Hydrometeorological Discussion

...SYSTEM EXITS FROM NORTH TO SOUTH TODAY...

...DRYING MON-TUE WITH A RETURN TO MORE PRECIP ENDING THE WEEK...



.METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)...



With one disturbance moving through the base of the overall upr trof 

along the CA/MX border...and the primary circulation along the 

southern OR coast beginning to drop southward...the flow aloft has 

turned more northerly with precip becoming a bit more scattered and 

focused along coastal areas and the Sierra. Through Sunday...look 

for the disturbance to parallel the coast before reaching northern 

Baja and shifting off toward the east. As this feature tracks near 

central CA...and eventually southern CA this afternoon and 

evening...look for the best precip to affect these areas before 

tapering off overnight. Freezing levels have bottomed out this 

morning...ranging anywhere from 3500-feet northwest to 6000-feet 

southeast...and between 4000- and 4500-feet along I-80.



As the broad upr trof shifts farther inland...an upr ridge will 

build over the eastern Pacific primarily along 145W before moving 

eastward across the west coast on Tuesday. There may be a few 

showers in the initial northwest flow aloft across far northern 

areas...but coverage and amounts will be limited. Freezing levels 

will rebound with the height rises across the area...peaking either 

late Tuesday or early Wednesday ahead of the next system...from 

about 6000- to 7000-feet north...and 11500-feet for coastal southern 

CA.



The next series of systems expected to impact the region are on tap 

for Wednesday and lasting through the remainder of the week. The 

initial wave of precip will move in through Wednesday as the s/wv 

trof makes its way primarily across the Pacific Northwest and 

northern CA...while a secondary system will dive southeast along the 

CA coast for the end of the week. There are model discrepancies on 

the trajectory of this second s/wv trof...leading to lowered 

confidence for the end of the week.
