.DISCUSSION...

...Today...
Temperatures will remain above-normal today as
westerly flow continues aloft and ridging builds over the Eastern
Pacific. A slight "cool down" is expected on Tuesday as ridging
continues to flatten out over Northern California, however
temperatures will still be a few degrees above normal. Winds will
be light, with occasionally breezy onshore flow through the Delta
and southern Sacramento Valley this evening.

...Wednesday-Next Week...
Ridging begins to strengthen and build over Northern California
by mid week, and is on track to dominate the synoptic pattern
into early next week. Temperatures will climb well above-normal,
with Minor HeatRisk returns to the Valley Thursday onward. The NBM
is indicating a 60 to 90% chance of Valley high temperatures
greater than 80 degrees Wednesday through Sunday. Warmer overnight
lows compared to seasonal averages are expected during this time
as well. By late this week, we will see dry conditions intensify
with minimum relative humidity values into the teens over the
high elevation of the Sierra and into the 20s over the upper
foothills.

Temperatures increase into next week with the potential of 90
degrees by midweek across portions of the Central Valley. Be sure
to take extra precautions against heat related illnesses when
spending time outside, especially this coming weekend.

Additionally, locally water ways are still running cold so be sure
to practice cold water safety if spending time on the water this
week.
