda heading southeast may become Subtropical Storm Wanda in a few days. So for a name it could be Wanda in the Womb, or maybe Backwards Bob. Perhaps re-analysis will establish that it was already TS Wanda in its earlier rampage, and as somebody mentioned, it was very close to cat-1 hurricane intensity over the Cape. The perfect storm of 1991 is now referenced as an "un-named hurricane."
