CWG Live updates: Two days of broiling heat, then a retreat

Washington Post3 days ago
Welcome to cwg.live, updated around-the-clock by Capital Weather Gang meteorologists.
Happening now: Temperatures rise quickly this morning amid high humidity and partly to mostly sunny skies. Afternoon highs reach the mid- to upper 90s, and heat indexes top 100.
What's next? Tomorrow is the hottest day of the week, and some evening thunderstorms could pop up. Storms are more widespread on Thursday before a cooling trend heading into the weekend.
Today's daily digit — 2/10: The searing heat is almost the worst of the summer. What a bummer. | 🤚 Your call?
The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale.
Forecast in detail
Today (Tuesday): Heat builds quickly this morning with 80s moving into the 90s by midday. Into the afternoon, highs reach the mid- to upper 90s under partly to mostly sunny skies. Dew points in the 70s mean heat indexes reach 100 to 105. Be careful with outdoor activities and stay as hydrated as possible. Light breezes from the southwest at about 5 mph offer little relief on this not nice day. Confidence: High
Tonight: Partly cloudy, humid and quite uncomfortable as lows fall into the 70s. Areas near downtown could stall closer to 80. Light breezes from the south at about 5 mph. Confidence: High
Tomorrow (Wednesday): Our hottest day of the week sends highs into the upper 90s for most with partly to mostly sunny skies and high humidity. Heat indexes of 100 to 105 are again taxing for outdoor activities. A few scattered late-afternoon and evening thunderstorms are possible. Winds are from the southwest at about 5 mph. Confidence: Medium-High
Tomorrow night: A shower or thunderstorm is possible, but the main story is another very uncomfortable night with muggy 70s to near 80 for lows. Confidence: Medium-High
A look ahead
Thursday marks the start of the transition away from this very hot weather. Skies are partly to mostly cloudy with numerous showers and storms, especially in the afternoon and evening. It's still sticky with highs in the upper 80s and low 90s. Thursday night brings more scattered showers and storms as temperatures cool toward about 70 degrees by early Friday. Confidence: Medium
The first day of August on Friday sends the heat away, but clouds and scattered showers may linger, especially across the southern part of the area. Highs are in the much more comfortable upper 70s to low 80s. Friday night may still see a few clouds, but humidity is much lower as lows dip into the 60s. Confidence: Medium
The first weekend of August may be the nicest summer weekend we have seen in quite some time. Skies are mostly sunny both days and humidity levels are low. Saturday night should be mostly clear with lows in the 60s or even upper 50s in our cooler areas, as humidity stays suppressed. Confidence: Medium-High
The nicer weather continues early next week with low humidity and 80s for highs. But temperatures and humidity increase later in the week as highs near 90, and showers and storms also return to the forecast.

Nearly 2 dozen Michigan beaches have high bacteria counts. See the list of place to avoid

Nearly two dozen Michigan beaches are under bacteria advisories or are closed as Michiganders head into the Aug. 2-3 weekend. In a state to more than 1,000 beaches, state officials say 21 beaches in counties across Michigan aren't fit for swimming. As of Friday, Aug. 1, there are multiple Michigan beaches that are currently closed or under advisory due to high bacteria levels — likely from wildlife, according to the Michigan Department of Environment, Great Lakes and Energy, which provides that information via an online dashboard. Beaches with closures or advisories Beaches include: Campbell Lake near Robert Morris Park in Kalamazoo County Clinch Park in Grand Traverse County Dumont Lake County Park Beach in Allegan County East Jordan Tourist Park in Charlevoix County Elm Point Beach in Charlevoix County Emerald Lake (Lyster Rd) in Oakland County Four Mile Beach in Chippewa County Grove Street Beach in Oakland County Halls Lake at Isabella County Independence Lake County Park in Washtenaw County Lakeview Waterfront Park in Roscommon County Lakewood Farms (Sharon Street) in Oakland County Newburgh and Sumac Pointes (Hines Park) in Wayne County Philp County Park in Huron County Pontiac Lake in Oakland County Ramona Park in Kalamazoo County Seven Lakes State Park in Oakland County St. Clair Shores Memorial Park Beach in Macomb County Sylvan Lake in Oakland County West End Beach in Grand Traverse County Willow Street Beach in Keego Harbor County health departments routinely collect water samples for bacteria levels at beaches across the state to determine whether the water is safe for swimming, according to the EGLE. To be considered safe for swimming, the E. coli counts must be below 300 per 100 milliliters. Check the conditions of your local beach The EGLE map lists information for beaches in Michigan, including water quality sampling results and beach advisories and closures. The website also includes information on combined or sanitary sewer overflows, which lead to partially treated or untreated sewage being released into rivers and streams. Why do officials check for E. coli? Generally, coliforms are bacteria that are not harmful and are naturally present in the environment, according to the U.S. Environmental Protection Agency. They are used as an indicator that other, potentially harmful, fecal bacteria (indicated by the E. coli species) could be present. If any routine or repeat sample is total coliform positive or present, the system (i.e., the lab) must further analyze that sample to determine whether E. coli are present. E. coli is a more specific indicator of fecal contamination and is a potentially more harmful pathogen than other bacteria typically found in the coliform group. Consumption of or contact with water contaminated with feces of warm-blooded animals can cause a variety of illnesses, the U.S. Geological Survey said. Minor gastrointestinal discomfort is probably the most common symptom; however, pathogens that may cause only minor sickness in some people may cause serious conditions or death in others, especially in the very young, old, or those with weakened immune systems. What is swimmer's itch? Does E. coli cause it? Swimmer's itch is a skin rash caused by an allergic reaction to microscopic parasites that infect some birds and mammals, according to the Centers for Disease Control and Prevention. Swimmer's itch is often incorrectly attributed to E. coli exposure, according to the Clean Lakes Alliance. Symptoms can include: Tingling, burning or itching of the skin Small reddish pimples Small blisters What can I do about swimmer's itch? Swimmer's itch typically clears up on its own within a week. If the itching is severe, your health care provider may recommend prescription-strength lotions or creams, the Mayo Clinic said. Some home treatments may provide relief until it goes away: Apply a corticosteroid cream or an anti-itch lotion, such as those that contain calamine. Take an oral nonprescription antihistamine (Benadryl) or one with loratadine (Alavert, Claritin, others). Avoid scratching the rash. Cover affected areas with a clean, damp washcloth. Soak in a bath sprinkled with Epsom salts, baking soda or an oatmeal-based bath product (Aveeno, others). Make a paste of baking soda and water, and then apply it to the affected skin.

After a generally mild start to summer, August is bringing triple digit temperatures

After a month of relatively mild summer temperatures across much of Southern California, Mother Nature is turning up the heat next week. Temperatures this weekend will hover in the mid-80s in downtown Los Angeles, and the high 80s to mid-90s in the valleys and persist through at least Monday, according to the National Weather Service. The low clouds and morning fog that hang along the coast and burns off by the early afternoon is also expected to continue. But not for long. The mercury is forecast to rise on Tuesday, and by Wednesday it'll be extra toasty across much of Los Angeles County with temperatures soaring past 100 degrees in the valleys and the low 80s along the coast, said Mike Wofford, a meteorologist with the National Weather Service, in Oxnard. Read more: City by the Bay? More like City by the Brrr! San Francisco is having its coldest summer in decades "We're not looking at temperatures like we've seen in some previous summers, where we've gotten to 120 degrees, but it's certainly looking like 5 to 10 degrees above normal," Wofford said. Downtown Los Angeles could experience temperatures in the mid-90s by the middle of next week. Woodland Hills is forecast to get up to about 107 degrees and Burbank could get up to about 100 degrees, according to the weather service. Over the last few weeks a persistent low pressure system has been lingering in the Pacific Northwest and British Columbia which has kept temperatures cooler across much of California. But next week a high pressure system will expand from New Mexico and Arizona toward the west coast bringing a significant warm up. "We definitely had a pretty quiet July. We had some warm temperatures in June there for a bit, but July was pretty blah in terms of temperatures," Wofford said. Widespread strong winds are not expected to accompany next week's warm up, reducing the risk of serious fire weather conditions, Wofford said. But it's still early in the fire season, experts warn. With heat waves likely continuing through the rest of the summer, drying out brush, and later fall winds kicking up, it could make for dangerous conditions in the coming months. As temperatures rise, officials caution the public to stay hydrated, avoid strenuous outdoor activities and check on those who are vulnerable to heat-related illnesses. On Wednesday, a 21-year-old hiker collapsed from possible heat stroke while hiking on a trail near Lake Berryessa. Another six hikers were also suffering from heat related illness and had to be rescued, according to the Vacaville Fire District. "Take HEAT seriously," the fire district warned in a post on Instagram. "This could have been deadly." Sign up for Essential California for news, features and recommendations from the L.A.

Very hot and humid first weekend of August

South Florida is in for a very hot and humid first weekend of August. Highs will remain slightly above average in the low 90s, and it will feel like 105 to 110 degrees when the humidity is factored in. The National Weather Service may issue heat advisories this weekend if the heat indices meet the criteria of 105 degrees or higher for at least two hours. The chance of rain is 20% with the potential for a few showers and some storms, but the bulk of the wet weather will be across the interior and West Coast. Over the weekend, a frontal boundary over the southeastern U.S. will settle over northern Florida before stalling through early next week. This will result in increased mid and upper-level moisture across South Florida. The chance of rain will increase in the early to middle part of the week due to this moisture and several weak upper-level disturbances moving through.
