<\/a>GOES-16 Visible (0.64 \u00b5m) images, with hourly surface reports [click to play animation]<\/p><\/div>** GOES-16 data posted on this page are preliminary, non-operational data and are undergoing testing **<\/em><\/p>\n GOES-!6 Visible (0.64 \u00b5m<\/strong><\/a>) images (above)<\/strong><\/em> revealed the presence of a well-defined lake breeze boundary on 14 June 2017<\/strong><\/a>, which extended well inland from Lake Superior across northeastern Minnesota and northwestern Wisconsin. This shallow pool of lake-cooled air was acting to suppress the formation\u00a0 of inland cumulus clouds and\u00a0 maintain marine layer fog\/stratus over the water and the adjacent coast\u00a0 — both of which slowed the warming of surface air temperatures. For example, in northwestern Wisconsin, Hayward Sawyer County Airport (KHYR<\/strong><\/a>) reached an afternoon high temperature of 81\u00ba F, while not far to the northwest Duluth Sky Harbor Airport (KDYT<\/strong><\/a>) only reached an afternoon high of 52\u00ba F as fog and stratus shrouded the site and held temperatures in the 40s F much of the day. Note that a few bore-like wave structures were seen in the lake stratus.<\/p>\n A comparison of Suomi NPP VIIRS Visible (0.64 \u00b5m) imagery at 1803 UTC with RTMA<\/strong><\/a> surface winds at 18 UTC (below)<\/strong><\/em> showed the flow and cloud features associated with the lake breeze.<\/p>\n
