I'm not bored at all 

Your destination is "nestled in the snowy mountain peaks" according to the adventure. Your current location is probably damp and chilly at dawn. Heck, feel free to describe a brisk wind coming down from the mountains as you exit the coach. You're already at a not-insignificant elevation. The locals are clad in furs, but a LOT of them trek upward on a daily basis.It never occurred to me to ask: Will the mountains be cold?
Hawthorne is in charge, so feel free to pick out the spells (or potions) he will pay for. For wizard spells, Ruz has:If there are any spells (in particular ritual-ones) that you think that the party could use access to, Hawthorne has enough money in the Consortium's funds to pay for up to two of them.
Healing potions and antitoxins can be found as well. Hawthorne can pay for four of those, but he's going to start to worry about how much money he'll have for unforeseen expenses later (and there won't be any money for a riverboat trip, if he wanted a luxury return to Baldur's Gate). It'll have to be the coach, but that's working out fine so far.

Probably a bit of both. You knew you were heading for the mountains in the east. It would have been easy enough in Candlekeep to have checked the expected weather patterns for this time of year. (Have I established the time of year?) If not, let's say it was late summer when you left, and it's now early autumn.I'm assuming we would have packed cold weather clothes, then before we left? Or maybe bought some in Berdusk or Iriaebor?
