Forecast Discussion: Current conditions: At 2 p.m. EST this Thursday afternoon, record warmth continues across the region as the mercury surpasses the 70 degree mark in parts of the area. Mixing has led to decreases in fine particulate from earlier in the day, but a few locations remain low moderate. A shower in parts of the area this evening, otherwise partly to mostly cloudy and rather mild overnight with lows in the middle 50s. *** Friday's forecast: Record warmth will prevail on Friday with southwesterly winds. While fine particulate will start the day moderate, a decent amount of mixing will cause concentrations to decrease in the afternoon, but low moderate air quality will occur on average across the region. The record high for Friday in Pittsburgh is 70 set initially in 1875 and tied in 1906. A strong cold front then approaches the area later Friday night with a shower or two. *** Extended forecast: Much colder air will move back into the area late Saturday into Sunday behind a cold front slated to move through early Saturday with showers and a gusty thunderstorm. Gusty winds from the northwest will send temperatures back down to more typical late February levels, but improve air quality to the good range. Snow showers are likely Saturday night into early Sunday, with accumulations over the western slopes of the Appalachins. Lows Saturday night will nosedive into the middle 20s. A weak area of low pressure coming out of the Ohio valley on Monday may bring a bit of snow mixed with rain, then a stronger low pressure area may produce more rainfall by the middle of next week. ---McAuliffe
