Pittsburgh Weather: Spot showers, cooler temperatures, poor Mon Valley air quality
PITTSBURGH (KDKA) -- Skies will be partly to mostly cloudy today with off-and-on rain showers expected to roll through the area.
Today: Mon Valley air quality will remain in the orange range today. Everyone else is in the yellow 'moderate' range
Any Alert Days Ahead? Not likely. Outside shot for Thursday.
Aware Cooler weather will be in place this weekend.
The area remains under the influence of an upper low located in southern parts of Quebec today. This will keep skies partly to mostly cloudy for the day with off-and-on rain showers expected to roll through.

I can't guarantee the six hours between then will be dry but they should be the driest hours of the day.
Even outside of that time, it doesn't appear rain will be widespread. I am keeping the 40% chance for rain for the day today with the best chance for rain probably already passing.
At this point, I am going to keep Wednesday dry, with rain and storm chances returning on Thursday as another upper low slides by to our north.
At this point model data continues to show rain and storms coming in around sunset from the west.
Weakening cells should still be strong enough to bring a severe weather threat. Large hail and strong winds will be the main threat.
These storms will eventually change over to heavy rain producers with frequent lightning as they race east.
Back to today, highs should be near 80 degrees with noon temperatures in the mid-70s. Winds will be light, coming in out of the southwest at around 5-10 mph.
There will be times with plenty of sunshine, but other times with overcast skies. I will split the difference and call today partly cloudy.
