Area Forecast Discussion

.SYNOPSIS...Much drier air has started to sweep into the
area which will limit any thunderstorm potential to far eastern
Mohave County Arizona today. The entire region will be storm free
Wednesday and Thursday while temperatures stay closer to mid-August
normals.

&&

.SHORT TERM...Through Thursday night.

Much drier air has penetrated as far east as southern Nevada this
morning where surface dewpoints are running around 20 degrees lower
then 24 hours ago. That drier air won`t quite get scoured out of
northwest Arizona today so there will be isolated thunderstorm
potential in far northeast Mohave County. Otherwise today, there is
a low probability (10%-30%) of wind gusts greater than 30 mph in
Clark, Mohave and San Bernardino Counties.

On Wednesday and Thursday the entire area will be storm free under
dry/stable conditions. Has not been the case much this Summer, but
temperatures will fall within a few degrees of mid-August normals.

.LONG TERM...Friday through Monday.

High pressure will begin to rebuild over the Four Corners late in
the week and over the weekend. This will allow for the flow aloft to
trend more southerly with time, versus the drier southwesterly flow
earlier in the week. Forecast guidance remains uncertain on how
quickly moisture will return to the region, but increasing storm
coverage is likely over Northwest Arizona through the weekend, and
perhaps expanding west into southeastern Nevada and eastern San
Bernardino County by early next week. Points further west will
likely still be under a rather dry and stable flow.  Otherwise,
temperatures will remain a few degrees above seasonal averages.

.AVIATION...For Harry Reid...Southwest winds will remain in place
through much of today with speeds 7-10 knots with gusts up to 20
knots this morning. Wind speeds are expected to increase later this
morning with speeds 10-15 knots and gusts 20-25 knots. This
southwest flow will bring in drier air which will keep any
thunderstorm activity well east of the airport. Skies will be SKC-
FEW120.

For the rest of southern Nevada, northwest Arizona and southeast
California...South-southwest winds will develop at most TAF sites
through this afternoon with gusts generally 25-30 knots from KDAG to
KLAS. Winds at KBIH will generally remain light through the day with
increasing northwest wind after 00z this evening. Drier air will
push into the region today, but a few storms will be possible from
early this morning through the afternoon over northwest Arizona.

&&

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report
any significant weather or impacts according to standard operating
procedures.
