Great Lakes lake surface temperatures, 0735 UTC on 23 September 2020, as well as zoomed-in views of the individual lakes (Click to animate)<\/p><\/div>\n

Suomi-NPP’s descending pass at ~0730 UTC (shown here<\/a>, from this site<\/a>), had an ideal path — moving south from far eastern Upper Michigan to western Lower Michigan — to view all five Great Lakes.\u00a0 Sprawling High Pressure<\/a> and the attendant clear skies meant that a good basin wide view of the lake temperatures was observed, as shown above. (DB imagery from this pass is also available for a short time at the CIMSS DB ftp site<\/a>) These ACSPO (Advanced Clear-Sky Processor for Ocean) SST fields are available to NWS offices via LDM fields. The default color bar in AWIPS has been changed so that only temperatures between 45\u00ba F and 70\u00ba F are shown<\/p>\n

Lake Temperatures in the imagery above range, for Lake Superior<\/a> from 47.5\u00ba (east of Minnesota) to 66\u00ba (just off southwest Upper Michigan); for Lake Michigan<\/a> from 57\u00ba (east of Sheboygan WI) to 67\u00ba (mid-lake, east of Chicago); for Lake Huron<\/a> from 55\u00ba (in northwestern Georgian Bay and also northwestern Lake Huron) to 65\u00ba (far southern Lake Huron); for Lake Erie<\/a> from 63\u00ba (western Lake Erie) to 69\u00ba (central Lake Erie); for Lake Ontario<\/a> from 62\u00ba (western Lake Ontario) to 67\u00ba (eastern Lake Ontario). <\/p>\n

This view of the Great Lakes from early in September<\/a> (also from the CIMSS DB site, processed with CSPP<\/a>), shows — with a color bar that ranges from 41\u00baF to 86\u00baF — much warmer water, especially in Lake Superior where the coolest mid-lake temperatures were in the mid-50s. Storms and vertical mixing since early September have cooled the surface waters.
