.KEY MESSAGES...

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

&&

.DISCUSSION...through Wednesday.

We saw monthly high temperature records set at 5 of our 7 climate
sites yesterday. Expect these to be rewritten today, and again on
Friday. The sites that didn`t break their March records (Bishop and
Death Valley) are likely to today and/or Friday. At the peak of the
heatwave, temperatures will approach all-time April records.
Temperatures cool slightly Sunday and Monday as a weak shortwave
passes by, but models show the ridge strengthening again next week.
Basically, temperatures are going to run well above normal for at
least the next 7 days, if not longer. We`re running out of ways to
describe how anomalous this heat is, but I`ll try a new one. Using
extended temperature forecasts for Las Vegas from the NBM and raw
ensemble data, this March has the potential to finish with an
average temperature of 71.5-72 degrees. Not only would this demolish
the old March record of 66.7 degrees, but if we were to pretend it
was April, it would rank as the third hottest April on record.
Obviously, there`s still a fair amount of uncertainty in how warm
the last week of March will be given it`s over 7 days away, but it`s
very likely (80%) to at least run above normal.

California...For the 12Z Forecast Package...Breezy north winds will
develop around KIFP gusts up to 20KT develop after later this
