.KEY MESSAGES...

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

&&

.DISCUSSION...through Thursday.

The forecast remains largely unchanged thanks to a somewhat
malleable ridge that models show holding over the southwestern US.
Expecting temperatures to peak today, then subtly cool over the
weekend as a weak system passes by. This feature brings breezy
southwest winds and some high clouds, but that`s about it. Ensemble
guidance then has the ridge restrengthen next week, causing
temperatures to rise a few degrees. Exactly how hot it gets will
depend on the strength of the ridge and extent of mixing.
Regardless, temperatures are going to remain well above normal for
mid/late March as this historic heatwave continues. Here in Vegas,
there is at least a 75% chance of reaching 90 degrees each day
through Thursday. Should this materialize, it would put us at 9 days
of 90+ degrees this March. For reference, we had just 1 March day of
90+ from 1937 (when records began) to 2003, and 12 March days of 90+
from 2004 to 2025.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light
winds under 8KT are expected through the period. Winds today could
be light from the east winds late morning that then shift southeast
after 21Z, or winds will be light and variable under 5KT. Typical
south to 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 10% chance temperatures reach or exceed 100
degrees today and on Saturday.

For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package...Light winds are expected
overnight. Breezy north winds will develop around KIFP gusts up to
20KT later this morning, however these elevated winds in the
Colorado River Valley should remain isolated to this area and will
diminish after 21Z. In addition, breezy south to southeast winds
will develop in the Owens Valley with a 20% chance for gusts over
20KT in the afternoon. Any gusts that develop in the Owens Valley
