With all the weather sources available pre-flight and in-flight, I think their time has come and gone. I listen to them in flight when Center advises of them, but there's no way I can know where "From 65 SSE of GLD to 25 NW of WKS to 10 S of NOW to DCA to ..." actually is, and more times than not it's either outside my flight path or it's above me/below me. With a healthy pre-flight and iFly's excellent decoding and graphical depiction of ADS-B info with SIGMET's, AIRMET's, METAR's, TAF's, and regional/CONUS radar, there should be no way for known flight conditions (turbulence, icing, TS, etc.) to sneak up on a smart pilot.
