Area Forecast Discussion

211 AM PDT Fri Oct 30 2020

.SYNOPSIS...Dry weather, light winds, sunny skies and temperatures 
above seasonal normals can be expected through the middle of next 
week.

.DISCUSSION...Today through Thursday.
Quiet weather is in store for the Desert Southwest through at least 
the middle of next week. Due to the light winds, lingering smoke 
from ongoing wildfires may funnel back into the area, particularly 
along the Owens Valley.

A shortwave trough will form over our region over the next 24 hours 
that will reside just off the Baja Coast through the weekend before 
closing off and moving back across our area early next week. Would 
not be surprised if breezy conditions arise as a result, and 
moisture aloft that moves inland with the low will give us a slight 
increase in cloud cover Sunday and Monday. Otherwise, light winds, 
sunny skies, and above-average temperatures expected through the 
forecast period as a ridge of high pressure builds across the region 
midweek.

The extended forecast for the end of next week through next weekend 
indicates moderate certainty of a pattern change in the form of a 
deep trough digging through the Desert Southwest once again. Details 
such as timing and strength are still being resolved. Impacts will 
likely include an increase in wind speeds and a drop in 
temperatures. Will elaborate on to what extent - if at all - we will 
experience these impacts over the next week as our confidence 
increases.

For the rest of southern Nevada, northwest Arizona and southeast

with no weather related operational impacts expected.
