Got a bit chilly last night,had to turn some fans off

8 AM temperature Nov 4 OK I was way off on that one.  I expected night time temperatures to drop into the teens about mid November, as last year.  Cooler temperatures arrived earlier than I have noted in the past five years of weather tracking. Temperatures began falling yesterday.  It was not very noticeable until early afternoon. Temperatures were cloaked by the humidity.  The coldest time of the  day is generally between 4 and 6 am.  I am certain the temperature was 19 earlier this morning  OH I should mention, some forecasters are predicting coolest cool season in years, decades maybe. They did forecast a few days ago that temperatures would drop, but did not specify where I thought  Somewhere, not in Sakon Nakhon
