Why take these trips in the summer?
Central Pennsylvania is situated right around 41ºN
77ºW and in the Appalachian Mountains,
placing it just on the border between 3 different climate types: humid
continental forest (Dfa), marine (Cfb), and humid subtropical (Cfa).
What does this mean? It means that Central PA winter temperature
can dip close to 0ºF, with an average low
temperature of 26ºF (indicated by the first
letters "C" and "D" in the above mentioned climates). Central PA
usually gets 30-59 inches of snowfall (although in recent years it has been
much less). This does not make good weather to travel in, especially
since many of the roads are country roads in the mountains and you will need
to spend a great deal of time outdoors.
Summer can get up to 100ºF with an average
temperature of 73ºF (indicated by "a" and "b"). The average annual
precipitation amount is generally 40-59 inches, and is evenly distributed
throughout the year (indicated by the second letter "f").
Central PA is close enough to the east coast that it enjoys the ocean's
moderating effect, preventing the temperatures from going to extremes.
However, summer may be a little more humid than the winter due to moisture
from the Atlantic Ocean and from other maritime tropical air masses, so
expect to see plenty of thunderstorms.
Overall, a nice mixture of cool,
dry periods and hot, humid periods makes summer the ideal time for taking
trips around Pennsylvania. Just make sure to have an umbrella
nearby...just in case.
