  in increasing thunderstorm chances for portions of the area.

.DISCUSSION...through next Thursday.

Weather over the next few days will remain relatively benign as a
ridge of high pressure slowly nudges into the region. These slowly
increasing 500 mb heights will allow for our gradual warming trend
to continue through early next week. Warmer than normal temperatures
will return to southern Nevada, northwestern Arizona, and
southeastern California as we head into the weekend, resulting in
widespread Moderate (Level 2 of 4) HeatRisk. Moderate HeatRisk means
that this level of heat will impact heat sensitive individuals,
individuals that have not acclimated to the heat, and those without
access to effective cooling and/or adequate hydration. Temperatures
across the region will peak on Monday, with a few patches of Major
(Level 3 of 4) HeatRisk popping up in the Colorado River Valley,
Golden Valley, and the lower elevations of the Big Sandy Wash.

While the ridge of high pressure slowly pushes into the area, a
trough will develop off the coast of California over the weekend.
This set up will result in southerly flow across the region next
week, which will result in increasing moisture across Mohave County
that will then spill into southeastern California and southern
Nevada. Confidence regarding next week`s increase in moisture is
high, however the exact details regarding locations of individual
storms and precipitation amounts remain blurry due to interensemble
variability. Precipitation totals will be dependent on how much we
see moisture increase, which will be dependent on the orientation of
the trough relative to the ridge as it pushes into the area. With so
many moving parts, make sure to stay tuned to the forecast as it
continues to evolve.
