Marine Weather and Tides
Tupman, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

national weather service san joaquin valley - hanford ca
335 pm pdt Sun may 20 2018

Synopsis
A chance of afternoon and early evening thunderstorms will
continue to exist over the higher elevations of the sierra each
day through Wednesday. Otherwise, dry weather will prevail over
the central california interior through the middle of next week.

Winds will be gusty at times through and below the mountain
passes.

Discussion
Weak upper level disturbance moved east of the district today
and placing widespread convection over the great basin. While
convection over the crest of the sierra nevada has materialized
this afternoon, the extend is greatly diminished from Saturday's
coverage. Therefore, now that the district is in between
disturbances, afternoon convection will remain at minimal levels
before a deeper uppe low pushes into the region overnight. Models
continue to show high confidence levels on placing the upper low
over central california by Monday morning with possible wrap
around activity during the day. With very low uncertainty in the
ensemble solutions, will keep probability of measurable
precipitation at high chances to near likely categories for
Monday's event. Furthermore, the onshore flow has placed the
marine layer well above 2000 feet msl as cool air continues to
filter into the san joaquin valley. While convection is likely
over the sierra nevada, convection may be slightly more difficult
to obtain over the valley under cooler conditions.

Again, current model timing has the upper low over the district
on Monday morning before sunrise. Confidence in the track and
timing still decreases as the upper low attempts to move out of
the area and into the desert southwest. Again, as mentioned,
precipitation will be confined to the upper terrain of the sierra
nevada with very slight chances of reaching the valley. Will keep
the probability of measurable precipitation at minimal levels and
concentrate on mountain precipitation and thunderstorm activity.

Current model progs have the best instability over northern
california on Monday, but will mention thunderstorm down into the
foothills and possibly the areas around the valley-foothill
interface.

Tuesday may have lingering effects as the upper low shifts into
the desert southwest and closer to las vegas. The position of the
upper low on Tuesday may favor more widespread convective activity
across central california (moisture dependent). Current model
moisture progs and satellite precip-water imagery does not favor a
subtropical moisture connection for the early week event.

Therefore, will keep precipitation accumulations at light to
moderate levels during the convective activity. Models then move
the upper low out of the region toward the middle of the week as
the convective threat diminishes under a southwesterly flow aloft.

At that time, a weak ridge over the west will provide a brief warm
up ahead of another disturbance over the pacific that may affect
the area toward the end of next week. While models do attempt to
move the next upper low closer to california near the end of the
week, confidence is very low on the track as it approaches the
state. Yet, while models are having a difficult with the position
of the upper low, they continue to indicate that a low could form
during the latter part of the week. In the meanwhile, will keep
the district dry as temperatures and winds go through their
roller-coaster ride of highs and lows.

Aviation
A slight chance of possible thunderstorms with local MVFR ifr
conditions may occur over the higher elevations of the southern
sierra nevada between 19z today and 03z Monday. Otherwise... A good
chance exist of possibleVFR conditions prevailing across the
central ca interior during the next 24 hours.

Air quality issues
None.

Certainty
The level of certainty for days 1 and 2 is high.

The level of certainty for days 3 through 7 is medium.

Certainty levels include low... Medium... And high. Please visit
