7 DAY POWDER FORECAST
Summary 4/12/2017 8AM MST
I’ve been struggling to find a deep morning over the next 3 days. Your best bet will be the Sierra Thursday morning where 4-8 will fall tonight and another 3-5 during the day. The Cascades could also be in the mix with snow and rain continuing for the next 2 days. The leftovers could land some decent snowfall into central Idaho (Northern Sawtooths) that edges north into Montana and Wyoming Thursday night. While some of us are putting your boards and sticks away for the season something tells me that another decent storm will happen next week.
Short Term Forecast
Snow will be begin falling above 7,000 feet late today in the Sierra. Strong winds will likely impact lifts at many resorts at higher elevations. Light to moderate snow will turn heavy by daybreak Friday when colder air brings snow to lake level. Some of this snow may be convective with the cold air and produce several inches in short time spans. The heaviest snow may be falling from 4AM-9AM Thursday. Models favor northern areas of the Sierra with much less towards Mammoth. The highest peaks of Squaw or Sugar Bowl may grab storm totals of 9-14 inches. Expect less at the base.
This is one of those storms where the 5AM report might show 3-7 inches but at 9AM when lifts open there is 5-10. It’s not going to be anything epic but it’s mid April and it’s snowing at the base! Snow showers in the Sierra will continue through Thursday evening before tapering off (Additional light snow during the day).
Elsewhere my eyes on the Cascades. Crystal Mountain nabbed 6 inches overnight and has seen 20 plus in the past 7 days! Temperatures are above freezing at the base with high 20’s at upper mountain. Expect moderate amounts of smooth cream with forced wet face powder shots. Temperatures in the Cascades will drop slightly tonight with moderate snowfall above 4,000 feet into Thursday morning. There is a good chance of another 3-6 tonight and 3-6 Thursday! Snow will favor the south Cascades. I am in chase range of Crystal this morning but elected to bail due to temperatures being on the warm side. Thursday might offer better quality.
In the Rockies moisture pushes north through the Tetons Thursday PM through Saturday AM. Nothing looks too impressive but a decent freshening for Grand Targhee should happen for Friday AM and Saturday AM (2-4 or more each 24 hour period). Southern Montana is also in the mix so not surprised to see light snow into Big Sky or Red Lodge. Utah and Colorado are out of the mix being too far south (Snow showers possible in northern Utah).
Pattern stays very unsettled in the Sierra late this weekend and early next week. Systems will continue to move into California. Temps may be warmer than the previous storms. Focus seems to be less on the Cascades next week with an uptick in the Sierra. Some of these storms might aim towards the Wasatch and most of Colorado by mid next week.
