Marine Weather and Tide Forecast for Bishop, CA

SHORT TERM
through Tuesday.

High temperatures across the region will remain above normal today and tomorrow. However, they will decrease a degree or two each day as the Rex Block responsible for this week's pleasant weather begins to break down. The cause of this Rex Block break down? A low pressure system moving into the Pacific Northwest. This system will traverse US Canadian Border over the weekend, moving into the northern Great Plains on Monday. As this system propagates east, we will see additional energy drop in behind it and slide through eastern Nevada/western Utah on Monday and Tuesday. This inside slider will bring northerly winds and seasonal temperatures to the region on Monday and Tuesday. Here in Las Vegas, the southern and western periphery of the valley will have a 20 to 30% chance at seeing their first freeze of the season on Tuesday and Wednesday mornings. Additionally, portions of the Morongo Basin will also see a 20 to 30% chance at seeing their first freeze of the season on Tuesday or Wednesday morning. Winds will begin to pick up and shift to the north on Monday morning and will remain elevated through Tuesday. The strongest winds are expected during the overnight period from Monday into Tuesday. For the vast majority of our forecast area, the northerly winds associated with this inside slider will be a nuisance, but not strong enough to warrant the issuance of a Wind Advisory. The exception to this statement is the Cadiz Basin, Mojave National Preserve, and the Colorado River Valley, especially the area between Laughlin/Bullhead City and Needles. 35 to 45 mph wind gusts are expected in the aforementioned areas beginning late Monday morning and continuing into Tuesday afternoon. Given the dry trajectory of this system, no precipitation is expected to accompany it. This means we are looking at Las Vegas extending their streak of days without measurable precipitation, moving from 3rd place with 146 days as of December 6th into 2nd place (150 days) in the next few days.


LONG TERM
Wednesday through next Saturday.

The weather appears to be fairly benign over our forecast area Wednesday through Friday with temperatures increasing slightly each day. However, model ensembles indicate a progressive pattern with considerable variability in the synoptic flow during this period as the door opens up for multiple Pacific shortwaves to moving across the Pacific Northwest and northern Great Basin. A developing atmospheric river may take aim on central/northern California. This pattern change will be something to watch as it could lead to unsettled weather for our area going into next weekend.

AVIATION
