.DISCUSSION...Today through Early Next Week.

Satellite through the morning showed an upper level trough lifting
into central Nevada. All overnight precipitation has diminished and
it was dry across the region. Other than some very isolated, low
impact showers on the Sierra crest this afternoon, dry conditions
will prevail the rest of the week as the trough continues to lift
out and ridging builds back in to replace it. Long range ensembles
are in decent agreement that high pressure will build northwest and
set up over the Four Corners region by Sunday. As this is happening,
the next upper level system will shift into the West Coast. Numerous
Ensemble meteograms members show increasing PWATs and there is a low
probability (10%-30%) for over 1.00 inch PWAT in areas south of the
I-15 Sunday or early next week. How this moisture interacts with the
trough sitting somewhere along the West Coast could result in
showers and thunderstorms early next week, however it`s too early to
determine precipitation chances (if at all) or impacts.

Smoke from fires in the Baja Peninsula will be pushed north on south
winds today and Wednesday. The HRRR shows areas of smoke advecting
into the Colorado River Valley, southern Nevada, and Mohave County
at times, however suggests it will mostly be elevated as near
surface smoke (versus vertically integrated smoke) is very low. HREF
shows a no probabilities for reduced visibilities, so most likely
will periods of haze at times today and Tuesday and not significant
surface smoke or impacts.

As ridging builds into the region this week, temperatures will warm.
Temperatures will warm to near normal on Thursday, then above normal
Friday through the weekend. After Minor Hear Risk much of the week,
widespread Moderate Heat Risk and isolated Major Heat Risk returns
for Saturday through Monday. Anyone with outdoor plans this weekend
should be prepared for much warmer temperatures than current levels
and take heat precautions such as drinking extra water and adjusting
plan to cooler parts of the day. As moisture is potentially
introduced early next week, a large spread in temperatures is noted
on ensembles Monday onward.
