Needless to say, it's been a long, snowy winter for many Americans.Recent
weeks have brought signs of spring to parts of the northern and central
Rockies with highs in the 70s as far north as Montana. That taste of
spring is about to come to a crashing halt as Winter Storm Walda brings heavy snow, very high winds, and a drastic drop in temperatures as the new workweek begins.We have a classic spring storm set to pivot out of the West into the Plains. We've already addressed the likelihood for an outbreak of severe thunderstorms this week with this bullish dip in the jet stream.This
same sharp southward dip in the jet stream, lumbering slowly east,
looks poised to tap deep moisture from the Gulf of Mexico and pull it
north and westward.The combination of higher elevation, strong lift in
the atmosphere, and near-surface temperatures just cold enough is
expected to churn out accumulating snow, heavy in spots. Let's lay out
the forecast for Walda as it stands right now:
