.DISCUSSION...

The heat is on for the early part of the week. Plan on triple digit
high temperatures for the lower valley areas with low to mid 90s for
the Sierra locations. Temperatures are running about 5 to 10 degrees
above normal for today and Monday before we start to see some
slight cooling on Tuesday, accompanied by a slight increase from
the typical afternoon breezes. A portion of the concern is the
overnight low temperatures, particularly in the urban areas, where
low temperatures for lower valley areas remained in the mid 60s
to low 70s overnight. We won`t see much true relief from the heat
during the overnight hours until Wednesday or Thursday mornings.
Take precautions with the heat, be sure to limit time outdoors
during peak heating hours (10a-5p), and make sure to stay
hydrated. Maybe today`s the day you binge that show you`ve been
eyeing instead of doing yard work. Also, with the air quality
teetering in the moderate zone, it`s just another reason to be
indoors today. Until fire activity lessens for northern CA fires,
such as the Green Fire, plan on keeping that tab open on your
browser to AirNow.gov.

The thunderstorms were few and far between yesterday, but we had a
handful of lightning strikes as well as some sparse rainfall. Plan
on a similar round of storms today (about 5-15% chance) with the
combination of the hot temperatures and sufficient moisture to
allow a few cells to pop up again between 3p-8p, primarily along
the Sierra and northeast CA. A low pressure system meanders
southward into the region by mid week, bringing increased shower
and storm chances (generally 10-20%) each day this week. This low
will also bring a bit of a cooldown with temperatures falling into
the near-normal category of mid-upper 90s for lower valleys and
lower 80s for the Sierra. Which for July, is still pretty hot!

Next weekend and beyond we`re looking at a hedge toward above normal
temperatures and below normal precipitation, although isolated PM
showers and storms remain possible mainly south of US-50 next
weekend. Time to gear up for much of July to be on the hot side
and mainly dry.

.AVIATION...

* VFR conditions persist with light winds and typical afternoon
  W-SW wind gusts up to 20 kts. Expect a 5-15% chance of isolated
  thunderstorms each day between 21-03Z, primarily for Sierra
  terminals. Primary storm concerns will be brief heavy rain,
  outflow gusts and localized turbulence.

* The hot temperatures may produce density altitude impacts,
  especially for KTRK, KTVL, and KMMH. Slantwise visibility
  reductions remain possible with smoke and haze from wildfires in
  northern California and southern Oregon.
