.DISCUSSION...



A few lingering showers remain this morning across areas south of

Highway-50 this morning. These showers should end by sunrise as 

the upper level trough leaves the area. In its wake, northerly 

flow brings cool and dry air. However, this afternoon will be 

slightly warmer than yesterday due to mostly clear skies. 



A high amplitude upper level ridge from the Eastern Pacific

extending north towards the Alaska Peninsula takes over through 

Friday morning resulting in a warming trend. Afternoon highs will 

be around 5 to 10 degrees above average for this time of the year.

Also expect typical afternoon westerly winds each day. 



On Friday afternoon, a weak upper level shortwave trough pushes 

through the PacNW. This system will lead to an increase of our 

typical afternoon westerly winds with gusts most likely in the 25 

to 35 mph range with a 10-60% chance of gusts exceeding 40 mph 

over wind prone areas. The main areas of concern will be north of 

I-80, including mountain ridges and eastern slopes of mountains. 

Temps will stop their gradual increase on Friday with this system.



The ridge quickly returns on Friday evening and continues a slow 

eastward trajectory towards the Desert Southwest. This will allow 

for warmer and drier air to move in leading to higher afternoon 

temperatures this weekend and early next week. Western Nevada and

NE California valleys have high (60-90%) chance of reaching their

first 90 degree days of the season (Mon/Tue). The NV Basin and 

Range lowest valleys may reach the mid-90s by Monday. Moderate

HeatRisk is likely over western NV lowest valleys on both days as

temperatures have 50-60% chance of breaking the high temp records.



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 rain chances into the forecast. The 

cloud cover will help drop temperatures back into the 80s, but we 

remain 10-15 degrees above average.
