It was a beautiful, low dew point and cloud-free day across parts of Lake Superior and Lake Michigan (& adjacent states) - perfect conditions for viewing Canadian wildfire smoke.

Interesting case of long-range transport of the #Klyuchevskoy volcanic cloud - which shows up as shades of blue in @NOAASatellites #GOESeast SO2 RGB (suggestive of ash) & shades of pink to yellow in Ash RGB (suggestive of an ash/SO2 mix): cimss.ssec.wisc.edu/satellit… #MTwx #NDwx

H/t to @ncarletta for pointing out the SIGMET (~1430Z-1830Z) by @NWSAWC for volcanic ash over eastern North Dakota and northwest Minnesota.

Can see SO2/ash signal (bright yellow in Ash RGB) on satellite upstream moving out of SK into ND. #ndwx #mnwx - Carl Jones

The latest Drought Monitor maps continue to show significant improvement across the Midwest, especially in Iowa, thanks to stormy spring weather and above normal precipitation.
