GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) revealed the formation of a standing wave cloud along the Minnesota shoreline of Lake Superior on 08 January 2019. This cloud feature was formed by a vertically-propagating internal gravity wave that resulted from the interaction of strong post-frontal northwesterly flow with the topography of... Read More
A winter storm produced 6-8 inches of snowfall from the eastern Texas Panhandle to central Oklahoma on 03 January 2019 (NWS Amarillo | NWS Norman). On the following day, GOES-16 “Red” Visible (0.64 µm) images (above) revealed the areal extent of the snow cover, with significant melting occurring by the late afternoon hours. The snow... Read More
GOES-16 (GOES-East) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) showed the development of an orographic standing wave cloud — downwind of the Appalachian Mountains (topography) — over the Mid-Atlantic states on 17 December 2018. North of the wave cloud, widespread short-wavelength mountain waves were seen at lower elevations... Read More
A large midlatitude cyclone moved from the southern High Plains to the Lower Mississippi Valley during the 13 December – 15 December 2018 period (surface analyses) — GOES-16 (GOES-East) Low-level Water Vapor (7.3 µm) images (above) showed the evolution of this system.The corresponding GOES-16 Water Vapor images with plots of hourly surface wind gusts are...
