I am not a pilot of any type, just an interested observer of aircraft.
It does seem that many of the high profile helicopter accidents involve poor conditions, which would seem to indicate that SBs approaching of setting down and waiting for the weather to clear, or continuing by car and fetching the helicopter later is the wisest course of action. However I can also understand why many would not want to do that and would prefer to continue flying on the "it will get better soon" or "it won't happen to me" optimitic thoughts.
