Wind Observations from 11/29/11

On Tuesday, November 29, 2011, a strong low pressure system moved northeast across Ohio, into the Eastern Great Lakes. The tight pressure gradient around the low pressure system lead to strong, northerly, winds along Wisconsin's Lake Michigan Shoreline.  A Wind Advisory was issued for the counties along the lake shore. A Wind Advisory means that sustained winds could reach or exceed 30 mph and/or wind gusts could be 45 to 57 mph. The highest winds were within a few miles of the lake shore, farther inland Wind Advisory criteria was not met. Here are the highest sustained winds and peak gusts reported in Sheboygan, Ozaukee, Milwaukee, Racine, and Kenosha Counties.

The image above is valid at noon on 11/29/11. The black lines are lines of constant mean sea level pressure (MSLP), the closer they are together, the faster the wind speed. The color shading shows wind speed, as forecasted by the RUC80 model. The pink and purple colors represent lighter winds, while the light blue colors represent strong winds.
