Radar, planning software and routing have all gotten much, much better in the last decade.

I believe even as late as 2007 or 2008, ATC was limited in the deviations it could do due to the track system still in use in certain areas. Once the ARTCC/TRACONs were updated, ATC in the US now has way more capability and capacity to re-route traffic around storms. I forget when the last ARTCC refresh/rebuild happened.
