The main weather headline around these parts is the lack of snow. One measurable snowfall in the first 18 days. It is something we haven't witnessed at OSNW3 since we began recording climate data back in November 2006. However, when it comes to averages, it is expected to trend the opposite way after an all-time record setting monthly snowfall in 2008. For snow enthusiasts there is light at the end of the tunnel as snow chances do exist in the final two weeks of the month. For a basic overview of the chances of snow remaining this month visit the OSNW3 LRC analysis blog or get modelitis by visiting the OSNW3 Weather Breif below.

OSNW3 ends December with 1.79 inches of precipitation and again surpasses the Oshkosh monthly average making it the fifth consecutive year in doing so. However, December of 2010 is the driest December at OSNW3 on record since genesis in 2006. Our snow pack took a huge hit in recent days as the past two low pressures western track pulled in very warm air for December and with the warm air the dreaded form of precipitation this time of year, rain. These conditions have quickly decimated a strong 8 inch snow pack. Climatology for December since 1893 can be found here . The first couple weeks of 2011 will bring seasonal temperatures and slight chances for below average precipitation according to the CPC.

Max temperatures hovered around average for the most part this past week. With the warmer temps, though, we did see four measurable snowfalls. Nothing major as three of the four were under an inch. We are currently 4.2" above the December monthly snowfall average and for the third consecutive year have exceeded that average. Last December Oshkosh broke an all-time monthly snowfall record, recording 35.6" here at OSNW3 and 33.7" officially at the WWTP. An amazing 18 days recorded measurable snowfall ( Days with Measurable Snowfall ), and comparing last December to this December we are two days behind. Up to this point, last December had 10 days with measurable snowfall while this December has had only 8, which is still above the Oshkosh average (6.1 days).
