Weird Weather

It has been raining here for almost the past week and temps have been really cold. Yesterday it actually warmed up a bit, but then it stormed last night. It rained hard and there was plenty of thunder and lightning and even some hail. Thankfully it wasn't big enough to cause any damage. Today it's been sunny except for about fifteen minutes when it got totally dark and just poured down rain. There was hail mixed in with that too. Now the sun is back out and shining like crazy. What gives?
