"The past few days have delivered the lowest-maximum temperature in more than a century to Concord, New Hampshire, according to National Weather Service (NWS) data.
On Saturday, New Hampshire’s capital city of Concord logged a high temperature of just 59F (15C) — a reading that busted the previous coldest-high temperature of 61F set way back in 1914.
The year 1914 fell during the Centennial Minimum (and also the Solar Minimum of cycle 14), which is the last time the sun was experiencing a spell of reduced output comparable to what we’re seeing today:
Concord’s record cold is confirmed by NWS meteorologist Michael Clair, who is based in Gray, Maine.
Clair notes that the historic chill came hot on the heels of the heat wave and near record-high temperature of 96F (35.5C) last Thursday.
Thursday’s high didn’t quite usurp the all-time benchmark, which still still stands as the 97F (36.1C) registered back in 1964, according to NWS records.
The year 1964 also fell during a Solar Minimum (of cycle 19), and so again demonstrates the link between low solar activity and meridional jet stream flows
— a combo that routinely throws weather patterns ‘out of whack’ ...
... back in 1911, the New Hampshire/Maine region was suffering one of its “worst weather crisis in its history” (note: it was called ‘weather’ back then, not ‘climate’) as a July heat wave cooked the entire Eastern seaboard, with factories shutting down and people collapsing in the streets.
Note also that the year 1911 fell smack-bang in the middle of the Centennial Minimum and after the historically weak solar cycle of 14 (again, the previous cycle comparable to the cycle we’ve just witnessed, SC24).
Everybody “suffered as never before,” reported the Lewiston Evening Journal at the time.
Thermometers touched 110F (43.3F) on July 10, 1911, and many of them broke when they got too hot, reports unionleader.com.
“Never was there a worse night in the history of Lewiston and Auburn than the one that began after an exhausting, humid day in July 10,” added the Lewiston Evening Journal, “hitting a crazy overnight low of 75F (24F).”
That “worse day” sill hasn’t been surpassed, even after 40+ years of ‘catastrophic global heating’."
