The National Weather Service (NWS) issued a Heat Advisory, originally in effect until 7 p.m. across much of Mid-Missouri. However, the temperature risk drops off as a cold front moves through the area triggering rain and thunderstorms.
The NWS reports the cold front is moving through the region and interacting with the very warm, moist and unstable air, resulting in scattered thunderstorms. A few of the storms could be severe during the afternoon and evening. The primary threats will be damaging winds and large hail.
Heat and humidity in advance of the cooler temperatures may cause heat stress during outdoor exertion or extended exposure. The very young, the elderly, those without air conditioning and those participating in strenuous outdoor activities will be the most susceptible. Also, car interiors can reach lethal temperatures in a matter of minutes.
A Heat Advisory means a period of hot temperatures and high humidity will occur. This combination will create a situation in which heat-related illnesses are possible, especially for those living in homes or apartments that lack air conditioning.
People in the advised area should avoid poorly ventilated areas and prolonged work in the sun. Also, keep plenty of liquids on hand and try to stay in an air conditioned environment. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to the early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.
To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9-1-1 immediately.
Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.
