\"AWIPS<\/a><\/p>\n

A mesoscale convective system (MCS) moved southward across southern Wisconsin during the morning of 11 July 2008<\/strong><\/a>, producing a well-defined bowing segment along the southern flank. As the MCS continued to decay into the late morning hours, the signature of a weak Mesoscale Convective Vortex or MCV (see <\/strong>Interesting Clouds on Satellite: “Mesoscale Convective Vortex”<\/strong><\/a> <\/strong>from the NWS Milwaukee)<\/em> became apparent on AWIPS images of the GOES-12 visible and IR channels (above, upper 2 image panels; <\/strong>see also a GOES-12 visible animation<\/a> <\/strong>from Dave Santek, SSEC)<\/strong><\/em>. While the presentation of the MCV was fairly impressive on the GOES-12 satellite imagery, this feature was much less obvious on the Milwaukee\/Sullivan radar base reflectivity and base velocity data (above, lower 2 image panels)<\/strong><\/em>.<\/p>\n

Northerly winds gusted to 37 mph<\/strong> at the Madison airport KMSN<\/strong> (41 mph on top of the SSEC building<\/strong><\/a> in downtown Madison)<\/em> as the bowing segment convection moved through; however, it is interesting to note that Juneau KUNU<\/strong> later reported a southeasterly<\/em> wind gust of 43 mph<\/strong> at 17 UTC (Noon local time)<\/em> as the MCV passed over that area; apparently a boundary layer “wake low” was responsible for producing this brief period of gusty southeasterly winds (which also included gusts to 20 mph at West Bend KETB<\/strong> and 17 mph at Watertown KRYV<\/strong>)<\/em>.<\/p>\n

A comparison of MODIS true color and false color images from the SSEC MODIS Today<\/strong><\/a> site (below)<\/strong><\/em> showed finer detail in the cloud structures of both the leading edge of the convective outflow (the aforementioned bowing segment)<\/em> and the MCV. The MCV signature was comprised primarily of lower to middle level clouds, and became more obvious as the canopy of high-level cirrus clouds (cyan colors on the MODIS false color image)<\/em> began to dissipate as the MCS decayed.<\/p>\n
