The Potential Tropical Cyclone that has been moving northward through the Gulf of Mexico made landfall southwest of New Orleans, LA on Saturday 19 June as a minimal Tropical Cyclone. The animation of total precipitable water, above, from the MIMIC TPW website, shows that most of the storm’s moisture is east of... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched plots of SPC Storm Reports — and showed severe thunderstorms associated with the landfall of Tropical Storm Claudette (surface analyses) early in the day on 19 June 2021. Numerous pulsing overshooting tops were evident with some of these storms.The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below) displayed cloud-top infrared brightness temperatures as cold...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed the formation of Potential Tropical Cyclone 3 in the Gulf of Mexico on 17 Jun 2021. A low-level circulation could be seen near the storm center on Visible imagery, but deep convection was only occurring at some distance from the center.Even though... Read More
A favorable orbit geometry on NOAA-20 on 17 June 2021 meant that portions of the upper Midwest received NUCAPS soundings 90 minutes apart. This is an ideal way to monitor destabilization on a day when SPC has predicted an enhanced risk of severe weather, as shown below and at this link.Compare... Read More
