...REMNANT SHOWER ACTIVITY TODAY ASSOCIATED WITH DISSIPATING 
ATMOSPHERIC RIVER OVER NORTHERN CALIFORNIA...
...POTENTIAL WEAK SYSTEM OVER THE WEEKEND TO SPREAD MODEST 
PRECIPITATION ACROSS THE NORTH...

.METEOROLOGICAL CONDITIONS (WED PM - TUE AM)...

No change from this morning's forecast to this afternoon with 
dissipating moisture plume currently over northern California and 
potential disturbance over the weekend. Guidance continues to vary 
on timing and magnitude for the weekend system, with the 12Z EC 
placing a 2.25 inch bullseye over Mt. Shasta and the GFS generally 
higher elsewhere. With that being said, precipitation accumulations 
through the weekend are expected to be relatively modest and <1 
inch. Afternoon forecasts continued to mostly follow guidance from 
the NBM. 

Freezing levels will remain relatively high throughout the rest of 
the work week, peaking at 11k to 14.5k feet north to south Friday 
night. Levels are forecast to lower during the weekend disturbance 
to 7k across the north and 13k across the south on Sunday evening.
