Area Forecast Discussion
National Weather Service Reno NV
111 AM PDT Wed Jun 13 2018

.SYNOPSIS...

Temperatures will remain well above average through Thursday with
the hottest temperatures expected this afternoon. Low pressure
moving into the Pacific Northwest will bring breezy conditions
through Thursday with gusty winds possible on Friday. A cooling
trend is expected into the weekend as the upper level low
approaches the region.

&&

.SHORT TERM...

The heat continues today with afternoon high temperatures expected
to reach into the upper 90s across western Nevada valleys with
mid to upper 80s across Sierra and northeast California valleys.
Today will be the peak of our heat for the week as temperatures
will begin to cool into the weekend as an upper trough approaches.

Areas of smoke from the Voltaire wildfire will settle in the
Carson City area as light winds develop through the morning. We
will enter into a period of increased afternoon winds beginning
today and extending into the start of the weekend. Afternoon
westerly wind gusts of 25-35 mph can be expected through Thursday
with gusts up to 40 mph possible by Friday. The combination of dry
conditions and gusty winds may result in periods of critical fire
weather conditions over the next few days along with choppy
waters on area lakes.

Today`s heat will add some instability into the atmosphere which
will produce cumulus cloud build ups and may trigger isolated
showers and even a thunderstorm mainly across Mono and Mineral
counties. Thursday and Friday should remain dry as instability
decreases due to the cooling expected with the approaching upper
low. Fuentes


.LONG TERM...This weekend and next week...

As the upper low drops into the northern Great Basin this weekend
temperatures will cool to near or even below normal with 60s
Sierra and 70s to low 80s for western NV by Sunday. Moisture,
instability and large scale forcing will be best across northeast
CA and northwest NV Saturday and Sunday so expect these areas to
initially have the best chances of seeing showers and a few
thunderstorms. Winds will continue to be gusty for areas along and
south of I-80 on Saturday as the cold front will be slowly
sagging south through the region in advance of the upper low.

Next week, the upper low is not going anywhere fast as it wobbles
around CA-NV at least through Wednesday and possibly longer. The
upper low will gradually fill/weaken allowing temperatures to
slowly warm. However no significant heat is on the horizon for our
area, probably pushing back into the mid-upper 80s midweek across
western NV with low-mid 70s Sierra. The track of these closed
lows are notoriously difficult to predict so confidence in location
and timing of showers and thunderstorms is low. We have spread
some low chances across the entire area early next week to account
for the possibility. Hohmann

.AVIATION...

Winds aloft and surface thermal gradients increase today through
Thursday as low pressure moves into the Pacific Northwest. Expect
increasing winds with gusts 25-30 kts each afternoon and evening
especially along the Highway 395 corridor, with gusts up to 40 kt
over Sierra ridges leading to areas of turbulence. Winds may
increase further on Friday as the low drops farther south into
northern CA/NV. MJD
