TheClimateChanger Posted July 31 Share Posted July 31 1 hour ago, Picard said: I can't imagine lows bottoming in the 30s around here in July as a relatively normal thing. Global warming is definitely in play here, but I wonder if it's also a heat island affect, even though we are further from the city areas, how much of an affect have we seen? Also airborne pollutants trapping heat and not allowing it to radiate off (aside from CO2) And higher dewpoints would likely correlate with less radiational cooling. According to the records of NCEI, lows in the 30s were observed somewhere in the State of New Jersey in the following years. Note, this is not an exhaustive list of ALL 30s. Some of these years had more than one site and/or more than one day in the 30s. This is just the lowest observation each year. The all-time statewide monthly record low is 33F, set at Layton 3 NW on July 3, 1929. The last time a low below 40F was observed in the state during the month of July was July 9, 2000, when Lambertville reported a low of 38F. 1890: 39F 1898: 38F 1899: 38F 1903: 38F 1909: 39F 1912: 36F 1918: 39F 1925: 39F 1927: 36F 1929: 33F 1939: 38F 1943: 39F 1945: 36F 1954: 39F 1957: 38F 1975: 39F 1986: 39F 2000: 38F 1 1 Link to comment Share on other sites More sharing options...

In addition, July 2025 is the second consecutive July with 31 such days, which sets a new record for most consecutive years. The only other years were 1944, 2022 and 2024. 1944 was such a hot summer, pretty amazing for back then. 1944, 1948, 1949, 1953, 1955, 1966 some Hall of Fame summers right there Link to comment Share on other sites More sharing options...

LibertyBell Posted July 31 Share Posted July 31 14 hours ago, dWave said: Thats true. And central AC is much more common down there. Northeast cities were developed before they was AC or even cars. Down there people go from central ac home, to ac in the car, drive to store with ac and ample parking nearby. Meanwhile people in NY tend to experience the weather more directly every day. Subway platforms, while always super hot, felt like a new level today. If records were kept on that, it would of broke it. Somewhere in the 110s wouldn't be surprising at stations like Union Sq or BK Bridge. omg some guy on ABC was using a digital thermometer to measure sidewalk temperatures and it was at 164 degrees, the subway platforms were probably over 200 degrees!!

History) 1981: Springfield, IL reported a total of 10.76 inches of rain during the month, establishing a July record.

During the month of July, Canton reported 12.66 inches of rain and Peoria reported 10.15 inches, both setting a record for the month.

Taken from the Sterling Reporter Volume 10, Issue 3 National Weather Service Baltimore MD/Washington DC Forecast Office Summer 2011 Ref. July 2011 PRESTO Page 1 2017: The famously fiery national park 100 miles to the west set an unpleasant record in July with an average temperature of 107.4 degrees. That ranks as the hottest month ever measured in the Western Hemisphere, according to the National Weather Service. Christopher Burt thinks it might be a world record as well. The weather historian for Weather Underground said he only knows of one monthly average that’s higher — 107.44 degrees recorded in July 2014 at a military base in northern Saudi Arabia — but that measurement has been discredited because it apparently didn’t include overnight temperature readings. “So far nobody’s come up with another figure that’s higher than Death Valley’s,” Burt said. Andy Gorelow, a meteorologist with the National Weather Service in Las Vegas, said unusually hot conditions at night were largely responsible for the new monthly record in Death Valley. The average low at the park’s official weather station in Furnace Creek, California, was 95.1 in July, the warmest of any month on record by more than a full degree. The average high in Death Valley last month was 119.6 degrees. July 7 was the single hottest day, with a high of 127. The temperature never dropped below 89 all month.

DCA recorded 7 days with minimums at or above 80 °F, including a record 4 consecutive days from 21st-25th BWI observed 4 days with highs at or above 100 °F ; 3 such occurrences at DCA and IAD DCA reported 25 days with highs at or above 90 °F; BWI and IAD, 24; setting records at all three locations Ref. Taken from the Sterling Reporter Volume 10, Issue 3 National Weather Service Baltimore MD/Washington DC Forecast Office Summer 2011 Ref. July 2011 PRESTO Page 1 1993: The 30.3 inches of rain that fell during the month at Worth County, Missouri was nearly equal to the amount of rainfall that the area would receive in an entire year. Record precipitation that occurred across a good portion of the mid-Mississippi valley during the summer fell as far east as parts of central Illinois. During the month of July, Canton reported 12.66 inches of rain and Peoria reported 10.15 inches, both setting a record for the month. Springfield's 9.46 inches was good enough for the 2nd wettest July on record. Sioux Falls airport received 7.86 inches. That ranks July 1993 as the third wettest July on record in Sioux Falls. The high total of July 1993 also contributed to the wettest summer (June, July & August) on record in Sioux Falls with 17.39 inches of rain. Crop growth was very slow, with corn and soybeans two weeks to one month behind their normal growth by the end of July in Iowa. Losses in the corn crop amounted to nearly $1.389 billion, losses in soybeans were around $941 million dollars and oat damage was about $26 million dollars. (Ref. Wilson Wx. History) 1994: Philadelphia, PA ended the month with 10.42 inches of rain, breaking the monthly record of 10.30 inches set in July 1919. (Ref. Wilson Wx. History) 1994: Philadelphia, PA ended the month with 10.42 inches of rain, breaking the monthly record of 10.30 inches set in July 1919. (Ref. Wilson Wx. History) Philly had so much rain with a super hot July???? Link to comment Share on other sites More sharing options...

LibertyBell Posted July 31 Share Posted July 31 2 hours ago, bluewave said: This July was a continuation of the rural spots in NJ not dropping below 50°. Prior to the big increase of our summer temperatures in 2010, they would regularly have the monthly low temperature in the 40s. Before 1960 some spots would occasionally drop into the 30s. The lowest July temperatures have risen by around +10 since 1893 at spots like Charlotteburg Reservior, NJ. I dont think you could grow crops here with lows in the 30s, maybe that was a mountaintop thing? Link to comment Share on other sites More sharing options...
LibertyBell Posted July 31 Share Posted July 31 2 hours ago, Picard said: I can't imagine lows bottoming in the 30s around here in July as a relatively normal thing. Global warming is definitely in play here, but I wonder if it's also a heat island affect, even though we are further from the city areas, how much of an affect have we seen? Also airborne pollutants trapping heat and not allowing it to radiate off (aside from CO2) And higher dewpoints would likely correlate with less radiational cooling. if that even happened an argument can be made for global warming being a good thing to keep that kind of cold weather away and increase and lengthen the growing season.

It's not part of our climate to get that cold here in July. Yea that is unusual even in the past. 1 Link to comment Share on other sites More sharing options...

LibertyBell Posted July 31 Share Posted July 31 1 hour ago, Sundog said: At least regarding the airborne pollutants, they were much worse in the past compared to today. NO2 car pollution is much worse today and thats why we have much higher asthma rates now. it got lower during the pandemic. People need to stop driving cars.
