03 August 2008 marked the 22nd  consecutive day of daily high temperatures of 90º F or higher at Denver, Colorado (the old record was 18 consecutive days, set back in 1874 and 1901). AWIPS images of the MODIS Land Surface Temperature (LST) product (above) revealed daytime LST values as high... Read More

AWIPS images of the GOES-12 10.7 µm IR channel (above) showed a cluster of strong thunderstorms moving eastward across parts of Nebraska and South Dakota on 03 August 2008 — at one point these storms exhibited an “enhanced-v” signature on the IR... Read More

Parts of interior Alaska experienced heavy rainfall and significant river flooding during the last week of July 2008; AWIPS  composite images of the GOES-11 and GOES-12 water vapor channels (above) showed a rather unusual moisture plume — one having a long northwesterly fetch — stretching from the Russian arctic coast...

There are a number of satellite signatures that denote areas of potential turbulence, and AWIPS images of the GOES-12 10.7 µm IR channel on 27 July 2008 (above) displayed two of the more common indicators: rapidly developing convection, and transverse banding. A decaying mesoscale convective system was moving southeastward across... Read More
