Using XM radio to avoid Tstorms can be pretty hazardous unless you

It is odd that he was taking so much advice from ATC. XM Wx should easily
keep you clear of level 5-6 stuff, and is much better than depending on
controllers to avoid big CBs.

Last I checked many controllers only have transponder indications with no
weather on their display at all. Even if they can paint the weather, they
have no obligation to help you with weather if they are under heavy
workload.

When sitting up around 10 to 12,000 I've had approach from several
airports ask me what I was seeing and then relayed it to aircraft in
those areas. Two I remember are Toledo and Kalamazoo. I also had
At Kazoo (at 8000 IIRC) the front and line of thunderstorms was within
a couple of miles of the airport. For Toledo the aircraft reporting
the rough ride, and lightning were in storms quite a ways north and
not showing on Toledo's RADAR.
Minneapolis Center asked about visibility over the UP of Michigan and
over Lake Michigan on a night flight with thunderstorms coming out
over Lake Michigan from the West. OTOH they may have just breaking up
the monotony of making sure I was still awake as the storms were quite
a ways from me, (but they were visible and moving way slower than
forecast).
