How can satellite data be used to focus one’s attention to the relevant portion of an airmass when isolated convection is developing? That was a salient question late in the day on 16 July when a few convective cells developed over the upper midwest. Visible imagery (above) shows the development... Read More

The loop above shows the window channel (11 micron) imagery from the night of 15 July over Nebraska. (Also plotted: METARS, lightning, and the UWCI product) An isolated convective storm — identified accurately by the UWCI algorithm — developed over central Nebraska near local midnight. There were no severe reports... Read More

Wildfires had been burning across portions of the northern prairie provinces of Canada during early to mid July, and GOES-13 visible images (above) showed that a thick plume of smoke was drawn southward and eastward across the Upper Midwest states on 15 July 2010.A POES AVHRR false color Red/Green/Blue (RGB) image (below)...

There were three items of interest to discuss that exhibited interesting satellite signatures on 13 July 2010. The first feature was a middle-tropospheric vortex that was spinning off the coast of California, as seen on AWIPS images of 8-km resolution GOES-11 6.7... Read More
