GOES-16 visible animations from the morning of 8 February show ice motion along the south shore of Lake Superior, moving northeastward away from Duluth Harbor, and also east and northeastward to the south of Madeline Island. Winds at this time were from the west or southwest at 15-20 knots as... Read More
GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images with plots of hourly surface weather type (above) showed the formation of a well-defined cold conveyor belt that moved westward across parts of the Northeast US during the 01 February – 02 February 2021 period. This moist airstream helped to enhance snowfall rates, with 2-4 inches... Read More
GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images (above) displayed the signature of a leeside cold frontal gravity wave (reference) as it moved rapidly southward across the Plains (surface analyses) on 14 January 2021. Post-frontal wind gusts in the 50-70 knot range were seen, with a peak gust to 91 knots (105 mph) in eastern Wyoming.In... Read More
GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) displayed cloud streets across the Bering Sea — cloud features that frequently occur in areas with a strong flow of cold air over warmer water. This northerly flow of cold air across the Bering Sea was due to a strong pressure gradient between... Read More
