Synopsis Strong low pressure will remain in play through
Thursday once again providing scattered showers and thunderstorms to
much of the region. The low will begin to lift northeast Friday with
just a few showers remaining over the eastern portions of nevada.

Expect cool conditions again Thursday with high temperatures around
25 degrees below normal. A warming trend follows heading into the
weekend as temperatures on Saturday will be around 20 degrees warmer
than today. The next upstream system is expected to bring more cool
and unsettled weather to the area late in the weekend into early
next week.

Evening update
Over the past few hours, precipitation coverage has declined due to
waning instability across the region. Only a few light showers
remain, mostly across central mohave county. The 00z klas sounding
should a very low tropopause (~24000ft) which kept afternoon and
evening storms from growing much and becoming very strong. As we
continue to lose heating (already in the mid 50s) and thus
instability, we will lose coverage. Hrrr and href trends indicate
this trend overnight but picking pop chances up towards the mid to
late morning time frame. Some increase pops by 12z but feel this
will be hard to achieve without temperatures rising at least into
the 60s. Thus, made some significant changes to the overnight pop
grids, lowering mostly.

Also lowered min t and wind grids based heavily off the latest
bcconsshort and nbm trends.

A rather un-may weather pattern has set up across the region today
as a cold upper low sits over the desert southwest. Scattered
showers and thunderstorms have developed and are occurring generally
south of a line that stretches from olancha, ca to pioche, nv.

Overall these showers and storms have been rather tame, but a few
cells have produced brief heavy rain with totals between a quarter
and half an inch in less than an hour. With the very cold
temperatures aloft, small hail is also likely with some of these
cells. Snow levels have been around 7000 feet and the lee canyon ski
webcam (8500 ft) showing a light dusting with snow currently
falling. This trend will continue through the afternoon and into the
evening, but overall coverage is expected to decrease. However, with
enough dynamics still in place from the low some showers will likely
continue overnight.

The low is forecast to slowly move northeast Thursday, but there
should still be enough upper dynamics to keep showers and isolated
thunderstorms going once again. It looks like the greatest chance
will remain generally north of i-15. Like today, these should
generally produce small hail, brief heavy rain, and gusty winds.

Temperatures are also expected to change little from today with
highs remaining 20-25 degrees below normal.

By Friday, the low is forecast to move far enough northeast that
most of the area will be dry. The exception will be northern and
eastern lincoln county where a few showers will remain. With the
drier conditions look for temperatures to rise about 10 degrees, but
will still remain several degrees below normal.

The next upstream system is forecast to drop out of the pacific nw
this weekend and move south along the coast into early next week.

Expect a drop off in temperatures and the possibility of more
showers as this system draws near.

Aviation For mccarran... Very light precip continues in the
vicinity of klas but this should continue to lessen through the
overnight hours and precip should be very light anyway. Winds have
calmed considerably this evening and are currently light and
variable across the valley. Expect this to continue through the mid
morning hours before a shift to southeast and eventually southwest
takes place for the late morning and afternoon hours. More precip is
expected in the vicinity beginning shortly after 18z tomorrow
afternoon. This could again result in tricky winds if any outflows
develop near the terminal.

For the rest of southern nevada, northwest arizona and southeast
california... Precip has waned considerably over the last few hours
and expecting precip chances overnight to be very isolated. Winds
across southern nevada have calmed as well. Expecting more showers
and isolated storms to develop tomorrow afternoon shortly after 18z
for the valley, and a bit earlier for kbih. Confidence in any direct
impact to a terminal is low but included vcsh at all terminals
during the afternoon hours as coverage should be similar to today.

any significant weather or impacts according to standard operating

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
