Will UPS attempt to deliver my package on Saturday? ?

Okay so I ordered some new phones with a whole new provider on Wednesday early in the day. I paid for the UPS 2nd day air because there was a lot of snow here Wednesday so I figured it'd give them enough time. The shipper sent out the order about 2 hours after placing it I got all the tracking info, everything was fine till it reached Indianapolis, Indiana where its been sitting for 2 days now. The tracking info hasn't been updated it just says "weather may cause delay" today is saturday I'm just wondering if the tracking info just isn't updating & they will attempt to deliver my phones today? It wouldn't be a big deal but since we switched cell phone providers my fiance brought his # over and they shut off his old service so he has no phone.
