As Rain Ends, Big Temperature Drop Expected Tuesday

MOUNT HOLLY NJ – A flood advisory for Montgomery, Berks and Chester counties issued early Sunday (Feb. 28, 2021) by the National Weather Service office in Mount Holly has officially ended, but AccuWeather reports rain is expected to continue into Monday (March 1) morning. It, combined with continued snow melting, may create minor flooding in low-lying areas, forecasters warned.

A flood advisory means river or stream flows are elevated, or ponding of water in urban or other areas is occurring or is imminent.

The Weather Service reported the runoff could affect some portions of the region’s most heavily traveled highways. They included the Pennsylvania Turnpike between exits 296 and 359, Interstate 76 between mile markers 327 and 351, and Interstate 676 between mile markers 0 and 1.

“Cold air will follow the rain, creating a return of wintry and windy conditions into Tuesday (March 2), State College-based AccuWeather said. “It is possible for a quick coating of snow to accumulate in some locations for a brief time. Road conditions will be slippery as well, leading to possible travel delays, it added.

Cities like Philadelphia and its northern suburbs, after having a couple days near the 50-degree mark, will be stuck in the 30s and possibly lower Tuesday.

“For the beginning of March, temperatures of this level are as much as 10 to 20 degrees below normal.” Drivers on secondary roads “will want to be hyper-aware of their surroundings and watch for a drastic change in visibility and road conditions,” according to AccuWeather.
