Weather Alert Day: Dangerous heat possible into Saturday

RAIN FORECAST UPDATE:

Saturday has started off mostly dry, with overnight storms being the only precipitation so far, as more showers and storms slowly enter from the west. The outflow from this activity may inspire more storm chances later in the day, with a similar threat for gusty winds at most. Coverage is highly uncertain, but a washout is not expected, and there's a good chance of dry time for evening firework displays. Monitor the forecast for updates.

The ABC 17 Stormtrack Weather Team has issued a Weather Alert Day for the potential of dangerous heat through Saturday. All of this week will present a risk of dangerous heat. Heat indexes will largely range from 98-103 degrees.

Upper-level high pressure has developed, pushing the jet stream northward. A steady supply of Gulf moisture will keep our humidity high.

This strong high-pressure system looks to stick around across the southeast through the weekend keeping temperatures locked in the 90s. Gulf moisture will make the air feel very stagnant and thick with dew points in the 70s.

The combination of high dew points and high temperatures will yield heat indices between 100 and 105 degrees through Saturday. Daily heat indexes in the triple digits and overnight lows in the 70s will wear on anyone without access to effective air conditioning, especially those sensitive to heat-related illnesses.

If you're traveling to Kansas City or St. Louis, you should expect it to feel hotter in each city throughout the week than in rural areas of Mid-Missouri. The expansive pavement and lack of green cover can create hotter environments, especially over time, as buildings and pavement hold heat overnight, leading to greater warmth during the day.

Try to limit your time outdoors during peak heating hours from late morning through dusk. Wear light-colored, loose-fitting clothing, and stay hydrated with water or electrolyte drinks, especially if you work outdoors.

Make sure pets have cool shelter and plenty of water, and avoid taking them on longer walks during the hottest part of the day. Never leave children or pets unattended in hot vehicles and always check the back seat.
