Synopsis – TUE DEC 23 2025

 

A dynamic weather pattern is taking shape for our Holiday week, as a deep trough off the Coast sends an AR into the area. With that, a deep plume of subtropical moisture will surge Eastward by about late Tuesday into Thursday, bringing PWs to 300 – 400% of normal. This could result in locally heavy rainfall totals. Heavy snow is likely in the Sierra and White Mountains, with snow levels dropping to 6,000 feet by Thursday / Friday. Ongoing updates to follow…DMATT
