During the last few months, I have made it a tradition to wrap up the previous 30 or 31 days and compare it to average, then see where we're going next. It's a monthly weather summary from the Burlington International Airport. I dive into the high temperatures, lows, precipitation, and some other noteworthy items.
Let's start off with temperatures since it was such a big departure from average:
October high temperatures were above average, by a value of 1.6 degrees Fahrenheit. This isn't wildly abnormal, but it's noteworthy.
Low temperatures were even warmer! Temperatures at night held more than two degrees warmer than the October norms. For these two charts above, I take the 31-day average for highs and lows, then take the actual numbers and take the average. My colleague Nick Johnston noted the month of October was 2.0 F warmer than average. Overall 2011 to-date is running 1.5 F warmer than average. *FYI average is data from 1981-2010.
October 2011 was not wetter than average, which is opposite the way 2011 has been going thus far. The precipitation was close, a mere tenth of an inch away from the norm.
The wettest 24-hour period in October was on the 14th and 15th where 1.33" of rain fell. We measured 0.1" of snow in late October in Burlington, while much of the rest of the state had much more!
In Burlington it either rained or snowed 14 out of the 31 days.
It was clear/sunny only 7 days out of 31.
The warmest temperatures was 80 degrees on the 9th, and the coldest was 27 degrees on the 29th.
In the upcoming 8-14 days (through November 19) there's a good chance of our area being warmer than average. There's an above-average chance for being wetter too.
Synoptically, sea surface temperatures over the Pacific continued to be about 1 C cooler than average. This is known as a La Nina pattern. For our area I believe it will mean our temperatures will remain about average to 1 F warmer, and precipitation will remain average to above-average.
