I'm off up that way tomorrow for a week, I'll report back on conditions but I'm not expecting what snow is left to be a problem. Touch wood, It shouldn't snow again in any amount till late November- ish.
Midgies normally start to come out to play anytime from mid May-ish. They'll stay till the first frost. Headnets, smidge, jungle formula and tiger coils are the only way to fight back.
