Severe weather occurred over Minnesota and Wisconsin on 2 June 2020, and the storms developed in clear skies. This allowed GOES-16 Derived Stability Indices (a clear-sky product) to provide information on the near-storm environment. The animation above combines GOES-16 Clean Window infrared (10.3 µm) imagery (where clouds exist) with Convective Available Potential Energy (CAPE) estimated from GOES-16... Read More
The NOAA Storm Prediction Center’s Convective Outlook (graphic) from 1630 UTC 23 May 2020 shows an enhanced risk of Severe Thunderstorms in northern Illinois with a sharp cutoff in probabilities to the north in southern Wisconsin. The imagery above shows the GOES-16 ABI Band 2 (0.64 µm) visible imagery (click... Read More
Consider the rocking animation (if you click on it) of 1-minute visible imagery, above, showing the high plains of West Texas from 1900-2030 UTC on 7 May 2020. A dryline is present; can you predict from this imagery where convection will initiate? (Will it? Spoiler alert: Yes, and Yes!)The Split... Read More
GOES-16 Clean Window imagery from 1800 UTC on 7 May 2020, above, suggests a frontal zone from the central Atlantic southwestward through the Florida Straits. What products can be used to diagnose the moisture differences between the dry airmass over the southeast United States/Florida and the far moister airmass over... Read More
