Area Forecast Discussion
National Weather Service Flagstaff AZ
1037 AM MST Fri Jun 7 2024

.SYNOPSIS...Above normal temperatures will continue, although they
will peak today, with some cooling over the weekend. Any isolated
showers and thunderstorms will primarily impact portions of eastern
Arizona through Sunday. Another warming trend returns for the middle
of next week.

&&

.UPDATE...
-- Changed Discussion --
Weak wave moving around the ridge is moving east this
morning, having brought some light showers for parts of the
Mogollon Rim. That shower activity has diminished this morning,
but will potentially reignite with daytime heating upping
instability closer to the Four Corners. Meanwhile, better lift and
instability already has convection ongoing over the White
Mountains. Activity there will be on and off throughout the day.
Hot weather still the main story and impact for the day with more
near record to record highs possible.

.PREV DISCUSSION /419 AM MST/...The ridge across Arizona slowly
deamplifies heading into the weekend, but not before delivering
another hot/potentially record-setting day today. A weak trough
setting up along the West Coast will increase southwesterly flow,
especially today and will push our limited moisture sources
eastward. Chances for high-based convection continue for several
days, but really only affect the eastern zones of our CWA from
here on out.

Continued troughing into next week will eventually dry us out
completely, not that this is a "wet" pattern by any means, with
above normal temperatures persisting.

One more day of our EHW looks reasonable, but fire danger is also
something to think about as southwest winds increase for today. All
in all, much of the state will just see the next seven days as more
of the same.
