UPS - Adverse Weather Conditions? Its Partly Cloudy and Sunny?

I was supposed to get my shipment from Cigar Auctioneer in today but it is stuck in Little Rock, Arkansas due to what it labels "Adverse Weather Conditions". The weather says it is 70F and partly cloudy with 0 precipitation in the past 24 hours. I don't mind if its a day or two late but there has to be some other explanation than weather. From what I can tell they have had nice weather there recently? Anyone live there and can give me an insiders scoop as to if the weather is bad or something else is going on? I am not complaining or nagging I just am confused as to why it would say Adverse Weather Conditions. Any help would be greatly appreciated.
