GOES-16 (GOES-East) True Color Red-Green-Blue (RGB) images from the AOS site (above) revealed the arrival of a dense high-altitude smoke plume from the north, which cast a late-day shadow onto the top of a more aged layer of lower-altitude smoke over the Upper Midwest on 30 May 2019. These smoke layers were... Read More

GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) revealed the mesoscale cyclonic circulations of actinoform clouds (or “actinae“) within the marine boundary layer stratocumulus cloud field over the central Pacific Ocean on 30 May 2019.This type of cloud feature was originally identified in TIROS-V imagery over the Pacific Ocean in 1962 (below),...

Due to an overlap of GOES-17 (GOES-West) Mesoscale Domain Sectors, images were available at 30-second intervals — and “Red” Visible (0.64 µm) images (above) showed the development of thunderstorms over southeastern Oregon, southwestern Idaho and northern Nevada on 29 May 2019. Some of these thunderstorms produced heavy rainfall and small hail in southwestern Idaho, and... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) depicted supercell thunderstorms forming along and south of a quasistationary frontal boundary (surface analyses) which produced a variety of severe weather (SPC Storm Reports) across eastern Kansas and far western Missouri late in the day on 28 May 2019 — including the long-track EF-4 tornado that...
