Depends on how cold the air actually is Canada when it happens. Currently large area of -10s, some -20s in the northwest territories. -40s are just north of the Canadian archipelago. As the dome of high pressure builds, the air will get colder and get pushed further south out of the Arctic. The stronger the high the more intense the push.
If we start seeing -30s sink south along the Canadian Prairies then it will get quite cold, should such a high develop.
If there is a 1060HP+ high pressure dome sitting in Montana early next week, DFW will be in the single digits no question. Big IF
I don’t care who you are... that’s cold!

Would be very hard to get precip to stick around with that kind of push of cold. Maybe on the back end once the high pressure has relaxed a bit.
