National Weather Service Reno NV

1200 PM PDT Sat Mar 21 2026



.KEY MESSAGES...



* Heatwave continues into next week.



* Breezy winds this afternoon will bring recreation impacts to lakes 

  in northwestern Nevada.



* The forecast remains dry through next week, but there are hints of 

  cooler and wetter weather to kick off April.

.DISCUSSION...



* I'd say rinse and repeat, but we aren't seeing any moisture to 

  speak of. Bottom line: The unusual March heat continues. While 

  it's not as hot as say yesterday when we set a new all-time record 

  high of 88 degrees for the month of March at KRNO, high 

  temperatures continue to be near or above record levels through 

  the middle of next week.



* Our slight "cooldown" this weekend is thanks to an area of low 

  pressure brushing through the northwest CONUS, leading to a 

  flattening of the potent ridge that is entrenched over the west. 

  With this comes an uptick in afternoon westerly breezes today, 

  with the strongest gusts for areas of northwest Nevada north of US-

  50. With wind gusts around 35 mph, Pyramid Lake and Rye 

  Patch/Lahontan Reservoirs will see choppy conditions this 

  afternoon.



* Ensembles and AI deterministic forecast models are hinting at 

  troughing moving into the west to start April. While roughly 80% 

  of meteograms are showing cooler conditions and some rain and even 

  mountain snow, this signal continues to be pushed back. We first 

  saw it showing up around March 25-27, then each day it was later 

  and later, now around April 1-3. Time will tell...

.AVIATION...



* Potential exists for mountain wave turbulence today with the 

  increased FL100 winds around 25-30 kts. Otherwise, anticipate wind 

  gusts of 20-30 kts at terminal sites 19z-03z this afternoon. 



* Ongoing heatwave isn't quite hot enough for major density altitude 

  concerns, but it's still abnormal to even need to consider than 

  one in March! 



* VFR conditions to continue with typical diurnal wind flow.
