Some patches of dense fog have developed with the sunrise this morning. Be careful for quick changes in visibility with the morning commute. Should you encounter a fog bank, reduce speed and use your low-beam headlights to help other drivers see where you are.
Otherwise, temperatures should top out in the low 90s this afternoon. The hot conditions combined with high humidity will lead to maximum heat indices peaking mostly in the 100 to 104 degree range along and west of I-65. Heat index values in the Bluegrass counties will likely top out in the upper 90s.
The heat and humidity will continue to build on Saturday, with heat index values reaching 100 to around 105 degrees during the afternoon and evening hours. Keep heat safety in mind this weekend. Check on your neighbor, the elderly, and anyone without air conditioning. Drink plenty of water. Try to limit outdoor activities to the morning or late evening.
