Area Forecast Discussion
National Weather Service Las Vegas NV
130 PM PDT Sat Jul 4 2020

.SYNOPSIS...Temperatures will hover around seasonal averages
through the upcoming week with continued dry conditions and
afternoon breezes creating periods of high fire danger.
&&

.DISCUSSION...through next Friday.

The pattern remains much the same through the upcoming week with
the region in the big squeeze - stuck between high pressure to the
southeast and low pressure to the northwest, resulting in dry
southwest flow for the area. As shortwaves move through the
attendant long wave trough in the northwest US, breezy afternoons
will become at least locally windy - with Tuesday looking like the
windiest afternoon in the forecast.

Towards the end of next week, still a lot of model spread as to
where the rebounding high ends up, whether that is somewhere in
the Desert Southwest or in the Southern Plains, which would result
in either continued dry west to southwest flow, or a more
southerly flow.
&&

.FIRE WEATHER...Continued dry conditions and breezy afternoons
will maintain elevated fire weather conditions over much of the
upcoming week. Tuesday looks like the windiest day with critical
conditions across southern Nevada and northwest Arizona where a
Fire Weather Watch as been issued, bookended by poor recovery
both Monday night and Tuesday night.
