Play Dangerous Heat Wave To Set Record Highs

A dangerous, widespread heat wave will bake the central and eastern U.S., bringing the hottest temperatures of the year and uncomfortably muggy air to the Midwest and Northeast that in some areas could last into much of next week.

Already, daily record highs were set Thursday in Salt Lake City (104 degrees), their first triple-digit high of the year.

Here are the main takeaways from the forecast:

Heat Alerts

– The National Weather Service has already issued extreme heat watches, warnings and heat advisories for large swaths of the central and eastern U.S., as you can see in the map below. Some cities in these alerts, including Omaha, the Twin Cities, Chicago, Kansas City, St. Louis, Detroit, Cincinnati, Pittsburgh, Philadelphia and New York City.

– The highest level heat alerts are now called “extreme heat” watches and warnings. You can find more about those changes here. These alerts indicate that heat illnesses are expected to spike when they are in effect. Minneapolis and Omaha are just two of the cities that are already expected to see dangerous conditions.

Heat Timing

Here’s when we expect the worst of the heat:

– Plains and upper Mississippi Valley: Lasting through Sunday

– Rest of Mississippi Valley: Could last through much of next week

– Rest of Midwest: Relief will arrive by Tuesday in the northern Great Lakes, but heat could last much of next week in the Ohio Valley

– Northeast: Ramps up Sunday, with some relief in New England, eastern Great Lakes by Wednesday. Mid-Atlantic and Appalachians heat could last much of next week

(MAPS: 10-Day Forecast US Highs/Lows)

How Hot?

– Highs in the 90s will spread over much of the country east of the Rockies, except for the far northern tier.

– Dozens of locations, especially in the Northeast, will be within striking distance of daily record highs, especially Sunday through Tuesday.

– A few locations could approach or top 100 degrees during the heat wave. Boston, New York City, Philadelphia and Washington, D.C. could flirt with the century mark during the peak of the heat wave next week. Some of those locations could do so multiple days during the heat wave.

– Omaha is hosting the College World Series this weekend. Highs there will push 100 degrees both Saturday and Sunday. Sunday’s game between LSU and Coastal Carolina could be a scorcher. Temperatures will warm closer to 100 during Sunday afternoon’s game.

– New York’s Central Park hasn’t reached 100 degrees since July 18, 2012, according to the National Weather Service. Philadelphia hasn’t reached 100 degrees in June since 1994. Boston’s last 100-degree high was on July 24, 2022.

Forecast Highs Next Week

Humid, Too

– Oppressive humidity will accompany the heat wave.

– This will particularly be the case in the mid-Mississippi and Ohio Valleys, but also into the upper Mississippi Valley, Great Lakes and at least parts of the mid-Atlantic and Northeast.

– That means the heat index, or feels-like temperature, will be in the triple digits on one or more days for some cities in the Midwest and Northeast this weekend into early next week.

– This also means that overnight temperatures will not cool off or provide any relief from the daily heat.

Forecast Dew Point (This map depicts where the muggiest air is expected in the central and eastern U.S. The higher the dew point, the more humid the air. In general, dew points of 70 degrees or higher are very humid. )

What You Should Do

– Heat is the number one weather killer in the U.S., with hundreds of fatalities each year.

– The combination of heat and humidity lingering into the night for several days in a row could be dangerous for those without access to air conditioning, especially in the cores of larger cities.

– Check on family, friends, the elderly and those with chronic illness who live without access to air conditioning.

– If possible, avoid being outdoors for long in the peak heat of the afternoon.

– If not, take frequent breaks, avoid strenuous activity, drink more water than usual and wear loose, lightweight clothing.

This map shows the National Weather Service Heat Risk forecast, an experimental index developed with the CDC to quantify potential impacts of excessive heat. The “extreme” level of impact is defined as “rare and/or long-duration extreme heat with little to no overnight relief that affects anyone without effective cooling and/or adequate hydration.”

Why So Hot?

– This heat wave will be triggered by a change in the jet stream pattern.

– Specifically, a strong bubble of high pressure aloft known as a heat dome will develop over the eastern U.S.

– Sinking air near the center of this heat dome suppresses clouds, allowing the intense sunshine this time of year to heat the ground and air above it most efficiently.

– Southerly and southwesterly winds will also tap hot and humid air from the South into the Midwest and Northeast.

– This heat dome will only slowly weaken and “flatten out” in the East in the week ahead.

By Monday, we start cooling down as a cold front moves over Nebraska. Highs continue on trending cooler down into the upper 80s and lower 90s with heat index in the mid to upper 90s.

Monday is still a First Alert 6 Weather Day for the potential of severe thunderstorms in the early morning and mainly the mid to late afternoon hours. The cold front will produce isolated thunderstorms around sunrise Monday morning then diminish off by mid morning before becoming scattered by the afternoon.

Some storms may produce quarter-size hail and damaging winds reaching 60 mph. If we get heavy downpours, there could be some minor flooding. The tornado risk is low.

A Marginal risk has been issued for the area late Sunday night and Monday afternoon.

Isolated t-storms look to form overnight into early Monday morning. (wowt)

A chance of strong storms are possible Monday afternoon. (wowt)

After the storms, we will back to near normal in the 80s and 90s for the rest of the week with moderate to high humidity.

The upcoming stretch of hot afternoons and warm mornings will make it very hard for homes without air conditioning to cool off. Check in with your older friends, neighbors, and family members to make sure they are safe and staying cool through the weekend. Even for the younger crowd, if you have outdoor yard work or want to go for a run, make sure you do it early in the morning and drink plenty of water. Keep pets with you inside, and make sure they have access to clean water all day.

After a warm start to Sunday, near 80 degrees, near-record heat is expected in the afternoon. The record high in Omaha for June 22 is 100, which was set in 1930. We likely fall just shy of that. The humidity will easily push the heat index closer to 105. We also stay mostly sunny and windy throughout the day.

Then, a cold front will start to approach the area from the northwest, and it could push a couple isolated and strong storms at areas northwest of Omaha late Sunday night.

Before the cold front arrives in our area Monday, we likely have enough time to hit 90 degrees. The cooler air will reach northeast Nebraska first, keeping some spots there in the 70s! If the cold front speeds up, Omaha may only hit the mid 80s. The cold front will also fire off numerous showers and storms, especially in the second half of the day. The possibility for a faster cold front would keep the best chances for rain along and south of I-80. A slower front would bring better rain farther northwest. A couple of these storms could be strong enough to produce pockets of hail and strong wind.

The cold front will then stall across eastern Nebraska and western Iowa, and it will trigger more rounds of scattered showers and storms through the rest of the workweek.

A lot of us will see those showers and storms again Tuesday. Those that stay dry long enough will warm into the mid 80s.

About half of the region will see more rain Wednesday and Thursday as scattered showers and storms continue at times. This keeps highs in the 80s.

It’s uncertain exactly how long it will take the front to fully push out of the region, but it could be gone as early as Friday. For now, we’ll lower the threat for showers and storms Friday and Saturday, but we’re keeping them around just in case the front gets stubborn.

If we fully dry out into the weekend, we could get back to 90 on Saturday.

NEW YORK– An expansive heat dome that has already set dozens of high-temperature records Friday has its sights set on baking over 30 states with potentially life-threatening heat through the first week of summer.

The sprawling area of high pressure began scorching the Plains Thursday and Friday, breaking several heat records in Colorado, Rapid City, South Dakota and parts of Nebraska. Denver tied its record high of 99 degrees on Friday while Pueblo reached 103.

HUMID HEAT OR DRY HEAT: WHAT IS WORSE?

Heat alerts are in effect in the Plains through Sunday, with Duluth, Minnesota, Minneapolis, Sioux Falls, South Dakota and Omaha, Nebraska under extreme heat warnings.

HEAT KILLS MORE AMERICANS THAN FLOODING, TORNADOES, HURRICANES OR LIGHTNING

Dangerous heat spreads into the Northeast next week

As the heat dome spreads east, it’ll cast a wide net over more than half of the country, causing potentially life-threatening temperatures.

This weekend the heat will spread across the Midwest and into the Great Lakes, where high temperatures will surge 10-20 degrees above average.

By Sunday, more than 200 million Americans will see temperatures at or above 90 degrees with various heat alerts spanning from Colorado to Maine. High humidity with dew points reaching into the 70s if not near 80 degrees will make temperatures feel well over 100 degrees in cities like Chicago, Louisville, Cleveland, Nashville and Raleigh, according to the FOX Forecast Center.

The high humidity will also make for warm nights, offering very little relief from the extreme daytime temps.

In the Northeast, widespread heat alerts are in place through Wednesday as temperatures are forecast to soar to levels not always seen during the month of June.

Extreme Heat Warnings – the most dire heat alert from the National Weather Service – now stretch from Philadelphia up the Atlantic coast through New York City into Boston. Pittsburgh and parts of West Virginia are also under similar warnings so far.

Triple-digit temperatures are forecast in New York City, Washington, D.C., Philadelphia and Hartford, Connecticut on Tuesday.

New York City and Philadelphia have not hit 100 in any month since 2012. In New York City, the temperature had only reached 100 degrees in June three times prior, most recently on June 27, 1966. In Philadelphia, it has occurred 10 times before, most recently on June 15, 1994.

From the Gulf Coast to Massachusetts, heat indices will also top 100 degrees, making it dangerous for those working or playing outside without proper hydration or cooling options.
