.SYNOPSIS...Temperatures will peak on Sunday, when an Extreme Heat
Warning is in effect for lower elevations of southeastern
California, southern Nevada, and northwestern Arizona. Expect breezy-
to-gusty southwesterly winds each afternoon through the forecast
period, with strongest speeds expected on Monday. Temperatures will
cool off slightly through the start of the work week, but will peak
once again midweek.

&&

.UPDATE...Current forecast on track as high pressure over the region
will bring dry conditions, above normal temperatures, and breezy
afternoon southwest winds. No updates planned.

&&

.SHORT TERM...Today and Sunday.

A high pressure over the southeastern Pacific Ocean / northern
Mexico will increase heights across the Desert Southwest, resulting
in temperatures peaking on Sunday at 8 to 12 degrees above seasonal
normals. "Major" HeatRisk is spreading across desert valley
locations of our forecast area, with widespread "Moderate"
elsewhere. Extreme Heat Warning in effect on Sunday (Father`s Day)
for valley locations of southeastern California, southern Nevada,
and northwestern Arizona. This warning includes Death Valley
National Park, western San Bernardino County, far southern Nye
County, lower elevations of Clark County including Las Vegas,
southern Mohave County, and the Colorado River Valley including the
Lake Mead National Recreation Area. If planning to spend time
outdoors this weekend, avoid the hottest parts of the day, bring
plenty of water, and wear sunscreen.

Meanwhile, a dry southwesterly flow aloft continues as the region
remains sandwiched between a closed area of low pressure in the Gulf
of Alaska and the aforementioned ridge of high pressure. As such,
expect breezy southwest winds each afternoon through the weekend.
This will result in increased fire concerns across the forecast
area, so be aware of this if recreating outside with sparks or
flames.

.LONG TERM...Monday through Saturday.

The ridge is suppressed early next week as an upper level trough
moves through the western United States. Breezy southwesterly winds
should pick up across most of the forecast area in response on
Monday. The strongest winds should be in western San Bernardino
County, where there the probability of wind gusts over 40 mph (Wind
Advisory criteria) is over 60 percent. Will continue to monitor to
see if wind headlines become necessary, but for now it appears that
the strongest winds will remain over high terrain. However,
widespread dry and breezy conditions does bring increased fire
weather concerns across the forecast area. Temperatures should
decrease a few degrees by Tuesday as heights aloft fall.

Ridging quickly rebuilds as the trough moves east. Temperatures
increase a few degrees and dry conditions persist. Another trough
begins to approach the West Coast towards the end of next week,
which may bring additional gusty winds.

For the rest of southern Nevada, northwest Arizona and southeast

winds will settle out of the south and southwest this morning,
becoming gusty through this afternoon. Gusts to around 20KT will
be common, with stronger westerly winds across the Western Mojave
Desert, including KDAG. The exception will be across the Lower
Colorado River Valley, where gusts are not expected. VFR
