Marine Weather and Tide Forecast for Goldfield, NV

DISCUSSION
through Halloween.

Water vapor imagery shows a trough overhead with a vort max over southern CA in the process of pinching off into a closed low. Behind the shortwave, gusty north winds are currently pushing through the southern Great Basin and into the northern Mojave Desert. These will continue advance southward, encompassing most of the CWA by sunrise.
Strongest winds anticipated in Death Valley and the southern Owens Valley where gusts of 40-50 mph are possible through the morning hours. Elsewhere, expecting gusts generally 20-35 mph, weakening during the 2nd half of the day. The formation of the closed low will cause the system to slowly exit the region, lingering over northwestern AZ this afternoon. The cold air aloft, residual moisture, and daytime heating should drive isolated to scattered showers and maybe even a few storms over eastern Mohave County (20- 40%), with lower chances (10-20%) over southeastern NV and the Colorado River Valley. Can't completely rule out an isolated instance of flash flooding in eastern Mohave County, but odds are 5% at best.

Our low finally exits on Sunday, leaving us in a zonal pattern for a few days before transitioning to southwesterly flow later in the week. From Sunday - Thursday, the forecast calls for seasonable temperatures, light breezes, and dry conditions. Late in the week, ensemble guidance shows an energized subtropical jet trying to push moisture into the southwestern US. Cluster analysis shows several variations of offshore troughing during this time, so there remains a fair amount of uncertainty, but there appears to be a good signal for the existence of an offshore trough and southwesterly flow over us. Should this come to fruition, we should see an increase in southwest winds and low to moderate (10-50%) precipitation chances around Halloween weekend.
