Southern san joaquin valley again tuesday. The fog will begin to
Develop around midnight and will become more widespread toward
Daybreak. The fog will begin to lift by mid morning and dissipate
Around noon.

Be reduced to below a quarter mile. If it is absolutely necessary
To drive in foggy conditions...Slow down...Turn your headlights on
In low beam mode and leave extra stopping distance between you and the
Vehicle in front of you. Drive defensively!
The high pressure will give way mid-day tuesday to an approaching
Low pressure system. This storm will affect mainly the northern
Half of the district...With the best chance for rain and mountain
Snow from fresno county northward. Snow levels will start out
Around 7000 feet near yosemite...Rising to around 8000 feet in the
Tehachapi mountains. Snow levels will fall by about 500 feet by
The time the storm moves east of the region wednesday night.
A second storm is expected to reach california beginning thursday
Night. This storm is forecast to linger over the state through the
Weekend...Bringing periods of rain and mountain snow to the central
California interior. Snow levels will start out around 7000 feet
Near yosemite...But fall to around 6000 feet by sunday evening.
Further south...Snow levels will be around 7000 to 7500 feet in

...Patchy san joaquin valley fog will burn off by late morning...
...Storm to reach central california wednesday followed by
Another storm friday into the weekend...
Last day for patchy dense fog in the san joaquin vally as the
Upper ridge of high pressure over california breaks down and
Clouds will increase later today into tonight. The fog will begin
To lift by mid morning and dissipate around noon.
The high pressure system that has brought us above normal
Temperatures over parts of the san joaquin valley will give way
Later today to an approaching low pressure system by wednesday.
The first storm will produce around three quarters to one inch of
Rain from fresno county northward into merced county and one half
To three quarters of an inch of rain from north of kern county to
Fresno county and less than one quarter of an inch in kern county.
Snow levels will be around 7500 feet near yosemite...Rising to
Around 8000 feet in the tulare county mountains south to the
Tehachapi mountains. Snow accumulations above 8000 feet with this
First storm will range from 6 inches in sequoia national forest to
Around a foot at yosemite national park.
Winds will also be a concern with this system. Strong southerly
Flow ahead of the cold front early wednesday will produce south
Winds 25 mph with gusts to 35 mph near merced and sw winds 30 mph
With gusts to 45 mph along the west side of the san joaquin valley
Below the cottonwood and pacheco passes. Winds may also be strong
In the south valley near the base of the grapevine.
A second storm is expected to reach the northern part of the
Region beginning thursday night. This storm is forecast to linger
Mainly north of fresno county through the weekend...Bringing
Periods of rain and mountain snow. Rainfall with this system will
Be around one quarter to three quarters of an inch north of fresno
County with the higher amounts near merced. Rainfall amounts will
Be less than one tenth of an inch north of kern county to fresno
County and little or no precip is expected in kern county. Snow
Levels will range from around 7500 feet near yosemite...To around
8000 feet in sequoia national park...And around 8500 feet in the

Three things to know upfront...
* forecast confidence in the overall pattern is high.
* threat of strong winds for reno/tahoe increasing thurs night
And friday.
* high snow level storms friday through sunday should minimize
Travel impacts over sierra but heavy rain could create rises in
Lower elevation streams.
.Short term...
No major changes to the forecast today, though confidence is
Increasing in periods of heavy precip for the sierra and high
Winds in the lee wednesday-friday. We`ll be issuing a high wind
Watch for tahoe, reno, mono zones thurs night and friday, but no
Snow advisories/watches for the sierra since snow levels are
Likely to be too high for major impacts.
First storm is on track to swing through tomorrow with a period
Of hvy precip in the sierra. Negative tilt trof and thin moisture
Ribbon suggest a quick hit with only a few inches of wet snow
Above 6500 ft. Mslp gradient and increasing flow aloft will result
In gusty winds area wide as well. Lake wind advisories will be
Posted.
Brief lull in systems thursday but it won`t be much of a break wx
Wise with winds increasing during the day. More substantial wind
Threat for tahoe and lee side looks to be thurs night and friday,
With 700mb flow near 60 kts, precip banking up west side of plumas
County, and decent mtn wave/downslope signatures showing up even
In gfs. Sref plume diagrams also indicate period of high winds in
Lee, so we`ve gone ahead with a watch. This has the potential of
Being a rather strong wind event late thurs night into
Friday...Definitely worth keeping an eye on.
Good atmospheric river setup with this second storm friday into
Early saturday will raise snow levels resulting in mainly rain for
Areas below 7500 ft. Potentially 2-4" liquid for crest areas north
Of tahoe; amounts dropping off rapidly to the south. We`ve issued
A hydro outlook to address potential rises in streams and rivers
Due to this heavy rain. Spillover chances into western nv are only
Modest with shadowing signals showing up in gfs/ec data but we`ve
Kept high chance pops for reno/carson area due to uncertainty.
Snow amounts in sierra could be up to a foot, but it would be
Above 8000-8500 ft for the most part, with only localized impacts
To travel.
Cs
.Long term...Saturday through monday...
Potential continues to increase for a significant rainfall event
In the sierra...Northeast california and far western nevada with
Snow levels rising above 8000 feet saturday afternoon through
Sunday morning. The large scale pattern remains unchanged, with a
Deep and warm subtropical plume (atmospheric river) pushing into
Northern california saturday night, with a front passing through
The sierra and western nevada sunday.
The main forecast issues are snow levels and rainfall amounts,
Which will dictate runoff at high elevations, and factor into the
Urban and small stream flood potential. Latest models runs are in
Good agreement in snow levels rising well above 8000 feet. A few
Model runs have shown snow levels for the tahoe basin and mono
County, may rise to 11,000 feet prior to the frontal passage and
During the period of heaviest precipitation saturday night and
Early sunday.
We do want to emphasize main-stem river flooding (truckee,
Walker, carson and susan rivers) is unlikely at this time due to
Ample reservoir storage relatively dry soil conditions. However
Those living near rivers, creeks and streams will want to remain
Aware of the forecasts through the weekend as river levels will be
On the rise.
Rain will intensify the northern sierra saturday, with light rain
Pushing across into western nevada. The period of highest snow
Levels and heaviest rain is focused from saturday night into
Sunday afternoon as the front moves through the sierra and western
Nevada. Potential is there for 6 or more inches of rain from
Western lassen county southward to along the sierra crest from the
Tahoe basin to mono county. Farther east, 2-4 inches are possible
In the tahoe basin to the foothills just west of highway 395, with
Up to an inch on the western nevada valley floors. There are a few
Factors which could produce more rainfall, especially if the front
Moves through the region slowly and warm rain processes increase
Precipitation efficiency as the front interacts with atmospheric
River.
Once the front passes snow levels should drop to near 5000 feet
Well north of i-80, near 6000 feet for reno-tahoe and near 7000
Feet south of highway 50. However the event will be ending as the
Snow levels drops, so significant snow accumulations may not occur
With this event.
High pressure is forecast to build over the sierra and western
Nevada monday and tuesday, with warm and dry conditions. Models do
Hint at a second warm moisture plume reaching the west coast for
The middle of next week. Brong
&&
.Aviation...
High pressure will bring vfr conditions, light winds and a high
Clouds through tonight. A fast moving system will bring period of
(roughly 6 hours) moderate to heavy rain/snow in the tahoe basin
And northeast california after 18z wednesday. Across western
Nevada rain and gusty winds are possible wednesday afternoon.
Conditions should fall to mvfr in rain for the tahoe basin and
Northern sierra terminals. Snow is unlikely to accumulate on
Runways below 6500 feet.
Much stronger winds will reach areas south of portola to lovelock
Thursday night and friday. Surface gusts may exceed 50 kts,
Especially at mammoth and perhaps reno-carson-minden. Certainly a
High potential for mountain waves, turbulent approaches and low
Level wind shear at all terminals.
A period of heavy rain is likely in the sierra and far western
Nevada, with high freezing levels, saturday night into sunday. Brong

Areas below 7500 ft. Potentially 2-4" liquid for crest areas north
Of tahoe; amounts dropping off rapidly to the south. We`ve issued
A hydro outlook to address potential rises in streams and rivers
Due to this heavy rain. Spillover chances into western nv are only
Modest with shadowing signals showing up in gfs/ec data but we`ve
Kept high chance pops for reno/carson area due to uncertainty.
Snow amounts in sierra could be up to a foot, but it would be
Above 8000-8500 ft for the most part, with only localized impacts
To travel.
Cs
.Long term...Saturday through monday...
Potential continues to increase for a significant rainfall event
In the sierra...Northeast california and far western nevada with
Snow levels rising above 8000 feet saturday afternoon through
Sunday morning. The large scale pattern remains unchanged, with a
Deep and warm subtropical plume (atmospheric river) pushing into
Northern california saturday night, with a front passing through
The sierra and western nevada sunday.
The main forecast issues are snow levels and rainfall amounts,
Which will dictate runoff at high elevations, and factor into the
Urban and small stream flood potential. Latest models runs are in
Good agreement in snow levels rising well above 8000 feet. A few
Model runs have shown snow levels for the tahoe basin and mono
County, may rise to 11,000 feet prior to the frontal passage and
During the period of heaviest precipitation saturday night and
Early sunday.
We do want to emphasize main-stem river flooding (truckee,
Walker, carson and susan rivers) is unlikely at this time due to
Ample reservoir storage relatively dry soil conditions. However
Those living near rivers, creeks and streams will want to remain
Aware of the forecasts through the weekend as river levels will be
On the rise.
Rain will intensify the northern sierra saturday, with light rain
Pushing across into western nevada. The period of highest snow
Levels and heaviest rain is focused from saturday night into
Sunday afternoon as the front moves through the sierra and western
Nevada. Potential is there for 6 or more inches of rain from
Western lassen county southward to along the sierra crest from the
Tahoe basin to mono county. Farther east, 2-4 inches are possible
In the tahoe basin to the foothills just west of highway 395, with
Up to an inch on the western nevada valley floors. There are a few
Factors which could produce more rainfall, especially if the front
Moves through the region slowly and warm rain processes increase
Precipitation efficiency as the front interacts with atmospheric
River.
Once the front passes snow levels should drop to near 5000 feet
Well north of i-80, near 6000 feet for reno-tahoe and near 7000
Feet south of highway 50. However the event will be ending as the
Snow levels drops, so significant snow accumulations may not occur
With this event.
High pressure is forecast to build over the sierra and western
Nevada monday and tuesday, with warm and dry conditions. Models do
Hint at a second warm moisture plume reaching the west coast for
The middle of next week. Brong
&&
.Aviation...
High pressure will bring vfr conditions, light winds and a high
Clouds through tonight. A fast moving system will bring period of
(roughly 6 hours) moderate to heavy rain/snow in the tahoe basin
And northeast california after 18z wednesday. Across western
Nevada rain and gusty winds are possible wednesday afternoon.
Conditions should fall to mvfr in rain for the tahoe basin and
Northern sierra terminals. Snow is unlikely to accumulate on
Runways below 6500 feet.
Much stronger winds will reach areas south of portola to lovelock
Thursday night and friday. Surface gusts may exceed 50 kts,
Especially at mammoth and perhaps reno-carson-minden. Certainly a
High potential for mountain waves, turbulent approaches and low
Level wind shear at all terminals.
A period of heavy rain is likely in the sierra and far western
Nevada, with high freezing levels, saturday night into sunday. Brong

The next system to move in from the pacific will arrive this
Morning with rain spreading south across the area during the day.
Heaviest rain will be from fresno north. A break in the
Precipitation will occur tonight and saturday.
The third...And strongest system will arrive saturday night and
Sunday. This system has the potential to bring heavy rain at times
To the san joaquin valley and adjacent foothills...Especially north
Of kern county.

The next sys to impact the region was just to the north...From the
Bay area to tahoe. This sys will gradually side south thru the day
With precip spreading south across much of the area this morning
Then into kern cnty in the mid to late aftn. Fairly potent pva
Movg thru the base of the parent upper low was pushing toward the
Central coast. This will interact with the front later this mrng
Into early aftn...And should produce some decent rain from fresno
North. The front will weaken later today as upper dynamics shear
East. Rainfall will taper off farther south in kern cnty...But
Think everyone there will get a few hundredths...With psbl
Exception of the deserts. Snow levels this mrng ranging from
7500-8500 north to south...And will rise about 1k ft as bulk of
Precip arrives.
The stalled and basically washed out front will linger tonite into
Sat. This will keep some residual precip mainly in the mtns into
Mid aftn sat. Then the third and possibly the strongest of the
Current series will be approaching the central ca coast. Rain
Should begin the the north around mce-ynp late in the afternoon or
Early evening. Rain may remain hung up for a while in the north as
The main shortwave and strongest dynamics push across norcal. Rain
Will then spread south quickly sun mrng and encompass most all of
Central ca in the aftn. Strong orographics set up across the srn
Sierra with this sys...And model qpf ranging from 3-6 inches from
Ynp south to kings canyon...Tapering off rapidly to a few
Hundredths in kern cnty. Sjv qpf will range from 1-1.5 inches from
Fresno north...Tapering off to around 1/2 inch from nlc/hnx/vis to
A few hundredths in the south end. Snow levels aoa 8k sun will
Drop to around 6500 ft in ynp sun nite. However by then much of
The precip will already be over.
For mon and into the new week...Models similar in yet another s/wv
Trof moving into norcal early tues...Sagging slowly south. Could
See some sct light precip from fresno cnty north beginning late
Tues. The remnant front becomes quasi stnry from mtr bay to ynp.
Thus some light showers fresno north into possibly early thurs.
Elsewhere dry. Fog chances in the sjv seem to be diminishing some
As the area remains in a weak trof and lots of clouds into mid
Week. A pattern chance is suggested late in the week with a high
Amp meridional flow developing...With a strong ridge building over
The eastpac/west coast states...And a deepening trof ern u.S. But
That is beyond the scope of this fcst attm.
