.KEY MESSAGES...

* Heat headlines remain in effect as an unprecedented March
  heatwave continues into next week.

&&

.DISCUSSION...through Wednesday.

All of the monthly records that were broken yesterday will be
overwritten today and tomorrow as temperatures continue to climb.
Temperatures across the region will peak on Friday, with a relative
"cool down" over the weekend as the ridge weakens. Even with this
relative decrease in temperatures over the weekend into early next
week, we will still be around 20 degrees hotter than normal. Given
the prolonged nature of these record breaking temperatures, the Heat
Advisory for the southern Great Basin and Extreme Heat Warning for
the Mojave Desert will remain in effect until Saturday and Sunday,
respectively. The ridge of high pressure will rebound next week,
with hotter than normal temperatures looking to stick around for at
least another week.

.AVIATION...For Harry Reid...For the 00Z Forecast Package...Light
winds under 8 knots will continue through Friday. Typical southwest
winds return after sunset, followed by northeast to east winds
Friday afternoon. Very warm temperatures are expected through the
weekend with afternoon highs climbing above 90 degrees each day.
There is a 20 percent chance temperatures reach or exceed 100
degrees Friday, then a 10 percent chance Saturday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 00Z Forecast Package...Gusty northerly winds
will continue down the Colorado River Valley for a few more hours
before decreasing to less than 10 knots by mid-evening. Elsewhere,
light winds under 10 knots will follow typical diurnal directional
patterns through Friday. Clear skies will persist through the period.
