GOES-17 “Red” Visible (0.64 µm) images [click to play animation | MP4]

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) showed a fast-moving jet of marine layer stratus moving westward from Seward-Chenega into far southern Cook Inlet in south-central Alaska on 08 June 2019. At 2245 UTC the Mesoscale Sector was shifted southward to better monitor a Gulf of Alaska storm.

This inland intrusion of marine stratus was driven by the presence of a warm thermal trough across Interior and Southwest Alaska (surface analyses) — animations of 10-minute GOES-17 Full Disk visible imagery (below) included hourly plots of surface wind barbs and air temperature. Note that some sites in southwestern Alaska had temperatures in the upper 60s to low 70s F.
