GOES-16 CONUS sector imagery, above, captured from CSPP Geosphere (link), over Tropical Depression Fred just north of eastern Cuba in the Atlantic Ocean, shows a ragged circulation with very little convection in the center (click here to download the mp4 above). Fred has been disrupted by its passage over the terrain... Read More
The Storm Prediction Center has placed much of southern Wisconsin in an Enhanced Risk (below; click here to view the image at the SPC website). By 1800 UTC, below, surface dewpoints in southern WI/eastern Iowa were at torrid levels, and mid-level lapse rates were steep as depicted in the SPC Mesoanalysis below.NOAA-20’s orbits... Read More
The animation above shows NUCAPS sounding availability plots from sequential NOAA-20 overpasses on 5 August 2021. Stations that are north of about 39 N will occasionally see profiles from two sequential overpasses, as was the case above at Buffalo NY, and also Pittsburgh PA. A benefit of NUCAPS soundings is...

Microwave estimates of total precipitable water over the western Pacific Ocean (available here) show a moist airmass — out of which Typhoon In-Fa (seen near Taiwan in the animation) emerged — over the western Pacific Ocean. (The circulation of Tropical cyclone Cempaka is also apparent near the Gulf of Tonkin)... Read More
