...COOLER WITH PRECIP CHANCES INCREASE NORTH OF I-80 FRI-SUN...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

Weak troffing along the west coast will be reinforced by an area of 
low pressure dropping southeast from the Gulf of Alaska toward the 
region tomorrow and persisting through the upcoming weekend as 
individual disturbances rotate around the cyclonic flow. Chances of 
precip will increase late Thursday or early Friday mainly for areas 
north of I-80 and over the higher terrain. This will continue into 
Saturday and Sunday as the overall flow regime remains 
similar...before finally weakening Monday into Tuesday.

Freezing levels currently from 13000- to 16000-feet will bottom out 
late Saturday into early Sunday from 7000-feet north with a sharp 
gradient over the central portion of the region and 17000-feet far 
south. These will rebound up north by the middle of next week closer 
to 11000-feet.
