Marine Weather and Tide Forecast for Dyer, NV

DISCUSSION
Today through Thursday.

Gusty north winds will continue to sweep southward across the forecast area as a cold front pushes through the Desert Southwest.
Speeds will be greatest immediately following the frontal passage, then gradually decreasing thereafter. As of 2:30 AM PDT, the front has pushed through the Las Vegas Valley and is nearly out of southern Nevada, approaching the Colorado River Valley. Peak wind gusts so far include 72 mph at Tikaboo Peak, 58 mph at Desert Rock Airport, 56 mph at Harry Reid Airport, and 55 mph at North Las Vegas Airport. Winds will be strongest in the higher terrain as well as along north-south oriented valleys, such as the Colorado River Valley. As a result, expect very dangerous boating conditions, with wave heights between 2 and 4 feet on Lake Mead, Lake Mohave, and Lake Havasu. The Wind Advisory will continue for the southern Great Basin and Las Vegas Valley until 5 AM... for the Mojave Desert until 11 AM... and for the lower Colorado River Valley until 5 PM. Due to a reconfiguration of our local forecast zones, we are now able to expire the Wind Advisory for Lake Mead at 11 AM ahead of the Lake Mohave 5 PM. Otherwise, no changes made to the existing headlines.
Expect a drop in temperatures of 10 to 14 degrees this afternoon compared to yesterday afternoon.

A ridge of high pressure returns to the region over the weekend into the start of the next work week, which will allow temperatures to climb back above-normal. Thereafter, ensemble model data indicates the approach of a closed low digging down from the Gulf of Alaska and eventually pushing into the Desert Southwest. This system continues to slow down with each model run. As a result, the weekend ridge stays in place a bit longer, allowing temperatures to peak at near 10 degrees above-normal on Monday. Midweek, gusty winds, chances of precipitation, and cooler temperatures return as the closed low moves inland. Will continue to work out the details regarding strength, position, and timing as we move through the weekend.
