PA Ozone/PM2.5 Forecast
November 30, 2015
Date: Monday, November 30, 2015
Temperature: Upper 40s
On Monday, the skies will turn partly sunny as the main energy associated with the front re-centers itself over the Plains. The northern edge of the front will dissolve as higher pressure builds over the Northeastern US, allowing the clouds to give way to some sun. Temperatures will once again hover near normal. The light winds along with the seasonable temperatures will lead to an increase in PM 2.5 levels, with readings possibly rising back into the low moderate category.
As we take a peek at this week, we notice that temperatures will start off near normal as a new area of high pressure builds over the northeastern US. This high will move off the New England coastline just as a new area of low pressure makes its way up from the Plains into the Great Lakes. This system is likely to impact us in the Tuesday to Wednesday period as the low crosses the northeastern US on its way into the northern Atlantic. On the backside of the storm system, a new high pressure building over the Plains will promote colder, drier air to build in for the remainder of the week. By the end of the week, the high will build in over the Mid-Atlantic, promoting lighter winds and more seasonable temperatures. Overall, air quality levels are expected to rise early in the week as high pressure builds over the northeastern US. Once the storm system moves through and the cooler, drier regime builds in, expect PM 2.5 levels to fall back into the good range. --Nolan
