.KEY MESSAGES...

* Anomalous, early-season heat will continue through early next week.

* A pattern shift should bring near normal temperatures by the
  middle of next week.

.DISCUSSION...through Wednesday.

Once again, all climate sites across the forecast area reported
daily record high temperatures yesterday. Not only did Las Vegas
achieve a new longest streak of record high temperatures (eight
days: March 18-25, 2026), but a monthly record high temperature for
March was set with a high of 98 degrees. A weak and compact area of
low pressure will move through the area along the wider ridging
pattern today, which will bring high cloud cover and decrease
temperatures by a few degrees. Las Vegas has a 50 percent
probability of reaching 93 degrees, the daily high temperature
record for March 26. The number of consecutive daily high
temperature records for Las Vegas would rise to nine if this occurs.
The upper level ridge will remain in place and above normal
temperatures persist through the weekend, breaking even more daily
temperature records. See the CLIMATE section for more details.

Relief from the heat appears on the horizon as an upper level trough
approaches the Pacific Coast midweek next week. Highs should return
to near seasonal normals, but some uncertainty remains regarding the
exact timing and depth of the trough.

.AVIATION...For Harry Reid...For the 12Z Forecast Package...Light
southwest winds early this morning will turn northeast by midday.
Winds are expected to remain light at less than 8 knots into the
early evening before turning back to the southwest around sunset.
There is some disagreement in the models for Thursday night, with a
subset of guidance pushing breezy northeast winds into the valley
around midnight. Given the uncertainty of this scenario, these
breezy winds have not been included in the TAFs. If winds do
develop, speeds of 10 to 13 knots would be possible after 07Z. VFR
conditions will prevail through Friday, with only a few high clouds
with bases AOA 20kft AGL during the day.


For the rest of southern Nevada, northwest Arizona and southeast
California...For the 12Z Forecast Package... Winds will remain light
in most areas Thursday, with speeds generally 12 knots or less into
Friday morning. VFR conditions will prevail through the TAF period,
with only a few SCT to BKN clouds across the Sierra and southern
Nevada expected today.
