04 Feb SAN JUAN MOUNTAINS WEATHER FORECAST: STORM FOR THE WEEKEND?
Looks like the San Juans will have clear, sunny and dry conditions with daytime temperatures into the mid 40’s through Thursday, but with a few mid/high level clouds invading on Tuesday. Zonal flow and high pressure will dominate the region then beginning late Thursday clouds will begin to move in ahead of another Gulf of Alaska storm that is brewing right now (check out the Infrared loop) and will soon begin it’s southern migration down the west coast moving onshore Thursday.
None of the three models I’m watching agree on timing or duration of the storm, but all have the closed low moving into the Great Basin on Thursday night/Friday morning and arriving in the San Juans depending on which solution you choose between Friday and early Saturday on SW flow.
As most all storms arriving from the southwest, southern and southwestern aspects above 11,000′ will be favored for snow. It’s too early to tell right now how much moisture this system will carry so I’ll post an update later in the week.
