.DISCUSSION...Today through Thursday.

Las Vegas had a high of 111 degrees yesterday, the first 110+ degree
high since August of last year. High pressure over the region will
maintain afternoon high temperatures 6 to 8 degrees above-normal
through Sunday. Hot daytime temperatures combined with warm
overnight low temperatures will result in widespread Moderate
(Level 2 of 4) with pockets of Major (Level 3 of 4) Heat Risk for
most locations. A combination of dry and breezy conditions also
prompt elevated fire weather conditions in parts of southern
Nevada and northwestern Arizona today.

The high pressure becomes centered over the Four Corners over the
weekend, allowing for moist monsoonal flow into the Desert
Southwest. First, convection over the Mogollon Rim may produce
outflow winds that could reach Mohave County on Saturday evening.
PWATs over one inch spread into areas along and south of Interstate
15 on Sunday, then into the remainder of southern Nevada and
southeastern California on Monday onward. PoPs favor areas of
high terrain as orographic lift assists in storm formation. Gusty
outflow winds and dry lightning appear to be the primary threats
for at least the first few days of the week as forecast soundings
display inverted-V patterns with moisture aloft and drier air near
the surface. The high generally remains in place throughout the
week and there is increasing confidence in convection each day.
