Insider Blog: Triple digit heat index values return for the weekend before a brief cool down next week
SATURDAY AM UPDATE: A Heat Advisory has been extended further into the weekend for Central Missouri. Less cloud cover expected the next few days will allow the heat index to breach triple digits on Saturday and Sunday afternoons.
SETUP
After a toasty end to the week, we're gearing up for yet another hot weekend in Mid-Missouri with continued above-average temperatures. Friday marked the 43rd day at 90 degrees or above for the year, surpassing our 20-year average of 36 days.
A stalled front triggered a few showers and storms Friday afternoon, but a quiet start to the weekend is expected as winds pick up from the south, keeping dew points in the 70s again on Saturday. That humidity in combination with highs in the mid-90s will send the heat index above 100 degrees the next two days.
Sunday may feature a few more clouds ahead of a slow moving cold front that will bring rain and a cool down by Monday, but temperatures will still likely reach the mid-90s. Dew points near 70 will keep the heat index between 101-103.
WHAT TO DO
This weekend, try to limit outdoor exercise to around sunrise or sunset. Stay hydrated by drinking more water than usual, and supplement with low sugar sports drinks with electrolytes. If you must work outside during the day, plan to take plenty of breaks.
Be aware of the signs and symptoms of heat exhaustion and heat stroke. Heat exhaustion is characterized by excessive sweating, feeling dizzy, nauseous, and crampy with a weak pulse. Ways to treat it include getting into a cool room, drink water, and take a cool shower.
Heat stroke can be deadly and is different from heat exhaustion in that the person will stop sweating, skin will be dry, hot, and red, and the person will have a rapid, strong pulse. The person may become unconscious and 911 should be called if heat stroke is suspected.
Always check the backseat of your car for pets and children. The temperature inside the car can rise up past 130 degrees when air temperatures are at 95 after just a few minutes with the engine shut off. Pets need cool shelter with plenty of cool water. Limit their walks to early morning and near sunset, and try to keep their paws off hot pavement as extreme temperatures can cause burns to their paws.
