1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) include an overlay of GLM Flash Extent Density — and showed the distinct circulation of a middle-tropospheric closed low (400 hPa analysis) as it moved northeastward across Illinois and Indiana into southern Lower Michigan on 25 March 2023. Isolated clusters of brief lightning activity were... Read More

JMA Himawari-9 Dust RGB images created using Geo2Grid (above) spanned the period from 2100 UTC on 20 March to 2350 UTC on 22 March 2023 — and showed a large area of dense blowing dust (brighter shades of magenta to pink) across parts of eastern Mongolia and northern/northeastern China (eventually crossing...

GOES-16 (GOES-East) Air Mass RGB images (above) include 3-hourly surface analyses of pressure and fronts — which showed the progression of a late-season Nor’easter during the 13 March – 15 March 2023 period. This storm produced heavy snowfall and high winds across much of the Northeast US (including a gust to 81 knots or 93 mph at Mt. Washington NH).As... Read More
