CHESTER COUNTY, PA — Winter starts the week with a firm handshake and ends it with something closer to a shrug, as temperatures gradually climb and rain chances creep back into the forecast across Chester County.
Sunday: Bright but Brisk
Today delivers a classic January scene: mostly sunny skies paired with a chilly high near 35 degrees. A northwest breeze at 5 to 15 mph will add a bite to the air, making it feel colder than the thermometer suggests. It’s a good day for sunshine lovers, as long as they remember the coat.
Sunday Night: Clouds increase overnight, with temperatures dropping to around 21 degrees. Winds ease and become calm after midnight, setting up a quiet but cold night.
Monday and Monday Night:
Monday stays mostly cloudy with a high near 36 degrees. Winds will be light early before shifting to the south at 5 to 10 mph by afternoon — a subtle hint that change is coming. Monday night remains cloudy and calm, with lows near 27.
Tuesday: A Noticeable Warm-Up Begins
Tuesday continues the cloudy theme but brings milder air, with highs climbing to around 45 degrees. Winds remain light, turning southeast by afternoon. Tuesday night introduces the first rain mention of the week, though only a slight chance — about 20 percent — with lows near 35.
Wednesday: The Week’s Sweet Spot
Wednesday looks like the standout day. Partly sunny skies and a high near 53 degrees will feel downright springlike by January standards. Wednesday night cools to around 33 under partly cloudy skies.
Thursday into Friday: Clouds and Increasing Rain Chances
Thursday stays partly sunny with highs near 49. Rain chances return late Thursday night, with a 30 percent chance of showers after 1 a.m. and lows near 40.
Friday turns more unsettled, with a 50 percent chance of showers and a high near 56. Rain chances continue Friday night, with temperatures holding in the mid-40s.
Saturday: Mild but Unsettled
Saturday keeps the pattern going — partly sunny at times, but with a lingering 40 percent chance of showers and a high near 55. Not a washout, but keep the umbrella nearby.
The Bottom Line:
Chester County starts the week cold and quiet, then steadily warms into the 50s with increasing chances for rain. Winter doesn’t disappear, but it does loosen its grip — at least temporarily.
