The National Weather Service in Jackson (KY) has issued a Hazardous Weather Outlook for eastern Kentucky.
A Heat Advisory is in effect from 12:00 PM Friday (July 19) to 8:00 PM Saturday, July 20.
Thunderstorms are possible today (July 18) into early evening. Some storms could produce heavy rainfall.
The heat and humidity will combine to yield heat indices of between 100 and 105 degrees from Friday afternoon through the first part of Saturday evening. Heat indices of around, or slightly exceeding, 100 degrees will be possible again Sunday afternoon.
An expansive dome of high pressure will develop and cover much of the area to end the work week and start the weekend. This oppressive regime will be aided by warm air aloft preventing showers or storms from forming for most of the area, providing little in the way of relief. As a result, heat indices will exceed 100 degrees for many hours both Friday and Saturday afternoons with maximum readings surpassing 105 degrees in a few locations.
Accordingly, a Heat Advisory has been issued for all of eastern Kentucky from Friday afternoon through the first part of Saturday evening. This advisory replaces the Excessive Heat Watch that was in effect for this time.
Consecutive days of heat indices above 100 degrees to around 105 degrees could have a cumulative impact on some individuals, especially those who engage in prolonged outdoor work or other activities. Also, car interiors can reach lethal temperatures in a matter of minutes. Never leave pets, children, or the elderly unattended in parked vehicles. The extended period of high heat and humidity can worsen the effects of heat stress.
A Heat Advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check on relatives, pets and neighbors.
