November Summary and a December Outlook

The first ten days of November in Oshkosh were relatively chilly but offered plenty of sunshine. Daytime highs hovered near 40 degrees while overnight lows remained at or just below the freezing mark. In my mind, almost perfect weather to begin the last month of autumn. The early month chill quickly became a thing of the past when a strong warm front pushed 60 degree temperatures back into the region. But as often as it happens in November, a strong cold front slid in behind the warm front. A 30 degree drop in temperature occurred the night of November 12th. Strong northwest winds sustained themselves for over two days which helped manifest the first snowflakes of the season. Temperatures rebounded quite nicely after the plunge providing the area with a near record breaking warm Thanksgiving. Again, however, a November gale followed the Thanksgiving warm front, this time bringing the first accumulating snow to OSNW3. I measured 0.2 inches the morning of November 25th. This snowfall occurred right on schedule. The average first measurable snowfall in Oshkosh is November 27th. As for the first inch of snowfall, that may be delayed a few days beyond the climatological average date of December 2nd.

At OSNW3 November finishes near the Oshkosh average for temperatures with a mean monthly temperature of 36.2 degrees. Precipitation ends grossly short of the Oshkosh normal for the month coming at 1.47 inches below average. Snowfall was 2.2 inches below the Oshkosh average.

With the weather patterns and cycle length of the LRC set, anyone following along can confidently project specific weather and climate conditions weeks and months in advance. From my deductions, December should begin on a warming trend. This warming trend will provide multiple shots at precipitation. Mid-month a strong front should pass dropping temperatures considerably. This drop in temperatures will last through Christmas. The days leading up to the New Year should bring yet another strong front through the area, warming the temperatures significantly and quickly pulling them back down. Depending on how much snow we have on the ground before the mid month front will determine our white Christmas chances. Trends are showing a potential snowfall on the day after Christmas which really means the event could take place on either side of the date. A potential white Christmas with flakes falling from the sky seems like a good thing in my eyes.
