.DISCUSSION...

Warmer temperatures are here to stay for at least the next 10 days.
Record high temperatures (at KRNO) will be the biggest aspect of the
weather as a strong upper level ridge moves over the southwest US on
Sunday. The ridge will remain in place through pretty much all of
next week. Given the strength and duration of this ridge, expect
persistent large-scale subsidence leading to compressed and warming
air, which will give us our record high temperatures.

So, about those records...let`s dive into it. To sum it up first,
Monday through Friday of next week will be the most likely timeframe
to break previous records at the Reno Airport. I won`t get into the
percentages and details of each daily record, but average record
highs next week are in the upper 70`s and our forecast is calling
for highs from 80-85 here in Reno. We have lesser chances to break
records tomorrow and Sunday (about 60-70%), while Saturday will be a
touch cooler, lowering our chances of breaking that record.

But records aside, high and low temperatures will feel remarkably
warmer over the next 7-10 days. Morning low temperatures will get
into the mid-upper 40`s for lower valleys and get up to upper 30`s
in the Sierra. it`ll definitely feel like early-mid June with the
temperatures that we`re able to have. Make sure to stay hydrated,
protect yourself from the sun of you`re outside for a long time, and
be cautious around rivers as they`ll be flowing fast and cold next
week.

.AVIATION...

VFR conditions prevail through the upcoming week. Winds will be
light today, then afternoon west breezes with gusts 15-20 kt return
Thurs-Fri. Winds may then edge upward a bit for Saturday with W-NW
gusts around 20 kt.

For next week, prepare for rising density altitudes as afternoon
highs exceed 80 degrees at western NV terminals starting Monday.

.HYDROLOGY...

An early snowmelt triggered by a major warm up will increase
streamflows across the region. Melting will accelerate next week
as temperatures reach record highs. While rivers will run fast and
cold, they are expected to remain well below flood levels.
However, this premature runoff will greatly reduce late-spring to
early-summer water supply conditions.
