2005 GMC Envoy Snow underhood

We live in South Dakota and the wind blows a lot. We just had a snow/blizzard and some snow got under the hood and covered the engine. The temps have been below zero for the past couple of days and will continue to hover around the teens and below in the next week or so. I tried to start the truck but it squeeled a bit, so I shut it off. I tried to knock off some of the snow. What should I do to warm it up so I don't damage any belts or more important the engine?

Thank you
