Worse it gets out there the better chance we have imo. Especially due to some of our guys being questionable, bad weather will help slow down their receivers. Plus their special teams is almost as bad as ours so the bad weather will neutralize this area.
I've seen it argued the other way also at least with regard to slippery field conditions.
Since the receiver knows the run route and when to make the change of direction cut on the turf he will usually have an advantage over the cornerback or LB who must anticipate any move and immediately react. The WR acts, the CB reacts. When the field is slippery, that reaction is more likely to be compromised by adverse field conditions, so the theory goes, because it is made automatically without forethought whereas the WR can plant his cut foot deliberately, with premeditated caution, and thereby execute it more cleanly.
I'm not sure I completely buy it. Right now it looks like the wind is going to be the big factor on passing plays.
