...TEMPERATURES INCREASING TO ABOVE NORMAL THROUGH THE PERIOD...
...VERY SCATTERED SHOWERS POSSIBLE FRIDAY INTO THE WEEKEND...

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

Current setup shows several disturbances rotating through general 
troffing across the northern Rockies...while a robust area of high 
pressure continues to strengthen and slowly nudge eastward over the 
eastern Pacific. This places the region under northwesterly flow 
aloft. Through the rest of the week...the area of high pressure will 
make its way closer to the west coast and settle somewhere around 
130W. This will bring a period of above normal temperatures to the 
region with the peak still appearing to occur on Friday with 
anomalies of plus 5- to plus 20-degF over seasonal normals. This 
feature will stick around in one form or another into next week with 
warmer than average temperatures anticipated. Also...models continue 
to hint at the potential for very scattered convective showers to 
develop later this week (Friday) and last through the weekend with 
the best coverage during the afternoon and early evening hours. Look 
for the southern Sierra...far southern CA...and southern NV to be 
the location of best chances of this occurring. 

Freezing levels currently range from 12000-feet northeast to almost 
18000-feet southeast along the southern CA coast. Look for slight 
fluctuations through the period into next week...as the area of high 
pressure remains the dominant feature along the west coast.
