Our last 80?

Our stretch of rather spectacular fall weather continued on Tuesday with high temperatures well into the 70s and even lower 80s for some. Spencer, IA was able to reach 80 plus degrees and one may wonder if it could be the last such warm temperature this year. The featured chart presents the yearly range between the first spring and last fall daily high temperature of at least 80 degrees. A simple average and linear trend line is fit to both values. The trend is not very strong, but going in the right direction for those of you wanting longer a warm season of the year with the spring date coming earlier and fall date coming later. The simple fall date average is around the 6th of October, so about 50% of the time we would see another 80+ degree day after today. The forecast has cooler weather in the immediate future, but pleasant temperatures again next week.
