The Bank of America Chicago Marathon takes place this weekend in the city of Chicago and, with thousands headed to the third largest city in the nation to compete and participate in the festivities, I am sure many want to know what the forecast holds for the big race weekend. I am sure this is especially true considering that it's been so rainy this morning in Chicago while many runner are doing their final preps for the race. Well, its not looking to good for the runners in the Windy City, as severe weather and excessive rain is in the forecast for today, with heavy rain lingering in the forecast over the next few days. Temperatures over the next few days will also be very depend on whether its raining. With no rain, you can expect conditions to be warmer. With rain, its will likely be cooler across Chicago and the region. Saturday looks to be a drier day, which will allow for more sun and temperatures in the low 70s. Officially on race day Sunday, temperatures will be in the near 60 around the beginning of the day with temperatures peak in the upper 60s by afternoon. More rain and isolated thunderstorms are in the forecast. All the best to the runners reaching and exceeding their wildest dreams this weekend. For WeatherNation, I am Meteorologist Marcus Walter.
