Heavy rain and dense fog socked in the Pittsburgh area overnight, with visibility at Allegheny County Airport dropping to roughly 1.5 miles and temperatures hovering near 63°F early Monday, June 15, 2026. The murk will not last long, though, as skies are expected to clear through the morning, setting up a mostly sunny day with a high near 71°F.
Morning Fog, Improving Skies
Low clouds and mist should thin by mid- to late morning as daytime heating mixes the boundary layer and helps scrub out the fog. Northwest winds will be on the light to moderate side, generally 5–12 mph, nudging afternoon temperatures into the upper 60s and close to that 71°F mark.
Midweek Storm Watch
After today, the weather stays quiet through Tuesday, with highs climbing into the upper 70s, before the pattern turns unsettled by midweek. Late Wednesday night into Thursday, June 18, the National Weather Service is monitoring the potential for hazardous weather, including damaging wind gusts, a tornado risk, and heavy rainfall that could trigger localized flooding. Keep an eye on watches and updated forecasts as the week moves along. For details, see the National Weather Service.
Plan Ahead
Once the fog burns off, the morning commute should be mostly trouble-free, but roads that stayed wet overnight could still be slick, so allow a little extra time for early travel. If you have outdoor plans for Thursday, June 18, or Juneteenth events on Friday, June 19, it is smart to have an indoor backup ready and to follow local forecasts, and see our storms slam tonight coverage for more context on this week’s shifting pattern.
