No way to tell about weather, check 15 day forecast, but the mornings will no doubt be in the 40's. If you get rain the tow path will be very muddy, as I just finished the ride and it hadn't rained for 3 days and there were still puddles. At the Pgh.train station, take Liberty Ave. to Boulevard of the Allies to Grant St. then find the Eliza Furnace Trail and you are on your way.
