\"GOES-16<\/a>

GOES-16 “Red” Visible (0.64 \u00b5m, left)<\/em> and Shortwave Infrared (3.9 \u00b5m, right)<\/em> images, with surface station identifiers plotted in cyan [click to play MP4 animation]<\/p><\/div>The combination of strong winds and low relative humidity prompted the SPC to forecast elevated to critical fire weather<\/strong><\/a> potential across parts of the Upper Midwest on 29 April 2018. A Mesoscale Domain Sector<\/strong><\/a> was positioned over the region, providing data at 1-minute intervals — and “Red” Visible (0.64 \u00b5m<\/strong><\/a>) and Shortwave Infrared (3.9 \u00b5m<\/strong><\/a>) images (above)<\/strong><\/em> revealed the smoke plumes and thermal anomalies or “hot spots” (black to yellow to red pixels)<\/em> associated with some of these larger fires. The most prominent fires were located in southeastern Manitoba later in the day (including the largest fire EA015<\/a><\/strong>, which was listed as Out of Control).<\/p>\n

On the Visible images, also note the hazy signature of blowing dust that developed from the northern Red River Valley of North Dakota and Minnesota into southern Manitoba — with winds gusting in excess of 50 knots<\/strong><\/a>, the surface visibility dropped to 3 miles at Grafton ND (KGAF) and Winnipeg International Airport (located just northwest of station CXWN in southern Manitoba).<\/p>\n
