Two people died in southern Nevada of heat-related causes.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jun 30, 8:38 PM PST, 3 hours 22 minutes earlier. Its key messages:

  • * Hot temperatures continue, peaking today and Tuesday and slowly moderating thereafter. * Increasing moisture will result in a return of thunderstorm chances, first across Mohave County on Tuesday, then expanding across southern Nevada and eastern San Bernardino County through Wednesday. Storm chances may linger across northwestern Arizona through Thursday.

  Wednesday. Storm chances may linger across northwestern Arizona

.DISCUSSION...

This afternoon, highs are well on their way to topping out around 3
to 7 degrees above normal with current temperatures in the mid 90s
and lower 100s across lower elevations, and 80s in the mountains.
Per latest water vapor imagery and 500hPa RUC analysis, a
negatively-tilted ridge remains anchored over the Four Corners
Region, with an approaching trough to the west off of the Central
California Coast that will gradually translate eastward the next
several days. Decreasing thicknesses with this trough as well as
increasing moisture will result in a slow moderation of
temperatures, with highs Tuesday similar to today, but gradually
cooling down and topping out closer to normal by the end of the week
and into this weekend. Fortunately, HeatRisk largely remains in the
Minor to Moderate range, precluding the need for any heat-related
headlines, though those spending time outdoors will still need to
ensure they stay hydrated and as cool as possible.

Ahead of the approaching trough, monsoonal moisture will continue
increasing over the region. This increase in moisture is already
underway today, with precipitable water (PWAT) values over southern
reaches of the forecast area already gradually working toward 100
percent of normal. This increase will be more substantial Tuesday
and especially on Wednesday, as PWATs increase to around 125 to 150
percent of normal per latest ensemble guidance, focused particularly
across southern Nevada and northwestern Arizona. This moisture,
coincident with the approaching trough to the west and its
associated ascent will yield increasing storm chances. Storm chances
begin ramping up across Mohave County Tuesday afternoon and evening,
gradually expanding northward and westward through Wednesday, with
current expectations for storm potential to peak Wednesday afternoon
into Wednesday evening. Storm chances look to linger into Thursday,
particularly across portions of Mohave County, though the timing of
the aforementioned trough will make a difference as it ushers in
drier air, shunting moisture and storm chances eastward. In its
wake, a return to dry and breezy conditions is expected for the end
of the week through the upcoming weekend.

.AVIATION...For Harry Reid...For the 06Z Forecast
Package...Southwesterly winds under 10 knots should persist
through the night before variable winds develop tomorrow morning.
Another round of gusty south-southwest winds arrives in the
afternoon and mid level clouds should start to move into the area
during that time. Outflow from convection in the region may reach
the Las Vegas Valley in the late afternoon or early evening, but
confidence is low at this time. Any outflows that reach the
terminal may cause temporary changes in wind direction or speed.
Temperatures should fall to less than 100 degrees by 04Z,
increasing to over 100 degrees between 18Z and 04Z tomorrow.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 06Z Forecast Package...Breezy westerly winds
persist through the night in the western Mojave Desert including
KDAG. Light winds are expected elsewhere. Tomorrow's winds should be
similar to today's, with increasing southerly to southwesterly winds
at most locations in the afternoon. Convection is likely in the
region tomorrow afternoon and evening. Outflow winds from storms
over high terrain in northwestern Arizona may reach the Colorado
River Valley including KEED and KIFP by the evening. Outflow from
isolated storms may also reach terminals in other parts of the
Mojave Desert including the Las Vegas Valley in the afternoon and
evening, but confidence is low at this time.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
