HoarfrostHubb Posted July 4, 2011 Author Share Posted July 4, 2011 Difference between the old site and the airport? 400 feet of elevation. Lol Makes for consistant records Link to comment Share on other sites More sharing options...
OKpowdah Posted July 5, 2011 Share Posted July 5, 2011 9/2/53 they hit 99F. 7/4/1911 they hit 102F. Kinda crazy that that was EXACTLY 100 years ago to today. I think that is the hottest day overall in recorded history for New England. I should probably make a thread about it considering it's the 100th anniv, but I feel too lazy and lousy to look up all of the impressive numbers. I actually was actually just going to post that here ... this is the 100th anniversary of the hottest day on record in NH for sure. Nashua hit 106F (the state record), and Keene recorded their all-time record of 102F. We made it into "Extreme Weather" by Chris Burt ... 12 day heat wave with 5 days above 100F between July 1-12.

snowman21 Posted July 5, 2011 Share Posted July 5, 2011 Does anyone have the # of 90+ days each year for the sites going back to to '71? Here are decade totals... Decade BDL BOS ORH PVD --------------------------- 1951-60 140 133 37 70 1961-70 203 101 31 71 1971-80 212 143 21 97 1981-90 161 125 44 106 1991-00 159 138 26 105 2001-10 191 135 34 117 Interestingly, BDL's May-June-July average high temperature is now about 0.5F cooler over that three month period compared to the old normal values further reflecting the notion of cooler summers. One important thing to keep in mind when looking at these values, and all the new normals for that matter, is the method of computation. The number of 90 degree days is not an arithmetic mean or simple average. In the current normals period, 1981-2010, BDL has seen 511 90+ days for a yearly average of 17 (just about dead on with the old average). In the 1971-2000 period, BDL had 532, so from the last normals period to this one, BDL has lost 21 90+ days. Link to comment Share on other sites More sharing options...

All-time CON record high of 102F as well which has been tied but never officially eclipsed. BOS 104F, ORH 102F, Vernon, VT with the state record of 105F, and North Bridgton, ME 6 days later with a state record 105F. BOS has 4 records during that heat wave with all of them being 100+. ORH's only daily min of 80F happened on 7/4/1911. According to the NH state climatologist on this page: http://www.unh.edu/news/news_releases/2001/august/sk_20010808heatwave.html Keene had a high of 104F in there... "In July 1911, an 11-day extended heat wave set record-high temperatures at many spots across New Hampshire and New England. Keene, for example, recorded daily high temperatures of 91, 95, 104, 103, 101, 88, 91, 99, 102, 99 and 95 degrees." Link to comment Share on other sites More sharing options...

ORH and PVD actually gained 90+ days...how do they drop in the avgs? How do they compute the other values then in this post of yours? Link to comment Share on other sites More sharing options...

ORH and PVD actually gained 90+ days...how do they drop in the avgs? How do they compute the other values then in this post of yours? The big change we are seeing is mostly due to the computation method. 17.7 was the old average for BDL, which looks to me like the simple average was used to compute count normals (other than degree days which have always been treated specially) for the 1971-2000 normals period. For this set new methods were used, and it's not a simple average. Here's a link to the relevant documentation (bottom of page 6 for count normals): http://www1.ncdc.noaa.gov/pub/data/normals/1981-2010/documentation/temperature-methodology.pdf Link to comment Share on other sites More sharing options...

No...hot Saturday in 1975 has that honor in MA. New Bedford and Chester hit 107F.Danbury has the CT record with 106F in July 1995, but the DXR obs from that date only show a peak of 98F (maybe it hit 99F/100F in between obs). http://www.wunderground.com/history/airport/Kdxr/1995/7/15/DailyHistory.html?req_city=NA&req_state=NA&req_statename=NA I assume it was a COOP site that scored the 106F? And if so, I'm not sure how you can get 98F-100F at DXR and 106F at some other location in town. Link to comment Share on other sites More sharing options...

ORH_wxman Posted July 5, 2011 Share Posted July 5, 2011 I wonder who will be the first to start a global cooling rant. Ytterbuim (now OHsnow on Amex) has already started various global warming references in the sporatic threads on '81-'10 averages. Saying how +3 temps "are the new normal".

A-L-E-X Posted July 5, 2011 Share Posted July 5, 2011 Big heat just doesn't happen as much as it used to, it seems. Overnight minimums have warmed significantly, but it's hard to hit the really big numbers for the most part compared to the 1950s and 1930s. Wasn't August 1953 the time ORH hit 100F? You're crazy lol-- have you forgotten last summer already? Big heat doesn't happen as much as it used to? What about 1991, 1993, 1995, 1999 and 2002 lol. And we still have that 11 year cycle for big heat going. Our metro area record temp is actually from 1966, with 107 at LGA and 104 at JFK. Last summer I hit 100+ three out of four days, so not sure what you mean by a lack of big heat lol. I also set my record for 90 and 95 degree days.

I don't know what Nate was smoking tonight, but it must be some awesome stuff get him so "high" that he can't feel the heat up there lol. We get a big heat summer about once every three years or 3 times a decade on average. Link to comment Share on other sites More sharing options...
