.SYNOPSIS...

Temperatures will begin to heat up once again on Tuesday through
Thursday with high temperatures approaching the triple digits
across W.Nevada. Areas along and south of US-50 may also see a
slight chance for isolated showers and thunderstorms through this
evening and again tomorrow. A cooling trend with increased winds
looks likely going into the weekend.

.DISCUSSION...

After a minor dip in temperatures over the past few days, the
heat will be on the increase once again as afternoon highs return
to near record territory on Tuesday and Wednesday. Highs will
return into the upper 90s across western Nevada with hotter
valleys touching the 100 degree mark each afternoon. Overnight
lows will also be near record warm territory as lows are expected
to run 10-15F above average. As such, this will result in
widespread moderate heat risks with isolated major heat risks
across the hottest W.Nevada valleys. However, there are signals
for a cooling pattern over the weekend with temperatures even
cooling down to near average for the second half of next weekend.

Daytime heating may also fire a few showers and isolated
thunderstorms each afternoon with the best chances targeting
around midweek thanks to increasing diffluence aloft associated
with a closed low tracking across the southwestern U.S. Overall
looking at 10-15% chances mainly along Sierra south of US-50 this
afternoon with chances creeping as far north as the Pine Nuts in
Douglas County on Tuesday. Precipitation chances will be more
limited on Wednesday with Thursday`s storm prospects largely
governed by the track of the closed low. These storms will be
capable of small hail, brief heavy rains, and gusty outflow winds.

While typical afternoon westerly zephyr winds are expected each
afternoon, we could see some enhancement to these winds by Friday
afternoon/evening as a dry cold front tracks into the region.
Southwesterly gusts in the 25-35 mph range are possible with up to
40 mph in wind prone areas. Sierra ridgetops could also see gusts
around 50 mph. This could create some choppy conditions across
area lakes along with cross wind issues for high profile vehicles
Friday afternoon. Fuentes
