CHESTER COUNTY, PA — A damp and occasionally wintry start will give way to a modest midweek warmup before the weekend settles back into seasonable February chill across Chester County, PA. The overarching theme for the next seven days is unsettled but manageable—no major storms, yet enough rain and light snow to keep commuters alert and outdoor plans flexible.
Today begins with patchy freezing fog before 9 a.m. and lingering fog through mid-morning, which could create slick spots on untreated roads and reduced visibility during the early commute. Clouds dominate, and a chance of rain develops mainly after 3 p.m. Highs will reach about 41 degrees, with light east winds around 5 mph. While rainfall totals remain light—generally less than a tenth of an inch—the evening drive could turn messy. Tonight, rain mixes with snow before changing to all snow after 7 p.m. Overnight lows dip to around 29 degrees, and 1 to 2 inches of accumulation are possible. It’s not a blockbuster snowfall, but it may be enough to coat secondary roads and sidewalks by Tuesday morning.
By Washington’s Birthday, skies gradually brighten. After a cloudy start, sunshine returns, with highs again near 41 degrees. North winds between 5 and 10 mph will keep the air feeling brisk. Monday night remains mostly cloudy with lows around 28 degrees, so any leftover moisture could refreeze. Tuesday brings a modest improvement, with partly sunny skies and highs climbing to 46 degrees. Tuesday night stays mostly cloudy, with lows around 33 degrees, marking a slight moderation overnight.
By Wednesday, however, another weak system approaches. Expect mostly cloudy skies and a 30% chance of rain developing after 1 p.m., with highs near 46 degrees. Wednesday night carries a lingering chance of showers before 1 a.m., and lows hold milder at 37 degrees. Thursday continues the gradual warmup, with highs reaching 52 degrees under partly sunny skies, though scattered showers remain possible. That stretch may offer a narrow window for early spring chores, but keep an eye on passing showers before washing the car or leaving patio furniture uncovered.
Looking ahead to the weekend, Friday trends cooler again with mostly cloudy skies and a 50% chance of rain. Highs hover near 48 degrees, with overnight lows around 33. Saturday shapes up as the brighter day of the two, with partly sunny skies and highs near 46 degrees—comfortable enough for a bundled-up hike at Marsh Creek or youth sports on damp but playable fields. While not a picture-perfect weekend, it’s serviceable for outdoor plans with the right layers.
