Synopsis
Dry weather will be accompanied with increasing temperatures this
week. Most of northern california will experience above normal
high temperatures.

Discussion
An upper level trough continues to push into the pacnw this
afternoon which will keep our afternoon temperatures slightly
below average. Current readings across the region appear to be
quite pleasant if you like summer weather with the valley ranging
from the mid 70s to the mid 80s while the mountains span the upper
60s to the low 80s. Temperatures will likely climb a few more
degrees before onshore flow returns and brings some relief to the
region tonight.

Come Wednesday, temperatures will begin to warm mid- week as the
trough shifts east and high pressure strengthens. High
temperatures will be above normal across much of the valley
starting Thursday and then continuing into the weekend, with the
hottest conditions, being found north of hwy 20.

Extended discussion (Saturday through Tuesday)
The upcoming weekend will feature a building upper ridge
extending from the eastern pacific into the southwestern u.S.

Recent guidance has continued to waffle about the strength and
duration of the mentioned ridge which suggests some uncertainty in
the temperature forecast. Fairly confident in above average
temperatures for the weekend with valley highs ranging from the
upper 90s to around 105 degrees. By the start of next week, there
has been a trend in the ensemble guidance to bring an upper trough
across the pacific northwest into the north-central states. This
would lower heights a bit which ultimately keeps temperatures down
a bit, although likely still near to above average. One interesting
wrinkle in the forecast is the path of the mid upper reflection of
a tropical invest over the tropical eastern pacific. Some semblance
of an upper low is seen in the 12z gfs ECMWF lifting this feature
across 30n latitude early mid next week. Difficult to say if
anything materializes from this system across northern california.

Overall, expect temperatures around 5 to 10 degrees above
climatology during the period. ~bro

Aviation
Overall,VFR conditions are expected the next 24 hours; however,
there is some question about whether or not some stratus will form
over the sacramento and travis areas. Guidance depicts a small
chance of it again tomorrow morning, but confidence is low in it
actually forming. Wind wise, southwest wind gusts up to 15-20
knots possible across the delta and its vicinity. Otherwise, taf
sites will see wind speeds 12 knots or less.

Sto watches warnings advisories
None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
