We regularly observe snowfall, with annual averages around [insert example: 25-30 inches]. Significant snow events can occur, sometimes leading to travel disruptions. Freezing rain and ice storms are also possibilities, posing particular hazards. Our experience indicates that rapid temperature drops after precipitation can quickly turn wet roads into icy dangers.

Spring's Variability

Spring in New Cumberland is a season of transition and often marked by considerable variability. Temperatures steadily rise from chilly March days into much warmer May afternoons. However, early spring can still bring late-season snowfalls, while late spring often introduces the first severe thunderstorms of the year. This period demands vigilance for rapidly changing conditions, from warm, sunny days to sudden downpours and strong winds.

Summer Heat & Humidity

Summers are generally warm to hot and humid. July is typically the hottest month, with average daily temperatures often in the high 70s to low 80s Fahrenheit, frequently exceeding 90°F during heatwaves. High humidity can make these temperatures feel even hotter. Thunderstorms, sometimes severe with heavy rain and lightning, are common occurrences during the summer months, often fueled by the heat and humidity. Our data highlights July and August as peak months for these convective weather events.

Autumn's Beauty

Autumn is widely considered one of the most pleasant seasons in New Cumberland, with mild temperatures and stunning fall foliage. Temperatures gradually cool from September through November, offering comfortable days. While generally drier, remnants of tropical systems or nor'easters can occasionally bring significant rainfall and strong winds, particularly in late fall. This period is often our most stable, but it's important to be aware of potential coastal storm impacts.
