Building humidity and daily thunderstorms will lead to a tropical steambath for Pittsburgh as June gives way to July.
Temperatures and humidity will be on the rise into Tuesday as tropical air from the south pours in.
High temperatures will gradually increase through the 80s.
The combination of the warmth and humidity will create even higher AccuWeather.com RealFeel® temperatures, which will prove to be dangerous for those engaging in manual labor and strenuous activities Monday and Tuesday.
The steamy air will also set the stage for daily rounds of showers and thunderstorms.
Through Monday, the thunderstorms will generally pose a nuisance to those with outdoor activities. Such interruptions can occur at PNC Park Sunday afternoon as the Pirates take on the New York City Mets.
Remember you are close enough to be struck by lightning if you hear thunder.
With so much moisture present, it is not out of the question for one or two thunderstorms through Monday to unleash flooding downpours.
Concern for the thunderstorms to turn severe with more frequent downpours, damaging winds and hail will increase on Tuesday as a cold front slices into the tropical steambath.
The shower or thunderstorm chance will linger through Wednesday and Thursday before a drier and more comfortable Independence Day unfolds on Friday.
