A steady monthly temperature pattern occurred. The Average Maximum/Minimum/Mean Temperatures for November 1st-15th vs. 16th-30th were almost exactly the same: 52.0°/42.4°/47.2° vs. 51.9°/42.4°/47.2°. The month’s warmest weather waited until Thanksgiving time when the Minimum Temperature only dropped to 54.9° on the 22nd, several degrees above the Normal Maximum Temperature for the date. This warmth was balanced just a few days prior when the Min. Temp. dropped to 33.8° on the 19th (the low for the month), the coolest temperature since 33.5° on March 19, 2017. The Average Diurnal Range for the entire month was only 9.6°, certainly indicating a damp, cloudy month; the greatest day was 15.4° (19th), the least only 2.4° (28th).
On average, November is the wettest month of the year and 2017 was not a disappointment as nearly 9 inches were observed. Measurable rain fell on 25 days, with 22 of these being ≥0.10″ but just one ≥1.00″. For the calendar year, the 2017 precipitation total is now up to 57.67″ and the number of days with measurable rain (≥0.01″) stands at 157.
The month saw no clear days, 9 partly cloudy days, and 21 cloudy days. As is expected with such an overcast, rainy month there were 25 days with Fog, 4 being heavy (<1/4 mile visibility).
There were 2 days with pea-size hail (3rd & 5th) but no thunder heard.
