Tackling the questions one by one:
Its Spring time. The weather should be fair, but rain might be a potential hazard.
Everything was more or less open until the blackout hit. After dark, any high-end stores would lock up tight to protect against looters, but any places like grocery stores, gas stations, or convenience stores would still be open and taking cash. There's some chaos, but aside from the few thieves hitting electronics or jewelery stores and people seeking shelter for the night, things are still fairly normal on the streets. The common thoughts around town are that the lockdown won't last much longer. Hotels are still open to people who already have a room rented, but due to no credit card system they aren't renting rooms to new arrivals.
The majority of people have 6 or 7 on their Death Clocks, though other numbers are present.
@Pir8Heart: I'm confused, are you saying your character won't be a Demon Tamer yet/at all?
@Monster Guy: Good luck with that. :3
