The National Weather Service says there is a chance for a cooler summer in Louisville, but the forecast is still uncertain.Meteorologist John Denman says spring rainfall can cool off the summer months. But weather for Louisville is harder to predict, because the city lies on the border of several of those regions.
"Northern states like Montana through Wisconsin have had a very wet spring and that has some correlation into the temperatures developing during the early summer" says Denman, "in other words a wet spring tends to have very wet ground and produce cooler daytime highs than areas with dry ground for example.”The northern states that have seen a lot of precipitation will likely see a cooler summer while the southwestern states that have seen little rain will probably see a hotter summer than in the past.Louisville falls on the edge of cool predictions, but much of Kentucky falls outside prediction areas. Last summer was the hottest on record for the city of Louisville, with an average temperature of 83 degrees.The chart from the National Weather Service shows areas of cooler than average summer temperatures and areas of hotter than average summer temperatures.
