.KEY MESSAGES...

* Unsettled and unseasonably-cool conditions linger today.

* Calmer and warmer weather returns over the weekend and next week.

.DISCUSSION...through Thursday.

As mentioned in the previous discussion, the low pressure system has
begun to lift to the northeast, resulting in isolated-to-scattered
showers and thunderstorms popping up over southeastern Nevada and
northwestern Arizona. Locally, here in Las Vegas, the western
portions of the valley saw some light rain as showers drifted off
the Spring Mountains and into the valley where they eventually
weakened and dissipated. This light rain should be the extent of
precipitation for the Las Vegas area as we find ourselves behind the
trough axis. As the low continues to slowly lift northeast and exit
the area, showers and thunderstorms will continue in Mohave and
Lincoln Counties this afternoon with convection quickly dissipating
after sunset. Variable wind gusts around 30 to 40 mph, lightning,
and light-to-moderate rain will be threats with these storms this
afternoon.

Once this low pressure system clears out of the area, we will see
500 mb heights rebound over the weekend. These increasing heights
will allow for temperatures to recover over the weekend with warmer
than normal temperatures returning next week. Dry and calm
conditions will accompany these above normal temperatures through
much of next week.
