TEMPERATURES

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).
