...LINGERING SHOWERS THIS MORNING AS A LOW PASSES TO THE NORTH...
...RETURN OF DRY CONDITIONS AND ABOVE NORMAL TEMPS FRIDAY THROUGH 
EARLY NEXT WEEK...

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

Precip continued across much of nrn and central CA overnight, mainly 
along the coast and over the mountains. Observations report 0.50-
1.50" across the northern/central Sierra and 0.25" to just under an 
inch along the coast from Monterey northward. Lingering showers this 
morning as a low continues to traverse the PacNW with the southern 
edge scraping the northern regional border as it passes. Amounts 
look relatively light at 0.10" or less for most areas, though up to 
0.40" for the srn OR Cascades and over 0.50" for the Ruby mountains 
in ne NV. Precip will diminish this afternoon with showers shifting 
to ne NV as the low moves through ID and into WY by the evening. 
Behind the low, ridging will re-build over the eastern Pacific 
returning dry conditions for the rest of the week and through the 
weekend. This will also return above normal afternoon high 
temperatures with anomalies around +5 to +15 or so deg F through at 
least Monday.

Models then show another low approaching the west coast 
Tuesday/Wednesday. There is some uncertainty as models disagree on 
the path and timing of this next system. There is at least some 
chance of showers along the nrn CA coast into Wednesday morning. The 
official forecast keeps this at less than 0.10" for most areas, but 
ensemble spread at Arcata is anywhere from 0" to 1.25".

Freezing levels today 4-8 kft north of I-80 rising tonight back up 
to 8-11.5 kft for most of the Sierra. Higher freezing levels (10.5+ 
kft) the rest of the week as high pressure returns. This may lower 
some into Wednesday, but uncertainty as it depends on how close the 
low is to the coast at that time. For now expect generally 10-12.5 
kft across the region once the current system passes.
