Forecast Discussion: Current conditions: At 2 p.m. EST this Tuesday afternoon, a weak cool front is losing strength across western Pennsylvania and will likely dissipate soon, as there is no cold air to be found. Temperatures over the next few days will be well above normal and more typical of spring time. Friday may turn out to be the warmest day with temperatures soaring into the 70s with clouds and sunshine. Light winds with little mixing have resulted in air quality being in the moderate range with respect to PM2.5. Tonight will be mostly cloudy with a shower or two, and temperatures will not fall far below the 50 degree mark. *** Wednesday's forecast: Rather cloudy and mild Wednesday with a morning shower Wednesday as the mercury moves into the middle 60s. Light southwest winds with little mixing will send fine particulate to the moderate range once more. Rather mild Wednesday night with low temperatures only dropping to the lower 50s. *** Extended forecast: Temperatures later this week will be more typical of May than late February with clouds and some sunshine Thursday into Friday, with Friday's temperatures possibly getting into the lower 70s. A strong cold front comes through early Saturday with showers and even a thunderstorm, then much colder, blustery, and more seasonable behind this front for Sunday with snow showers a possibility. Moderate levels of fine particulate will continue into the late week period, but a return to good air quality is likely by late in the weekend.---McAuliffe
