CWG Live updates: Scorching today and storms likely late Thursday, then much cooler
Welcome to updated around-the-clock by Capital Weather Gang meteorologists. Happening now: Most of the region is under a heat advisory today from 11 a.m. to 8 p.m. as mostly sunny skies heat us into the mid- to upper 90s. Heat indexes rise to 100 to 105 this afternoon. What's next? Maybe an isolated shower or storm late this afternoon or evening. A little cooler Thursday with better storm chances, then cooling into the weekend, which looks delightful. Today's daily digit — 1/10: We've had worse humidity this summer, but not sure it really matters as the heat index is headed for a brutal 100 to 105 once again. #makeitstop | 🤚 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): The sun beats down as we head for highs in the mid- to upper 90s and heat indexes reaching 100 to 105. Limit outdoor time and stay hydrated. Can't rule out a few isolated late-afternoon showers or thunderstorms, especially west of D.C., although the odds at any given location are less than 20 percent. Confidence: Medium-High Tonight: Just that chance, still less than 20 percent at any given location, of an isolated evening shower or thunderstorm. Evening readings fall back into the 80s with overnight lows in the 70s under partly cloudy skies. Confidence: Medium-High Tomorrow (Thursday): Mostly sunny through the morning and perhaps into early afternoon before increasing clouds. Still humid with highs in the upper 80s to mid-90s. Scattered showers and thunderstorms become likely at some point during the midafternoon into evening as a cold front approaches, with a threat of damaging winds and flooding. Confidence: Medium Tomorrow night: Scattered showers and storms are likely during the evening. Some storms could bring damaging winds and flooding. Less intense showers and storms remain possible overnight with muggy lows in the 70s. Confidence: Medium A look ahead Mostly cloudy Friday with much cooler highs in the 70s. Isolated to scattered showers and a thundershower remain possible during the morning into the afternoon as plenty of moisture lingers in the atmosphere. But drier air arrives by evening, allowing Friday night lows to drop into the 60s. Confidence: Medium We can keep this short and sweet for the weekend and Monday. All three days should be partly to mostly sunny with pleasant highs near 80 to the low 80s and low humidity. (Dew points in the mid-50s to near 60.) Overnight lows around 60 to 65 are comfortable as well. Enjoy!

Confidence: Medium-High The National Weather Service has placed the area under a heat advisory from 11 a.m. to 8 p.m. Wednesday due to heat indexes that could reach 105 to 109. Actual temperatures should rise to the mid- and upper 90s most locations, which is a step up from Tuesday's readings. 'Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,' the Weather Service advised. It will be the sixth day of the current heat wave. Temperatures begin to trend downward starting Thursday. Here are some important heat safety tips … More heat safety infographics can be found here. The heat index, the 'feels-like' temperature, exceeded 100 degrees again in Washington on Tuesday, in a sort of demonstration that history does repeat itself, while also authorizing use of the expression déjà vu. The day's official high temperature, more precisely, the air temperature, rose to 94 degrees. That was a respectably warm figure, five degrees above the normal or average high in D.C. for July 29. But the heat index, possibly an even more meaningful figure for those spending summer in the capital, and a better indicator of the stresses of a summer day, exceeded 100 degrees. It resided at or above 100 degrees for five consecutive afternoon hours. And to underscore the repetitive and old-hat aspects of Tuesday's weather, it can be noted that the heat index had also exceeded 100 degrees on Monday. And it exceeded 100 on Sunday, too. This has been a steamy summer, a time of sweltering, sultry days, and Tuesday, particularly with its high heat index, seemed one more of them.

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

CWG Live updates: Uncomfortably hot and humid through midweek, relief by Friday
Welcome to updated around-the-clock by Capital Weather Gang meteorologists. Happening now: Partly to mostly sunny this morning with temperatures quickly climbing into the 80s. Muggy and hot this afternoon, with highs in the 90s. What's next? Staying hot and humid through Wednesday. A cold front brings likely showers and storms on Thursday before drier and cooler air moves in Friday through the weekend. Today's daily digit — 4/10: It's still like a steam bath out there but at least we should stay storm-free. | 🤚 Your call? The digit is a somewhat subjective rating of the day's weather, on a 0-to-10 scale. Forecast in detail Today (Monday): Partly sunny skies early become mostly sunny for a good part of the day. As the sun beats down, it's hot and also rather humid (dew points in the low 70s). Highs range from 90 to 95 but it feels like 100 or so. Light winds are from the north at around 5 to 10 mph. Confidence: High Tonight: A mostly clear and muggy late July night. Lows range from near 70 in our cooler spots to the mid-to upper 70s downtown. Calm winds. Confidence: High Tomorrow (Tuesday): Sunny and very hot. Highs range from 93 to 98 but feel like 100 to 105 with the humidity (dew points in the low 70s). There's little breeze to take an edge off the heat. Confidence: High Tomorrow night: Mostly clear to partly cloudy and warm. Lows range from the low 70s in our cooler areas to the upper 70s downtown. Very light breezes are from the south. Confidence: High A look ahead Wednesday is a lot like Monday and Tuesday: mostly sunny, hot and sticky. Highs reach the mid- to upper 90s but feel like 100 to 105. Toward the evening and overnight, a few storms could pop up, especially in our western areas. Lows are in the 70s. Confidence: Medium-High Thursday marks the transition between the hot, humid weather pattern of the week's first half and the cooler, drier pattern on the way. The cool front sweeping through sets off showers and storms, some of which could be heavy. Highs should still climb to 90 or so before clouds and storms move in. Showers and storms should gradually move off overnight, with lows in the mid-60s to near 70. Confidence: Medium The weather from Friday through the weekend looks fantastic. Humidity levels and temperatures drop and sunshine emerges. Clouds and humidity could linger during the first half of Friday before the sunny, dry weather takes over. Highs on Friday are in the upper 70s and low 80s. Sunshine should dominate both weekend days with highs again in the upper 70s and low 80s. At night, lows dip into the 60s although there could be some upper 50s in our cooler areas.
