Through the first 18 days this month, the average daily temperature has been at or above normal every day. Four days featured an average daily temperature at least 10 degrees above normal, and the average daily temperatures for October 4th and 17th were 13 degrees above normal for both days. There were two days on which the daily average was exactly normal for the date (October 9th and October 14th). The monthly average temperature is running 5.4 degrees above normal.
The other story has been the lack of rain. Just four of the last 29 days have featured any measured rain across southwestern Connecticut. Three of those days had three-hundredths of an inch or less. The only day with appreciable rainfall was October 7 when nearly a quarter-inch (0.21") was recorded. The last eight days of September were dry, and there was a nine-day stretch from October 8th through October 16th without any measured rain.
Our weather pattern is about to change, though. A cold front and associated area of low pressure will bring much cooler air and some rain to the region by Wednesday. Daytime high temperatures will fall into the low-to-mid 50s as a storm system moves just offshore. The highs Thursday and Friday will struggle to reach the mid 50s, but it will be blustery under a mix of sunshine and clouds. It will remain in the 50s through the upcoming weekend. I'm sure that will have a big effect on lowering October's average daily temperature.
