Today will be another hot one with southwest winds aiding our warmup with highs reaching the lower 90s.
High temperatures on July 6, 2025

Our region will be fixated within a flattening ridge of high pressure and Tropical Storm Chantal moving ashore to the Carolinas, which will amplify sinking air aloft, leaving us with mostly sunny to partly cloudy skies and overall dry conditions.
Despite air temperatures reaching the low 90s today, dew points holding steady and relative humidity dropping as temperatures heat up should keep heat index values out of the danger zone, largely in the mid to upper 90s. Individuals should still stay well hydrated while being outdoors, and those sensitive to the heat should take frequent breaks or avoid being outside during the hottest part of the day.
One more hot afternoon is expected Monday ahead of a trough moving in from the northwest by early evening. This trough will be forcing a decaying cold front in our direction, which will lead to scattered showers and storms developing along and ahead of the boundary.
High temperatuers and rain chances in the region on Monday

Expect development to occur by 1-2 p.m. in our northwest Pennsylvania counties before activity progresses south and east through the mid-late afternoon and early evening. While widespread severe weather is not expected, storms will be capable of producing microbursts with localized wind gusts up to 60mph, sub-severe or small hail, and very heavy rain. Moisture levels in the atmosphere are projected to be on the upper end to near daily record max levels by early evening, which will support a heavy rain threat with storms. Isolated 1-2" amounts are possible, which could cause flash flooding.
By Monday night into Tuesday, this cold front should move into the Laurel Highlands/Ridges and begin to fall apart over this area by Tuesday morning. The remnant boundary will likely induce some showers and storms Tuesday afternoon and evening, especially from Pittsburgh and points southeast.
Generally, dry conditions are likely from Tuesday evening through Wednesday afternoon, but our next system will approach by Wednesday evening with a low chance of storms.

More scattered storms are expected Wednesday night and Thursday as a slow-moving trough moves across our region. We will likely keep an unsettled pattern going into the end of the week with daily low afternoon storm chances through Saturday, but not all locations will see rain every day.
Rain chances over the next week

Temperatures will largely remain above normal with highs in the mid to upper 80s and lows in the mid to upper 60s.

Why Forecasting Thunderstorms Is Still So Hard
Thunderstorms can develop suddenly, transforming calm skies into scenes of heavy rain, fierce winds and dangerous lightning. And while the United States is no stranger to this weather phenomena, predicting when and where a thunderstorm will strike remains one of the most difficult challenges in meteorology, despite major advances in forecasting technology. Unlike larger weather systems, such as hurricanes or winter storms, which can be tracked over hundreds of miles and several days, thunderstorms tend to be hyperlocal and short-lived. Bill Bunting, deputy director at the federal Storm Prediction Center, said their unpredictability stems from their complexity and size. Forecasters often know up to a week in advance if conditions are likely to be favorable for thunderstorms, but their ability to pinpoint exactly where and when those thunderstorms kick off is much more limited. In Texas, they knew July 4 could feature severe thunderstorms, but it wasn't until just a few hours before heavy rain began to inundate the area around the Guadalupe River that their exact effects became clear. 'Thunderstorms are among the smallest and shortest-lived forms of hazardous weather in the U.S.,' Mr. Bunting said. 'They're typically five to 15 miles in diameter and last 30 minutes to a few hours.' Thunderstorms can occur nationwide, and at any time, 'day or night, throughout the entire year,' the National Weather Service says, but they are most common in the late afternoon and evening during the warm months. To understand the difficulty of forecasting thunderstorms, it helps to understand the different types, as well as how they form. Want all of The Times? Subscribe.

Reservoir to shut to public during weekend heatwave
Members of the public will be barred from a major reservoir this weekend to prevent them jumping into the water during the forecast heatwave. Access to the permissive path at Cheddar Reservoir in Somerset will be suspended from sunset on Thursday until Monday morning. Bristol Water, which operates the site, said the decision was made as part of its routine water safety practice during extreme heat. The company apologised to visitors, but said it wanted to avoid putting extra pressure on the emergency services. More news stories for Somerset Listen to the latest news for Somerset Reservoirs can be dangerous due to currents caused by pumping machinery, hidden underwater structures and their depth. Their steep sides often make it difficult for swimmers to get out. "With the extreme heat, and very little shade around the reservoir's permissive path, we want everyone to stay safe," Bristol Water said. "We know the water can look very tempting on hot days, but it can be extremely dangerous and we don't want any extra pressure on the emergency services on what will already be a very busy few days for them."

Umbrellas Optional? East Asia's Monsoon Rains Are No Longer a Sure Thing
South Korea's rainy season is historically several summer weeks when rain can fall in sheets at a moment's notice. But these days, Choi Moon-hee doesn't bother carrying an umbrella around Seoul anymore, even during the official monsoon season. On Tuesday evening, she lost her bet, getting caught in a shower after days without rain. It was the first downpour she had experienced since forecasters declared the start of the monsoon two weeks ago. 'In the past, if it started raining, it would last for about a half-month, and we'd use our umbrellas often,' said Ms. Choi, 43, while taking cover under the awning of a building. 'Nowadays, it often doesn't rain even when the forecast says it will.' In the south of the country, forecasters already declared the rainy season to be over last week. In western Japan, it was declared over in late June, the earliest point since records began. East Asia's rainy season has traditionally run from the middle of June into July, when a stationary weather front brings prolonged rainfall to the region. But the annual rains have become less predictable since the late 1990s, and scientists say that climate change is a major factor in that shift. Climate change, which has worsened extreme weather around the world, has also made the monsoon season more inconsistent in India and China, catching billions of people off guard with floods and droughts.
