GOES-16 (GOES-East) “Red” Visible (0.64 µm) and Day Cloud Phase Distinction RGB images (above) showed widespread elevated convective banding that was helping to enhance snowfall rates — with some locations reporting 1.5 to 2.0 inches per hour — across parts of Minnesota, Wisconsin, Lower Michigan, Iowa and Illinois on 16 February 2023. There was no GLM indication... Read More
US Space Force EWS-G1 — formerly GOES-13 — Infrared Window (10.7 µm) images (above) showed Cyclone Freddy in the South Indian Ocean, after it re-intensified to a Category 4 storm at 0000 UTC on 15 February 2023. Freddy then briefly peaked at 145 knots at 0000 UTC on 16 February... Read More

Strong winds (with gusts in the 60-85 mph range) in the wake of a cold front lofted... Read More
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Red” Visible (0.64 µm) images (above) include plots of Derived Motion Winds (DMW) — and showed the rapid offshore transport of cold arctic air across the southern Cook Inlet, Shelikof Strait and northwestern Gulf of Alaska on 12 February 2023. The fastest low-level (Surface – 900 hPa) DMW speed was... Read More
