[REMARKS]

FEBRUARY 2010 WAS FAIRLY WARM WITH AN AVERAGE TEMPERATURE FOR THE
MONTH OF 40.8 DEGREES. THIS IS 2.3 DEGREES ABOVE THE NORMAL AVERAGE
TEMPERATURE OF 38.5 DEGREES. ON ALL BUT FOUR DAYS DURING FEBRUARY
THE AVERAGE DAILY TEMPERATURE WAS WITHIN PLUS OR MINUS 10 DEGREES OF
NORMAL FOR EACH DAY. THE EXTREMES INCLUDED FEBRUARY 5TH WHICH WAS 11
DEGREES ABOVE NORMAL FOR THE DATE...AND FEBRUARY 21ST WHICH WAS 14
DEGREES BELOW NORMAL.

FEBRUARY WAS RELATIVELY WET WITH 2.18 INCHES OF PRECIPITATION BEING
REPORTED.  THIS MAKES FEBRUARY 2010 THE 17TH WETTEST FEBRUARY AT
RENO IN THE PAST 140 YEARS (SINCE PRECIPITATION RECORDS BEGAN AT
RENO IN 1870).  THIS IS 1.12 INCHES ABOVE NORMAL FOR FEBRUARY.  OF
THE 2.18 INCHES OF PRECIPITATION FOR THE MONTH NEARLY HALF...1.06
INCHES...FELL OVER A PERIOD OF JUST TWO DAYS ON FEBRUARY 20TH AND
21ST.

THIS 1.06 INCHES OF PRECIPITATION COINCIDED WITH A SNOWSTORM THAT
MOVED THROUGH THE REGION ON THE 20TH AND 21ST. THIS WAS A RELATIVELY
UNIQUE SNOWSTORM IN THAT THE COLD FRONT ASSOCIATED WITH IT STALLED
OVER THE NORTH CENTRAL SIERRA AND WESTERN NEVADA. THE SNOWBAND
ASSOCIATED WITH THE COLD FRONT REMAINED OVER THE RENO AREA FOR MUCH
OF THE 20TH AND 21ST.

RECORD SNOWFALL AMOUNTS FELL ON BOTH DATES AT RENO. A RECORD 4.2
INCHES OF SNOW FELL ON FEBRUARY 20TH AND A RECORD 10.9 INCHES OF
SNOW FELL ON THE 21ST. THIS 10.9 INCHES OF SNOW MAKES FEBRUARY 21
2010 TIED FOR 16TH ON THE LIST OF LARGEST CALENDAR-DAY SNOWFALL
TOTALS IN RENO SINCE 1897.  THE TWO-DAY TOTAL OF 15.1 INCHES OF
SNOWFALL MADE THIS SNOWSTORM TIED FOR 22ND PLACE IN THE LIST OF
LARGEST SNOWSTORMS TO AFFECT THE RENO AREA SINCE 1897.

A TOTAL OF 16.1 INCHES OF FROZEN PRECIPITATION FELL AT RENO DURING
FEBRUARY.  THIS INCLUDES THE 15.1 INCHES OF SNOW WHICH FELL ON THE
20TH AND 21ST...AND 1.0 INCH OF HAIL WHICH FELL ON THE 27TH.  THIS
16.1 INCHES OF FROZEN PRECIPITATION MAKES FEBRUARY 2010 THE 8TH
SNOWIEST FEBRUARY AT RENO IN 110 YEARS (SINCE 1900).

FEBRUARY WAS NOT AS WINDY AS JANUARY 2010 WAS.  THE AVERAGE DAILY
WIND SPEED DURING FEBRUARY WAS 3.4 MPH.  THE HIGHEST WINDS WERE
RECORDED ON THE 26TH WITH AN AVERAGE WIND SPEED OF 11.9 MPH FOR THE
DAY WITH THE STRONGEST WIND SPEED REACHING 43 MPH OUT OF THE SOUTH.
THE HIGHEST WIND GUST OF 53 MPH WAS ALSO RECORDED ON FEBRUARY 26TH.
