Not A "Normal" November, Or Is It?

Image
Typical for the month of November is the extreme difference we endure between the highest high and lowest low. Thus far OSNW3 has recorded a maximum temperature of 62.4 degrees and minimum temperature of 14.7 degrees. Currently we are just over 3 degrees above the monthly mean and just under 2 inches below the monthly precipitation total. As for what is to come, "The feature that produced the wind storm should come back in some form in the first 10 days of December" - Jeremy Nelson of WeatherWatch12. Welcome back The Great Lakes Cyclone, perhaps? Jeremy has issued his winter outlook and will be pinning down the actual length of the LRC during the month of December. Think snow!

Diurnal Temperature Variation & The Northwoods Snowstorm

Image
Late this past week our mild temps took a dive back to seasonal. It was getting out of hand as our overnight minimum temperatures hovered around our average maximum temperatures. The cooler temperatures boost our chances for our first measurable snowfall to take place soon. The average date for OSNW3's first accumulating snowfall is Nov 20. That said, a trend that continues here at OSNW3 for the month of November is the lack of precipitation. We've received just 0.22 inches. 2010 marks our 5th season observing and of the four preceding Novembers all have failed to reach the average monthly precipitation total. As for what lies ahead, the forecast is calling for below average temperatures with equal chances of precipitation.

November Pleasantry & Lezak's Recurring Cycle; A view from OSNW3

Image
November is beginning as it did the past two years with an up and down feel trending on the dry and mild side with nothing extreme happening. At my location we have only recorded 0.03 inches of precipitation thus far and our mean temperature is about a degree above the average. On a more exciting note, we did register our First Flakes of the season at OSNW3 on Nov 4 at 6:45pm. It came down in the form of graupel, which I learned is a matter of opinion if it actually counts as a "first flake" or not, but we here at OSNW3 have counted it as "First Flakes" of the season. Also, on Nov 5 the temperature maxed out at 38.9 degrees. The Last time the max temperature stayed below 40 was on Apr 9, 2010 when it was 39.7 degrees. 212 days prior. The 6-14 day forecast concludes we will see below average temperatures with above average precipitation after this beautiful weather of late moves on out. Think snow!
