2021 North Atlantic hurricane forecast contest
Roger Smith replied to Roger Smith's topic in Tropical Headquarters
The seasonal count has reached 8/3/1 with Grace briefly a major before (final) landfall and Henri now a minimal 'cane. (note Aug 27, Ida has reached hurricane status and most forecasts assume it will become a major, which would make the count 9/4/2 at that point. The table is edited as of today to reflect that status). (note Aug 29, Julian has come and gone as a tropical storm, table now edited again to reflect that, with the count 10/4/2). (note Aug 30, Kate has formed and seems unlikely to become a hurricane, so I have redone the table yet again for 11/4/2). (note Sep 2, Larry is already a hurricane and guidance seems bullish on its chances to become a major so with the count now 12/5/2 I have rejigged the table below for 12/5/3 (if Larry fails to become a major this will be adjusted later). (note Sep 8, Mindy has arrived in the Gulf of Mexico, expected to remain only a tropical storm ... count once again adjusted). (note Sep 12, Nicholas active in the Gulf, waiting to see if this one becomes a hurricane before editing the table). (note Sep 14, Nicholas did attain hurricane status near landfall, table now updated to reflect new count of 14/6/3). The seasonal predictions you made now require these future outcomes to verify: Required future tropical counts for seasonal predictions to verify _ This table will be updated as new data change the seasonal count _ _ Aug 27 table changed to reflect likely 9/4/2 count within 1-2 days. _ Aug 29 and 30 changes to 11/4/2. _ Sep 2 change to 12/5/3 _ Sep 8 change to 13/5/3 _ Sep 14 count is 14/6/3 FORECASTER _________________ named __ 'canes __ Major _____ additional named, H and M required Macintosh ______________________ 25 __ 14 __ 10 __________ 11 ___ 8 __ 7 Tezeta __________________________ 23 __ 14 ___ 7 ___________ 9 ___ 8 __ 4 Roger Smith _____________________23 __ 13 ___ 7 ___________ 9 ___ 9 __ 4 Southmdwatcher ________________22 __ 11 ___ 6 ___________ 8 ___ 5 __ 3 IntenseWind002 ________________ 22 ___ 9 ___ 4 ___________ 8 ___ 3 __ 1 hudsonvalley21 __________________21 __ 11 ___ 6 ____________7 ___ 5 __ 3 Newman ________________________ 21 __ 10 ___ 5 ___________ 7 ___ 4 __ 2 J_Keith_Lee _____________________ 21 ___ 9 ___ 4 ___________ 7 ___ 3 __ 1 Brian5671 _______________________ 20 __ 12 ___ 2 ___________ 6 ___ 6 __(-1) (6 6 0 best outcome) RJay ____________________________ 20 __ 10 ___ 5 ___________ 6 ___ 4 __ 0 WxWatcher007 __________________20 ___ 9 ___ 4 ___________ 6 ___ 3 __ 1 BKViking ________________________ 20 ___ 9 ___ 4 ___________ 6 ___ 3 __ 1 ___ consensus __________________19.2 _ 9.8 __ 4.7 __________ 5.2_3.8 _1.7 DonSutherland1 _________________ 19 __ 12 ___ 6 ____________ 5 ___ 6 __ 3 (6 6 3 best outcome) Ldub _____________________________ 19 __ 11 ___ 5 _____________5 ___ 5 __ 2 magpiemaniac ___________________ 19 __ 10 ___ 4 ____________ 5 ___ 4 __ 1 NCforecaster89 _________________ 19 ___ 9 ___ 4 _____________5 ___ 3 __ 1 Tom _____________________________ 19 ___ 9 ___ 3 _____________ 5 ___ 3 __ 0 Looking to the skies _____________ 19 ___ 8 ___ 7 _____________ 5 ___ 2 __ 4 (533 best possible) wxdude64 _______________________ 19 ___ 7 ___ 4 _____________ 5 ___ 1 __ 1 TexMexWx _______________________ 18 ___ 9 ___ 4 _____________ 4 ___ 3 __ 1 Cat Lady _________________________ 18 ___ 9 ___ 3 _____________ 4 ___ 3 __ 0 snowlover2 ______________________ 18 ___ 8 ___ 4 _____________ 4 ___ 2 __ 1 Iceresistance ____________________ 18 ___ 7 ___ 3 ______________ 4 ___ 1 __ 0 Rhino16 __________________________ 17 __ 10 ___ 4 _____________ 3 ___ 4 __ 1 (441 best possible) cptcatz ___________________________17 ___ 9 ___ 4 _____________ 3 ___ 3 __ 1 NorthHillsWx ____________________ 17 ___ 9 ___ 3 ______________ 3 ___ 3 __ 0 ____ "Expert consensus" _________ 17 ___ 8 ___ 4 _____________ 3 ___ 2 __ 1 TARCweather ____________________ 17 ___ 8 ___ 3 _____________ 3 ___ 2 __ 0 ____ NOAA median _____________ 16.5 ___ 8 ___ 4 ____________ 2.5 __ 2 __ 1 Yoda _____________________________ 16 ___ 9 ___ 5 _____________ 2 ___ 3 __ 2 (best outcome 3 3 2) LoboLeader1 _____________________ 15 ___ 9 ___ 4 _____________ 1 ___ 3 __ 1 (3 3 1 best outcome) Prospero _________________________ 14 __ 11 ___ 7 ______________0 ___ 5 __ 4 (best possible 4 4 4) ____________________________________________________________________ As of Kate (Aug 30) now three forecasts are impossible to verify but those three can still win the contest by hitting their best possibles. With Larry now a major, a fourth forecast would fall into this category. And with Mindy's arrival three more have drifted into the Cannot Fully Verify Narrows. Most can still win the contest though if they hit their best possibles. Nicholas did not add any new members to the "cannot fully verify" category but drew even with our lowest prediction of number of storms. We are still one short of the lowest number of hurricanes predicted, and had already seen one forecast passed by the number of majors with three others now level at 5. (Aug 22) If we assumed that one third of the season has occurred and two equal thirds lie ahead, the outcome would be 24 9 3 If we assumed that 40% of the season has now occurred but that the remaining 60 per cent would be twice as productive of hurricanes and majors, the outcome would then be 20 9 3 The mean of these two assumptions is 22 9 3. (Aug 27) If we now assume 45% of season has occurred and remaining 55 per cent would be 1.8 times as productive of hurricanes and majors, the new target is then 20 9 4.5 (Sep 2) If Larry became a major and the count was 12 5 3 and we assumed this was the halfway point of the season with an equal second half, the outcome would be 24 10 6. Only one forecast goes higher on named storms, several have higher H and M components. (Sep 8) The forecast models are not too bullish on additional tropical developments in this peak portion of the season so a more subjective outlook now might be around 21 11 5. Just my speculation though. -
Have been following this with interest, my hunch is that it will come in further west than many expect, over western Long Island. Intensity at that point might be marginal cat-1 TS boundary.

NOTES: Very few of the departures (errors) are negative so far (indicated by italic type), those of course can only increase with future changes in seasonal maxima. So in almost all cases these scores can still improve and all the totals could improve. The number in brackets after a few of the total scores are "total negatives" which represent the portion of the score already locked in. Only some of the better scores have this element. The number in brackets then also represents the lowest total score you can now achieve if your positive departures reduce to zero. Second place biodhokie has three of four stations at zero error currently, while leader tplbge has two on the right value with a total departure of 5. Nobody so far has a lower forecast than the actual values at DCA and RIC (for RIC there is still a field-wide three degree shortfall at 96 F, one (biodhokie) has a zero error now for DCA at 97F and there are several at 98F). Took a quick look at today's weather and it looks like none of the above will change today. -

No entry there means same position as last month. Normal passed three forecasters in July, but they remained in same order relative to each other, so their change is shown as zero, Normal is shown up 3.

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.

July 2021 temperature forecast contest
Roger Smith replied to Roger Smith's topic in Weather Forecasting and Discussion
Final scoring for July 2021 Scoring is based on the projected anomalies last calculated in the previous post. PHX and BOS currently scored by minimum progression (max 60) as highest raw scores are 54 and 56. Scoring is probably final, BOS has to be confirmed but is likely to need the minimum progression as shown. Also the quality control step has not been passed at this point (where I double check scoring before adjusting the annual summary).

CONTINUED REPORT ON WEEKLY EXTREMES for WEEKS ENDING IN MARCH Note for weeks ending March 1 to 6, some can start in leap years on Feb 24 to Feb 29, and others in non-leap years start from Feb 23 to Feb 28. The entries for those dates show the most extreme values first, and then the most extreme examples from the other set (as it turns out, a majority of the overall extremes are in leap years). This division is not employed for highest precipitation totals (the extremes can include leap year day, or not). Space is available for secondary extremes but they are only valid within the sub-groups when shown. (ly = leap years, and nly = non leap years ... the overall extremes are underlined for weeks ending Mar 1-6, the order of presentation is leap years, then non leap years.)

I think you'll have a very hot August, when this western heat ridge flattens out a bit more even if only half of its effect reaches the east coast it will be like 1944 with prolonged mid to high 90s. Where I live (about 150 miles north of Spokane WA near the border) we have averaged an incredible 100F for a max over thirty days now. Normal here is about 86F. These super hot temperatures broke records set in mid-July 1941. If you look at what happened after that, the temperature often went above normal in the east and peaked in early October in relative terms, with October's highest temperature at NYC of 94F recorded. So in that case it took about 2.5 months for the heat to translate east. It may be a bit faster this time, if not then September may be the most anomalous month.

Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
I am old enough to remember the 1966 heat wave in the east and this reminds me of that, weeks of mid to high 90s with low humidity levels, a few slightly cooler days in between and no significant rainfall. But in terms of anomaly this is more significant (1966 peaked around 98 to 100 F at various locations), the only thing I can really compare this to would be the 1936 heat wave in some parts of the central U.S., or maybe in terms of anomaly, Dec 2015 in many areas. This is a fairly warm area in an average summer but quite often we don't get this sort of weather until about now, having it from mid-June onward is the really odd part. Late June usually brings one or two cool and wet intervals and July is rarely this dry, August more often has a long dry spell that breaks towards the end of the month.- 323 replies

Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
If today and tomorrow average 37 C here, there will be a 30-day interval from June 17 to July 16 with an average high of 37 C. That is about 7 to 8 deg above normal (C deg = 1.8 F deg). Quite the anomaly, I would imagine the previous maximum anomaly in the summer in this region was half of that. Normally the next 30 days are the hottest portion of the summer so if this goes on another 30 days ... well I hope it doesn't, the results will not be good if it stays this hot and dry (in the 30 days the official rainfall is 0.8 mm which is not enough to drown the spiders building webs in the rain gauge. At my location I estimate 3-5 mm fell (it was just one brief interlude about a week ago that has left no trace).- 323 replies

Tracking The 3”+ Heavy Rainfall Events Since 2010
Roger Smith replied to bluewave's topic in New York City Metro
I will guess August 9-10. -
Record July rainfalls (2021 will pass 1919 in 6th place with any new measurable rainfalls) and what these months had recorded after 13 days in brackets ... 1. 1889 __ 11.89" (2.08") 2. 1975 __ 11.77" (5.08") 3. 1897 ___ 9.56" (3.29") 4. 1928 ___ 8.89" (6.10") 5. 1880 ___ 8.53" (5.22") 6. 1919 ___ 8.50" (0.86") 7. 2021 was 8.49" after 13th 8. 1997 ___ 8.39" (1.70") 9. 1960 ___ 8.29" (1.90") 10. 1988 ___ 8.14" (0.69") ______________________________________________ Looks like 2021 is easily going to get to third place and may be edging into top spots near the end of the month (from the current guidance, would say another inch likely by 25th and then more speculative heavy rainfalls depicted near end of the month). In the weekly summary thread that I started recently, I noted that 2021 had broken weekly rainfall records for several consecutive intervals and the peak amounts (6.58" ending 12th and 13th) represent the second highest totals for any week fully within July with 6.75" from 25th to 31st 1889 the only higher value. Also these were the wettest weeks at NYC since June 7-13 2013 had over seven inches of rain. They were also the wettest weeks at NYC for any week ending June 14 to July 30 (1869 to present).

Heavy rainfalls in the past week have broken a number of the existing weekly totals as noted in the tables. The 6.58" peak amount for weeks ending July 12 and 13 represents the second highest July weekly total, only 25-31 of 1889 surpassed this with 6.75". Going back, the last week (in the calendar year) to exceed 6.58" was June 7-13 (2013, record 7.37") and as it turns out that is also the most recent weekly total higher than these recent peaks.

(turned out by too much as the earlier estimates were closer than the new ones) ... 21st _ Taking the current anomalies forward with little change as the pattern seems fairly static, the western warmth is definitely centered between SEA and DEN and well north of PHX in relative terms, running about +5 here. May post some provisional scores in a while. 27th _ Anomalies updated, PHX dropped quite sharply with two days that had unusual -15 to -20 anomalies due to cloud and thunderstorm activity (highs only in 80s). 31st-1st _ Final anomalies are now posted and BOS is now confirmed after the table had the 31st missing data (for most of Aug 1-2). Scores have not changed there because it was assumed that minimum progression would be needed. Scores are being updated after final anomalies confirmed (this note will be removed when the scoring is all adjusted). -
Historic Pacific Northwest Heatwave of 2021
Roger Smith replied to donsutherland1's topic in Climate Change
Not done with the heat yet, back up to around 38 C in southern BC today. We had a nice break for about 2-3 days, and last night's low of 15 C was welcome. Temperatures inside non-a/c buildings have returned to fairly comfortable values but now we have a few more days of this reduced brand of heat. By the way I had assumed the Warfield climate station was actually in Warfield, but it appears to be about a mile north in a decommissioned industrial facility formerly associated with the Trail smelter, and located about 0.5 miles west of the highway running north out of Trail, in fairly flat and barren land that is largely exposed rock and dirt. So it's not quite as sheltered as I thought it might be if in the village of Warfield which has a lot of trees around. Thus I would modify previous comments about adding a degree to get Trail BC equivalent readings, this site is probably as barren and exposed as any part of Trail even if slightly higher above sea level. I would call them on this site choice except for the fact that much of the urban area of Trail is similarly rocky and barren so perhaps it is a good choice to be representative. Up the hill here there is a lot more shade from trees that survived the smelter years. It did not feel like that shade was doing us a lot of good back in the severe heat wave however. Another interesting observation -- the Columbia River is running quite high and fast, due to snow melt at high elevations up around the Revelstoke region. It had peaked in late May and early June at fairly moderate levels, as it usually does in these flood-controlled times (Trail used to get some fairly severe flooding in the spring runoff), but now it's at least a foot and probably two feet higher. There is a huge infestation of moths in some parts of the Columbia valley, driving at night exposes you to a mass casualty event that needs extensive car cleaning work the next day. It sounds like driving through a hailstorm.- 323 replies

June 7 to 26 (15) __________________________________________________________________ Most of the EDS entries, if not extensions of the first list of absolute dry spells, contain 9-15 day ADS intervals, and a few entries such as the last one add no days at either end of a long ADS, so the EDS is the original ADS. A few EDS have two ADS in their duration, for example 24d EDS in 1874 had 12d and 11d ADS separated by .02" 21 days from Oct 19 to Nov 8 2000 had only .01" (on Oct 29, dividing this into two ten-day dry spells). Two long dry spells in Sep-Oct 1914 were separated by only .28" in two days, and narrowly missed combining for an eligible 49-day EDS. The average year has 6.4 EDS which include 3.6 ADS. The average EDS is 15 days long. Those associated with an ADS are on average about 14 days long. As the amount of precipitation varies from nil to .10" per 20 days, the total precipitation in all these dry spells is probably around 50" (two fairly dry years, but the total length of these dry spells is about 40 years). The average year has 88.7 days within the various dry spells, the range is 18 (2014) to 159 (1909). 1945 and 2014 had the fewest days in qualifying dry years, however, they were not overly wet years, their cycle of wet and dry seemed to be closer to 7-8 days. Considering how much rain fell in 1983, the year managed an almost average output of dry spells, mainly in February and the late autumn. This is a frequency distribution of the months involved in the 97 longest absolute dry spells (15 or more days), frequency assigned by nearest 0.1 portions when the dry spell overlaps two months.

About half of the dry spell frequency is in the period August to October. The following is a graph of the number of days each year (1869-2020) within qualifying dry spells. There are peaks around the 1880s, 1900s, 1960s and (early) 1980s. Peak years from graph: _______ 1885 ____ 1909 ____________ 1965 __ 1980 __ (2010)
