...SCATTERED SHOWERS MAINLY SOUTHEAST WITH UPPER LOW...



.METEOROLOGICAL CONDITIONS (SHORT TERM: THU AM - SUN AM)...



The area of low pressure dropping south across the interior of the 

western US has now made its way to the lower Colorado River basin 

near the CA/NV/AZ triple point. Slightly upstream of the area across 

the eastern Pacific an upr ridge has amplified and extends toward 

western Canada. Through the upcoming weekend...look for the upr low 

to meander over the lower Colorado River basin while the upr ridge 

will build across the Pacific Northwest. This will keep the dry 

north to northeast flow across much of the area. Much of the precip 

with the low will be downstream over the Four Corners states with 

only some scattered showers over southern NV...portions of southeast 

CA...and potentially upslope areas near Death Valley NP and the 

adjacent southern Sierra as at least some moisture wraps around the 

primary circulation. Freezing levels in general will range from 

about 10000- to 11000-feet northwest to 5000- to 6000-feet 

southeast. 





.METEOROLOGICAL CONDITIONS (LONG TERM: SUN AM - WED AM)...



The weakening upper level low pressure system will continue to 

linger in the vicinity of the CA, NV, and AZ borders of the Desert 

Southwest. Chances for isolated shower activity should remain over 

the southern portions of the forecast region until a building ridge 

pushes the low eastward by mid-week. Precipitation will generally be 

light (<0.10 inches) and anchored to the higher terrain. High 

temperatures across the north could reach up to 15 degrees above 

normal while the deserts are forecast to remain near to 5 degrees 

below normal on Monday.
