CWG Live updates: Brief respite Friday before major heat wave develops this weekend
Welcome to updated around-the-clock by Capital Weather Gang meteorologists. Happening now: Today is much calmer than recently and less humid. Highs mid- to upper 80s with lots of sun. Maybe a stray shower in the evening. What's next? Heat builds over the weekend with 90s. Approaching 100 by early week, while humidity could make it feel near 110 to 115 degrees, which dangerously prevents our bodies from cooling. Today's daily digit — 8/10: Grading a fairly serene day generously. With the excessive heat we have ahead of us, low humidity, sunny and mainly mid-80s is actually about average warmth for this time of year. | 🤚 Your call? The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale. Forecast in detail Today (Friday): Very sunny and solidly warm, with mid- to upper 80s. A west and northwest breeze lowers the humidity a bit (dew points around 60 degrees). A few afternoon clouds bubble up in an otherwise largely sunny day. Confidence: Medium Tonight: A stray evening shower is possible. Humidity creeps upward slightly, but it's still enjoyable as lows dip into the mid- to upper 60s. Breezes should calm and clouds should fully clear out after midnight. Happy summer solstice at 10:42 p.m.! Confidence: Medium-High Tomorrow (Saturday): Above-average heat arrives with highs near 90 to mid-90s as a hot dome of high pressure begins nudging into the region. Humidity is still moderate, at worst, with dew points staying at or below the mid-60s. Skies are mainly sunny other than some high clouds at times. Confidence: Medium-High Tomorrow night: Partly to mostly clear with lows near 70 to mid-70s. A light but steady south-southwest breeze slowly pumps in more humidity. Confidence: Medium-High Sunday: Mostly sunny and hot with highs already eyeing the mid- to upper 90s. The heat dome spills into our region more fully, as hot high pressure spreads outward from the middle of the county. It may feel like low 100s with dew points nearing 70 degrees. Confidence: Medium-High A look ahead Sunday night: Only a slight shower or storm chance, otherwise it looks mainly clear and muggy. Lows sink merely into the mid-70s to near 80. Confidence: Medium Excessively hot Monday through Wednesday as temperatures try for 100, plus or minus a few degrees. Combining high humidity (dew points near 70 to mid-70s), the heat index may feel like 110 to 115 degrees during the afternoon and evening. Dangerously muggy and warm nighttime lows may only get to near 80 degrees. Please be mindful of your neighbors who might not have access to air conditioning, elderly friends and family, plus any animals or pets.

Extreme heat is heading for Minnesota this weekend. Here's what you need to know
Minnesota will experience the first heatwave of the summer this weekend as sweltering heat and humidity settle in. The National Weather Service has issued an extreme heat warning from Saturday at noon until Sunday at 9 p.m for the Twin Cities on south. Northern Minnesota is under an extreme heat warning. The NWS says the Plains and the Midwest region will see the "hottest temperatures of the season." The heat is then expected to persist across the Ohio Valley and move towards the East Coast, where it will stay for several days. In Minnesota, the feels-like temperatures could enter into the triple digits from St. Cloud on south on Satuday. Sunday, the feels-like temperature for the Twin Cities will hover around 99 degrees. A NEXT Weather Alert is in effect for both weekend days. WCCO WCCO There won't be any overnight relief from the extreme heat, according to NEXT Weather meteorologists. The forecast low for Saturday night is 79 degrees, which would shatter a 1923 record of 75 degrees. The NWS rates heat risk on a scale of zero to four, with four being the most extreme. Over the weekend, most of central and southern Minnesota will see a category three rating, which indicates that the heat will affect anyone without effective cooling or adequate hydration. Lengthy outdoor activities could also be dangerous, the NWS says. The hot weather is fueled in part by moisture blown north from the Gulf of Mexico. To stay cool, experts encourage people to limit time in direct sunlight and drink plenty of water. Cranking the AC could mean big electric bills, so Xcel Energy encourages Minnesotans to clean out the AC filter and running dishwashers and washing machines at night. contributed to this report.

Heat dome to bring record-breaking temps to NYC, much of Northeast
The city that never sleeps should get ready to sweat. The summer solstice is set to arrive on Friday, marking the start of the sunniest season of the year. The first full week of summer will also bring with it New York's first heat wave. It will begin in the mid-90s on Sunday, courtesy of 'a strong bubble of high pressure' — called a 'heat dome' — that is expected to envelop much of the eastern U.S., according to the Weather Channel. It will stave off the clouds, and in turn, the City's chances for rain, resulting in intense sunshine and a devastating humidity that will make conditions outside all the more uncomfortable. What's more, there's little sign of relief in sight. The intense heat is expected to last at least through the next 10 days or so, bringing with it record-breaking warmth for New York, where temperatures could climb into the triple digits in the coming days. According to the National Weather Service, the 'hottest temperatures are likely this weekend into the first half of next week,' with 'moderate risk of extreme heat' to follow. On Monday, it will begin to approach 100 degree weather, with a high of 97 in the forecast. And then, on Tuesday, temperatures could peak at around 101 degrees in NYC, with a string of upper-90 degree weather days after that, the NWS said. Nationwide, temperatures are forecast to shoot past 90 degrees for around 220 million people, while an additional 35 million people could face temps exceeding 100 degrees next week. The heat will be particularly fierce over the weekend across huge swaths of Nebraska, Illinois, Wisconsin and Iowa, where forecasters are warning of extreme temperature impacts. Experts have warned residents, especially the elderly and disabled, to avoid going outside in the peak heat, noting that 'heat is one of the leading weather-related killers in the United States, resulting in 'hundreds of fatalities' each year. As of early Thursday, extreme heat watches, warnings and advisories were already issued for much of the Southwest, Rockies, Plains, Upper Midwest and parts of the Northeast — and they're only likely to expand in the coming days. The rapid warm-up also brings with it the potential for a severe thunderstorm or two in the earlier evening hours, but the rain is expected to end before Friday, clearing the way for a sunny and warm weekend. Temperatures on Saturday will hover in the mid- to upper 80s before the heat wave strikes. With News Wire Services

Midwest heat dome will bring worrisome temperatures, stifling humidity to millions this weekend
Summer will make a dramatic entrance in the U.S. this week with a heat dome that will bring stifling temperatures and uncomfortable humidity to millions. The heat will be particularly worrisome this weekend across wide stretches of Nebraska, Illinois, Wisconsin and Iowa, where forecasters are warning of extreme temperature impacts. This will be the first stretch of true summertime weather for many from Midwest to the East Coast, said Tom Kines, a meteorologist at the private weather company AccuWeather. "A lot of those folks have been saying, where's summer? Well, buckle up, because it's coming," said Kines. The humid conditions will make places that exceed 90 degrees Fahrenheit (30 degrees Celsius) feel as much as 20 degrees hotter, said Kines. Heat dome forming A heat dome occurs when a large area of high pressure in the upper atmosphere acts as a reservoir that traps heat and humidity, said Ricky Castro, a National Weather Service meteorologist in Illinois. According to the NWS Weather Prediction Center, daytime temperatures will be in the 90s Fahrenheit (30s Celsius) and overnight temperatures will only drop to the mid-70s Fahrenheit (mid-20s Celsius) from the Great Lakes to the East Coast during the heat wave that's expected to last into next week. Moisture blown northward from the Gulf of Mexico is fueling the muggy weather, said Jacob Asherman, a Weather Prediction Center meteorologist. This influx of moisture is fairly typical during late spring and summer, he said. The Gulf, which shares borders with Mexico and the U.S., was renamed by President Donald Trump to the Gulf of America. The heat will be widespread into next week. On Friday, Denver could reach 100°F (38°C), according to the weather service. Chicago temperatures could reach 96 degrees (36°C) on Sunday. On Tuesday, Washington, D.C., could see a high of 99°F (37°C) and New York Central Park could reach 96°F (36°C). Several states in the Midwest could see dangerous temperature impacts over the weekend, according to a weather service measure that rates the risk from zero to four. Parts of Nebraska and Kansas will be in the highest category on the scale on Saturday, meaning that anyone without effective cooling or sufficient hydration could face health risks. On Sunday, Iowa, Wisconsin, Missouri and Illinois also see a category 4 rating. High humidity makes it hard to cool down Humidity is the amount of water vapor in the air, and the heat index is what the temperature feels like when the humidity outside is factored in, according to the weather service. When humans sweat, it cools the body down because it absorbs and removes heat as it evaporates off the skin. The air is saturated with water on humid days, which makes it harder for sweat to evaporate. Hot and humid days can be dangerous when the body is unable to cool itself off and can exacerbate pre-existing health conditions and even lead to heat stroke. Minimizing direct sun exposure, wearing loose and light-colored clothing, staying hydrated and spending time in air-conditioned spaces are ways to cool down during extreme heat, according to the NWS. Some parts of the U.S., such as Phoenix, Arizona, are famously hot without the mugginess. Phoenix and nearby desert regions experience this so-called "dry heat" due to being located far away from large water bodies, mountains that block moist air masses and weather patterns that bring scarce precipitation. Sweat evaporates faster in dry climates compared to humid ones. This can be dangerous because it is easy to underestimate how dehydrated you are, according to Johns Hopkins University and Johns Hopkins Health System. Even the crops "sweat" In places such as Iowa, crops can affect the humidity in summer months. Plants feel the effects of hot weather and some people in the Midwest are familiar with " corn sweat," which is when crops move water to their leaves and other surfaces so it can evaporate, according to the Ohio State University. Madison County, Iowa, farmer Ryan Marquardt said corn sweat is "not as bad as a sauna, but it definitely would have a sauna effect. It's humid in there (the cornfield), so you're gonna sweat." Cornfield contributions to the overall humidity are much lower compared to the humidity winds carry from the Gulf, according to OSU. Associated Press writer Jack Dura in Bismarck, North Dakota, contributed to this report.
