To be sure, Markit's preliminary seasonally adjusted US Services PMI business activity index slipped to 56.3 in November, down from 57.1 in the previous month and the lowest reading since April.
"A fifth-consecutive monthly slowing in growth in the service sector adds to signs that the economic upturn has lost considerable momentum, though it's important to note that the pace of expansion remains robust by historical standards," Chris Williamson, chief economist at Markit, said in a statement.
"After the manufacturing PMI showed factory output growth slowing in November to the lowest since January, the weaker pace of service sector expansion puts the economy on course to grow at a 2.5 per cent annualised rate at best in the fourth quarter," according to Williamson. "With extreme weather hitting parts of the country, growth could slow even further."
Unexpectedly heavy snow, in particular, blanketed parts of New York state last week, shutting businesses for several days.

Oil rose ahead of an Opec meeting this week as investors tried to gauge the likelihood the group will decide to cut production to help prices recover.
"Whether they are going to cut is up in the air," Paul Crovo, a Philadelphia-based oil analyst at PNC Capital Advisors, told Bloomberg NEws. "I won't make big bets either way. There is a lot of expectation that Opec does need to cut. That's the perception, and it's going to drive the market."
