Southwest PA Ozone/PM2.5 Forecast

Forecasted AQI for Ozone Air Quality Index Scale Forecasted AQI for PM2.5
October 26, 2014

 

Date: Sunday, October 26, 2014
Action Day?:  No
Temperature:  Near 60
Discussion:
On Sunday, mostly sunny skies will prevail over western PA as the frontal system, which was across the Great Lakes on Saturday, drops southward through PA. As a result, expect the winds to turn more out of the west, northwest, allowing a cooler and drier air mass to build in. In fact, afternoon highs are only expected to make their way near the 60 degree mark. The combination of the cooler and drier air along with strong afternoon flow should be enough to drop PM 2.5 levels back into the good category.

Extended:
As we take a peek into this week, we notice that the week will start off pleasant, thanks in part to a new area of high pressure building in over the eastern US. After a brief cool snap on Sunday, an area of high pressure will extend eastward across the East Coast. As it does, the winds over our area will swing out of the southwest, allowing warmer and more humid air into the region. As a result, highs for the first couple days of the work week will be in the 70s. Air quality should follow suit and rise back into the moderate range due to a more modified air mass building in from the west. Toward the middle of the week, the first of two frontal systems will press through the region. The first front, slated to push through on Wednesday, will provide a shower or two before moving off to our east. A cooler and drier air mass will build back into the region. A second frontal system will push in just in time for the weekend and provide a reinforcing shot of cool and dry air for western PA. Needless to say, expect PM 2.5 levels to drop back into the good category during this period. --Nolan
