Pittsburgh: Severe Storm, Flooding Threat to Precede Cooldown

After only spotty rainfall during the first part of this weekend in the Pittsburgh area, the risk of severe thunderstorms and flash flooding will ramp up quickly by Sunday.

As much cooler air plunges into the Midwest thanks to a southward trip by the Polar Vortex, warm and moist air will surge northward in the East Sunday, Monday and into Tuesday.

The storms into the first part of next week will bring the risk of damaging wind gusts initially but can be followed by repeating downpours and the potential for flash flooding.

The weather pattern next week is likely to bring extended disruptions to travel and outdoor activities along much of the Atlantic Seaboard, including the South.

Dramatically cooler and less humid air will spread into the region during the middle of the week that can bring some surprisingly low temperatures for the middle of July.

The weather at Minneapolis early next week will be more appropriate for football, rather than baseball for the Home Run Derby and the All-Star Game.
