.SYNOPSIS...
Gusty north to east winds continue this morning, diminishing this
afternoon. Widespread Valley highs in the 90s Friday into next
week.

&&

.DISCUSSION...
Troughing will remain over the Great Basin Region through Friday,
as high pressure tries to build eastward over California from the
Pacific. Main ridging with this high pressure system will spread
north of California over the Pacific Northwest. Pressure gradient
between these two feature will relax today with diminishing winds.
Winds have already diminished over the Sacramento Valley and have
expired the wind advisory, as speeds are generally below 20 mph.
Will keep the the mountain advisory going where a few gusts from
40-50 mph are still occurring.

A gradual warming trend will occur through the week into the
weekend with temperatures reaching well above normal levels from
10 to 15 degrees from this afternoon into next week, as Valley
highs climb into the upper 80`s and low 90`s. This will represent
and huge change from the previous week where temperatures have
been mainly in the 60`s and 70`s and will bring brief periods of
moderate heat risk during the afternoon hours.

Dry weather is expected for most of the area, though the Great
Basin low will retrograde (move west) through Friday. This will
bring some instability and moisture over the central Sierra. Some
Friday afternoon showers and thunderstorms are possible over the
Sierra Crest south of Highway 50.

&&

.EXTENDED DISCUSSION (Monday THROUGH Thursday)...
Clusters continue to show ridging as the dominant forecast
feature through the extended, continuing our stretch of above
normal temperatures and generally dry weather. Clusters show some
uncertainty regarding the strength of the ridge in the Pacific
creating a larger range of possibilities for afternoon
temperatures next week. The NBM reflects this high temperature
uncertainty, with spread of 8-12 degrees mid to late week across
points of the Valley, making exact forecast details uncertain at
this point. The spread has lowered slightly, increasing confidence
of warm and dr weather continiuing. The current forecast has
afternoon high in the upper 80s to mid 90s in the Valley with
mainly 70s and 80s for the mountains and foothills.

Dry weather continues across the area next week except for a
slight chance of Monday afternoon showers and thunderstorms are
possible over the Sierra Crest south of Highway 50 but forecast
ingrediants don`t look to support development of any impactful
thunderstorm or convective activity.

&&

.AVIATION...
VFR conditions across interior NorCal over the next 24 hours. In
the Valley, northerly surface winds of up to 10-15 kts with local
gusts of 15-25 kts through Thu 21z. In foothills and mountain
areas, north to east surface wind gusts of 30-45 kts through about
18Z Thursday. Afterwards, wind decrease with 20-35 kts gusts over
the mountains and areas of the foothills through 12z Fri and
light winds in the Valley.

&&

.STO WATCHES/WARNINGS/ADVISORIES...

Foothills/Sacramento Valley-West Slope Northern Sierra Nevada-
Western Plumas County/Lassen Park.
