...HIGH PRESSURE TO BRING WIDESPREAD ABOVE NORMAL TEMPERATURES 
THROUGH THE FORECAST PERIOD...
...SLIGHT CHANCE OF SOME SCATTERED SHOWERS OVER PARTS OF THE SIERRA 
TODAY/TOMORROW...

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

A strong area of high pressure remains over the eastern Pacific with 
higher 500 mb heights expanding into the west coast of the US. This 
will continue to raise afternoon high temperatures, particularly 
across CA. Anomalies today are expected at +5 to +15 deg F with 
parts of the Bay Area +20 deg above seasonal normals. Higher 
temperatures will spread across the region the rest of the week and 
into the weekend as 500 mb heights remain high overhead. Models 
continue to suggest the potential for some afternoon/early evening 
convective showers over parts of the Sierra today and tomorrow. 
Otherwise, no widespread precip is expected during the current 
forecast window. Looking into the longer range, some ensembles 
suggest temperatures lowering some late next week but still 
uncertain. Freezing levels generally above 13 kft throughout the 
period staying steadily around 14-16.5 kft starting tonight.
