If you have been thinking that the weather this month has been a bit odd you are right! It was pointed out to me by a reader recently just how much things have been out of kilter. If you look at the table below you will see what we mean.

As you can see, we have had eight days thus far in September with temperatures 10 degrees or more above or below normal. Seven of those eight were below normal, six of those were 15 or more degrees cooler than usual. We had one day, the 5th, when we the mercury only climbed to 54 degrees – a whopping 27 degrees below what we would normally expect.
That in and of itself is noteworthy but also notice the temperature swings from day to day. 12 days we have had temperature swings of 10 degrees or more. Four of those days had swings of 20 degrees or more! On the 8th we dropped 27 degrees from the previous day and were 18 degrees below normal. We then followed that up on the 9th by climbing 34 degrees above what we had on the 8th and were 7 degrees above normal.
Now that is some weird weather and if you feel like things have been going up and down – you are right!
Special thanks to David Canfield of Thornton for accumulating the data and bringing this to our attention!
Today at 9:44am marks the Autumn Equinox – the first day of fall. The days are definitely getting shorter and we are seeing less and less daylight. The spring and autumn equinox mark the two days of the year when the center of the Sun will spend a nearly equal amount of time above and below the horizon at every location on Earth and night and day will be of nearly the same length. In short, there is 12 hours between sunrise and sunset. Here along the Front Range we are pleased to see summer-like weather today and for most of the week. 





Thornton is getting a bit of a wet start to the weekend Friday as we have had nearly 1″ of rain fall in the last 12 hours. Those showers will continue off and on throughout the day with a chance for a thunderstorm or two this afternoon.
