Down 32 degrees in 43 hours

After watching New England weather closely for a year, I've seen some wild temperature swings. But, one thing I rarely see is wild swings in the dew point. The dew point tends to be quite a bit more steady than temperature. But, with the latest storm that rolled through, I saw an amazingly large change in dew point---30 degrees in less than 48 hours. The remains of Tropical Storm Nicole made its way to the Boston area Thursday, September 30th. This pushed the dew point up to 71.9F degrees at 12:40pm on Friday, October 1st. I had to turn the air conditioning back on even though we had seen a low temperature of 42 just a week prior! The storm dumped .64 inches of rain then departed out to sea, taking all the humidity with it! The dew point fell quickly, bottoming out at 39.6F at 7:30am on Sunday, October 3rd. So, the dew point dropped 32.3F degrees in just under 43 hours! We had to turn the heat on this morning after having the A/C on just two days ago. Phew!
