Tuesday – Wednesday Showers:
Tuesday into Wednesday a cold trough and cut-off low move into the Great Basin to our east. That will bring colder air with highs only in the 40s on the mountain Tuesday and Wednesday, with 30s up top. We could also see gusty winds Tuesday with gusts up top of 50-60+ mph at times, possibly affecting some upper mountain lift operations.
We will have partly sunny skies with clouds and the chance for showers increasing both days by late morning into the early evening hours. Snow levels mainly above 7000-7500 ft. but they could be dragged lower if we see heavier bands of showers form over the mountain, and then possibly to the base at night.
Only expecting snow to accumulate on colder surfaces like the snow already on the ground, especially on the lower mountain and at the base if we see any snow. Likely some rain showers at the base with a chance of a change to snow under heavier showers, especially Tuesday evening. We could see 1-6 inches of wet snow accumulate in total on the mountain through Wednesday evening.
Thursday – Friday:
High pressure builds back in as the low moves east starting Thursday. Sunny skies return with highs warming into the 50s at the base and 40s above 8000 ft.
High pressure may continue to build over the West Coast through the weekend and into the week of the 19th. Highs warming into the 50s for the upper mountain and 60s at the base.
We are watching a strong typhoon forming near the Philippines that may get caught up in the westerlies during the last week of April. We will keep an eye on that to see if that could help to shift the pattern and bring in some precipitation during the last week of April.
