Carson City area weather: Heat Advisory through Saturday, temperatures could surpass 100
A Heat Advisory for western Nevada, the Carson City region and northeast California is in effect Thursday through Saturday due to temperatures expected to be near or exceed 100, according to the National Weather Service.
The advisory is from 11 a.m., Thursday through 10 p.m. Saturday and includes the following areas: Reno and Sparks, Carson City, Dayton, Silver Springs, Minden, Yerington, Fallon, Fernley, Lovelock, Hawthorne, Gerlach as well as Susanville, and Cedarville in northeast California.
Near record daytime high temperatures of 99 to 104 forecast Thursday through Saturday, with well above normal overnight low temperatures of 65 to 75, according to the weather service.
High risk of heath health impacts for much of the population, especially those without sufficient cooling or hydration resources, and those outdoors for extended periods of time, the weather service states. While daytime high temperatures will be near or above records, limited overnight cooling will exacerbate heat health impacts especially for those without air conditioning.
Forecasters advise people to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Below is the latest forecast discussion from the National Weather Service in Reno. The discussion changes twice daily and can be found by going here.
With high pressure firmly fixed over northeast California and Northwest Nevada, widespread subsidence over the region will add to already dry conditions and further boost temperatures over the Sierra and western Nevada. Most lower valleys across western NV will see daytime highs topping in the lower to mid triple-digits with some Sierra locations edging into the low 90s both today and Friday.
Reno's projected high today and Friday of 103F will either equal or close in on records set respectively in 2016 (103F) and 2003 (104F). But daytime highs may not be the only record temperatures. Some unusually higher overnight lows across the region could set records as well. Reno's overnight low Friday morning is forecast to only drop to 69F which would equal the highest low temp set only just last year. Overall, the heat health impacts even among the general population and especially those vulnerable populations with no access to air conditioning will be quite high the next few days.
The increased stability, lack of sufficient moisture, and widespread area of descending air over the region will cap any significant convection over the Sierra north of Lake Tahoe and much of the rest of western Nevada. There remains the very slight chance (10%) of an errant storm popping over the higher elevation areas of southern Mono County today with an even better chance (10-15%) of isolated thunder or two over the same location Friday afternoon where daytime heating will be more than sufficient to overpower the lesser subsidence over that more southern region of the eastern Sierra.
Although haze at times could remain widespread across western NV the next couple days, little in the way of any smoke will be a concern across. With low level winds projected by the HRRR mostly from the north and east the next few days, much of the denser smoke and air quality concerns will hover in the vicinity of or west of the more active Oak fire in Mariposa County, Calif.
Long Term
Heat health concerns will still be high to moderate for many areas headed into the weekend. Near record high temperatures as well as warmer than typical overnight low temperatures will continue this heat event for the Sierra and western Nevada. But thankfully, there is light at the end of the tunnel folks.
The pattern is showing signs of changing it up by early next week per ensemble cluster analysis. Many ensemble members are showing an incoming trough pushing into the Pac NW early next week. The incoming trough is projected to disrupt and breakdown high pressure across the West and bring a relief from the hot temperatures.
