.DISCUSSION...

One more day of warm, above average temperatures is expected this
afternoon before a series of cold fronts bring gusty northerly
winds and a temperature drop of about 20 degrees by Sunday.

For this afternoon, expect dry and warm conditions, with highs
reaching the lower 80s and the low 70s in Sierra valleys. A very
dry air mass remains in place, with afternoon relative humidity
dropping into the lower teens and even single digits. Another
night of poor overnight RH recovery is expected (below 30%),
mainly along mid-slopes across the western Nevada Basin and Range.

A series of cold fronts is still on track to provide significant
cooling over the weekend along with gusty winds. Highs drop to
near average Saturday (low 70s western Nevada, mid-60s Sierra),
then fall another 10 degrees Sunday (near 60 for western Nevada,
mid-50s Sierra).

Sustained winds strengthen from the northwest at 15-20 mph
Saturday, shifting north to northeast at 15-25 mph Sunday, with a
60-70% chance of gusts up to 40 mph for areas mainly south of
US-50. Areas across S.Lyon and Mineral counties could encounter
stronger sustained northwest-north winds around 25-35 mph on
Sunday. As such, a wind advisory has been issued for these areas
on Sunday.

These winds may generate blowing dust downwind of desert sinks,
which may reduce visibility along parts of US-50 in Churchill
County into Mineral and southern Lyon Counties. Additional impacts
include difficult crosswinds for high-profile vehicles, aviation
turbulence, and hazardous boating conditions. Lake wind advisories
have also been issued for area lakes for both Saturday and Sunday
due to the expected winds.

A band of showers (10-20% chance) may accompany the main cold
front Sunday morning, with light snow showers possible above
5500-6000 ft. Conditions turn drier and warmer early next week as
the trough exits and high pressure builds, with highs returning to
the 70s and 80s by Wednesday. Fuentes

afternoon wind gusts around 20kts this afternoon.
