‼️DEVELOPING: RADAR SHOWS JET FLEW INTO A STORM CORE AT 35,000 FEET
Analysis of Miami NEXRAD radar shows the Learjet 60 (N722BD) entered a thunderstorm core near Wellington at about 12:48 PM ET, just before it crashed in Palm Beach County.
At 35,000 feet, radar echoes around the jet jumped to 34 dBZ, with a 52 dBZ core below it and storm tops near 47,000 feet. Tracking data shows the jet climbed about 450 feet inside the core, then went into a spiraling dive and crashed 76 seconds later.
Minutes earlier, the crew told Miami Center they were in moderate turbulence and “managing the ice” at −53°F, and asked to climb out of the precipitation. Moments later they declared a Mayday, reported an overspeed, and said they were banking 60 degrees.
All 9 people on board did not make it. The NTSB is investigating, and the cause has not been determined.

We're saddened to hear about the tragedy involving a Learjet 60 near West Palm Beach, Florida on Sunday evening, November 1. Weather was likely a contributing factor; while the NTSB has a long investigation ahead, here's what the meteorological and flight tracking data tell us:

BREAKING: Destructive, strong tornado in France! An incredible supercell tornado occurred in the department of Aude, France around 4:25-4:30 p.m. local time Monday.
It touched down near/northwest of Limoux and moved east toward the city. It was associated with a rotating supercell thunderstorm that formed ahead of a messier storm complex/clusters. It propagated eastward, likely gobbling up extra low-level spin north of the Pyrenees Mountains.
It was very likely a significant (EF2+) tornado, and may have caused EF3 damage. Winds probably exceeded 150 mph (240 km/h). Complete destruction of some homes has occurred.
DERNIÈRE MINUTE : Tornade forte et destructive en France ! Une incroyable tornade de supercellule s’est produite dans le département de l’Aude, en France, vers 16 h 25-16 h 30 heure locale lundi.
Elle a touché le sol près/au nord-ouest de Limoux et s’est déplacée vers l’est en direction de la ville. Elle était associée à un orage supercellulaire en rotation qui s’est formé en avant d’un complexe/amas orageux plus désorganisé. Elle s’est propagée vers l’est, absorbant probablement un surplus de rotation de bas niveau au nord des Pyrénées.
Il s’agissait très probablement d’une tornade significative (EF2+), et elle a peut-être causé des dommages de type EF3. Les vents ont probablement dépassé 150 mph (240 km/h). La destruction complète de certaines maisons a eu lieu.
Le monstre de l’Aude. L’entonnoir de la tornade qui frappe le département est remarquable. Si vous accélérez l’image, on découvre la rotation notable du phénomène en cours sous un orage violent. Vidéo de Denis Maréchal (Facebook) @BFMTV
