Southwesterly flow ahead of an approaching trough and attendant cold front continues to bring gusty winds and critical fire weather for much of the region through the evening. Wind gusts are mostly in the 30 to 40 mph range, with some higher gusts over southwest MT, where the strongest winds occur. Some of the mountain peaks and the north to south orientated valleys of the southwest have the potential for wind gusts up to 55 mph at times during the frontal passage, especially when showers are present. The approaching mid-level trough and surface low deepens across southern Alberta after crossing The Rockies with strong westerly flow across MT maintaining very windy conditions through Sunday. Potential for westerly wind gusts in excess of 50-60 mph
exists for much of north-central MT Sunday morning as westerly flow peaks south of the emerging trough in Alberta. The High Wind Warning for areas along The Rocky Mountain Front including The Cut Bank area remains in effect from midnight to 6 PM Sunday evening and the High Wind Watch for the remainder of north-central MT is upgraded to a High Wind Warning, which runs from 3 AM to 7 PM Sunday.
