Today is starting murky in and around Pittsburgh, with fog already slicing visibility across parts of the region and slowing some early drives. Temperatures sit in the low to mid 70s with sticky humidity, and river valleys plus other low-lying neighborhoods are dealing with the thickest soup. If you are heading out before mid-morning, plan on extra time before conditions gradually improve.
Dense Fog Advisory And Morning Conditions
According to NWS Pittsburgh, a Dense Fog Advisory runs through 9 a.m. EDT Sunday, and forecasters are urging motorists to take caution and use low beam headlights where visibility drops. The advisory calls out the I-80 corridor and neighboring valleys as hot spots for the worst conditions and notes that visibility can change in a hurry over short stretches of road. If you have to drive, slow down and leave more space than usual between you and the car ahead.
Afternoon Storm Window
Showers and thunderstorms are on the table Sunday, with the main action expected roughly between 8 a.m. and mid-afternoon, then scattered storms lingering into the evening. Highs should land near 85 to 87 degrees. Any stronger cells could bring brief heavy downpours and lightning, with generally light winds that may gust when a storm rolls through. If your plans are outdoors, you might want a backup indoor option or an earlier time slot, and it would not hurt to keep a weather app or radar close by. A similar setup is expected Monday, with another round of afternoon showers and thunderstorms in the cards.
Flooding And Wind Concerns
Forecasters note a localized flash-flooding risk where storms train over the same spots or briefly stall. A widespread severe weather outbreak is not anticipated, but a few storms could still kick out brief damaging winds or small hail. Most places are looking at rainfall totals of only a few tenths of an inch, yet heavier pockets could trigger quick flooding on low-lying streets and in poor-drainage areas. For the more technical breakdown of these risks, check the NWS discussion.
What To Do Now
In the fog, ease off the gas, use low beams, and avoid sudden moves. Never try to drive through standing water; as the saying goes, turn around, don't drown. If you hear thunder, head indoors and hold off on open-air activities until storms pass. Keep kids and pets inside during heavy downpours. This page will be updated if warnings change, and you should keep an eye on NWS products and local alerts before heading out this afternoon.
