A nighttime Aqua MODIS Water Vapor (6.7 µm) image (above) showed the well-defined circulation of a midlatitude cyclone that was centered over northwest Iowa at 0814 UTC (3:14 am local time) on 21 June 2018. Contours of RUC model equivalent potential temperature along the 310 K isentropic surface indicated that a Trough... Read More
Persistent convection over northern Wisconsin, Minnesota and upper Michigan late Saturday (16 June)/early Sunday (17 June) caused significant flooding. The animation above shows GOES-16 ABI “Clean Window” Infrared Imagery from 0200-0600 UTC on 17 June. Note the persistence of the cold overshooting tops over western Bayfield County in northwestern Wisconsin! A... Read More
A comparison of Aqua MODIS Visible (0.65 µm), Near-Infrared “Cirrus” (1.37 µm), Water Vapor (6.7 µm) and Infrared Window (11.0 µm) images (above) showed widespread transverse banding along the northern and eastern periphery of a decaying Mesoscale Convective System (MCS) that was moving from Iowa into Illinois and Missouri on...
