September 1st is the start of meteorological autumn, but Mother Nature never has been one for calendars or man-made borderlines.
Yesterday, the high temperature at RDU was 93 degrees. At the National Weather Service office on Centennial Campus in Raleigh, they recorded a high of 95 degrees, which was hot, but not record-breaking.
Today's expected high temperature should be in the mid-90s with a heat index as high as 100 degrees. Luckily, today should be the hottest day of the week. Still, the temperatures are expected to remain well above our normal highs of the mid-80s through Saturday, if not longer.
What is the latest date the Triangle has seen a high over 100 degrees? September 10, 2007, had a record high temperature of 101 degrees. As for temperatures above 90 degrees, October 10, 1939, is the latest on record with 91 degrees. So, despite yesterday being the first day of fall as far as meteorologists and climatologists are concerned, it would not be unheard of to have summer-like temperatures last into October.
