Marine Weather and Tide Forecast for Goldfield, NV

DISCUSSION
Through Monday.

Expect one more day of elevated to critical fire weather conditions as hot, dry, and windy conditions continue. The trough responsible for strong southwesterly winds is shifting east, meaning winds will be relatively lighter today compared to yesterday in southern Nevada. The position of the trough allows for gusty winds to continue in northwestern Arizona, making it the area of greatest concern for today. See the FIRE WEATHER discussion below for more details. Fire weather conditions will improve by Wednesday as the trough lifts out of the area and winds subside areawide.

High pressure builds over the western United States starting midweek. Rising heights aloft and increasing surface temperatures will make heat the main forecast concern through the weekend.
Temperatures peak on Saturday and Sunday with highs 5 to 10 degrees above normal for mid-June. The increase in daytime highs as well as overnight lows brings widespread Moderate (Level 2 of 4) Heat Risk to the region with areas of Major (Level 3 of 4) Heat Risk in many desert valleys including Death Valley, the Colorado River Valley, and the Las Vegas Valley between Friday and Sunday. This level of heat will affect anyone without access to sufficient cooling and hydration, especially those spending time outdoors. However, ensembles are also highlighting a potential tropical moisture push from the Gulf of California into the Desert Southwest over the weekend, which may bring cloud cover and hinder the increase in temperatures. Light rainfall and isolated thunderstorms cannot be ruled out either, particularly along high terrain. Will continue to monitor this moisture trend throughout the week.

For the rest of southern Nevada, northwest Arizona and southeast California
For the 06Z Forecast Package
Gusty south-southwest winds will return to Las Vegas Valley and Colorado River Valley TAF sites Tuesday afternoon, with gust speeds peaking between 25 and 30 kts. Light northwesterly winds expected at KBIH with speeds briefly picking up to 8 to 12 kts around 00Z. Gusty west winds at KDAG will be elevated around 30 kts overnight and around 20 kts in the afternoon. No operationally significant cloud cover through the TAF period.

FIRE WEATHER
The trough responsible for gusty southwesterly winds shifts to the east today and the main focus for wind will turn to northwestern Arizona. Winds gusting to 40 mph combined with minimum humidity in the 5 to 15 percent range will yield elevated to critical fire weather conditions. Any fires that develop will likely spread rapidly. Therefore, the Red Flag Warning will remain in effect for all northwestern Arizona zones and the Nevada side of the Colorado River Valley through this evening. Conditions are expected to improve Wednesday onward as the trough exits and winds weaken.
