Weather Talk: Persistent heat F-M has seen this summer likely behind usLast week there was a noticeable change in our weather. After recording only three days in the 70s over the previous 48 days, since last Thursday our high temperatures have been mainly in the 70s. And after today, one (or both) of the next two days may become only the second time with a high in the 60s since June 1.
Is this a permanent change? It seems so. A major storm in the Arctic last week along with some subtle other changes in the flow pattern over the Northern Hemisphere has probably, at least in our region, put an end to the persistent heat of the past two months.
Back in 2006, our last warm summer, after recording 15 days with a high in the 90s (including two above 100) through July, the temperature remained below 90 degrees
for the rest of that summer.
As John Wheeler wrote yesterday in this space, this month has the potential to be the first below-average month in over a year, and it would not surprise me if our autumn started cooler than average as well.
