KEY MESSAGES

* Lingering showers in southern Mono county will dissipate by this evening.

* Gusty NE-E winds tonight into early Sunday will produce choppy waters on Lake Tahoe and localized turbulence.

* Dry and cool conditions for the weekend with increasing winds Monday.

DISCUSSION

Lingering showers in the far southern portions of Mono county will dissipate as the afternoon progresses and a cold front moves out of the area. This will allow cool and dry conditions to persist for the weekend areawide. Afternoon temperatures will creep up into the 60s for valleys and upper 50s for Sierra communities. Morning lows will continue to hover near freezing for valleys, while Sierra communities will range from the teens to the upper 20s.

That aforementioned cold front is the reason why winds have been mostly northerly this afternoon. These winds will shift northeast/easterly by this evening, and will gust up to 50-60 mph along the ridges. Wind gusts in excess of 35 mph will mix down to lake level, producing waves of 2-4 feet on Lake Tahoe. As such, a Lake Wind Advisory will be in effect from 8pm this evening until 8am Saturday morning. While the winds are expected to die down after daybreak, choppy lake waters will still be prevalent for any early-morning lake recreators.

A brief shortwave to our north Monday will introduce increased winds both for the valleys and ridges, with gusts up to 35 mph and 60 mph, respectively. Additionally, there are light (15-25%) chances for rain showers for NE CA north of Susanville and the Surprise Valley Monday afternoon and evening. Tuesday and beyond, dry and cool conditions prevail. However, long range guidance shows a cold and potentially snowy start to November. Stay tuned for more concrete details as we get closer.

AVIATION

VFR conditions areawide today, with N/NE winds gusting up to 25 kts for Sierra Front terminals. Winds will shift more NE/E after sunset, and will gust up to 55 kts along the ridges, producing LLWS west of the Sierra crest.

The wind will be a limiting factor for FG/FZFG development at KTRK. Lingering moisture from this morning's light rain will promote FG tonight, however, if the winds stay strong overnight, this could limit the development. Additionally, lower cloud decks this evening into early Saturday may produce mountain obscurations.

Dry and calm conditions persist for the remainder of the weekend, with increasing winds Monday due to a shortwave to our north.
