PA Ozone/PM2.5 Forecast
August 1, 2014
Date: Friday, August 1, 2014
Temperature: Low 80s
On Friday, a mix of sun and clouds will prevail through the day as a disturbance makes its way through the southeastern US. The southerly flow over our area in advance of this system will help keep conditions seasonably warm and more humid. Therefore, this disturbance should trigger shower development as we head into the afternoon. The additional clouds and rain chances during the afternoon will hold ozone levels down but should help to keep PM 2.5 levels in the low to mid moderate category.
Over the coming days, expect temperatures to remain near normal as a weak disturbance impacts our area early in the period. Here is how things are shaping up... Over the weekend, expect the threat of showers to persist over our area each day as a weak storm system makes its way up along the East Coast. This system should push out into the Atlantic during the early portions of next week. As it does, our flow will turn more westerly and result in seasonable temperatures over our area. Another weak frontal system will pass through western PA during the second half of the week, resulting in showers over our area. This frontal passage will set the stage for a larger system to push through during the weekend. Overall, air quality levels are expected to remain elevated during the period, primarily due to PM 2.5's ability to thrive in a warm and moist environment. --Nolan
