GOES-17 (GOES-West) Mid-level Water Vapor (6.9 µm) images (above) showed the circulation of an anomalous middle-tropospheric cutoff low over the northwestern portion of Alaska on 12 June 2020. A Potential Vorticity (PV) anomaly associated with this low was causing the dynamic tropopause — represented by the pressure of the PV1.5 surface —... Read More
Showers developed over southern Wisconsin late in the day on 12 June 2020. What satellite products could be used to anticipate where the showers would develop? The animation of visible and radar, above, shows that the storms initiated near a boundary (mostly stationary) that separated Lake Michigan-influenced air with less... Read More

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
