Flash flooding will be possible today in the Pittsburgh area
Flash flooding will be possible today for parts of the Pittsburgh area. Any Alert Days Ahead? Today Will Be a First Alert Weather Day beginning at Noon due to flash flooding risk. No other days reach into the possible range just yet but plenty more rainy days are incoming with high humidity levels. This is just a fancy way of saying that I do believe we will see more flash flood weather days over the next week. Aware: Yesterday's high of 90° was the 6th 90 degree day of the year. Today is going to be a First Alert Weather Day beginning at noon due to a flash flood risk. There is ample moisture to work with, and a cold front kicking through and stalling will bring storm chances our way. Since the front is expected to align west to east, multiple fast-moving storms are expected to continue to flow over the same areas, raising the potential for flash flooding. Model data indicates ranges from anywhere from half an inch to more than an inch and a half. When talking about flash flooding, I have always bumped up the top model numbers by 150%. This means that some isolated spots could see upwards of 2.5"-3" of rain. This means low-lying areas, especially, may be impacted by quickly rising water. Flash flooding is always a tough event to forecast because it is so limited in scope, but it has such a high impact on those it does actually impact. KDKA Weather Center The highest rain chance will come from 2 p.m. to 7 p.m. I do expect to see rain falling outside this window, but flash flooding and severe weather chances will be highest during this time. On top of flash flooding, we also have the chance for windstorms to fly through. Severe thunderstorms will be possible due to these fast-moving storms with wind speeds potentially topping 58mph this afternoon. It appears the tornado threat will be low today, but I want to just add that we can't completely rule out tornado chances. Looking ahead, I have rain chances in place on six of the next seven days. Sunday does stick out as another day where a First Alert may be needed. Humidity levels will be on the high side, so that means downpours will continue to be possible on any day. Let's quickly get to your forecast, with highs today hitting the upper 80s. Highs will come down to the mid to low 80s on both Tuesday and Wednesday. KDKA Weather Center Each day will see morning lows up near 70°. Highs for the rest of the week will be in the mid to upper 80s.

Fireworks smoke and haze linger on Saturday morning in Pittsburgh as hot weather looms
Lingering fireworks smoke from Friday night has led to unhealthy air quality across most of Western Pennsylvania and the Ohio Valley/Great Lakes states early Saturday morning. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos This smoke is trapped near the surface due to light winds and a temperature inversion, which prevents air near the surface from rising and mixing vertically. Air quality in western Pennsylvania early on Saturday morning KDKA Weather Center This smoke will continue to be an issue through mid-morning until the low levels heat up enough to mix some of it out, with lingering hazy skies expected the rest of the day. As high pressure moves east and winds shift to the southwest, we expect a warmer air mass to move in from the southwest today as well. Our region will be fixated within a ridge of high pressure and a potential tropical system moving ashore to the Carolinas Saturday into Sunday, which will amplify sinking air aloft, leaving us with mostly sunny to partly cloudy skies and overall dry conditions. Saturday high temperatures KDKA Weather Center Highs on Saturday and Sunday are expected to be in the upper 80s to near 90, with the most likely days to reach 90°F or higher being Sunday and Monday. Dew points will be elevated during the early morning hours, but drop in the afternoon thanks to drier air mixing aloft, which should help prevent heat indices from reaching hazardous levels. 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. Sunday's high temperatures KDKA Weather Center One more hot afternoon is expected Monday ahead of a weak trough moving in from the northwest by early evening. Some isolated to widely scattered storms appear likely to develop along this system's advancing front, but coverage doesn't look too great right now, mainly due to weak amounts of lift. Gusty outflow winds and locally heavy rain will be possible with any storm, but widespread severe weather is not expected. The system that brings the rain chance Monday evening should dissipate just south of our area Tuesday and Wednesday, with a remnant storm chance during peak heating both days. Rain chances over the next week KDKA Weather Center Another system with higher levels of moisture and better rain chances may approach by the end of next week. 7-day forecast: July 5, 2025 KDKA Weather Center Stay up to date with the KDKA Mobile App – which you can download here!

Pittsburgh has noticeably more comfortable weather on Wednesday as humidity dips
I'll let the weather do the talking today and won't take up too much of your time talking about the picture-perfect weather. I will quickly tell you about what has changed and how long it is going to take. Deal? Deal. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos My advice for you is to get out and enjoy this weather through Saturday. Dew points will be in the moderate range, but are down from the string of high tropical air mass days we have seen recently. One of the best ways to measure humidity at the surface (where we are) is through the dew point. Dew points over the next few days KDKA Weather Center Dew points had been averaging around 70 degrees over the past 10 days. Today, they have dipped into the mid to low 60s across the region. The 5° difference will be noticeable for those stuck outside today. That means that even on a day like today, where I expect highs to hit the mid-80s, you'll be a lot less sticky and sweaty if stuck outside. Conditions in the Pittsburgh area on Wednesday, July 2, 2025 KDKA Weather Center Speaking of the weather, highs today, Thursday & Friday will hit the mid-80s with humidity levels in the moderate to even low range. July 4th is looking like the pick of the week with humidity levels dipping down to near 60°. Highs will still hit the mid-80s. Temperatures do warm up this weekend with highs near 90 on both Saturday and Sunday. Humidity levels will climb up to the 'high humidity' level on Sunday, with those conditions sticking around through next Tuesday. 7-day forecast: July 2, 2025 KDKA Weather Center Stay up to date with the KDKA Mobile App – which you can download here!

Strong storms and flooding will be possible today in the Pittsburgh area
Strong storms and flooding are possible today for parts of the Pittsburgh area. Any Alert Days Ahead? Today is a First Alert Weather Day due to a flooding risk. Aware: 5.32" of rain has fallen in Pittsburgh this month, making it the wettest June since 2019. Did you enjoy the one-day break from the rain? Rain and storm chances are back today with downpours potentially leading to flash flooding. We have already seen plenty of rain this month, 5.32" of rain at the Pittsburgh airport. This is already the wettest June since 2019. If we see 0.35" of rain today or more, we will end the month as a top twenty wettest June on record for Pittsburgh. I have everyone seeing rain today, but most of your day will be dry. Most folks will see less than an hour total of rain. KDKA Weather Center Storms may be intense though, with rain rates of 1.5" to 2" possible with the most intense. This means it would only take thirty minutes to see more than an inch of rain. With how saturated the ground is already, intense downpours, and topography that is conducive to flash flooding, the risk for flooding is marginal to slight. As always, if you see water on a road, just find another route other issue today is that some of these storms will have a fast-moving forward speed. If wind speeds on the leading edge hit 58mph or higher, severe thunderstorm warnings will be issued. Oddly enough, the fast-moving storms should help to limit flooding. If storms were expected to move through slower than forecast, we would see our flooding risk be much it comes to the forecast, highs today should hit the mid-80s with temperatures near the high of 84 degrees at noon. Morning temperatures, for the 9th day in a row will fail to dip below 70 degrees. Winds will be light and out of the south. It'll be humid with dew points in the upper 60s for the day. Tuesday highs will also be in the mid to low 80s with high humidity levels remaining in place before Tuesday's cool front passes. Tuesday highs will also be in the mid to low 80s. While it doesn't look like the chance will be as high, flooding and strong winds will be possible again on Tuesday. The rest of the work week should see more comfy weather, even as the high temperatures don't change too much. Humidity levels will sink though, and you'll notice the difference. KDKA Weather Center The 4th of July is looking comfy with just an isolated rain chance at this time. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos

Pittsburgh in for a calm, but humid weather day on Sunday
We finally get a break from the rain and storms today. You'd think we'd also get a break from humidity and heat as well but that isn't going to be the case. Today will be hotter than yesterday with highs near 88 degrees. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos Yesterday's high was 86°. Humidity levels will also remain in the high range with dewpoints in the upper 60s all day long. Temperatures do finally dip below 70 degrees this morning; the first time we've done that since last Saturday. Conditions in Pittsburgh on Sunday, June 29, 2025 KDKA Weather Center As we head through the day, there are a couple of things to talk about. First off, if you're reading this before 10 a.m., there is likely some fairly dense fog out there in spots, with the fog being denser to the north of Pittsburgh, where skies were clear all night. Places south of I-70 probably won't see too much fog due to cloudy skies not allowing sufficient cooling. The other issue is the potential for high ozone levels making their way to the surface. Ozone develops due to a chemical process in the mid-levels due to greenhouse gases and energy from the sun's rays. Most development happens in the afternoon. At least for now, readings remain low, but that may change this afternoon. Estimates from Saturday's rainfall KDKA Weather Center We will monitor things there, but at least this morning, I am not seeing anything too concerning. Looking ahead, there seems to be some uncertainty about Monday when it comes to rain and storm chances. As of this morning, the Storm Prediction Center has us painted in as a marginal level one out of five risk of severe weather on Monday. They do not have us having a severe weather risk on Tuesday. Potential for severe weather on Tuesday, July 1, 2025 KDKA Weather Center I think the data this morning is heavily leaning towards the higher risk of severe weather happening on Tuesday. There is a chance for strong storms as a warm front lifts through late Monday into Tuesday, but this storm chance happens right at midnight. Most storm activity should come on Tuesday. Similar to what we have seen over the past couple of days, strong winds and flooding due to downpours are the main concern. Tuesday is when relief really arrives as a cold front sweeps through, taking the excess moisture with it. Temperatures at that time will return to near normal for this time of the year, with highs hitting the mid-80s for the rest of the week, with morning lows in the mid to low 60s. 7-day forecast: June 29, 2025 KDKA Weather Center Stay up to date with the KDKA Mobile App – which you can download here!
