CIMSS: 35-year anniversary of the sinking of the Edmund Fitzgerald

Surface wind speed and direction valid 12 UTC November 10, 1975, approximately 13 hours before the last communication from the ship.
Yesterday marks the 35-year anniversary of the powerful Great Lakes storm that was responsible for the sinking of the SS Edmund Fitzgerald (on 10 November 1975).
Since the first operational geostationary weather satellites (SMS-1 and SMS-2) were relatively new back in 1975, the CIMSS Regional Assimilation System (CRAS) model was utilized to generate synthetic IR satellite images to provide an idea of what the satellite imagery might have looked like for this intense storm (CRAS model surface winds).

A 48-hour sequence of synthetic IR images (above) shows the evolution of the model-derived clouds at 1-hour intervals.
As part of CIMSS's involvement in GOES-R Proving Ground activities, CRAS synthetic forecast satellite imagery (IR and Water Vapor channels, below) is currently being made available in an AWIPS format for interested NWS forecast offices to add to their local AWIPS workstations (via LDM subscription).

VISIT training is also available on the topic.
