CWG Live updates: Warming up ahead of a scorching Friday, then storm chances rise

Washington Post7 hours ago
Welcome to cwg.live, updated around-the-clock by Capital Weather Gang meteorologists.
Happening now: A bit more humid this morning than yesterday. Not too uncomfortable yet, though, as morning 70s rise well into the 80s this afternoon with mostly sunny skies.
What's next? Another notch warmer tomorrow, then superhot Friday when the heat index could reach near 105. Rather hot and humid this weekend as storms chances climb.
Today's daily digit — 8/10: A little warmer and a little more humid. Still a lot to like with highs below 90 degrees in most spots and no storms. | 🤚 Your call?
The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale.
Forecast in detail
Today (Wednesday): No shower or storm worries again today as we climb toward a touch warmer highs in the mid- to upper 80s under mostly sunny skies. Humidity is up a notch as well, into the moderate range with dew points in the mid-60s. Winds are light from the southeast around 5 to 10 mph. Confidence: High
Tonight: Mostly clear and somewhat muggy, but still not too bad, with lows in the upper 60s to low 70s. Confidence: High
Tomorrow (Thursday): Plenty of sun and another step warmer, as light winds from the south help bump afternoon highs into the upper 80s and low 90s. Humidity climbs into the moderate to high range but shower and storms chances remain slim to none. Confidence: High
Tomorrow night: Still mostly clear but the mugginess is back almost at full force with lows in the low to mid-70s. Confidence: High
A look ahead
The heat is on Friday with highs at least in the mid-90s, possibly near 100 in some spots. With high humidity, heat indexes could reach near 105. Storm chances could return Friday afternoon into evening, although as of now it looks like just an isolated storm at most. Muggy Friday night lows in the 70s. Confidence: Medium
Heat sticks around for the weekend with highs aiming for the mid-90s Saturday and low to mid-90s Sunday. High humidity should push the heat index to near or above 100 both days. Storm chances ramp higher with scattered late-day storms possible both days. Some could be strong to severe. Confidence: Medium
Next week probably starts with more 90s and storm chances on Monday and Tuesday, eventually trending a bit cooler mid- to late week.

Cities that will be hottest as nearly 100 million people are under alerts

One of the most significant heat waves of the summer continues to build across the eastern half of the country on Wednesday. Major to extreme heat risk — the highest threat categories — target areas along the Mississippi River, from the Upper Midwest to the Gulf Coast, and are set to shift eastward in the days ahead. Some of the worst mix of heat and humidity will occur Wednesday as the heat wave's footprint grows and intensifies. Heat alerts are in place for just shy of 100 million people two dozen state. Temperatures in the Midwest region will soar into the 90, and it will feel 10 degrees hotter than that. The highest risk alerts — extreme heat warnings — encompass much of the mid- and lower Mississippi Valley region, including St. Louis, Memphis, Little Rock and New Orleans. There, roughly 12 million people will face heat index values of 110 degrees to perhaps as high as 120 degrees during a brutal afternoon. While unusually high temperatures will cover more areas through the rest of the week, this region is likely to see the most persistent and longest-lasting effects from the current event. 'There is high confidence that heat will reach levels that would affect anyone without sufficient cooling and/or adequate hydration,' the National Weather Services warned. 'Long duration heat waves that last multiple days in a row, with little to no overnight relief and high humidity levels, often pose the greatest danger.' Additional alerts are popping up in the Northeast, including in and around Boston. Temperatures there and into the Mid-Atlantic are expected to rise well into the 90s to potentially around 100 degrees late in the workweek. Below are some of the cities most at risk for dangerous conditions Wednesday and into Thursday. An extreme heat warning is in place for Baton Rouge through Wednesday. High temperatures near 100 degrees will have a heat index approaching 110. It should be about five degrees less intense roasting on Thursday. Sultry conditions grip the Big Easy amid an extreme heat warning Wednesday for high temperatures around 95 degrees and very high humidity causing feels-like values around 110. A few storms could break the heat late day, and it should be a touch less intense Thursday. There's no relief even right on the coast. Extreme heat warnings are in place, with high temperatures in the mid-90s and a toasty Gulf bubbling moisture into the air. Heat indexes will be around 110 degrees in the afternoon. More clouds and rain by Thursday should help moderate temperatures. The city should hit the mid-90s through at least Thursday, with heat indexes forecast to rise between 105 and 110 degrees on Wednesday. There's only a slight chance of a storm and little change in the forecast beyond Thursday. Also under extreme heat warning Wednesday, Memphis is forecast to see heat indexes around 110 degrees in the afternoon. Actual temperatures will end up right around 100, with similar expected Thursday and Friday. An extreme heat warning is in place for the capital of Arkansas, where highs are forecast to rise above 100 degrees on Wednesday and Thursday. Heat indexes are likely to reach 110 to 115 across the region. Extreme heat warnings are in place through Thursday. Wednesday's forecast is for a high of 96 degrees with peak heat index of 116. Temperatures will probably rise near 100 again on Thursday. Heat advisories are in place for the Windy City and surrounding region through Thursday. Highs in the low and mid-90s Wednesday will rise several degrees further on Thursday, with heat index values within a few degrees of 105 expected. Overnight lows will only fall to near record values in the upper 70s. A home of corn sweat, unbearable humidity makes highs in the low 90s feel more like 105 degrees. Late-day storms are likely, and 80s should replace 90s on Thursday. A high right around 90 degrees Wednesday will lead make it feel more like 100 degrees in the afternoon. The air mass will moderate somewhat into Thursday with a cool front passing the region and delivering rainfall late Wednesday into early Thursday.

Scattered showers, thunderstorms roll in across South Florida

South Florida is in for another round of wet weather on Wednesday. Scattered showers and storms will move across parts of South Florida with the potential for some heavy downpours and localized flooding. The Weather Prediction Center has placed Broward, and most of Miami-Dade, under a marginal (level 1) risk of flash flooding. The National Weather Service said Miami-Dade is under a flood advisory until 11:45 a.m. It said additional rainfall amounts of 1 - 3 inches are expected which could lead to minor flooding in low-lying and poor drainage areas. Areas impacted include Miami, Hialeah, Coral Gables, South Miami, Kendall, Doral, Pinecrest, Miami Springs, Sweetwater, West Miami, Medley, Westchester, Olympia Heights, Fountainbleau, University Park, University Of Miami and Miami International Airport. Highs will climb to around 90 degrees in the afternoon, however, when the humidity is factored in, it will feel like the upper 90s and low 100s in some areas. The upper-level area of low pressure that has brought the moisture and rain over the last few days will keep the chance of rain higher on Wednesday. Some lingering moisture on Thursday will lead to some passing showers and storms. However, it will be a transitional day as Saharan dust begins to move in. The Saharan dust and drier air will continue to move in on Friday and through the weekend, lowering the chance of rain. As the rain moves out, the sizzling heat returns. Highs will soar to the low 90s and it will feel like the triple-digits when you factor in the humidity on Saturday and Sunday. The National Hurricane Center is giving the trough of low pressure near the southeastern U.S. coast a 10% chance of development as it moves west-southwestward the next few days. Regardless of development, this system will bring heavy rain to Florida and then the northern Gulf coast through this weekend.

Heat advisory for Chicago area starts today; humidity adds to dangerous temperatures

A Heat Advisory is in effect for the entire Chicago area Wednesday, lasting through Thursday night, as high temps and humidity combine to make a heat index well into the triple digits. While actual temperatures today and tomorrow are in the mid- to high-90s, the humidity will make it feel like anywhere from 105 to 115 degrees. The humidity is driven at least in part by what's commonly called "corn sweat," an agricultural phenomenon formally called transpiration in which plants release water from their leaves to help them move water. Corn, soybeans, alfalfa and sugarcane are crops with high levels of transpiration, which releases more moisture into the air; Illinois leads the country in corn growth with about 11 million acres planted. The Heat Advisory was issued for Boone, Cook, DeKalb, DuPage, Lake, Will, Kane, Kankakee, LaSalle, Kendall and McHenry counties in Illinois and Benton, Jasper, Lake, Newton and Porter counties in Indiana until 10 p.m. Thursday night. In such extreme heat, anyone going outside should make sure they drink water before leaving the house and continue to drink water as often as possible while outside. Doctors recommend drinking water every 20 minutes if possible. It's also advisable to wear light-colored clothing which reflects the sun instead of absorbing heat. Cooling centers are open in Chicago and Cook County to help people who don't have air conditioning or access to reliable air conditioning, and officials are asking residents to make sure they check on their elderly or health compromised neighbors to ensure they're staying safe in the dangerous temperatures. All Chicago public pools are also open, most from 11 a.m. to 7 p.m., as are city splashpads and water features in parks. Still, in such extreme heat and humidity, experts recommend staying inside as much as possible, and seeking shade when you do leave the house. Heat exhaustion and heatstroke are major risks during these weather events, especially with high humidity. It is easy to become overheated and dehydrated in high temperatures, so it is essential to make sure you are drinking enough water. Heat exhaustion is milder than heat stroke. Heatstroke is a serious illness that happens when the body begins to lose its ability to regulate its own temperature and functions, and can result in permanent disability or death if not treated as quickly as possible. Heat exhaustion symptoms include headache, nausea, dizziness, weakness, irritability, thirst, heavy sweating, high body temperature and decreased urine output. If you or someone you know is experiencing heat exhaustion move into a cool indoor space or shade immediately, give them liquids to drink, remove unnecessary clothing including shoes and socks, used cold water or a cold compress to cool the person down on their head, face and neck, and frequently sip cold water. The CDC also encourages calling 911 or taking the person to an urgent care clinic or the emergency room for treatment. Heatstroke symptoms include confusion, altered mental status, slurred speech, hot and dry skin or profuse sweating, very high body temperature, loss of consciousness, and very high body temperature. If treatment is delayed, it can quickly become fatal, the CDC says. If you are with someone experiencing heat stroke, call 911 immediately and stay with that person until help arrives. Move them into a shaded, cool area and remove their outer clothing then work to cool them down as quickly as you can with cold water or an ice bath if possible. Wet the skin or place cold, wet clothes on the skin, or soak their clothing with cold water. You should also circulate the air around them by fanning to help cool them off. The CDC also recommends placing cold wet cloth or ice on the head, neck, armpits and groin to help cool them faster.
