Forecast Discussion: Current conditions: At 2 p.m. EST this Friday afternoon, record warmth continues across the region with temperatures moving well up into the 70s. The all time record high for February in Pittsburgh is 77 degrees set February 8, 1900, and we will get close to that record this afternoon. Southwesterly winds have created a greater than expected level of mixing, so fine particulate is averaging in the upper good to lower moderate range. Quite mild tonight with a shower later on as temperatures fall back into the middle 50s. *** Saturday's forecast: A cold front will move through the region early in the day Saturday, and bring showers and thunderstorms with it. Winds will shift into the northwest by afternoon and temperatures will start to fall. Plenty of strong mixing near and behind the front will promote low levels of PM2.5. Windy and rather cold Saturday night with snow showers, with light accumulations in the mountains to the east of Pittsburgh. Lows will plummet into the middle 20s. *** Sunday's forecast: High pressure will build into the area Sunday, with clouds and sun and seasonably cold air. Plenty of clean background air will again bring low levels of fine particulate. *** Monday's forecast: Monday will turn out mostly cloudy as high pressure shifts off the east coast and there is an influx of moisture from the south. Light winds and higher relative humidity levels will boost particulate matter near the surface once more. *** Extended forecast: A series of low pressure areas coming out of the Midwest and passing just north of us will bring unsettled weather by the middle of next week, with rounds of rain possible Tuesday and again on Wednesday. Turning brisk and colder by later on in the week with rain or snow showers possible with a return to good air quality. ---McAuliffe
