Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Las Vegas Nevada
941 am PST Thursday Mar 5 2015
Synopsis...a ridge of high pressure along the West Coast will bring
dry and mild weather conditions to the area through early next week.
Update...winds have picked up in the Colorado River valley in the
Laughlin-Bullhead City area from the north. We will be close to lake
Wind Advisory criteria there but it is such a small area that no
headlines will be issued. Otherwise the forecast looks in good shape.
Aviation...for McCarran...winds will be 8 kts or less and trend
toward typical diurnal wind shifts under a relatively clear sky.
For the rest of southern Nevada...northwest Arizona...and southeast
California...along the Colorado River near kifp and keed northerly
winds will persist in the 10-20 knots range with gusts to 25 kts.
Elsewhere...light winds favoring typical diurnal wind patterns are
expected. A realtively clear sky is forecast through Friday

Short term...through Saturday night.
Very tranquil weather is expected through the short term period as
high pressure strengthens over the region. This expanding bubble of
high pressure will be centered over northern California and western
Nevada and will allow for temperatures to gradually climb a few
degrees each day under generally light winds and cloudless skies.
By Friday afternoon high temperatures are expected to creep above
normal for the first time in nearly a week...with even warmer
temperatures on tap for Saturday.
Long term...Sunday through Wednesday.
A continuation of dry and mild weather can be expected over the
region early next week as a ridge with its axis near the West Coast
holds Sunday and Monday then slowly breaks down and moves inland
Tuesday. This will allow a zonal flow to develop by the middle of
the week with the medium range models indicating weak short waves
and some generally diffuse Pacific moisture moving across the
region. It appears this will primarily bring increasing cloud cover
but cannot rule out some light precipitation in the southern Sierra.
Elsewhere...the probability of precipitation is too low to mention for now.
Temperatures will remain mild through the period with highs in Las
Vegas in the 75-80 degree range.
Spotter information statement...spotter activation is not expected
through the weekend.
