DISCUSSION
This week looks to be cool, calm, and collected through Thanksgiving. The only exceptions will be in the next 48 hours where freezing fog is likely for fog-prone Sierra valleys, such as the Martis Valley and around Truckee, this morning. Additionally, a brief low pressure system skirts past to the north, bringing light chances for showers along the OR border Monday morning. Ahead of this low, expect slightly increased afternoon breezes today with ridgetop gusts up to 40 mph. Due to those enhanced breezes, the threat for freezing fog to develop is lesser ahead of Monday morning. Though, fog may redevelop in the mornings by mid- week as ridging settles back in place.
Afternoon highs will lean above normal across much of the area this week, with highs in the mid to upper 50s. Overnight lows will hover within a few degrees of normal with lows near freezing. With ridging returning by mid-week over the Great Basin, this will allow for the return of valley inversions, bringing the possibility for isolated air quality concerns.
Beyond Thanksgiving, the models have quickly deteriorated in confidence on the timing and placement of the next storm system. Mountain snow, valley rain, and gusty winds can be expected of some flavor as early as Friday though amounts, magnitude, and timing will have to wait to be resolved until mid-week at the earliest.
