Normal also has a win for IAH. For SEA, rather close finish between wxallannj (+2.8) and Roger Smith (+2.5), their math said 2.6 (mine said 2.7) so it's a loss-win outcome on this one. DEN was the same story with the outcome (+3.2) giving RJay (+3.5) a loss and Roger Smith and wxallannj (+3.0) a shared win. NYC, BOS are wins for highest forecasts of hudsonvalley21 (NYC +2.6) and RJay (BOS +3.5) . __________________________________________________ Annual update to follow later today I hope. The scores are close so there won't be major changes.

I have re-ordered the table of forecasts to show the current standings.

Will move that over here towards the end of August, no recent changes other than NYC to 97F. Projections are based on gradually cooling regime in east, fairly static (continued rather warm except in PHX) further west. 22nd _ The anomaly for PHX is estimated from -2.1 after 20 days and a probable -5 or so for 21st. The projections are mostly just extensions of current trends with the larger positive anomalies in the northeast likely to come under some stress from mostly near average temperatures ahead, western locations look likely to maintain trends. The seasonal max contest is still back in the July thread and has seen no further updates since NYC hit 97F earlier this month. Will probably just bring it over to September and start scoring it around first week. 30th _ Anomalies updated, warmer in east. 1st _ Final values have been posted, scoring will be adjusted where necessary by later today.

In the above list, is there any way for you to check the entry that is supposed to end on June 24, 1894 at 3260d because in my data base I do not see any temps above 96 in 1894 and the termination of <99 seems to be July 3, 1898 (100F) which would be 4730 days from the apparently accurate starting date of July 21, 1885 (99F) which generated the 3260d listed. I'm wondering if the program generated an interval from a missing code, otherwise I have faulty data in my data base for 1894.

Two of the four locations edged up today with BWI at 99, IAD at 97. DCA stays at previous 99 and RIC at 98.

Greetings from the source of all heat (sunny 102 F but it's a dry heat) ... anyway, just a reminder to participating NYC forum members that the August temperature forecast contest thread is open. The July scoring has been estimated and almost everybody scored very close to consensus despite a range of forecasts, just all variations cancelling out. This leaves the contest in perhaps the most competitive mode it has seen for many years. Annual update not yet posted but it was close after June so will stay that way, I believe.

I am noticing that 1944 had a similar temperature outcome to what the GFS is advertising, four weeks from July 22 to Aug 18 inclusive looked like this, including a number of daily records in mid-August ... DAILY MAX TEMPS JULY 22 to AUG 18 1944 _ AVERAGE 91.7 F daily max ___ 89 93 93 94 91 93 91 87 91 90 90 81 83 100 101 89 80 85 88 97 102 97 96 95 95 96 95 85 After this temperatures were closer to average, peaked again around Sept 2nd and there was a major hurricane up the east coast in mid-September. 9.40" rain fell Sep 12-14 after a very dry interval mid-July to that event. Other years with significant heat in early to mid August before more recent examples would include 1896, 1916, 1918, 1930, 1949, 1955, the latter had hurricane strikes on the east coast almost concurrent with the heat. I would bet that if this GFS predicted pattern verifies, tropical activity will respond within a few weeks. The timing of this 1944 heat wave was such that it did not dominate either July or August so it is less recalled than some, but in terms of a non-calendar month of heat, it rivals anything else.

And here's part two, the same analysis for daily minimum temps at NYC ... it picks up the tendency for mid-May and early November to run colder than long-term averages, with several records set in those periods, but I don't think that has anything to do with tree canopies in Central Park. Otherwise would say this looks more like you would expect the warmer modern climate to look, certainly December and February have seen disproportionate warmings. The daily mean graph would be a compromise of the two shown. GRAPH: NYC min temp differentials (1991-2020) minus (1931-1990) averages _ shows reduced to near absent relative temperature suppression May to October _ _ (more representative of generally warming climate trend with seasonal variation) _

On that subject of NYC tree canopy temperature reduction, this graph shows the effect quite clearly. The graph is the differential of average daily maximum at NYC (1991-2020) minus (1931-1990). I checked graphs for same differential starting 1996 and 2001, very little difference apparent. Clearly the warming of the climate that is evident November to early April is negated by some factor and I have to suppose it is the tree canopy shading. Will post the same analysis for minimum daily temperatures which shows a somewhat similar trend but without suppressing the summer half year entirely, which is what one might expect, cooler days eventually cancelling out to some extent by the different dynamics of nocturnal temperature patterns. I would regard the minimum annual graph as within the range of seasonal variability in the warming climate although perhaps with a residual effect from the cooler daytime readings. GRAPH: NYC max temp differentials (1991-2020) minus (1931-1990) averages _ shows possible relative temperature suppression May to October _

Thanks for the detailed responses to my questions about NYC, would it perhaps be correct to assume that the temperatures are more affected on the warmest days and those with light winds? I would think stronger winds might mix the air more and reduce the effect of the tree cover?

Since I am doing research involving the NYC data base, I would be interested in thoughts about how long the tree canopy issue has possibly been affecting temperatures and by what amount, also could we say it was an issue only during foliation season? How strong a wind negates it? My belief is that the July 1936 heat wave would have registered something well over 100 F even in today's setting, but that aside, I am looking at comparing data with urban effects considered, and this tree canopy issue is an urban effect in the opposite direction to the urban heat island. My comparisons assumed a gradual rise in the u.h.i. throughout the data set to 1980 and a level signal since 1980 (at some point the urban area gets so large that increases stop happening near its center and are observed further out). The adjustments are more relevant to minimum than maximum temperatures for urban heat islands (typically, if an urban heat island is on the order of 2 F deg, then the average increases will be 0.5 daytime and 3.5 overnight). So I am considering adjusting the urban filter that I applied to include this tree canopy issue, any suggestions? Or is there an argument to be made that larger tree canopies have spread through significant portions of the metropolitan area therefore this is just part of the historical trend and something not to be filtered out, since we don't filter out changes to the agriculture of the great plains etc.

Predict the anomalies (F deg) relative to 1991-2020 for DCA _ NYC _ BOS __ ORD _ ATL _ IAH ___ DEN _ PHX _ SEA deadline for on-time entries 06z Monday August 1st.

As noted in the table of entries, two locations (IAD, RIC) tied their existing seasonal max on Sunday 24th (from early climate reports, will check again later).

Today BWI has moved up to 98F (early climate report, will check again later). The other three locations did not advance today.

Final scoring for July 2022 SEA reported anomaly of +1.9 has to be checked later as two days missing data could alter the value in a later posting of the CF6. Most scores would change by the same amount also, high score(s) for SEA could be reduced slightly depending on what happens. My estimate is that the missing data will, if inserted into the table, change the anomaly to +1.6.

RIC moved up one degree on July 21st to 98 F (table edited). No changes yet to the other three locations. BWI tied their established seasonal max of 96F from May 31st on July 22nd for the second time (also June 17th).

Monday's maximum temperatures in France are running close to GFS forecast projections so this tends to indicate that 40-41 will likely happen in parts of England on Tuesday. The highest value I saw in England on Monday was 38 C at Cambridge, with 37 at a number of locations including around greater London. Ireland also came very close to breaking their all-time record on Monday, which is a mere 33.3 C from June, 1887. An amateur station in Dublin equalled that value but I think the official stations will top out a little lower. There has always been some doubt expressed about the situation of the thermometer (in Kilkenny) for the 1887 record, in 2006 it was 32.8 C for a more reliable record. Here's a link to the maximum temperatures for France from meteociel. You can zoom in on regions using the menu available at the link. These are preliminary values just in since the period for them is 06z to 18z. Note several locations between 42 and 43 C or around 108-109 F. https://www.meteociel.fr/observations-meteo/tmaxi.php?region=

Active shortwave moving inland tonight along the US-Canada border will run into that extreme humidity, some heavy rainfalls likely by Tuesday in that region. It has been quite dry here for the past few weeks, looking forward to some late night thunderstorm activity here, clearing out Monday afternoon. Speaking of the high dew points, I seem to recall some very high dews in July 1995 around Iowa and Illinois. Corn sweat, I believe it is called.

Something comparable might be the extreme cold of winter 1917-18 to the record heat of August 1918. Although that was less sustained than the warmth of Dec 2015. NYC had the example also of the heavy snowfall in late Dec 1947 to the record heat in late August of 1948. Both 1944 and 1948 provide examples of summers when not much significant heat occur before late July and then a lot of heat comes in August. An even faster reversal of large magnitude was 1976-77 when a cold regime that persisted from October 1976 to January 1977 flipped during February to a very warm spring in 1977 (albeit with one brief reversal to anomalous late cold around May 8-9).

With most scores similar in June, there was only one set of changes in ranks; hudsonvalley21 (now 6th) and wxallannj (7th) moved ahead of BKViking (now 8th, although only two points behind 7th place). Consensus moved up closer to second place but did not change its rank, also Normal remained between 10th and 11th, and also there is a prorated score for Stormchaser Chuck (3467), based on 3/2 times actual score, and with that he would be around the same total as our 8th ranked total.
