March 2026 will be remembered for its record-shattering warmth across the country, especially the West. More than 100 monthly records were broken or tied:

This heat has decimated an already meager snowpack across the West, with many locations at 0% of where they should be this time of year:

The good news is that cooler temperatures closer to average will be in place for the next 7 days or so:

During that same time frame, much need rain and snow will fall across the region:

While it won’t make up for the lack of snow this winter, every little bit helps as the rainy season winds down in the West. We are quickly headed towards the dry season and what could be an active wildfire season.
