Marine Weather and Tide Forecast for Bishop, CA

DISCUSSION
through Thursday.

Increasing cirrus cloud cover continues to overspread the region this afternoon in advance of a weakening Pacific low that will bring a return of unsettled conditions to the area. Breezy southwesterly winds have already surfaced across most of the area and winds will remain elevated through the weekend as pressure gradients tighten. The initial low will move inland Saturday morning, only to be replaced by a deeper trough moving in on its heels. This second low will bring more widespread and gusty winds to the region on Saturday and Sunday. Additionally, this second system will provide a reinforcing shot of cooler air, which will knock temperatures down to around 10 degrees below normal on Sunday and Monday.

Precipitation expectations remain fairly minor, and largely confined to the Sierra through Saturday, before precipitation chances shift eastward Sunday and linger Monday as the deeper low moves through. Precipitation totals will be limited outside of the Sierra, largely favoring the higher terrain - though some isolated thunderstorm activity could being a few locally stronger downpours. Across the Sierra, light snowfall generally above 7000 feet is expected as early as Saturday morning, though the brunt of snow accumulation is expected Saturday night into Sunday when 4-8 inches of snow may fall in locations like Aspendell, with up to a foot near the Sierra Crest. Further east across the Great Basin and Spring Mountains, light snow accumulations will be possible as well but are not expected to be enough to cause any noteworthy impacts. High pressure will gradually rebuild next week with a warming and drying trend expected.
