Hi Shannon, We wish we could be this exact, but our long-range weather predictions are not daily much less hourly. They’re made over a year in advance. If you look at the map above, the long-range predictions are meant to give a general idea of week-by-week trends of above/below normal temperatures and precipitation. For this kind of exact information, it’s best to look at the 30-day forecasts nearer the date! October’s usually such a beautiful time of year and we wish you all the best, no matter what the weather.
