Narrative:

Due to the severity of the weather and the quick changing conditions; our attention to detail was off. For myself; after a nearly 100 hour month and an early show time to end a trip; I was more tired than initially realized and my attention to detail suffered. Early morning departure out of ZZZ with an xa:00 show time. Aircraft was iced up due to weather. After getting type 1 and 4 applied we began our taxi out to the runway. Bleeds and packs were turned on prematurely and due to the obvious smell of anti-ice fluid; I turned them back off. In the transition from de/anti-ice to our taxi out; the snow intensified and winds went from variable to gusting about 30 kts. Both sets of eyes were outside for the taxi and as we approached the runway we ran taxi and before takeoff checklists. Due to the inclement weather our attention was on that and the bleeds and packs were left off. We take the runway and set up for a static takeoff. As we are accelerating through 80 kts; we get messages associated with anti-ice inop/fail due to the bleeds being off. Captain takes control; we abort not yet knowing what the issue was. As soon as we clear the runway we both look up and realize what the problem was; run the appropriate checklists and continued thereafter. No further issues for the remainder of the flight to ZZZ1.with regard to any phase of flight; double checking is never a bad idea. With inclement weather and/or during times that any crew member may be tired; it is even more imperative to slow down and make sure that the aircraft and crew are on the same page.
