Thanks for all data posted about July 1936. There are stories of horrific urban death tolls in Chicago, NYC, and Toronto as well as lots of other places in those pre-A/C days and after a sizzling 105-110 day, no relief even if lows dipped a bit below 80, inside temps were likely well into 90s after a few days of it ... and stories of people sleeping on rooftops and in parks for duration of severe heat. Toronto set high min records only broken once since (78F on several of days of 105F interval). Also to give further idea of upper driving forces in July 1936, Toronto also had its sunniest and driest July on record. It basically did not rain at all and averaged 12 hrs sun per day. Drought must have been extreme in Ontario and upstate NY at least. It was quite warm also in may (a top 20 mean for Toronto and NYC) before a relatively cool June. Upper ridge probably peaking around 603-605 dm over SD-IA early in July, flattened a bit to allow heat to spread east, then retrogressed and a trof deepened over east coast later in July. Some further oscillations in August as heat was unrelenting in central plains states and showed up again briefly in eastern US and s Ontario early August (and again around Sept 18). 1854 was apparently a less extreme copy of 1936. Caswell's Providence RI journal talks about forest fire smoke clouds darkening skies around same time as 97-98 max in Toronto mid-July. As to winter 1936-37, you'll probably find in detail, very cold at times late NOV, milder last part of DEC and all JAN, still quite mild FEB, colder in march -- betting most of 20" snow occurred at bookends of a mild winter. Another summer with extreme heat in northeast US was 1911, any interesting runs of 100+ for you?

I would be interested in seeing data from July 1936 in your region. Toronto and New York City both set their all-time highs in July 1936 (Toronto 105F July 8, 9 and 10; NYC 106 July 9). A lot of other locations in eastern and central U.S. set very high records that month also. When it was reported that DCA matched a string of three hot days set in 1930, I started to wonder why 1936 wasn't in the mix (although NYC only went two days >100). The heat was generally intense from around 7th to mid-month (and also around Aug 3-5). A location in ND (Steele) was 120F and it exceeded 110 in parts of west-central Canada also, although July 1937 produced a hotter reading of 113F in SK and June 30, 2021 broke that national record in BC at 120F in Lytton BC -- it was 45C (113F) at my place so for a day I was living in a location tying our national record -- town of Lytton (pop 1200) was burned to ground by train-track-spark-induced fires on day of record warm max). There has been very little rebuilding yet because of insurance wrangles and archaeology issues (academics wanting to sift soil for cultural relics pre-settlement days). Not that there is any rush to live in this notorious hot spot anyway. On similar topic, a toasty 100F at 1230 local time as we endure day seven of our heat wave. I am by no means in a hot spot here, we live halfway upslope from Columbia River to alpine regions at around 3400' asl, it is probably around 105F in valley now.

WE JEBWALK !!! new contest leader Jebman _ scroll back two posts, scoring table updated. ... only five of 29 forecasters predicted an average 102 or over, current average is 102.5 for four locations. ... only one forecaster carries no expired forecasts (GeorgeBm) ... only four can now win contest (Jebman, George, RogerS, Rhino16) first of all, to overtake Jebman you need unexpired forecasts, of larger value than his differentials ... 1, 1, -1, 0. If your differentials are same at a given station, you have no advantage. A differential of zero at BWI is no advantage now either. This is a list of people with larger differentials than our leader, to use up and gain advantages. (Figure in brackets is your potential advantage, each degree you "receive" gives you a two-point gain vs Jebman, your max potential gain is twice number in brackets.) Same is true for you vs any forecaster in lists below. For example, at IAD, I have a +1 on Rhino16 for a potential gain of 2, but to realize it IAD has to reach 105F or above. For outcomes between current 101F at IAD and eventual 102 to 104, a smaller differential is no advantage over a larger one. You start gaining advantages over field when their forecasts are surpassed. Differentials larger than Jebman at each location DCA _ George 4 (+3) _ this effectively removes DCA from future relevance to contest unless George can hit other targets below since score differential is 26 and DCA only gives George a potential 6 point gain. Also, Jebman moves 2 points further ahead all other forecasters if DCA goes to 105F or above. IAD _ George 9 (+8), RogerS 4 (+3), Rhino16 3 (+2), NorthBaltiZen 2 (+1) __ George can recover up to 16 points vs Jebman, and bring total differential to four (before considering two stations below) if DCA worked out also. BWI _ George 6 (+6), RogerS 2 (+2) RIC _ George 10 (+10), RogerS 6 (+6), Rhino16 3 (+3), RickinBaltimore 2 (+2), yoda, katabatic, midAtlwx 1 (+1). Yoda could finish second to Jebman for a RIC 102F outcome. Last four in RIC list are too far behind Jebman now to utilize small advantages, but would move up by 2 or 4 points vs field if RIC goes to 102 or 103. NBZ is also too far behind to use a 2 point advantage at IAD but would finish second in contest if IAD hits 103F and no other changes took place. Safe zone for Jebman appears to be up to 106 103 106 103 At 106 103 106 103 scores would total Jebman 7 RogerS 9 Rhino16 10 George 21 If any station goes above 106-103-106-103 and rest hit, at that point RogerS could pass Jebman, and has further one degree (2 pt) advantage on Rhino16 at IAD after 104F, and advantages at BWI and RIC also. So Rhino16 can only win at one outcome (I think) and that is 104 104 104 104. (could be one or two successful outcomes nearby also) Going above 106-103-106-103 would mean only RogerS or George could win. Going past 106-105-106-107 is point where RogerS no longer enjoys any part of 12 point advantage as per above, so any addition of total of 6 degrees to that set (as an example 107-107-107-109) would create a tie broken by larger differentials, and any total of 7 or greater would result in a George win. Obviously if George makes targets, nobody will be left alive to discuss it anyway. (jk) So if current heat is ever surpassed in summer 2024 (many hope not) then those are possible contest results.

Large hail signature on that purple cell on radar, look out lower hudson valley. Could also go tornadic.

If you ever wondered, what's it like in Spokane, Boise or Salt Lake City in summer, this is about it, with a bit of added humidity. Around my location, we are into day six of 100+ (we ducked out to coast for days 2-5 for nice 85F relief) and as high as 105F several of recent days, we don't get really low dew points like Arizona, Nevada or southern Utah with the 115/39 sorts of readings, we get 100/60 to 65 fairly often and dew points can be into low 70s if hot air comes in over moist forests as was the case here before about July 5th (fire danger rating was low here two weeks ago, is now extreme as forests have dried out rapidly, but no large fires yet, just spot fires easily put down). If we stay in this heat another week as depicted in our region, we're going to see larger fires in PAC NW region and so you'll be seeing evidence by August or September in terms of smoke layers aloft. So far only large fires seem to be in Utah.

July 2024 temperature forecast contest
Roger Smith replied to Roger Smith's topic in Weather Forecasting and Discussion
Updated highs for 2024 so far ... see June contest thread for forecasts and previous values to date. DCA_104 (7/16) ... NYC_95 ... BOS_98 ... ORD_97 ... ATL_100 ... IAH_ 100 ... DEN_102 (7/12) ... PHX_118 ... SEA _ 98 (9th) I have beat them all except PHX so far (105 locally today July 10). Las Vegas 120 and Death Valley 129, not going to want to beat those. Will update anomalies at mid-month after 16 days as I consider 1-16 first half of a 31-day month. -
Today's record max of 134F at Death Valley is still listed on NWS climate report as a daily record (and all-time), but as mentioned, some doubt was raised about exposure or calibration of 1913 era reports, not saying it was a lot cooler since 131F recently is max more widely accepted. July 10 also one of Toronto's max days from July 1936 (105F on July 8, 9 and 10) in 184 years of records (103F in July 1911 is next warmest) ... NYC max is 106F on July 9, 1936. It is a stifling 101F at my location and 105F down in valley today. A weak cold front made it as far as Cascades but will not have a lot of impact east of Okanagan valley as cool air is quickly modified to near same temps as interior air mass. But a pleasant 75-80F around Vancouver BC today.
-
Las Vegas broke all-time record twice in past few days, 120F and 119F. It was around 105 F locally past two days. Not quite like 2021 but very uncomfortable.
-
Death Valley 129F ... the old record of 134F in July 1913 is no longer regarded as properly exposed but I believe 131F is the accepted top value there. About 95F here today, very low dew points at least.

Looking at various buoy reports and water temps are above 88F even 50-60 miles off coast, and above 92F in shallow waters near coast (Baffin Bay reports 93+). I notice storm surge watch extends to Sabine Pass. If Beryl does continue to track east of guidance it will take longer to reach coastal waters and will have a few extra hours to intensify, thus concern for possible cat-3 outcome if so. I agree it would likely be capped at cat-2 if it does hit west of Galveston as most seem to expect.
-
ICON could be scoring a coup on this, Beryl certainly looks like it is heading for east Texas or even Sabine Pass, and that puts an Audrey evolution in play (Audrey cat-4 landfall June 26-27 1957, catastrophic storm surge and coastal wind damage, and also a long inland path of heavy rainfalls extending into midwest US and lower Great Lakes). Audrey started out from Gulf of Campeche and earlier was only a tropical wave in Caribbean (albeit a week earlier in season). But ominously, storm summary mentions anomalous warmth of Gulf waters in June 1957 at 85F (some readings in path of Beryl are 86-87F). Also Audrey continued to deepen to near landfall and some disputed readings suggest an even stronger storm than is officially catalogued. Some measuring devices were destroyed before peak of storm passed. A large death toll (400-600) ensued mainly from storm surge around Cameron LA. Nobody can be certain of course, but I will punt for possible outcome being a strong cat-3 or weak cat-4 landfall near Galveston or even further east, Tuesday afternoon-evening. The upper level steering environment is almost featureless and if Beryl has another rapid intensification it will cut through a weak upper ridge and join up with trof developing over central plains states.
-
GFS was looking like a possible Texas impact even if landfall occurs in mexico; track turns NNW near coast and only a small jog east in point of recurvature would lead to a central TX coastal landfall. As it stands I would interpret GFS as a direct hit on Brownsville region (forward quadrant still over Gulf) and a significant event for Corpus Christi and San Antonio. Also by GFS 5-7 day standards it is quite a robust looking 'cane after a brief downgrade after Yucatan. It could easily be cat 3-4 in western Gulf. Just speculative at this point and of course GFS far from infallible. Gilbert on a similar track deepened below 900 mbs at one point, IIRC, but was in prime season (mid-Sep).

<<< July daily records for NYC >>> The system used for noting the two day rainfalls is similar to that used previously for two day snowfalls. They end on the date listed, * means that only the record rainfall for the date is involved in the two-day maximum, and ** means that the two-day max comes from the previous date's record rainfall. Temps in brackets with record low mins are non-record maxima associated, to give a more complete picture of type of day setting low minima. Some daily records with multiple ties are shown in full detail by notes below main text.

Roger Smith replied to BxEngine's topic in New York City Metro
Just a reminder to the NYC crew to enter July temperature forecast contest tomorrow, with this weekend's timing I anticipate change of month will not be top of mind ... and contest is getting closer after June's scoring.
