Why is it 50 degrees in PA in May?

theres a couple reasons why it is 50 degrees in may today.  The first is because much of the northeast is in a trough meaning the jetsteat is further south than your location blocking warm weather from reaching you and allowing cool weather from canada to usher in.  The second is because yesterday a very strong cold front moved through which really blew in cooler air.  High pressure over the great lakes region and a low pressure in the canadian maritimes near quebec caused a stiff northwesterly wind today which made it feel even colder.  This is called a pressure gradient.  Whenever you see a blue H and red L close together on a weather map, its means that area is pretty windy.  Hoever, theres good news for you.  Later this week, starting wednesday and thursday actually, the ridge thats over the plain states in the center of the country will push east getting rid of the trough.  Once the ridge builds in around wednesday the temperatures will respond greatly getting warmer each day just in time for the memorial day weekend.  Friday and saturday should be in the middle 80's under mostly sunny skies and you could perhaps hit 90 sunday and monday especially is you live towards pittsburg or philadelphia.  Weather patterns are constatnly changing; weather likes to balance itself out.  Since its been rather cool the past couple weeks in your region, it will be rather warm, perhaps hot at times for a week at the least, but most likey for a couple weeks now that we're approaching the summer solstice which causes the jetstream to move farther north more often, even up in canada sometimes.  This is why PA and most of the country get very humid and warm during the summer; a jetstream to the north of your area allows warm tropical air from the gulf of mexico to visit you!  This should be the last 50 degree day you'll have to deal with hopefully untill september or october.  I hope you understand what i typed lol.

That's not the way it works...in the summer, it's warmer because the earth tilts on it's axis towards the sun...the suns radiation then has a direct 'shot' at us. In the winter the earth tilts away from the sun, and the suns rays have to go through much more of the atmosphere to get to us...\n\nAs for being cooler...I think it has to do with air pressure at higher altitudes, and being further from the heat being reflected off the ground...

It's November right now in Boston and 40 degrees.  Its cold and its gonna a lot colder until around March when it will (hopefully) start to warm up.  The weather fluctuates all the time so you can never really be sure what the temperature will be.

I don't know....I am from the East Coast (pennsylvania) and it is REALLY hot out today!  It's like 90 degrees with a humidity level of 35% which feels like it could be 100%!  I'm dying outside today.
