Forecast Discussion: Current conditions: Much colder air is charging into the area on brisk northwesterly winds this Tuesday afternoon. Temperatures are over 30 degrees colder than Monday's mild readings with wind chills down in the teens. Snow showers will linger this evening, then very cold overnight under a moonlit sky. Low temperatures will fall to the middle teens, which is only slightly above the daily record for Pittsburgh of 13 degrees set in 1911. *** Wednesday's forecast: Less wind with times of clouds and sunshine Wednesday, with highs only recovering to the 30 degree mark. With clean background air still in place, fine particulate concentrations will remain in the good range. *** Extended forecast: Temperatures will moderate some on Thursday before the next cold front comes through early Friday, followed by another shot of cold air later Friday into Saturday. Moderate air quality is possible Thursday into Friday, with good air quality forecast by Saturday.---McAuliffe
