CHESTER COUNTY, PA — Winter has decided it’s done being polite. After a mild start to the season, this week brings a sharp cooldown, several chances for wintry precipitation, and wind chills that may have you questioning every life choice that led you to live north of the Mason-Dixon Line. Still, Chester County residents know how to handle a little cold — preferably with a warm drink and a reliable forecast.
Today brings partly sunny skies with a high near 40, along with calm winds that shift south around 5 mph this afternoon. It’s a decent day for holiday shopping or outdoor decorating, though you may want gloves unless your hands are made of lava.
Tonight turns much colder. Skies remain partly cloudy as temperatures drop to around 23 degrees. Winds become northerly and could gust up to 20 mph, adding a crisp edge to the late-night air.
Monday is when winter really clears its throat. Expect partly sunny skies but a high only near 30, with a steady north wind between 5 and 15 mph. The combination may leave your face feeling like it’s been lightly sandblasted. Monday night drops even further to around 11 degrees with calm winds — the coldest night of the week and a reminder to let your faucets drip.
Tuesday offers a slight recovery, with sunshine and a high near 33. Winds shift southerly in the afternoon, providing a touch of relief. Tuesday night becomes mostly cloudy with a low around 27, laying the groundwork for midweek changes.
On Wednesday, a weak system moves in with a 40 percent chance of rain and a high near 44. It won’t be a washout, but keep an umbrella handy. Wednesday night holds steady with mostly cloudy skies and a low around 32.
Thursday turns partly sunny with a high near 41, but Thursday night brings another round of unsettled weather — a 40 percent chance of rain and snow before 1 a.m., transitioning to a chance of snow afterward. Roads could turn slippery, especially on untreated surfaces.
Friday keeps the wintry theme going with a 40 percent chance of rain and snow and a high near 37. Friday night dips to around 20 with a continued 30 percent chance of snow — a setup that may bring light accumulations for early risers on Saturday.
Saturday rounds out the week partly sunny but cold, with a high near 30. Not ideal for outdoor fun, unless your idea of fun involves frostbite.
Bundle up, plan ahead, and stay warm. Winter isn’t just knocking — it’s kicking down the door.
