CHESTER COUNTY, PA — Fall is flexing its muscles this week, bringing a blustery, wet start before settling into that classic October crispness Chester County knows and loves. Grab the raincoat for the next day or two, but keep a sweater handy — by midweek, the sun returns, and those autumn temperatures drop right on cue.
Sunday: Cloudy and Breezy with a Chance of Rain
Today brings mostly cloudy skies and a 50% chance of light rain, with highs near 63°F. Winds will pick up from the northeast at 15 to 20 mph, giving us that unmistakable fall chill — and a great excuse for another cup of coffee. Rainfall should stay light, less than a tenth of an inch.
Tonight, expect rain to return after 9 p.m., with lows around 52°F and breezy northeast winds continuing at 15 to 20 mph. Showers could deliver up to a quarter inch of rain in some areas.
Monday (Columbus Day): Dreary and Damp
Monday is shaping up to be a washout. Expect steady rain throughout the day, a high around 59°F, and north winds near 15 mph, gusting up to 25 mph. It’s the perfect day for indoor projects or binge-watching something guilt-free.
By Monday night, rain begins to taper off, but clouds linger. Lows stay mild at 52°F, and winds ease slightly to around 10 mph.
Tuesday: Clearing and Calmer
Finally, some improvement! Tuesday turns partly sunny with a high near 68°F. A north wind around 10 mph (gusting up to 20 mph) adds a little edge, but it’ll feel refreshing after two damp days. The evening cools to around 50°F under partly cloudy skies.
Wednesday Through Saturday: Fall Perfection
By midweek, it’s all sunshine and sweater weather.
- Wednesday: Sunny and cool, with highs near 64°F and lows around 40°F — the crisp kind of air that smells like bonfires and pumpkin spice.
- Thursday: Even cooler, with sunshine and a high near 59°F, dipping to a chilly 38°F overnight.
- Friday: Mostly sunny, high near 61°F, low around 41°F.
- Saturday: A perfect fall day — sunshine and a high near 66°F.
The Takeaway
This week in Chester County is a two-act play: rain and wind for the first half, then bright, brisk perfection for the second. Highs slide from the 60s early in the week down to the upper 50s before rebounding toward the weekend, while nighttime temps flirt with the upper 30s.
So, keep the umbrella close now — but by midweek, you’ll want the sunglasses and maybe a hoodie for those golden, leaf-crunching afternoons.
