News stories are saying that the pilots tried to abort the takeoff too late "due to weather" and crashed in a field just beyond the airport. What kind of weather would you just see/learn about during your takeoff that would cause you to abort?

Possibly a wind shear, airliners are required to have these for awhile now, if a downward column of air was entered just prior to rotation the plane would have likely never gotten airborne. This has been the cause of a few bad accidents but usually an airport would be able to advise a flight prior to liftoff to hold off on leaving. Maybe this airport lacked the proper equipment to detect it.

But pilots know very well what the cutoff point is for aborting a takeoff, whoever is not flying the plane during takeoff is supposed to call out when they reach that point. It sounds like they got airborne so would it have been safer to just proceed with a takeoff, maybe "max thrust takeoff" or whatever?

I wonder how expensive that weather equipment is, this wasn't exactly a Cessna taking off.

Wow, maybe my above criticism is misplaced if the pilots managed to save all souls onboard.

I think TOGO power, (take off go around) is around 90% so there is not that much extra push to get and turbo-prop engines take a few seconds to spool up. Your correct, usually when "V1" is called that is the last possible time to abort if that is a pilot's intention. Sounds like they attempted to rotate, but due to wind shear were getting shit for lift. This is all speculation on my part but here is what one of the passengers had to say about it,
"Another passenger told Foro that the plane took off in a driving rainstorm but started falling soon after"
Anyway we will know more very shortly since both pilots survived and flight data recorders can verify or dispute their stories. Pilots are put under a lot of pressure to not cancel or delay flights, of course all of them will say "safety first" but in reality this sometimes gets pushed off a tad to not be "that" guy that costs the airline a bunch of $$ due to a flight not leaving or leaving late.
