Severe thunderstorms exhibiting Above-Anvil Cirrus Plumes over the Dakotas

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed two severe thunderstorms along the North Dakota / South Dakota border region, which exhibited Above-Anvil Cirrus Plumes  (reference | VISIT training).A longer animation of GOES-16 Visible images with plots of time-matched SPC Storm Reports is shown above, with GOES-16 Infrared images...

Blowing dust in southern Bolivia

GOES-16 (GOES-East) True Color Red-Green-Blue (RGB) images created using Geo2Grid (above) showed plumes of blowing dust originating from dry river beds along portions of the Río Grande O Guapay and Río Parapetí in southern Bolivia on 04 July 2020. Strong northerly winds developed across that region, just east of the... Read More

Using GOES-R Level 2 stability products to help nowcast the cessation of convective initiation

The animation above shows GOES-16 visible imagery (Band 2, 0.64 µm) and stability indices. Initially an obvious gradient in stability is present where isolated convection is developing over southwestern Wisconsin. As the gradient relaxes, the convection dissipates even though instability is, in general increasing. A radar animation (clipped from RealEarth)... Read More
