Pittsburgh weather: Storms possible Tuesday

If we see rain Tuesday morning, which is looking more unlikely, it could act to stabilize our atmosphere and keep our severe chance at bay.

If we remain dry in the morning and temperatures warm to 90 as expected, we will likely see a thunderstorm complex in the form of a squall line or bow echo move through the region starting around 4 p.m. Should this materialize, our primary threat would be damaging winds. Storms should be moving fast enough that flooding isn’t a big concern. Some hail and an isolated tornado cannot be ruled out, but these two threats are much lower and will require us to either see a bowing part of the line moving southeast and/or discrete storms moving southeast to try and spin.

There is also the chance that the complex of storms misses us to the west and moves more through Ohio than our area, but that is looking increasingly unlikely. The severe threat should end after sunset.

Because of the potential for severe storms, Tuesday afternoon is an Alert Day. Be sure to check in with Pittsburgh’s Action Weather for any fine-tunes/updates to the forecast.

Isolated showers are possible each day through Friday, although no one day looks very wet. Drier conditions and lower humidity air arrive for the weekend.
