With our San Juan snow pack resting at 50% of average based on a sliding 30 yr SNOTEL average we’d better hope these incoming storms bring some much needed water to our mountains. Warm air temps and southwest flow could be a storm killer for this trough of low pressure. Rain (not snow) would really screw up our Snow-Bank that is so necessary through the spring for a slow melt into the river basins.
The four models I follow show a nice sized trough sliding down the Pacific coast and moving into the Great Basin tonight with a few snow showers but little accumulation then Thursday a possible 3-6″ during the day & early evening. Not much moisture with this disturbance.
Another trough will move into western Colorado late Saturday with all models showing another 2-4″. Neither storm is what we’d like to see in March which used to be our big month of juicy spring storms. Still waiting.
