1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and Day Cloud Phase Discrimination RGB images (above) showed the development of a mesovortex over southern Lake Michigan on 12 February 2021. The surface flow supporting the mesovortex formation was well-depicted by hourly RAP40 model output. Note that there was a lack of GOES-16 Visible (Band 2) Derived Motion Winds created... Read More
The animation above shows GOES-16 Band 4 (1.38 µm, “Cirrus Channel) Imagery along with GOES-16 Derived Motion Wind vectors and Turbulence observations. Significant and widespread turbulence occurred. Of particular interest is a arced feature that appears in the GOES-16 imagery from northern Mississippi through western Tennessee and into south-central Kentucky. ... Read More
Beginning on 06 February 2021, the GOES-15 satellite was brought out of storage for a 14-day period of imaging (as part of its annual checkout activities). On 10 February, a comparison of Water Vapor images from GOES-17 (6.9 µm) and GOES-15 (6.5 µm) showed mountain waves over southeastern Wyoming and... Read More
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
