My permits are for the 5th as well.
Looking at the weather reports have me discouraged. I have been caught exposed in a lightening storm before, and I don't ever want to do that again.
More concerning than the weather reports are trip reports from Face Book detailing crazy shifts in the weather...rain, hail, and lightening. And that happening on the days it showed clear weather on the forecast.
May be cancelling...don't know if it's worth the risk.
