Area Forecast Discussion

230 PM PDT FRI JUL 22 2016

Above average daytime temperatures will continue through this
weekend, with hot conditions likely next week as strong high
pressure builds into the Great Basin. High pressure and a very
dry air mass will prevail for the upcoming week.



Current water vapor satellite imagery shows an impressive dry
slot stretching from 140 West over the east Pacific and then
across northern CA/NV into ID. This is the dry slot which brought
the very dry conditions to the east Sierra and NV. This dry air
will remain in place this weekend as heat builds each day. Highs
in western NV should be in the mid-upper 90s this weekend. Warmer
sites may reach triple digits Sunday. Due to the dry air mass,
lows will still cool off to the 40s and 50s each morning, with
some of the cooler Sierra valleys dipping into the 30s.

For Monday, model simulations have been consistent in showing a
weak trough that could initiate mid-level southerly moisture
transport and possible afternoon cumulus build-ups over the
mountains. JCM

.LONG TERM...Tuesday through Friday...

Next week is going to be HOT. High pressure builds into the Desert
Southwest and becomes entrenched through the workweek. Next week is
climatologically the hottest week of the year and temperatures will
be around 6-8 degrees above average. High temperatures in western
Nevada look to remain in the triple digits for the whole week with
Sierra valleys in upper 80`s to low 90`s.

Thunderstorms would normally be expected to form eventually with
this pattern, either when southerly flow allows moisture into the
area or as the heat creates convection off the Sierra. However, the
most recent EC brings another trough into the Pacific Northwest next
weekend, which has been the pattern so far this summer. That
would keep dry southwest flow over the region and discourage
thunderstorm development. If thunderstorms do develop it would be
late in the week or next weekend. -Zach


Very dry air aloft will result in few...if any...clouds through
early Sunday. Light winds will be common with some Zephyr breezes
each afternoon. Gusts east of the Sierra could reach 20 knots for
KRTS/KRNO/KCXP/KMEV/KMMH with lesser gusts well east of highway
395. 11/20
