Forecast Discussion: Current conditions: Much warmer air is dominating the area this Tuesday afternoon on a southwesterly flow. With the sun out, temperatures moving into the 70s will break today's record high for Pittsburgh of 68 set way back in 1891. *** Wednesday's forecast: A cold front will cross the area early Wednesday afternoon with showers and a thunderstorm, but before it does, the record high for Wednesday in Pittsburgh of 73 degrees set in 1997 might be challenged. Winds shifting into the west and northwest will bring fine particulate down into the good range. *** Extended forecast: The cold front which will move through the area on Wednesday will get hung up to our south on Thursday, and a northerly flow will bring in much chillier air with another round of mainly rain. Across northern areas, the air might even be cold enough for sleet and freezing rain for a time Thursday, as temperatures struggle in the 30s. Fine particulate will be in the good range. Additional showers are likely Friday into Saturday as the stationary front comes back northward as a warm front, and things will turn a little warmer, especially by Saturday. Lighter winds and warmer air attempting to return will bring increases in fine particulate, and moderate readings are possible by Saturday. Sunday may be the warmest day as the next cold front approaches with showers and even a thunderstorm.---McAuliffe
