This afternoon we’re leaving behind the beautiful, warm days of autumn… Currently clouds and wind are invading the area. There is a surface cold front and a short wave trough moving into the San Juan mountains late this afternoon to early evening bringing rain and rain/snow mix to the lower elevations and snow to the alpine terrain.
As the cold front stalls in our mountains a nice combination of winds, orographic lift and vorticity in the atmosphere should produce 8-12″ of snow and maybe more to the higher elevation west facing terrain above 10,000′.
Most of this short lived storm will put down it’s moisture tonight into Tuesday morning… then another short wave disturbance Tuesday morning will keep snow production going until the afternoon. By Wednesday sunny/breezy conditions and slightly warming temperatures return to the area.. Enjoy the first significant storm of the season just in time for Dia de Muertos and Halloween
