.Synopsis...
Dry weather. A slight cool down today then a return to well above
normal temperatures next week. 

&&

.Discussion...
Satellite indicates the upper low was located near the Four Corners 
region early this morning with clear skies across northern 
California in its wake. Some stratus has begun to form on the
western side of the Sacramento Valley, with any low cloud cover
expected to dissipate by late morning. Slightly cooler 
temperatures will be seen across the area today behind the 
aforementioned system, with Valley highs in the mid and upper 60s 
and temperatures in the 40s and 50s in the mountains. A trough 
moves across the PacNW today, although it brings little more than 
a few clouds to the northern portion of the CWA with any 
precipitation remaining north of the area. 

Ridging builds back in Monday through mid-week keeping dry weather 
in place. Northerly Valley and easterly Sierra winds will 
be seen Monday and Tuesday, although winds remain not particularly 
strong. Warming temperatures are expected through Wednesday with 
temperatures as much as 10 to 15 degrees above normal by mid-week. 

&&

.EXTENDED DISCUSSION (Thursday THROUGH Sunday)...
A ridge of high pressure will persist along the West Coast later 
next week, resulting in dry and mild conditions. High temps will 
be around 10 to 20 degrees above average for late February. 
Cooling will be possible by next weekend as potential pattern 
change develops. There are signs that the ridge may break down in 
early March, but confidence in any details is low at this time. 

&&

.AVIATION...
VFR conditions the next 24 hours except for local IFR ceilings 
possible in the Sacramento Area thru about 18Z. Local southerly 
surface wind gusts 10-15 kts until 16Z, otherwise surface winds 
less than 10 kts. 

&&

.STO WATCHES/WARNINGS/ADVISORIES...
