High temperatures will range close to record values for parts of the region today. The records for today date back to the Dust Bowl era in 1933, when Louisville hit 96 degrees, Lexington hit 95, Bowling Green hit 102, and Frankfort had a reading of 100. The latter two records look safe for today, but the forecast for Louisville is to tie the record at 96 and Lexington to get close at 93. The map below shows high temperatures for selected locations throughout the region. The heat index is forecast to rise into the upper 90s for regions along and west of the Interstate 65 corridor. East of it, heat indices should top out in the lower 90s.
Temperatures on Wednesday should be similar to Tuesday. The forecast high for Louisville is 96 degrees, which if correct would break the record for that date, 95 degrees set back in 1953. For Lexington, the high is forecast to be 93 degrees, which again nears the record of 95, also set back in 1953. High temperatures in Bowling Green and Frankfort are forecast to be 94 and 93, respectively. These forecasts are well below the records for that date, 100 degrees at both locations, set back in 1933. The heat index will be a little higher Wednesday afternoon, as surface moisture will be slightly higher. Heat indices will rise into the upper 90s to 100 degree range along and west of Interstate 65, whereas points to the east will get into the mid 90s.
