A major cold snap that that sent temperatures across central and southwest Montana plummeting set a number of all-time records for the month of March.
On Monday, Elk Park north of Butte officially set the all-time March record for the state at 46 below zero, but it was far from the only location recording an all-time low.
Also on Monday, officials with the National Weather Service in Great Falls said preliminary readings put Helena's low at minus 29. That has since been updated to 30 below zero, which ties the all-time March mark set in 1955.
Other places setting records for the month include Townsend, Boulder, Butte, Bozeman, Great Falls, Lewistown and Whitehall.
