The weather gods are conspiring against us

The last three July 1st long weekends, we have gone camping with a group of friends ranging from a group as small as three families to a group as large as six families (I think we were 22 people that year).

The first year, it was cold (and I mean, see your breath at night cold) and it rained on and off for three days.

The second year started with a torrential rainstorm the first night, followed by cool temperatures and on and off rain for three days.

The third year, we moved the trip to a different park in hopes of having better weather luck. We did have a bit of sun, but we had a lot of rain -- more daytime rain than we'd had in the past three years. And it wasn't that warm out either.

This year, the group came to a consensus to move the trip to the August long weekend, in hopes that the weather will be better. That being said, check out the long-term forecast for this weekend:
Had we gone camping this weekend, we would've likely gone from Thursday until Sunday. Thursday is looking to be on the cooler side, but after that it's nothing but hot temperatures and sunshine.

If our 'lucky' streak continues, anyone want to take a wild guess on what the weather forecast might look like for the August long weekend?
