An update from my Wednesday forecast. This next storm that is currently sliding down the Pacific coast picking up good moisture will begin its migration inland later today into the Great Basin on southwest flow. Today will be warm with increasing cloudiness this afternoon and cooling temperatures.
Probably a few snow showers tonight and early tomorrow morning with minimal accumulations in the mountains then kicks in Sunday as the low pressure trough moves into the San Juans. This storm has colder temps than our Thursday/Friday storm so maybe squeeze a few more inches from it … We could see up to a foot of new above TL but the average is probably closer to 5-10″. As the storm moves east and the flow switches to NW late Sunday, the northwest side of the San Juans (Uncompahgre Gorge in particular) should get a final shot of high precip rates to finish off the event.
