Climate and Weather

The Temperature chart displays average high and low values for January and July, and is designed to provide an indication of both seasonal and daily temperature variability. The Weather Risk Index indicates the calculated risk of each type of weather event occurring in the future. This risk is based on historical localized storm events and weather patterns. The national average for each type of weather event equals a score of 100, so a score of 200 would represent twice the risk as the national average, and a score of 50 would represent half the risk of the national average.
