.DISCUSSION...



A high amplitude upper level ridge from the Eastern Pacific

extending north towards the Alaska Peninsula continues through 

Friday morning resulting in a warming trend. Afternoon highs will 

increase to 5-10 degrees above average with typical westerly 

winds the next few days.



On Friday afternoon, a weak upper level shortwave trough pushes 

through the PacNW, increasing our typical afternoon westerly 

winds. Gusts will be in the 20-30 mph range with a 10-50% chance 

of exceeding 40 mph. The main areas of concern will be north of 

I-80, especially mountain ridges and eastern slopes. Temps will 

briefly stop their gradual increase with this system.



The ridge quickly returns on Friday evening and continues a slow 

eastward trajectory towards the Desert Southwest. More warmer and

drier air moves in leading to higher afternoon temperatures

through early next week. W Nevada and NE California valleys have 

a high (60-90%) chance of reaching their first 90 degree days of 

the season on Monday and Tuesday. The NV Basin and Range lowest 

valleys may reach the mid-90s by Monday. Moderate HeatRisk is very

likely over western NV lowest valleys on both days. Temperatures 

have a 50-60% chance of breaking the record highs.



By next Wednesday, the backside of the ridge starts to pull

subtropical moisture from the Gulf of California towards W NV

bringing back clouds and low rain and thunderstorm chances (below

10%) into the forecast. Anyway, the cloud cover will help drop 

temperatures back into the 80s for valley locations, but we remain

10-15 degrees above average.
