KEY MESSAGES

* Seasonal temperatures and dry conditions prevail across the area for the first day of Astronomical Summer.

* Above average temperatures, and widespread moderate HeatRisk starting Monday through at least Thursday for western NV, with typical afternoon breezes.

* Model ensembles are showing a ridge breakdown the end of the week, with an increase in winds and lower temperatures.

DISCUSSION

* Today we'll have zonal flow over the region. This will translate into a sunny, quiet weather day with seasonal temperatures and typical westerly winds this afternoon. Otherwise, it's a great day to be outdoors enjoying the first day of astronomical summer! * For the upcoming work week, ensembles all show a weak upper level ridge setting up over the western US. As a result, temperatures will once again increase back into the mid to upper 90s for western NV, eastern Lassen, and the lower elevations in Mono County from Monday through at least Thursday. This will result in several days of widespread moderate, to localized Major HeatRisk. Temperatures this week for the eastern Sierra communities will end up mostly in the 80s. * By Friday, ensembles are showing a breakdown of the upper ridge as another trough moves into the western US. While details on the exact path and strength of this trough are still low, it's worth noting that blended guidance is showing increasing winds throughout the region as well as 10-15% chances for showers near the Oregon border. This will result in fire weather concerns, as well as impacts to aviation and outdoor recreation. -McKellar
