I guess it depends on your region. I know on our place in Central Texas, if it's storming, the deer lay up. Even if it's justa good steady drizzle and intermittant showers, sitting on a stand is useless unless you expect the weather to break soon. If wet weather socks in, eventually the deer will get up to feed, but where I hunt, all they typically have to do is stand up in their bedding area to do that. I've killed a few deer in bad weather. All with a rifle, and none of them from a stand. I've had to walk them up. Samewith high winds.

I don't like to bowhunt in wet weather.
A) the water can affect your bow in very very wierd ways.Things like a wet string will really kill your arrow speed.
B) rain will wash away a blood trail, and when you're hunting 1700 acres of wide open hill country, thatcould take daysof grid searching.

I know alot of guys are hard core and will sit in their stands through a tornado. But not me. Cold weather, I'm fine all day. But if it turns off wet, that's when it gets to me.

When the weather does break, the deer will move like crazy. That's the time to be in your stand. Here's where paying attention to weather forecasts comes in handy. Especially if a storm moves in over night and it's not expected to clear untill early to mid morning. The deer will lay up through the storm during the night and at daylight they'll be all over the place.....
