An Arctic Outbreak

This past week, we here at OSNW3 experienced the coldest air of the season. An Arctic outbreak occurred for 4 straight days. More details on the outbreak are below. Precipitation wise, we were quite dry, even though it precipitated on 5 of 7 days. Already, this January has as many Days with Measurable Snow as last January. However, the amount of snowfall this January is much lower then last, as last January saw 23.3" fall in 10 total days and this January only 5.3" in 10 total days. An 18" difference.

Below is my version of "taking a cup of boiling hot water and hoisting it into the air as hard, fast and high as you can, and it will become an instant cloud of vapor".



The experiment was conducted in Oshkosh, WI on Friday, Jan 16, 2009 between 6:30 and 7:00am. Temperature was -13°F. Please see the full video HERE (6MB).

A few inches of fluffy snow fell this past week making the FOH slightly different looking then last week.
