Synopsis A strong cold front will sweep across nevada this
afternoon bringing windy conditions to much of the area along with
scattered showers and isolated thunderstorms to portions of central
nevada. A dusting of snow will also be possible in the southern
sierra. Much cooler air will filter into the region today through
the weekend making conditions feel much like fall. Dry but cool
conditions will linger into early next week.

Update Overall the forecast is on track. I made a few morning
updates to account for general trends and fine tuning of afternoon
precipitation chances. Winds have picked up already across the
region but for the most part remain below advisory criteria so i
will retain the start time of 11am for the wind advisory. I also
added some mention of blowing dust to the forecast for the western
mojave desert given the expected wind gusts and dry soils.

Short term Through Saturday night.

A strong cold front is forecast to sweep across nevada ushering in
some of the coolest air we have seen in a while. First, gusty winds
will occur across much of the area today with most areas seeing
winds over 30 mph. Ahead of the front, a belt of stronger winds will
occur across lincoln, clark, southern nye, mohave, and portions of
san bernardino counties where winds will gust over 45 mph are
expected this afternoon. The current wind advisories for those
locations look good and no changes necessary. Gusty winds will also
occur this morning for the eastern slopes of the southern sierra
where wind gusts approaching 60 mph will be possible at the higher
slopes. Morning radar imagery showing precipitation falling just
west of mono county this morning and will likely reach the sierra of
inyo county around sunrise. This band of moisture just ahead of the
front will continue to push east during the day affecting mainly
esmeralda, central nye and lincoln counties. Some precipitation may
fall in the spring mountains and northern mohave counties late this
afternoon, but overall amounts will generally remain light. Due to
strong forcing with the front thunderstorms are also possible over
central nye and lincoln counties this afternoon and have added those
to the forecast. It is also possible for a few thunderstorms over
esmeralda county, but conditions look more favorable east.

High temperatures today will be about 10 degrees lower than what was
seen on Wednesday with additional cooling of 5 degrees on Friday
leaving most areas about 10 to 15 degrees below normal for this time
of year. Low temperatures Friday morning will likely be the coldest
since mid may. Some areas of esmeralda county including dyer will
likely see the first freeze of the season. Have gone ahead and
issued a freeze warning for esmeralda and central nye counties for
Friday morning to cover the likelihood of seeing these freezing
temperatures.

Long term Sunday through Thursday.

Dry northerly flow will follow the much anticipated cold front
arriving just in time for the first weekend of fall. The main
impacts will be the potential for some isolated freezes this weekend
during the early morning. Areas of concern include higher elevations
across the southern great basin and inyo county where temperatures
will be below or near freezing. Proper precautions regarding pets
and sensitive vegetation should be considered this weekend in these
areas. As the upper low exits the region, expect dry conditions and
unseasonably cooler temperatures through the weekend. Temperatures
will increase 1-3 degrees each day under continued board troughing
before subsequent ridging midweek. Temperatures will be near normal
by Thursday. Mostly clear skies and breezy north winds (especially
along the colorado river valley) can be expected each afternoon.

Fire weather Windy conditions will develop today with gusts
exceeding 40 mph at times along a belt from the western mojave
desert into southwest utah, and also along the sierra crest. Much
cooler conditions will follow this system with below normal
temperatures expected this afternoon through early next week.

Critical fire weather conditions are not expected due to relatively
high fuel moisture and marginal forecast humidities.

Aviation For mccarran... Gusty southwest winds will occur this
morning with winds between 15 and 25 kts. Winds will then increase
late morning and afternoon with gusts of 30 to 40 knots possible.

Mountain wave activity may produce a few lenticular clouds, but no
operationally significant ceilings anticipated. The primary hazards
will be strong surface winds, turbulence, and mountain wave activity.

For the rest of southern nevada, northwest arizona and southeast
california... Gusty winds will increase this morning with gusts over
30 knots expected across most of the area by this afternoon. Strong
winds over 40 kts are expected across lincoln, mohave, clark and
portions of san bernardino counties.VFR conditions will prevail,
however, expect enhanced winds along with mountain wave and
associated turbulence near mountain ranges through the period,
especially the sierra nevada and spring mountains. Showers and
isolated thunderstorms will occur late this morning and afternoon
across esmeralda, central nye and lincoln counties.

Spotter information statement A more fall-like pattern will bring
cooler temperatures and gusty winds over the next week.

While spotter activation is not anticipated, reports of wind
impacts such as blowing dust or damage are appreciated.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
