MODIS true color imagery from the SSEC MODIS Today site (above, viewed using Google Earth) shows extensive snow cover over the higher elevations of southern California (and Baja California in Mexico) on 15 February 2008. According to media reports, this snow closed sections of Interstate 8 (between Alpine and Ocotillo) for more than 12 hours on the previous day; as much as 8.5 inches of snow was reported at Cuyamaca Peak (elevation 4820 feet) in San Diego county.

An AWIPS image of the MODIS Land Surface Temperature (LST) product (below) indicated that LST values were in the 30º-40º F range (green enhancement) in the region of the snow cover, compared to the much warmer bare ground areas to the west and to the east where LST values were generally between 60º and 70º F (orange enhancement).
