Two, 'largely, weather related' can mean almost anything. More then half of the U.S. population is not even affected by snow. The bad GDP numbers were partially affected by the weather, not caused exclusively by the weather.
Three, the consumer spending numbers are for April...and have little/nothing to do with the bad winter weather.
The economy as of April, sucks. I am not saying it won't pick up (especially if the Fed slows the taper). But as of April, it sucks.
