CHESTER COUNTY, PA — For Chester Countians, it’s time to bundle up and prepare for some wintry weather. A high-pressure system is passing off the Carolina coast today, bringing with it a period of benign weather conditions. This will be followed by a low-pressure system tracking into the Ohio Valley late Wednesday and a secondary low developing east of the Appalachians that same day. This will bring a round of widespread precipitation and breezy conditions to our area, including a period of wintry weather to eastern Pennsylvania and northern New Jersey.

Precipitation Outlook

The precipitation associated with this system could begin as early as Wednesday morning. Light snow is expected in Chester County, mainly after 10 AM Wednesday morning, with precipitation continuing through early Thursday morning. Accumulations should range from 1 to 3 inches across most areas, with higher amounts possible in some locations. There may also be some sleet or freezing rain mixed in with the snow at times—especially near the I-95 corridor—which could lead to slippery roads and hazardous travel conditions for motorists.


This wintry weather is likely to cause some disruptions to daily activities in Chester County over the next few days, so it’s important for residents to remain mindful of changing conditions during this time. Motorists should use caution when driving on area roadways as accumulations may create icy spots on bridges and overpasses; they should also plan accordingly if they are traveling by air since flight delays are possible due to a wintery mix of snow and sleet that could affect nearby airports. Additionally, residents should take steps to protect pets and outdoor plants from cold temperatures that are forecasted over the next several days.
