KEY MESSAGES
* Gusty northeast to east ridge winds return tonight through Saturday night, with chilly breezes for western Nevada valleys. * Saturday will be the coldest day of the upcoming week, with hazardous wind chills near or below zero degrees for Sierra backcountry areas. * A slow warming trend will bring back the valley inversions next week, then a weak weather system may bring chances for light showers, mainly along the Sierra mid-to-late next week.
DISCUSSION
Afternoon highs will drop 5-10 degrees tomorrow, with highs in the low 40s and low 30s across valley locations and the upper elevations, respectively. This is due to a cold front dropping in from OR late tonight through Saturday. Said cold front will also bring increased winds, mainly along ridges, with north/northeasterly gusts up to 50 mph. Wind chill values will drop to near or below zero Saturday morning, aligning with the peak in winds in the late morning/early afternoon timeframe. For backcountry recreators, make sure to bundle up, especially in the morning hours as those cold wind chill values will increase the threat for frostbite and/or hypothermia.
After Saturday, highs rise back to near normal with highs in the upper 40s and low 40s for valleys and high elevations, respectively. Ridging settles back into place Sunday, continuing through the majority of the next week. This will introduce a slight warming trend and bring back valley inversions and light winds. This will renew the chances for hazy skies and freezing fog for fog-prone Sierra valleys.
A low pressure system may bring increased chances for precipitation Wednesday/Thursday, though chances are low for now (15-20%). Snow levels are around 6-6.5 kft for that time frame but there is plenty of time for things to change. Stay tuned for more details as we get closer!

AVIATION
VFR conditions expected for the majority of the weekend, with the exception of the overnight hours through tomorrow afternoon where MVFR conditions are likely due to low cloud cover. This is due to an incoming cold front, which will also increase winds with gusts up to 45 kts along ridgetops. Localized areas of LLWS are likely with these increased winds.
FZFG is also possible (20% chance) at KTRK again tonight. However, if those winds pick up and mix in, it'll be harder for fog to form.
