Saturday is starting off like a weather freebie in Pittsburgh, mild and crystal clear. As of 5:35 a.m. ET on Saturday, Feb. 28, the KAGC observation site was reporting clear skies and a temperature near 41°F, with the afternoon expected to warm into the mid to upper 50s and a high around 57°F on west winds of 6 to 9 mph. Enjoy the sunshine while it is here, but keep one eye on what happens after dark.
Overnight Slick Spots Possible
Late Saturday night into Sunday morning, overnight Feb. 28 to March 1, a fast-moving system could bring rain that briefly mixes with snow or freezing drizzle. Little to no accumulation is expected, but even a light glaze can turn bridges and ramps into surprise skating rinks. Lows should dip to around 32°F before drier air moves in and mostly sunny skies return Sunday afternoon. There are no watches or warnings in effect this morning, but the National Weather Service is flagging about a 40% chance of overnight precipitation and urging extra caution for early morning drivers.
Monday Night Into Tuesday: Watch The Freeze
A second system, Monday night into Tuesday morning, overnight March 2 to 3, carries a higher risk of freezing rain before temperatures climb enough to flip everything to plain rain. Tuesday's high is forecast near 51°F, with midweek readings rising into the 50s and possibly reaching about 67°F by Thursday, a rapid warm-up that will favor steadier rain and boost the odds of heavier downpours or stronger storms later in the week. The National Weather Service forecast discussion calls out the increasing freezing rain probabilities and the early March pattern shift, so if you are on the road Tuesday morning, plan for slick spots before the changeover.
What To Do
Keep an ice scraper handy and build in a few extra minutes for morning commutes if you are out before 8 a.m. Sunday or Tuesday, with bridges and overpasses the most likely trouble spots. Flying early Tuesday. Check in with your airline about potential delays tied to the freezing rain window. This forecast has been updated to reflect rising freezing rain odds, so you may want to compare it with the earlier outlook from yesterday.
