KDKA-TV Weekend Forecast (5/9)

Added: 2026-05-10

[00:00:00]It turned out to be a great day for it, because it started off chilly and rainy.

[00:00:04]It's actually warmed up quite nicely, and I'm hoping that will hold though for Mother's Day tomorrow, right? There may be a few showers tomorrow, but as we've been talking about all week, we're not expecting a washout of a weekend, and we had that break in the rain earlier this afternoon. Won't last much longer though, because there are some thunderstorms to the north and west.

[00:00:21]That's why you see the coverage of rainfall start to go up here later this evening, especially after 7:00 to 8:00 p.m. We'll see that jump up to around 60%. Temperatures overnight drop down into the low to mid-50s, and then there are your showers that come in early tomorrow morning after sunrise and into the midday time frame. The thunderstorms we are watching right now are moving across Lake Erie. They are moving fairly quickly off to the east at around 45 to 50 mph, so we'll kind of we'll put on a distance track tool here to show how fast these are moving and where these are generally headed off to the east.

[00:00:54]So, that may place it in the northwestern portions of Mercer County as we get closer to around 7:00 to 8:00 p.m., 7:45 to 8:00 p.m. Northern portions of Venango County as well. And you can see there are a couple of severe thunderstorm warnings in effect for the Cleveland area, but as these cells work their way to the south and east, they are going to weaken with time. A severe thunderstorm watch is just outside our coverage area, doesn't include any of our counties, but if you're headed up toward Lake Erie, that will be in effect through 11:00 p.m., but the general trend with that line of thunderstorms will be weakening, as you can see the amount of storm fuel ahead of the line really tapers off, especially from Pittsburgh south in the northern West Virginia. So, we can't rule out one or two severe thunderstorm warnings this evening if you're up to the north and west, but as you can see, high-resolution modeling doing a pretty good job showing that as it enters this less favorable environment, it will weaken with time. But as we get closer to 8:00 p.m., areas from Newcastle up toward Butler, Franklin, Clarion getting in on these weakening thunderstorms.

[00:01:50]They'll move into the Pittsburgh area as we get closer to 9:00 to 11:00 p.m., and And how that line really starts to fall apart as it heads to the south toward the I-70 corridor. The cold front driving this line of thunderstorms will move through tomorrow morning and then we expect mostly cloudy skies and some scattered areas of showers as we head through the morning and midday time frame, especially from 8:00 through roughly 2:00 p.m. Those will start to clear up late tomorrow evening and it should be a pleasant Sunday evening and then we go into some cooler air for early next week. Our morning temperatures Monday down into the lower 40s. We only recover into the mid upper 50s Monday afternoon and evening with partly cloudy skies. Then check out where we end up for Tuesday morning, down into the lower to middle 30s. There is the potential for frost and even a light freeze for some of our northern and northeast counties. So we want to give you a first alert for that. We may see some frost advisories and freeze warnings issued. Now, once this cold air mass moves out, we don't have much time to recover, but that will give us another chance for more showers and storms as this next disturbance comes in from the west. That will arrive on Wednesday and with the track of this low pressure with this next system, it may move off to the north just to give us enough moisture and instability for an isolated strong storm Wednesday. So we'll keep an eye on that for Wednesday.

[00:03:06]Cooler with lingering showers on Thursday and then we'll start to finally see temperatures warm up by next weekend.
