Suomi-NPP True-Color imagery (above, from Real Earth) from 17-20 March 2018 show the break-up of pack ice in eastern Lake Erie. (Clouds with the big Nor-easter prevented views on 21-22 March). Winds at both Erie and Buffalo switched to an easterly component during this time, which may have helped the ice fracture. Silt... Read More
Thunderstorms developing in the warm sector of a low pressure system (surface analyses) produced tornadoes, large hail and damaging winds (SPC storm reports) across parts of the Deep South late in the day and into the night on 19 March 2018. GOES-16 (GOES-East) “Red” Visible (0.64 µm) images at 30-second intervals (above) showed numerous overshooting tops... Read More
One of the Level-2 products in AWIPS is Sea-Surface Temperature. This is created hourly on the Full Disk scale, and is shown above. The image above toggles between the default enhancement (from -5º to 40º Celsius) to one that is more appropriate for mid-March (-5º to 30º Celsius), and then with the ABI Band 2 (0.64 µm) Visible Image. This allow change allows for features in the... Read More
Thunderstorms developing east of an advancing dryline (surface analyses) produced large hail (SPC storm reports) across south-central and eastern Texas late in the day on 18 March 2018. GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed well-defined overshooting tops and above-anvil cirrus plumes associated with this severe convection.In the corresponding GOES-16 “Clean” Infrared Window (10.3 µm)...
