1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Day Cloud Phase Distinction RGB images with an overlay of GLM Flash Extent Density (above) showed a glaciating (brighter shades of green) to glaciated (pale shades of yellow) lake effect snow (LES) band streaming inland off Lake Erie on 17 November 2023. There were 4 brief periods of lightning activity seen just south of the Buffalo,... Read More

5-minute GOES-16 (GOES-East) Day Cloud Phase Distinction RGB images with overlays of GLM Flash Extent Density, LightningCast Probability and Buoy/METAR reports (above) showed glaciating (brighter shades of green) and glaciated (pale shades of yellow) cloud bands streaming eastward and southeastward off Lake Ontario and Lake Erie on 08 October 2023. Some of these cloud bands were producing lake effect... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed Ophelia for a few hours after it became a Tropical Storm at 1800 UTC on 22 September 2023. The low-level circulation center (LLCC) was initially exposed, but deep convection just to the west began to increase in coverage and intensity as it... Read More

GOES-18 (GOES-West) Day Land Cloud Fire RGB, Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.3 µm) and Near-Infrared “Vegetation” (0.86 µm) images with an overlay of the Fire Power derived product (a component of the GOES Fire Detection and Characterization Algorithm FDCA) (above) showed that the Hossitl Creek wildfire complex northeast of Fort Nelson (CYYE) — in far northeastern British Columbia...
