February snowfall boosts mountain snowpack
Mountain snowpack numbers have improved this month following a slow start to winter.
A La Nina weather pattern was projected this winter and although December and January were mostly dry, local basins have rebounded to the normal range. La Nina episodes in the winter months feature a wave-like jet stream flow across the United States and Canada, which causes colder and stormier than average conditions across the north, and warmer and less stormier conditions across the south.
La Niña winters tend to be banner years for snow across western Canada, the Pacific Northwest, and the northern Rockies. Some of the strongest La Nina seasons in Montana were the winters of 2010-2011, and longtime locals still talk about the notable snow totals in the winter of 1995-1996.
