Chester County is sure to experience some significant changes in weather this week. Starting today, high pressure will build south of Chester County, creating temperatures that remain above normal. This high pressure will move offshore late tonight and southerly flow will usher in higher temperatures midweek. Tuesday through Wednesday, a frontal system will arrive, bringing rain showers, fog, drizzle and possibly record-breaking warmth on Wednesday. Thankfully for Chester County residents, cooler and more seasonable conditions return later in the week as colder high pressure moves into the region from the west.

What to Expect Today & Tonight

Chester County will be experiencing some fluctuating weather elements today and through tonight. The day will bring partly sunny skies, with a high near 59 degrees and light, variable winds turning to a westerly direction in the afternoon. As night descends, there is a slight chance of rain before 11 PM that carries on until 4 AM, accompanied by patchy fog and mostly cloudy skies. The temperature drops to around 44 degrees with a calm wind transitioning to southeast at around 5 mph. There is 20% chance of precipitation during this time frame.
