Todays headlines include our original forecast for developing storm over the Sierra Sunday/Sunday evening with models still trending at 6-12 inches. Areas in the southern Sierra towards Mammoth are slightly favored on this storm. A second push of light snow will occur in the Sierra late Monday favoring the northern mountains. The heavy snow that breaks out in the Sierra Sunday and rapidly moves over northwest Utah and central Wyoming (Weakening). The Wasatch will be a quick hit of light snow (1-4) above 8,000 feet where heavier amounts will be found in the Tetons. Our models indicate 4-8 inches above 9,000 feet in the Tetons. Heavier amounts are likely in Yellowstone and areas just north of Wilson. Light snow will be falling Monday morning near Targhee and JHMR at the base area (Insignificant). Moderate snow will be falling at upper elevations.
THE NEW NEWS IS A STREAM OF HEAVY MOISTURE AIMED AT THE PNW AND BRITISH COLUMBIA NEXT WEEK.
Whistler-Blackcomb is in a direct path especially Tuesday/Wednesday when heavy snow will be falling near the summit and rain at the bases. “Models indicate significant accumulations through Wednesday night in the range of 2 feet on the GFS, 50-60 inches on the Euro, and much less on the Canadian runs”.
We expect amounts to fall in the 2 feet plus range by Wednesday night (Summit) extending into the BC interior (4-9). Snow will continue in in the Whistler high alpine through the end of the upcoming week! I would say “Its possible that 3-4 feet could fall at the summits through the entire week.” Little to no snow will be falling below mid mountain.
The long term forecast for the Rockies puts us in a rut for a while unless the models change after this upcoming storm impacting the Sierra and to a lesser extent the Tetons.
