Saharan Dust Could Bring Stunning Sunrises and Sunsets to Indiana This Week

Extreme heat isn't the only thing headed our way this week.

Along with temperatures climbing well into the 90s and dangerous triple-digit heat index values, a plume of Saharan dust is expected to drift north from the Gulf of Mexico into parts of the Midwest. While it won't do much to cool things off, it could create some absolutely spectacular sunrises and sunsets across Indiana.

If you're already planning to be up early, or you'll be outside during the evening, it may be worth taking a few extra minutes to look toward the horizon.

What is Saharan Dust?

Every summer, powerful winds lift millions of tons of fine dust from the Sahara Desert in northern Africa.

That dust travels thousands of miles across the Atlantic Ocean, through the Caribbean, and into the Gulf of Mexico. Depending on weather patterns, portions of that dust plume can eventually reach the southern and central United States, sometimes extending as far north as the Midwest.

According to Houston, Texas, meteorologist Allison Gargaro, one of those dust plumes is expected to make its way north this week, and it could reach Indiana.

Why Does it Make Sunrises and Sunsets So Colorful

Those tiny dust particles scatter sunlight differently than clean air.

During sunrise and sunset, the sun sits low on the horizon, causing its light to travel through more of Earth's atmosphere. The extra dust filters out many of the shorter blue wavelengths while allowing more reds, oranges, pinks, and purples to reach your eyes.

The result can be some incredibly vivid skies that almost look edited, even though they're completely natural.

The most colorful displays usually happen about 15 to 30 minutes before sunrise and shortly after sunset.

Will Indiana Actually See It?

Forecasts suggest enough Saharan dust could reach portions of the Midwest for residents to notice more colorful skies over the next several days.

Cloud cover will play a role, so not every sunrise or sunset will be a showstopper. But if skies cooperate, this week could produce some memorable views across Indiana.

The Heat is Still the Bigger Story

As beautiful as the skies may become, the biggest concern remains the dangerous heat expected across the region.

The National Weather Service's HeatRisk forecast calls for Major to Extreme heat through much of the coming week, with parts of the Tri-State expected to reach the highest risk category by Thursday.

If you head outside to catch a sunrise or sunset, bring water, limit strenuous activity, and continue following heat safety recommendations.

Sometimes nature gives us something beautiful in the middle of uncomfortable weather. If the forecast holds, this week may be one of those times. Just don't forget to stay cool while you're looking up.
