Daggett, California

... Sin city sizzled this July...
... Warmest month ever in Las Vegas...

Most of the following information is final for the month. A more
detailed area monthly weather summary will be issued Sunday evening
by the National Weather Service office in Las Vegas.

Well if you felt you sweltered this month more than usual... you are
correct. July 2010 will go down as the warmest month ever in Las
Vegas with records dating back to 1937. At the official climate
station at McCarran International Airport the average monthly
temperature was 96.2 degrees. Unless any drop in the low temperature
occurs through 1 am PDT tonight this average value is not subject to
change. This would make July 2010 the warmest month ever in Las
Vegas and thus the warmest July ever. The previous record for the
warmest month ever and warmest July ever was held by July 2007 with
an average temperature of 95.4 degrees. The average temperature this
July was exactly 5.0 degrees above normal.

The warmth this past month was largely due to warm low temperatures
that were prevelant in the later two-thirds of the month. The
average low temperature this month was 85.7 degrees which sets a
record for the warmest ever for any month. The previous record was
83.8 set in July 2006. There were also a record 6 days with lows of
at least 90 degrees or better... including a stretch of 5 in a row.
The previous record for the most days with a low temperature of at
least 90 degrees or better was 5 set in 2005.

However... high temperatures were also above normal this month. The
average monthly high temperature ties for the 13th warmest ever at
106.6 degrees tied with 2003. The total number of days this month
with a triple digit high temperature in Las Vegas was 31. This ties
the all-time record for July of 31 days set in 1988... 1971... 1963
and 1944. Counting the 4 augusts that have had every day reach the
triple digits only nine months ever in Las Vegas dating back to 1931
have had every single day in the month reach into the triple
digits. July 1988 was the last time a month in Las Vegas saw the
high reach the triple digits on every single day of the month.

The low temperature today at McCarran International Airport so far
today has been 88 degrees. This breaks the old record high minimum
temperature - or warmest low temperature ever - for the date of 86
set in 1995.

The above information is preliminary and is subject to a final
review and certification by the National climatic data center.
