AWIPS images of the GOES-11 + GOES-12 water vapor channels (above)<\/strong> showed the large size of a major snowstorm that impacted much of the western US during the 10 October<\/strong><\/a> – 12 October 2008<\/strong><\/a> time frame. This storm dropped as much as 48.8 inches<\/strong> of snow at Cole Creek, Montana and 29.7 inches<\/strong> at Lander, Wyoming (their greatest October snowfall on record), and Glasgow, Montana received 12.8 inches<\/strong> of snow on 12 October (their heaviest snowfall for any calendar day during the month of October)<\/em>. At Billings, Montana the snow depth of 9 inches on 13 October<\/strong><\/a> was the earliest date on record for a 9-inch snow depth.<\/p>\n

AWIPS images of the MODIS visible channel and the 1.6 \u00c2\u00b5m near-IR “snow\/ice” channel (below)<\/strong> displayed the areal coverage of snow on the ground across much of Wyoming, eastern Montana, far northwestern South Dakota (including the higher elevations of the Black Hills)<\/em> and western North Dakota, stretching northeastward into portions of Saskatchewan and Manitoba on 13 October. Snow cover exhibits a darker <\/strong>signal on snow\/ice channel imagery (in contrast to supercooled water droplet clouds, which appear as lighter shades of gray)<\/em>.<\/p>\n

An AWIPS image of the MODIS Land Surface Temperature (LST) product (below)<\/strong> showed the effect of the deep snow cover on surface temperatures across much of Wyoming and Montana on 13 October — LST values within the snow swath were only in the upper 20s to low 30s F (green colors),<\/em> compared to the 60s and 70s F (orange colors)<\/em> north of the deep snow cover. The daily maximum temperature on 13 October at Glasgow, Montana was only 37\u00c2\u00ba F (which tied the record for coldest maximum temperature for that date), while the daily high temperature of 28\u00c2\u00ba F at Wisdom, Montana was the earliest date for such a cold maximum temperature.<\/p>\n

A 250-meter resolution MODIS true color image (below<\/strong>, viewed using Google Earth)<\/em> displayed the extent of the snow cover across parts of Wyoming and Montana. Note that there were a few snow-free patches located within the broad swath of snow cover (a result of the complex terrain across the region).<\/p>\n
