Climate change is likely intensifying the heat wave scorching the UK, increasing temperatures by as much as 4C (7.2F), according to new research. High pressure over the UK, along with a stream of air that is rapidly warming as it descends from over Greenland, will bring highs of 33C to London on Saturday, with 34C for parts of eastern England, Met Office forecasts show.

Scorching Edinburgh heatwave set to be disrupted by weekend thunderstorm
Edinburgh locals have dusted off the paddling pools and erected the pagodas as temperatures as high as 27C hit the capital. Both the Met office and BBC forecasters have warned the UK will move into heatwave territory with temperatures climbing to 34C in the south of England and reaching the lofty 20s in Scotland. Residents and visitors of Edinburgh have been cautioned to expect a high pollen count so it may be worthwhile digging out the allergy tablets and sprays to keep those sinuses in check.

Pleasant weather returns to Pittsburgh on Friday, but a heat wave looms
Humidity breaks today, even as high temperatures go up. Earlier this week, model data was showing today's high being cooler than yesterday's high. I didn't bite and kept today's temperature warmer than yesterday's, and it looks like a good call at this point. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos The one thing that will be noticeably lower than yesterday will be dew points and oppressive humidity. Dew points are all the way down in the upper 50s right now, and that's about where they will be all day today. Conditions in Pittsburgh today KDKA Weather Center This has allowed morning temperatures to dip to near 60 to start the day. There was some valley fog due to the cool temperatures and saturated ground this morning. The pleasant weather will continue into the afternoon with highs hitting the mid-80s. I have noon temperatures near 80 degrees. Winds will be light, coming in out of the west at around 5mph. Expect lots of sunshine today, but a pesky shower or storm chance will persist this afternoon. I think almost everyone is dry, with the best chance for seeing a brief storm happening north of Cranberry and after 3 this afternoon. Saturday will be a transition day with us starting off with pleasant conditions, but humidity will go up throughout the day. I have Saturday highs hitting 87°. Temperatures and heat index over the next six days KDKA Weather Center Our first potential heat wave of the year arrives on Sunday, with temperatures flirting with 90 degrees all the way through at least next Sunday. History tells us that we likely won't see eight straight days with highs in the 90s, but it will certainly be possible. At this point, it doesn't look like we get too close to an overall record high temperature day in Pittsburgh. Places in our area that will be under Excessive Heat Watch beginning on Sunday KDKA Weather Center We'd have to hit 95° in order to set a record (Monday, Thursday) next week, and I don't have us getting to 93°. We may hit what we call a record max-min. This would be the hottest low temperature. Right now I have us tying the max-min record of 74° on Tuesday. Right now is the time to prepare for the heat, including checking a/c units to make sure they're working properly. You can also clean fan blades. Eating cool foods can also help to cool your body's internal temperature. Finally, cold showers are one of the best ways to stay cool in your home, both before and after it. If you can't get relief while at your home, head to your local library. 7-day forecast: June 20, 2025 KDKA Weather Center Stay up to date with the KDKA Mobile App – which you can download here!
