Forecast Discussion: Current Conditions: As of 2 PM on Monday, mostly cloudy skies prevail over the region as a cold front, which pushed through our area late yesterday, continue to move off to our east. The area of low pressure associated with the frontal system is still hovering over the New England region. The cyclonic rotation of this low is spinning rain showers over much of the Northeastern US. Right now, rain showers are falling over portions of our region as showers continue to push in from the northwest. Gusty winds coupled with the clouds and rain are helping to keep temperatures confined to the upper 60s. Air quality levels also remain low, with ozone and PM 2.5 concentrations hovering in the good category. Expect the good air quality to persist through the day tomorrow as cool and dry conditions remain in place over our area. *** Tuesday's Forecast: So for Tuesday, partly sunny skies will persist over western PA as an area of high pressure over the Midwestern US begins to take hold of the weather over our area. The frontal system which plagued the region on Sunday and Monday will now be off to our north and east. The presence of the high will not only lower the wind speeds over our area but should also keep the flow out of the northwest. The northwesterly flow will, in turn, force cooler and drier air across western PA. As a result, expect high temperatures to only creep near the 70 degree mark. The combination of the cool and dry conditions over our area (along with the origin of the air mass) will keep ozone and PM 2.5 levels well within the good threshold. *** Extended Outlook: Over the coming days, expect temperatures to remain below normal as a series of disturbances swing through the region. Here is how things are shaping up... On Wednesday, expect more clouds to move into the region as another disturbance swings through the Northeastern US. Once this disturbance swings through, expect the core of the cool air over the Northeast to migrate back into eastern Canada. In fact, our winds should swing more out of the west, southwest by Thursday, returning temperatures to close the 80 degree mark. The southwesterly flow will also create the opportunity for more instability. Therefore, the threat of afternoon showers will increase as we head into the weekend. Overall, air quality levels will remain in the good range early in on. Once the system swings through the region on Wednesday, expect the air quality levels (primarily PM 2.5) to increase back into the moderate range as the warm and humid conditions returns. --Nolan
