Pittsburgh Weather: Weekend starts beautiful, but showers and storms move in for marathon

PITTSBURGH (KDKA) -- Pittsburgh Marathon weekend is starting off with some beautiful weather, but showers and thunderstorms will move in for the biggest races on Sunday.

ALERT: Showers and t-storms Sunday afternoon with damaging winds southwest of Pittsburgh

• Daily average High: 68° Low: 46°
• Sunrise: 6:20a Sunset: 8:15p

Another dry day expected today under high pressure with plenty of sunshine and seasonable temperatures back in the mid-60s. 

A warm front will lift through the region tonight bringing showers and thunderstorms for Sunday. That's why we declared Sunday a First Alert Weather Day.

The biggest threat is Sunday afternoon with damaging winds expected. A lot of us will see rain, but only isolated strong to severe storms are expected south and west of Pittsburgh where there is a "marginal" risk for severe weather, which is a 1 out of 5 on the convective outlook scale.

It's going to be a wet Pittsburgh Marathon, so plan accordingly.

By Monday, things will calm down and we are in the upper-60s with sunshine. Temperatures in the 70s are back Tuesday, but so is the chance for showers mid-week.
