PA Ozone/PM2.5 Forecast
February 2, 2015
Date: Monday, February 2, 2015
Temperature: Near 20
On Monday, mostly cloudy skies will continue to prevail over the region as the storm system begins to move east of our area. Snow is likely to continue through the early morning hours. However, snowfall will end by late morning as the main system begins to move offshore. Overall, afternoon temperatures will dip to near 20 as the winds turn northwesterly and drive a cooler and drier air mass into the region. In fact, winds should also pick up in intensity (remember the winds on Friday... this will be similar). Therefore, it is the combination to these three factors (cold, dry and windy conditions) that will keep PM 2.5 levels from rising out of the good range.
As we take a peek into this week, we notice that the week will start off on the cool side as a storm system moves through the region. Temperatures will really take a dive on Monday as a new area of high pressure (and its northwesterly wind flow) moves into our west. As the high moves over our area on Tuesday, expect some moderation in temperatures as the winds die down and the sun reappears. Temperatures will warm further on Wednesday as our high pressure system moves east of our area. A new clipper system will swing through the Northeastern US on Wednesday, providing a slight chance of snow before driving a reinforcing shot of cold and dry air into the region to end the work week. Overall, air quality levels are expected to be at their peak in the Tuesday / Wednesday time frame as the warmest temperature reside over the region. Otherwise, it will be the cold, dry and windy conditions that keep PM 2.5 levels from rising out of the good range. --Nolan
