No shortage of satellite meteorology topics today over the Upper Midwest and Great Lakes regions! A look at the GOES-12 visible channel animation<\/strong><\/a> (below, left)<\/strong><\/em> reveals the following features: (1)<\/strong> fingers of morning fog in the river valleys of southwestern Wisconsin, (2)<\/strong> areas of smoke aloft from wildfires burning in Canada and the Pacific Northwest, and (3)<\/strong> afternoon lake breeze boundaries that acted as a focus for thunderstorm development in both Wisconsin and lower Michigan.<\/p>\n

(1)<\/strong><\/em> As we have noted previously, these narrow fog features are often not detected using the 4 km resolution GOES fog\/stratus product, but the 1 km resolution MODIS<\/a> <\/strong>fog\/stratus product (with observations overlaid)<\/strong><\/em><\/a> is able to resolve the river valley fog in southwestern Wisconsin.<\/p>\n

(2)<\/strong><\/em> While the smoke signature is subtle on the GOES-East (GOES-12) visible imagery, we can take advantage of a more favorable forward scattering geometry using the GOES-West (GOES-11)<\/strong><\/a> satellite to better see the areal extent of the smoke early in the day (GOES-11 animation)<\/strong><\/em><\/a>. The smoke is also depicted as a large plume of high MODIS aerosol optical depth (AOD) extending from southern Canada to the Upper Midwest (below, right)<\/strong><\/em>. In addition, the thick smoke contributed to a colorful sunset (and sunrise) here in Madison (photo 1<\/em><\/strong><\/a> | photo 2<\/strong><\/em><\/a>). <\/strong><\/em><\/p>\n

(3)<\/strong><\/em> Narrow pockets of instability were noted on the GOES sounder lifted index (LI)<\/strong><\/a> derived product (values of -7 to -8 F), in the vicinity of the lake breeze boundaries in both Wisconsin and Michigan; hail up to 1 inch in diameter<\/strong><\/a> was reported from the afternoon lake breeze convection in Wisconsin and Michigan.<\/p><\/blockquote>\n
