Pittsburgh Weather: Early season blast of fall air arrives Tuesday afternoon
PITTSBURGH (KDKA) - Break out the long sleeves and jackets, cooler air is heading our way.
The blast of fall air arrives on Tuesday afternoon. Rain showers could begin as soon as 1 p.m. for the area with off-and-on rain showers expected for the rest of the day. The real impact of the front won't be felt until Wednesday with highs hitting just the upper-60s.
While highs will get back to the 70s by the weekend, morning lows on Friday, Saturday and Sunday are expected to dip below 50-degrees for most of the area including Pittsburgh. I expect most places up along I-80 will fall below 45-degrees for morning lows on Saturday morning.
While cool air arrives Tuesday, Monday will be seasonal with highs in the upper-70s and morning lows dipping to near 60-degrees. Skies will be partly cloudy with just an isolated rain chance. So far this month, we are off to a top-15 'hottest start' to the month of September.
