Marine Weather and Tide Forecast for Pahrump, NV

DISCUSSION
through Wednesday.

Today's temperatures remain 5 to 10 degrees above normal for mid- June. For Las Vegas, this means highs in the mid to upper 100s.
Temperatures should gradually decline to near normal values by this weekend as an incoming shortwave pushes high pressure east and heights aloft fall. Along with cooling temperatures, the shortwave will bring breezy southerly to southwesterly winds to the area on Friday. The strongest wind gusts should generally be in the 25 to 35 mph range, but a few gusts up to 40 mph cannot be ruled out in western San Bernardino County. Increased winds combined with low afternoon RH and dry fuels bring elevated fire weather conditions to much of the area - see the FIRE WEATHER section below for more details. A weaker secondary shortwave will help maintain breezy conditions and near normal temperatures on Saturday.

Another ridge of high pressure builds over the southwestern United States again next week. Afternoon high temperatures become 5 to 10 degrees above normal by Wednesday and Major (Level 3 of 4) Heat Risk returns to valleys across the Mojave Desert. This level of heat will affect anyone without sufficient cooling or hydration, especially those spending time outdoors. Las Vegas has a 50 percent chance of reaching 110 degrees on Wednesday afternoon.

AVIATION
For Harry Reid
For the 12Z Forecast Package
Southerly to southwesterly winds around 10KT will continue through the morning and into the early afternoon. There is the potential for a brief lull shortly after sunrise when winds may decrease below 8 knots for a few hours. Winds will increase to 12 to 15 knots with intermittent gusts of 20 to 25 knots from mid-afternoon through sunset, with wind directions varying between 160 and 190 degrees true. Winds will then shift to the southwest after sunset, although speeds are expected to remain in the 10 to 13 knot range through much of the night. Wildfire smoke from fires north of the Las Vegas Valley will continue drifting over the area, with SCT to BKN layers around 15 to 20kft AGL expected due to the lofted smoke. The greatest impact is expected along the northeast approach and departure corridors. Otherwise, VFR conditions will prevail through the TAF period. Temperatures will exceed 100F between 18Z and 04Z, peaking near 107F around 00Z.

For the rest of southern Nevada, northwest Arizona and southeast California
For the 12Z Forecast Package
Southerly to southwesterly winds will continue across much of the region through most of the morning. Winds will then turn more southerly to southeasterly this afternoon, with occasional gusts to around 25 knots possible in most areas. One exception will be at KBIH in the northern Owens Valley, where winds will generally follow typical daily directional patterns through the forecast period.
Additionally, winds across the western Mojave Desert, including KDAG, will remain gusty out of the west through mid-afternoon before briefly becoming light and shifting to the northeast for a few hours. Westerly winds will return by evening, with gusts up to 35 knots possible. VFR conditions will prevail at area terminals.
However, lofted smoke from wildfires over the southern Great Basin may result in SCT to BKN layers around 15 to 25kft AGL near and north of the Las Vegas Valley.

FIRE WEATHER
Winds increase out of the south to southwest on Friday as a shortwave moves into the western United States.
Sustained winds between 20 and 25 mph along with gusts upwards of 35 mph develop by the late morning, lasting into the evening.
These winds combined with minimum humidity in the 5 to 15 percent range and dry fuels create Elevated fire weather conditions across southern Nevada and northwestern Arizona and a Fire Weather Watch has been issued.
