Yellen nods to cold weather, says unclear impact on economy
"Since my appearance before the House committee, a number of data releases have pointed to softer spending than many analysts have expected," Yellen told a Senate Banking Committee hearing, referring to a February 11 testimony.
"Part of that softness may reflect adverse weather conditions, but at this point it's difficult to discern exactly how much," she added. "In the weeks and months ahead, my colleagues and I will be attentive to signals that indicate whether the recovery is progressing in line with our earlier expectations."
