An Arctic ridge of high pressure brought clear skies and light winds over southern MB last night producing some very cold temperatures early this morning. Morning lows were in the minus 35 to minus 40C range in most localities, with Sprague in extreme SE Manitoba registering an exceptional -43.8C! Other spots hitting -40C this morning included Bird's Hill (-40.5C), Piney (-42.5C) and Indian Bay (near Falcon Lake) at -41.0C.
Officially, at least 6 record lows were set this morning over southern MB including:
