.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 18Z Forecast Package...Light
winds under 8KT are expected through the TAF period. Northeast winds
around 5-7KT will gradually shift the southeast after 21Z. Typical
southwest winds return tonight around sunset. Clear skies will
persist through the period. Very warm temperatures are expected
through the weekend as high temperatures climb over 90 degrees each
afternoon. There is a 20% chance temperatures reach or exceed 100
degrees on Friday, then a 10% chance on Saturday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 18Z Forecast Package...AT KIFP, breezy north
winds up to 20KT will continue into this afternoon, but gradually
diminish this afternoon with speeds around 10KT or less. Elsewhere,
