.KEY MESSAGES...

 - Well-above normal temperatures expected through next week, with
   Minor HeatRisk in the Valley.

.DISCUSSION...

...Today-Friday...

Temperatures will continue to be above-normal today through
Friday as a ridge continues to amplify across western CONUS.
Temperatures will continue to rise, with winds remaining light and
occasionally a breezy onshore flow near the Delta later this
evening. Conditions will be dry, with no precipitation expected.
RH values drop down into the upper single digits to teens for
areas in the higher elevations through Friday during the
afternoon. Clouds will start to increase on Friday evening and
overnight as the ridge flattens slightly and a system moves into
the Pacific NW. Minor HeatRisk within the Valley Thursday and
Friday.

...Saturday-Midweek...

The ridge flattens slightly, with minor chances (less than 15
percent chance) for isolated showers around Shasta County
Saturday. Otherwise, the vast majority of the region will be dry
with continued warming temperatures. Record high temperatures are
possible for some areas this weekend and into next week. Minor
HeatRisk is expected over the weekend for the Valley and spreads
into the Foothills and mountains early next week. Areas within the
Delta and Valley see the potential for Moderate HeatRisk Tuesday
and Wednesday as high temperatures reach the upper 80s to lower
90s. The chance for Moderate HeatRisk sits at 50-60 percent for
areas in the southern Sacramento Valley, the Delta, and northern
San Joaquin Valley Tuesday and Wednesday. Looking out past mid
next week, there is little indication that the ridge will break
down and cool temperatures. Well above-normal temperatures are
expected to continue throughout next week and potentially into the
following weekend.

Be sure to take extra precautions against heat related illnesses
when spending time outside, especially this coming weekend. Additionally,
local water ways are still running cold so be sure to practice
cold water safety if spending time on the water this week.

coverage around RDD through the afternoon and evening. Winds
around 5-10kts going light and variable this evening and
overnight.
