When strong storms appear in Forecast Models, it is tempting to trace back in the atmosphere where the system originates. The water vapor animation above, from GOES-13, ends with the future East Coast Storm developing over the lower Mississippi River Valley (where it produced severe weather). The rocking animation, below, shows... Read More
Subtropical Storm Alex (NHC advisory archive) formed in the far eastern Atlantic Ocean on 13 January 2016. Animations of GOES-13 (GOES-East) 0.63 µm Visible (above) and 10.7 µm Infrared images (below) showed the initial evolution and northeastward motion of the storm. Alex is only the 4th known January tropical or subtropical storm... Read More
As a Low pressure center moved away from the coast, and a High pressure system approached from the west (link), cold air swept south along the east coast of the United States and produced light snow/flurries over Tidewater Virginia and the Outer Banks of North Carolina on Tuesday, 5 January...

The GOES-13 and GOES-15 Imager provides routine observations at five wavelengths, including 6.5 µm, a wavelength that is sensitive to water vapor absorption (SHyMet lesson). The YouTube animations below show full-disk GOES-13 (GOES-East) and GOES-15 (GOES-West) water vapor images at 3-hour intervals for every day during 2015. GOES-15 shows the remarkable... Read More
