KEY MESSAGES

* Cold tonight, with lows in the teens and 20s for W.NV valleys and teens and single digits for Sierra valleys.

* Warming trend through the weekend with periods of gusty ridgetop winds and light showers near the S.Oregon border.

* Mild and dry into next week with signals for precipitation by next weekend.

DISCUSSION

Brisk east winds will continue to weaken across mountain ridgetops through this evening in the wake of our recent frontal passage. As winds decrease and sky clear tonight, expect frigid lows dipping into the teens and 20s across western Nevada with teens and single digits for Sierra valleys.

Temperatures will quickly rebound through the weekend with near average temperatures by Thursday, followed by highs 5-10 above season averages over the weekend. This will allow both Sierra and W.Nevada valleys to reach the mid to upper 50s with warmer urban valleys nearing 60 degrees.

The overall pattern looks to remain rather benign for the next week with only periodic weak brush by troughs dropping in from the PacNW Thursday and Friday night. These could yield 15-30% chances of light showers roughly northward of Susanville-Gelarch with only a few hundredths of inch of moisture within any showers. Ridgetops gusts of around 50 mph will be possible with passing shortwave trough through the weekend.

A dry and seasonably mild pattern continues into next week with ensemble cluster guidance depicting at least a 40% chance of developing a broad troughing pattern off the west coast. While confidence is still low, this would favor a better trajectory for wetter storm systems to make their way inland. Fuentes

AVIATION

East winds and areas of localized mountain wave turbulence will continue to weaken through the evening. Otherwise expect VFR conditions to prevail through Thursday. Fuentes
