October Top Ten Finish

The last few days of October were no indication of what type of conditions prevailed for most of the month. Temperatures were down, and precipitation was up. Concluding the previous entry, October 2009 finishes in the top 10 for both the coolest and wettest of all-time. The active weather pattern of this October has got many thinking about what this Winter may have in store for snowfall. I am hoping for an above average season. See more details below...

The October 2009 Top 10 Performance
This October has been one to remember. It has landed itself in the top ten all-time, since 1893, for coolest mean temperature and precipitation. A feat that stands alone. Analysis of the Winters which have followed Oshkosh's 9 wettest and coolest Octobers shows that 5, respectfully, of those Winters produced less snow than the long-term average. The lowest seasonal snowfall total came in at 17.9" while the highest seasonal snowfall total topped 100" coming in at 103.6". My end conclusion is that a wet and cool October may foreshadow an average Winter snowfall.

The NWS GRB ranked a hand full of Northeast WI cities mean temp and precip for October. Turns out that the OSNW3 data crunch was almost identical to the Oshkosh Airport data. Amazingly we had the same mean temp of 44.9° and only differed by .13" of total precipitation. Click here for the NWS rankings.

Lake Michigan Waves
Last Thursday very strong N/NE winds brought the largest waves I've documented on Lake Michigan and the Sheboygan shore. The Deland park breakwall provided the location for mighty wave crashes. At times, the spray from the crashes would seem higher than the lighthouse and the lighthouse would disappear from sight. The wind was whipping (sustained winds of 20mph, gusts of 31 mph - link) at the time I was present, which was between 445 and 545 in the afternoon. Please click on the photo for the entire set of photos and videos.

Front Of House
Things are rapidly becoming bare. This past storm system brought very windy conditions during it's exit and blew most of the remaining leaves off their branches. The fire bush is bare, which is almost a week ahead of last year.
