Marine Weather and Tide Forecast for Parker Strip, AZ

DISCUSSION
Today through Monday.

Current satellite imagery shows an area of low pressure spinning off the Oregon coast. This feature will bring several notable changes to the weather pattern as it tracks inland today. The primary impact will be an increase in southerly to southwesterly winds. A High Wind Warning will go into effect for Esmeralda and Nye Counties along with Death Valley National Park at 10 AM PDT today, where there is a 70 to 90 percent probability of gusts over 58 mph, especially over mountain ranges and high terrain. Gusts will reach 40 mph across much of the remainder of the southern Great Basin and Mojave Desert, and Wind Advisories will go into effect today for these areas as well. Gusty southwesterly winds should continue in the western Mojave Desert near Barstow on Wednesday, but they appear too borderline to warrant a Wind Advisory and no headlines will be issued at this time. A cold front passage associated with this system will lower temperatures about 10 degrees between today and tomorrow, bringing highs back below seasonal normals. Lastly, there is a 30 to 50 percent probability of precipitation in the southern Great Basin and Eastern Sierra today and tonight. The greatest chances are over high terrain. Precipitation totals should be light (less than one tenth of an inch) as most moisture is blocked by the Sierra Nevada. However, cooler air will bring snow levels down to between 5000 and 6000 feet, and over one foot of snow is possible over the Sierra crest above 10,000 feet in elevation.

A zonal pattern forms aloft as the the low pressure system tracks east into the Great Plains later this week. Temperatures increase several degrees and highs should be within a few degrees of normal for late April. Another system could reach the forecast area over the weekend, but discrepancy remains between models regarding depth, speed, and position of the low as it moves across the region.
Increased winds, cooler temperatures, and precipitation are all within the realm of possibility.
