.DISCUSSION...Today through Saturday.

Isolated showers and thunderstorms will be possible this afternoon
across Mohave County, as the trough over the Pacific Northwest sags
just far enough south to provide instability and shear to aid in
storm development. Mesoanalysis reveals over 1,000 J/kg of CAPE
across the eastern two thirds of Mohave County. There is a north-
south oriented precipitable water (PW) gradient across Mohave
County, with PWs of 1.0 inches in northern Mohave County increasing
to 1.5 inches as you go south. Given this anomalous moisture,
isolated flash flooding will be possible with heavy storms. Outflow
winds will be an additional threat given the drier low-levels of the
atmosphere. Storms will dissipate in the evening after sunset. Low
chances for isolated convection will linger through the week for
portions of Mohave County.

As the aforementioned trough over the Pacific Northwest continues to
deepen, it will push last week`s ridge eastward. This will result in
breezy southerly to southwesterly winds across the region due to the
enhanced pressure gradient. Wind gusts will peak in the 25 to 35 mph
range this afternoon, decreasing during the evening and overnight
hours. Troughiness will linger across the region through the week,
with breezy southerly to southwesterly winds picking up each
afternoon and decreasing after sunset each day. High temperatures
will fall back to near average (90s to low 100s). Low temperatures,
however, will only see some slight reduction, staying around 5
degrees above average. Temperatures look to gradually increase again
by the end of the work week as pressure begins to increase.
