CHESTER COUNTY, PA — Raincoats and umbrellas will be in high demand at the start of this week, but don’t worry, sunshine and spring breezes will make an appearance soon enough. Prepare for a mix of heavy showers, gusty winds, and even a few thunderstorms before the skies start clearing midweek. Here’s what’s in store:
Sunday (March 16)
Today will feel like spring’s dramatic entrance. Showers are likely in the late afternoon, with a high near 67°F keeping things warm for this time of year. However, the south winds will be on a mission, hitting speeds of 15–20 mph, with gusts reaching a blustery 35 mph. Chance of rain? Sixty percent, and new precipitation could range between a quarter to half an inch. Starting to think about dinner plans? Stay indoors tonight because the real storm rolls in after sundown.
By tonight, showers and thunderstorms take center stage. Some storms may bring heavy rain, with up to two inches expected overnight. Winds will calm slightly to 10–15 mph, but gusts could still hit 30 mph. Temperatures drop to a low of 51°F, ideal for cozying up with a blanket and hot tea but less ideal for any late-night strolls.
Monday (March 17)
Monday morning will likely be a bit dreary with leftover showers possible before 7 a.m. Don’t worry though, the skies slowly transition to mostly cloudy by midday. Temperatures remain cooler than Sunday, peaking at 53°F. A northwest breeze at 10–15 mph, with gusts up to 25 mph, will keep the air feeling brisk. New precipitation amounts will barely nudge the needle, with under a tenth of an inch expected.
Monday night brings calmer conditions. Partly cloudy skies and a crisp low of 32°F will have you reaching for your warmest layers again. Northwest winds at 10 mph may keep things chilly but serene.
Tuesday (March 18)
Cue the sunshine! Tuesday is the pick of the week for outdoor plans as clear skies dominate the forecast. Highs climb to a beautiful 63°F, making it the quintessential early spring day. Northwest winds at 10 mph might gust up to 20 mph, but they’ll bring nothing but pleasant breezes while you enjoy the sunshine. Nighttime stays mostly clear, with lows around 39°F. Ideal picnic weather if you set up before dark!
Wednesday (March 19)
Sunshine sticks around in the morning before clouds slowly creep in by afternoon. Highs will hover near 64°F, plenty comfortable for a midweek coffee break outdoors. The night grows cloudier, with lows at 45°F. If you’ve got an early morning jog on Thursday, you might notice the damp air rolling in.
Thursday (March 20)
Showers make another cameo with a 60% chance of rain in the afternoon. Expect mostly cloudy skies and a high near 61°F. Those looking forward to evening barbecue plans may want a backup activity as rain continues into the night. Overall, new precipitation amounts are manageable, keeping this a less dramatic rain event than earlier in the week. Lows dip to around 33°F as the showers taper off.
Friday (March 21)
Friday brings cooler air and partly sunny skies, with highs only reaching 48°F. Breezy northwest winds will make the day feel even chillier, but at least the skies will stay mostly dry. Enjoy the calm before the weekend starts warming back up.
Friday night will hover near freezing with a low around 32°F. Break out that heavier coat if you’re heading out after dark.
Looking Ahead to Saturday (March 22)
Spring fights back as temperatures return to a mild high of 56°F under partly sunny skies. The perfect weekend vibe for errands, hikes, or patio dining to shake off the winter chill.
The Bottom Line
This week is a mix of wild weather swings, perfect for keeping you on your toes. Sunday and Thursday serve as your rainy bookends, while Tuesday leads the pack for sunny outdoor adventures.
