As of 4:45 PM, we have CANCELLED the watch for Allegheny, Westmoreland, and Washington Counties, (as well as Indiana and Armstrong earlier). One warning is in effect near the Ohio River in Monroe/Wetzel. We will continue to monitor for the need for additional adjustments.

A special weather statement has been issued for New Martinsville WV, Sardis OH and Pine Grove WV until 5:30 PM EDT

Outflow from the earlier storms has contaminated the environment over most of the forecast area, and the threat of severe storms is waning. After discussion with neighboring offices and SPC, we have CANCELLED the remainder of the Severe Thunderstorm Watch in our forecast area.

Flash Flood Warning including Bethel Park PA, West Mifflin PA and Baldwin PA until 10:30 PM EDT

7:55 PM | Some areas have received multiple rounds of heavy rain today. Scattered non-severe storms continue this evening & may cause localized flash flooding. Flash Flood Warning is in effect for portions of Allegheny, Washington, & Westmoreland counties until 10 PM.

Flooding is occurring in the South Park Township area (confirmed by local 911 Call Center) in Allegheny County. Please use caution whilst driving this evening.

Here is the outlook through the upcoming week.

Say goodbye to meteorological summer! The most notable information from the August and summer climate summaries was the paucity of rain; Zanesville set a new rainfall minimum record for August and New Philadelphia did as well for the summer (June-August) period. #PAwx #OHwx #WVwx

The area will have one last shot at a shower this evening as a secondary cold front moves through. Most of you won't see any rain, but there are a few isolated showers crossing the region. Dry, cooler, and sunny weather is then expected for most of the week.

A touch of fall to begin the week, then a return to more normal temps by Wed and Thu. A cool NW flow will setup over the area today as high pressure moves across the Great Lakes. This will mean cool temps, comfortable conditions, and lots of sun. Enjoy your Labor Day holiday.

Like cool temps? Then you'll like this 6-10 day outlook from the Climate Prediction Center! Below-normal temps are the most likely outcome from September 7th through the 11th, with a slight lean towards above-normal rainfall.

Look at the high temperatures this afternoon 😍 #FallWeather

A little bit of steam fog can be seen forming along the rivers of northwest PA early this morning where temps have dropped into the low/mid 40s. Another beautiful day is in store with highs in the 70s and plenty of sunshine. #pawx #ohwx #wvwx

Dry through Thursday, with the next rain chance by the end of the week. Here is the probability of >0.25" of rain for the 48 hour period ending at 8 AM Sunday. Chances are a bit better north of Pittsburgh at this time, and a little less where the current drought is more severe.

Here's some satellite imagery from this morning. You can clearly see the river valley fog in central PA diminishing, while upper level smoke out of Canada moves in out of the northwest.

The gradual warming trend continues through Friday with shower chances returning Friday night and Saturday morning as a cold front passes. Dry and cooler weather then starts the new week.

Another beautiful day on tap for Thursday though you may notice a bit of a milky sky with wildfire smoke hanging around high in the atmosphere. Rain chances return late Friday with a cold front passage that will drop temperatures to more of an early October feel for the weekend.

Rain returns later tomorrow and into Saturday, but will be followed another stretch of dry conditions the second half of the weekend and next week.

A cold front will bring scattered showers and thunderstorms to the area this evening. A few could reach severe levels west of Pittsburgh, but that is *highly* dependent on if the cloud coverage holds off long enough. Temperatures will fall to below average for the weekend.
