Snowstorm Dec 30

Image
A Winter Storm Warning was in effect this morning (Dec 30). We had a quick 0.5" accumulate between 6-7am, but the band shifted northward and the snow completely stopped. Find out what went down in NW Wisconsin as the system moved east with Dirk and Derek as they actually got some good snowfall.

.UPDATE...AN UPDATED SET OF ZONES WILL BE OUT ASAP WITH THE SOUTHEAST PART OF THE FORECAST AREA DOWNGRADED FROM WARNING TO ADVISORY BASED ON EXPECTED SNOWFALL TOTALS.

Oshkosh was included in the downgrade. However, the snow picked up again and since it started out as a Warning, might as well keep updating what once was, eh?!

Parade of Storms

Image
I got the idea for the title from Dewdrop, but I think the same idea was being used pretty much everywhere. Regardless. Simply put, that's what it's been. I suppose, since the overall pattern has changed, I would consider the parade over. The parade started back on Dec 17, ushering in system after system each producing moderate amounts of snowfall. However, this last system brought with it some very mild air and rain. OSNW3 lost several inches of snow pack with this last system. The max snowdepth during the parade hit 14" twice, back on Dec 21 and again on Dec 26. At observation time on Dec 28 the snowdepth was 7". This parade has helped many towns in the area break their all-time record snowfall for the month of December. I am confident Oshkosh's record will officially fall once the month is all said and done as well.

December Snowfall Record Imminent

Image
This past week was snowy and cold for the most part. Four out of the seven days OSNW3 saw accumulating snows, and on six of the seven days had min temps in the single digits with three of those six being below zero. The lowest max temp ever recorded at OSNW3 in the month of December fell on Dec 15, 7.0°, which was the first time the max temp didn't rise out of the single digits since Feb 20, 2008 when it was 9.0°, 300 days ago. Also recorded was the lowest temp ever in December at OSNW3, on Dec 21, when it dipped to -5.3°, AND, as of the 24hr observation period ending Dec 21, OSNW3 has recorded 25.7" of snowfall, which ties the official record for the month of December in Oshkosh.

Snowstorm - Dec 19, 2008

Image
Another Winter Storm Warning was all up ons. As the storm moved through I documented it's progress over OSNW3. During the early morning of Dec 19, a snow less hole opened up in the storm directly over Oshkosh, which I believe kept my totals on the lower side.

First "actual" day of Winter

Image
The snowy start to December continued into this past week, dropping a good dose on Dec 8-9, but fizzled out as the week wore on. Temps hovered below average until the system currently affecting us rolled in. Temps maxed out above freezing on Dec 13 and the precipitation that fell, fell in liquid form. Our snowpack is sustaining itself fairly well to this point... (OSNW3 December Observations)

First "actual" day of Winter (Defined)
Dec 10 was the official FDW at OSNW3. Last year, the FDW at OSNW3 was Dec 9 (2007/2008). Comparing this December to last, and the days preceding Winter, they seem quite similar (2007/2008). Congrats to DoubleJ for predicting this outcome way back on October 27, 2008 at 4:05:30 pm.…
