An Embraer 175L took off from Tampa shortly before 1900 UTC on 20 July 2022. About an hour into the smooth flight (as shown here, i.e., around 1945-1950 UTC), turbulence injured about 7 passengers that resulted in a diversion to Birmingham AL (news article; Here is the flight path). The animation... Read More

IFR (Instrument Flight Rules) Probability estimates the likelihood that IFR conditions are occurring by fusing GOES-17 satellite data with model output. The satellite-derived products give output of low IFR, (LIFR), IFR, and Marginal Visual Flight Rules (MVFR). In aviation, the difference between these classifications is generally:Low Instrument Flight Rules (LIFR): Ceilings are less than 500 feet above ground... Read More

At the request of AWC and WFO HNL, the turbulence probability fields for AWIPS have been changed (the website — here — is unaltered as of now). The turbulence probability is split into 3 layers that are each 3000 feet thick: 30000-33000 feet ; 34000-37000 feet; 38000-41000 feet. The AWIPS plugin... Read More

GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images with pilot reports of turbulence — with and without contours of RAP40 model Maximum Wind Speed (above) showed an anomalously-deep 500 hPa trough over the Southern Plains, where there was an anomalously-strong 250 hPa jet streak developing along its forward (eastern) edge. A number of pilot reports of moderate to... Read More
