Area Forecast Discussion
National Weather Service Las Vegas NV
811 PM PDT Tue Jun 27 2017

.SYNOPSIS...Dry conditions will persist through the coming weekend
with temperatures near or slightly above normal. Areas of breezy
winds can be expected each afternoon.

.UPDATE...Mart wildfire near Highland CA in the San Bernardino County
producing a smoke plume that is drifting east over the Morongo Basin
this evening. Depending on just how active the fire remains
tonight/Wednesday a favorable westerly wind direction should keep
some drifting east across southern San Bernardino County. Not sure
how much smoke may surface in the Morongo Basin as winds weaken but
decided to include a mention of patchy smoke through Wednesday. No
other updates needed.

.PREV DISCUSSION...254 PM PDT Tue Jun 27 2017
.SHORT TERM...Tonight through Friday.

A dry west to northwest flow can be expected over the region through
Friday with temperatures near or slightly above normal. A shortwave
trough moving into northeast Nevada Wednesday will cause some breezy
conditions across much of the area.

.LONG TERM...Saturday through Tuesday.

The models continue to show differences in the pattern for this time
frame although it does look like by Tuesday we will likely see high
pressure start to park roughly near the Four Corners region. Through
Tuesday it still looks pretty dry over the forecast area with
temperatures still near or only a little above normal. There are
indications from the models perhaps sometime later next week, if the
high stays near the Four Corners area, some moisture may start
getting pushed up into northwest Arizona and southern Nevada.
Confidence in this remains low at this point.


.FIRE WEATHER...Still expecting dry conditions through this coming
weekend with some breezy periods. The strongest winds look to be
over western San Bernardino County this evening but humidity will be
coming up above critical levels some time this evening. For
Wednesday, it looks like Mohave County, away from the Colorado
River, will see the strongest winds with gusts at or greater than 35
mph and a Red Flag Warning has been issued. Somewhat breezy
conditions are expected elsewhere Wednesday but overall it looks
like gusts will remain below 35 mph.


.HYDROLOGY...Observed flows on unregulated creeks, specifically
Independence Creek, Big Pine Creek and Rock Creek indicate flows
continue to slowly decrease from their peak flows which occurred
last week. However, creeks, streams and rivers along the eastern
Sierra slopes of Inyo County as well as the Owens Valley will
continue flowing high and fast into the weekend. Minor flooding
could occur near creeks as well as a few low water crossings on some
roadways. Remember, never drive through flooded roadways or around
barricades. Also, pastureland or farmland adjacent to creeks,
streams or rivers could experience areas of standing water.


.AVIATION...For McCarran...Expecting south/southwest winds 10-15
knots with gusts around 25 knots through this evening then winds
becoming light and variable overnight. Winds will favor a light
easterly direction much of Wednesday until southwest winds kick in
about 22z, sustained around 15 knots with gusts around 25 knots. No
clouds near the terminal through Wednesday.

For the rest of southern Nevada, northwest Arizona and southeast
California...Mainly west to southwest winds 10-15 knots with gusts
20-25 knots through early this evening then variable winds 5-15
knots tonight. Gusts around 30 knots will occur over the western
Mojave Desert near KDAG. Wednesday, west/northwest winds 10-15 knots
will push into Esmeralda, central Nye and Lincoln Counties with
southwest winds 10-20 knots and gusts25-30 knots elsewhere.
Generally clear skies through Wednesday.
