Area forecast discussion
National Weather Service Las Vegas Nevada
300 am PDT Mon Oct 14 2019

Synopsis...dry and seasonable weather can be expected through
the week followed by a cooling trend late in the weekend. Breezy
conditions will develop Thursday then again Saturday night and
Sunday as fast moving troughs brush the region.
&&

Discussion...today through next Monday.

No significant weather impacts are expected through the forecast
period. Some cirrus clouds over Inyo County and south central Nevada
were associated with a weak upper level circulation over central
California this morning, but that will be the only noticeable effect
of this feature as it works its way down over southeast California
and across Arizona by early Tuesday. A ridge near the West Coast
will then migrate inland through Wednesday ahead of a shortwave
trough which will quickly move across the Great Basin late Thursday
leading to some breezy conditions but wind gusts should generally be
less than 30 mph.

Temps will lower about 5 degrees Friday as broad troughing develops
over the west going into the weekend allowing a deeper shortwave to
dig over the Great Basin and intermountain region Saturday night and
Sunday. Model ensembles depict a deep trough carving out over The
Four Corners region which would lead to gusty north winds Sunday
into Monday for our forecast area but wind gusts look to be
generally 25 to 35 mph as high temps drop an additional 10 degrees or
so.
&&

Aviation...for McCarran...light and variable winds will continue
this morning before shifting to more of an easterly direction late
morning/early afternoon. Few above 16 kft expected today with mostly
clear skies expected tonight.

For the rest of southern Nevada, northwest Arizona and southeast
California...light winds generally under 15 knots following typical
wind patterns. No operationally significant clouds expected through
tonight.

&&

Spotter information statement...spotters are encouraged to report
any significant weather or impacts according to Standard operating
procedures.
