Marine Weather and Tide Forecast for Bishop, CA

DISCUSSION
through next week.

One more weak shortwave will drop south out of the eastern Great Basin and into northern Arizona today. This feature is weak and will have little consequence on our regional weather besides an enhancement of northerly winds, especially down the Colorado River Valley, through the evening hours. Otherwise, temperatures will continue to slowly climb today and Saturday as a transient high pressure ridge builds into the Southwest. This will allow temperatures to top out a few degrees above normal today, and climb a few more degrees Saturday.

By Sunday, a deep cut-off low off the California coast will begin to approach the region. This will induce an increasing southwesterly flow aloft, and afternoon winds will become gusty especially across our western and southern zones. Heights will begin to fall through the day Sunday but the enhanced mixing will most likely compensate, resulting in one more warm day before a more substancial cooling follows for Monday and Tuesday as the low creeps inland. Precipitation chances continue to favor the Sierra and southern Great Basin on Monday and Tuesday, though a few instability driven showers are possible further south Tuesday and Wednesday as the cold core aloft moves through the deserts.
Temperatures will drop sharply as the low moves through the region, with afternoon highs topping out a few degrees below normal. High pressure will slowly build back into the region mid- late week though the weather pattern looks to remain active as we finish the first week of May.
