Narrative:

We deadheaded to start our trip. We arrived late. When I arrived at the aircraft we were taking we were about 15 minutes from scheduled push. The agent let me down the jetway and asked if I would let the flight attendants know that the passengers would be coming down. I said that would be fine. He also notified me that the paperwork was in the aircraft. When I arrived at the aircraft; the flight attendants were all on board but the aircraft was cold and dark and not plugged in or hooked up to the air. I said hello to the flight attendants and began my checks so that I could start the APU. As I was doing this; the passengers began boarding. I didn't notice that the passengers were boarding until after I had gotten the APU started. The aircraft was an -800 and we were [going to have a light passenger load]. I knew the passengers would not take long to board; so I wasted no time completing my preflight and walk around. After my walk around; the captain and I discussed the plan for deicing as it was snowing. The captain and I went over the flight plan and the mels that were on the aircraft. I wasn't thinking about the weather [at our destination] because we had just come from the west and I thought the weather to be a nonissue. I also assumed the captain had looked at it and everything was fine. We noticed that we didn't have a weather packet during the climb out. We proceeded to use the ACARS to get the appropriate weather and NOTAMS for our flight.[we must] include a weather packet with every release even if that means printing an updated weather packet closer to departure. [We should] allow aircraft to be left powered up without pilots onboard. I shouldn't have assumed that the flight attendants and aircraft were ready to board without going down to the aircraft first.

Title: After deadheading in; running late for departure; heavy snow; finding a cold unpowered airplane already being boarded by passengers and dealing with a harried; uncooperative gate agent all combined for a rushed and incomplete preflight environment during which the flight crew failed to note there was no weather packet contained in the flight papers until after takeoff.
