Do not let Sunday’s sunshine fool you. After a clear, calm start, Pittsburgh is in for a full sampler platter of March weather on March 15, 2026. Temperatures that climbed into the mid-40s this morning are headed for the upper 60s this afternoon, but that warmth comes with a catch: strengthening southeast winds, a windy and wet night, and a quick turn toward wintry weather late Monday.
Through the afternoon, southeast winds will ramp up to around 7-18 mph, with widespread gusts near 35-40 mph. The Laurel Highlands and other exposed ridges could see peak gusts of 45-50 mph. Wind Advisories are posted for parts of the highlands and some northern counties from 4 p.m. Sunday, March 15, 2026, through 8 a.m. Monday, March 16, 2026, and those kinds of gusts are more than enough to knock down tree branches and trigger scattered power outages. Full advisory details are available from the National Weather Service Pittsburgh.
Late-Night Line Of Storms, Then A Monday Cooldown
Late Sunday night into Monday, March 16, 2026, a strong cold front charges through the region. Expect rain and a line of showers or isolated thunderstorms that could produce damaging wind, with forecasters noting a marginal severe risk for parts of western Pennsylvania and northern West Virginia. By Monday evening, the rain should wind down, but temperatures will fall quickly as colder air pours in. That will flip lingering precipitation to a wintry mix and then to snow Monday night. Most neighborhoods are expected to see little or no accumulation, although an inch or two is possible north of I-80 and on the higher ridgelines. If you have outdoor plans Monday afternoon, it is a good idea to move them inside or at least build in extra travel time, since conditions can change in a hurry.
Getting Ready For The Wind And The Flip To Cold
Before the gusts really kick in, take a few minutes to tie down or bring in anything that can blow around, including patio furniture, tarps, and trash cans. Drivers should be ready for strong crosswinds on bridges and in open areas, especially if they are in a high-profile vehicle. If the wind knocks out power, you can track outages through the Duquesne Light map and report any downed lines directly to 911. Utility crews typically focus first on immediate safety issues, then work on broader restoration after wind events. Keep an eye on local forecasts through Monday morning in case the timing shifts or additional advisories are issued.
