Severe Thunderstorms in the Midwest and Arizona; Heat Continues in the Southeast and Southwest

Thunderstorms, some severe, may lead to scattered instances of flash flooding across the Midwest and Ohio Valley and southern Arizona. The threat will shift to the Mid-Atlantic coast on Thursday. Dangerous heat persists in the South and Southeast while building into the Southwest. Overnight lows will be so warm that little-to-no relief from the scorching daytime highs will be available.

Watches and Warnings:

The Storm Prediction Center in Norman Oklahoma forecasts the risk for severe weather across the country several days in advance. These outlooks help to inform you if there is a risk for severe weather. If severe weather becomes likely, a watch can be issued, alerting you to the increased risk for severe weather. If severe weather is possible in your area, you should have a plan on where to go for shelter and be ready to act if severe weather were to occur.

Tornadoes and Tornado Safety

Colorado is no stranger to tornadoes. Tornadoes have occurred in most areas of the state, but historically most of the tornadoes occur along and east of Interstate 25 where heat and moisture in the lower atmosphere are often more abundant. Tornadoes can occur at every hour of the day, but most occur between the afternoon and evening hours. An easy phrase to remember for tornado safety is to Get In, Get Down, and Cover Up. Get inside a sturdy building, get down to the lowest floor or most interior room, and cover your head.

Flood and Flash Flood Safety

Flash flooding refers to a dangerous sudden rise in water along a creek, river, or a normal dry land area. Flash floods result from heavy rainfall, sudden breaks in river ice jams, and dam or levee failures. Flash floods can occur within a few minutes or hours...and can move at surprisingly high speeds, striking with little warning. Flash floods are quite destructive because of the force of the moving water, and the debris that accumulates in flood waters, such as trees and boulders, which can destroy roadways, bridges, and buildings. Nearly half of all flash flood fatalities are vehicle related. Do not enter a flooded roadway, instead Turn Around Don't Drown.

Damaging Winds and Large Hail

Damaging winds and large hail are major risks in Colorado. Tornadoes are often the headline story, but damaging straight-line winds can also injure and kill animals and humans. These winds are usually caused by an area of air within a storm which is quickly cooled by precipitation, or by the evaporation of precipitation. This area of cooled air, which is heavier than the surrounding air, accelerates downward. As the cool air slams into the ground, it spreads out from the area of impact. This process, in extreme cases, can result in wind speeds exceeding 100 mph. Meteorologists call these winds downbursts. Hail often occurs in Colorado. Hail forms within storms as liquid water freezes in the cold mid and upper levels of the storms. The hailstones are kept aloft by strong updraft winds for a time, and then cascade to the ground. In Colorado, hailstones vary from pea size, around 3/8 of an inch in diameter, to softball size, around 4 1/2 inches in diameter.

Lightning and Wildfires

Thunderstorms produce some of the most dangerous weather on Earth, including tornadoes, flash floods, large hail, and destructive straight-line winds. However, the most dangerous aspect of thunderstorms in Colorado is usually lightning. Lightning usually kills and injures more people in Colorado than any other thunderstorm hazard. In addition to producing human casualties, lightning also ignites most forest and rangeland fires in the Centennial State. Many of these wildfires occur when lightning is generated from thunderstorms which produce little or no rainfall. This type of lightning is referred to as dry lightning. The safest thing for you to do, if you are outside and lightning or thunder begins to occur, is to immediately get inside a substantial fully-enclosed building. The best defense to protect yourself against a lightning strike is to plan ahead and avoid being caught where you might be vulnerable. Check the weather forecasts prior to venturing out, especially if you are heading into the mountains.
