Area Forecast Discussion
National Weather Service Las Vegas NV
1255 AM PST Mon Nov 29 2021

.SYNOPSIS...Dry conditions with afternoon temperatures flirting
with record highs will continue through week ahead. A hint at a 
pattern shift is suggested beyond next weekend which may bring a 
return of cooler and breezier weather. 

&&

.DISCUSSION...through Monday.

500mb ridge axis remains overhead today and will move little
through the week, resulting in a continuation of mild and dry
weather through at least Saturday. Given 500mb heights of 580dm+,
temperatures will be quite warm by late november/early december
standards, augmented somewhat by the low sun angle and limited low
level mixing. Nonetheless, afternoon highs will remain 10-15
degrees above normal, and within striking range of daily record
highs. 

By late in the week, heights begin to decline slightly which may
offer a degree or two of cooling by Friday and Saturday, but
overall very mild and dry conditions will continue. 

Beyond Saturday, extended range guidance continues to hint at a
pattern shift towards cooler and more unsettled conditions at 
some point next week. This is in response to the Great Basin ridge
shifting offshore of the West Coast, and allowing an inside 
slider type weather system to drop inland from the Pacific 
Northwest. Too early to be confident on this scenario or it's 
impacts, but a trend towards more seasonable temperatures by early
next week looks fairly likely.

.AVIATION...For McCarran...No operationally significant impacts 
expected. Light winds below 7 knots are expected to remain and may 
be variable at times through the TAF period.

For the rest of southern Nevada, northwest Arizona and southeast 
California...Some breezy north winds will be mostly isolated to KIFP 
this afternoon with gusts around 20 knots. Elsewhere, expect light 
and diurnal winds and mostly clear skies. No operationally 
significant impacts expected. 
&&

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