A bit warm up here, ain't it? >240°C above FL240, pics included

Steam version, not in developer mode, using live weather.

Brief description of the issue:

As you can see, the SAT (outside air temp) gauge shows a very unusual weather phenomenon. This would be commonplace, perhaps if I were flying on Venus, but last I checked, Florida is still on Earth.

These conditions were encountered on descent through FL240-ish some 75 NM or so north of KMIA.

I had also experienced a similar event before (though not fully understood at the time) while cruising @FL360 over Italy. At this other occasion, the issue disappeared once I flew out of the “hot spot”

At present time, it is unknown whether this will continue and for how long, as I have paused the sim to report this very bizarre happening.

Please see OAT of 248 C at FL285?! (Impacts negatively on aircraft performance and autopilot function)
