KEY MESSAGES

* Warmer and drier conditions expected through Thursday with typical afternoon breezes.

* Isolated shower and thunderstorm chances, mainly confined to the Eastern Sierra and Mono County, on Wednesday and Thursday afternoons.

* A significant cooling trend and breezy conditions are forecast for Friday through the upcoming weekend.

DISCUSSION

Much of this week will be marked by warming and typical afternoon breezes. Daytime highs will once again reach into the 90s across western Nevada, with upper 80s back in the Sierra valleys. Overnight lows will generally be in the 60s for western Nevada valleys while the Sierra valleys will trend into the low 60s to even some 50s.

By midweek, a trough digs from the Pacific Northwest, bringing cooler and breezier conditions, as well as some shower chances. First, the shower chances arrive to the Sierra Wednesday, with less than 5% chances along the crest. Thursday, better chances creep into Mono, Mineral and Lyon (15-35%) counties, with some guidance suggesting some showers may sneak as far north as Reno and the Tahoe Basin (10% chance).

Then, winds increase Friday and peak on Saturday, with chilly temperatures settling in for Saturday. Winds will reach 35-40 mph for Friday and 40-45 mph for Saturday. This will bring about elevated to critical fire weather conditions this weekend. The trough will exit for Sunday into Monday, with cool, dry weather ahead. HRICH
