Ah yes, November! A most interesting month. In many ways it's like March only November comes in like a lamb and can leave like a lion! Expect pretty nice and warmish temperatures through the first two weeks of this month and then watch out as the night times get seriously cold just before the end of the month (see graph of Nov 2010).
The average high is 57F and the average low is 33F where I live in southwest Missouri. However, that figure is skewed somewhat with the warmer stuff coming early on, followed by rapidly cooling conditions late. The reason; more and more aggressive incursions of cold air from the northwest in the form of fronts that also bring moisture as a consequence. Expect rainfall to be close to four inches as a result. Note: Last year was a little dry at about 2.50 inches!
So, think cold and damp as one way to characterize November. Ergo, not my most favorite month, but still way out ahead of the evil trio that is December through February. Please remember though, that just as as this month is often humid, so it is that cold dry air will soon follow. Time to make sure you have a humidifier in good working order. I have an old Duracraft DH799 unit that uses three filters that have to be replace every year. I also need to remember to order a bottle of anti-bacteria solution. Sometime in early December, I'll have this unit running pretty much full time to help keep the air in my home moist. This actually helps my heat pump out as the air will hold heat better if the humidity is at 40% or there about. For more on that, please see my article on moisture control.
