Marine Weather and Tides
Moorefield, NE

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.

area forecast discussion

320 am pdt Mon may 21 2018

Synopsis
Afternoon and evening thunderstorms possible over higher terrain
much of this week. Seasonal temperatures continue across the
region.

Discussion
Clear to partly cloudy skies across the region early this morning.

Radar showing some light showers across the higher elevations of
the northern sierra south of tahoe. Onshore pressure gradients
have relaxed compared to 24 hours ago and winds at travis have
also decreased, so not looking favorable for a stratus intrusion
into the sacramento region this morning.

Current temperatures range from the mid 30s to mid 40s in the
mountain valleys to the 50s to lower 60s elsewhere.

Satellite imagery shows the latest low closing off to our south
over central california while a strong vort presently over nw
california is dropping southward. A few light showers may drift
down into the motherlode and northern san joaquin valley this
morning as vertical motion increases across the southeast portion
of the CWA and forecast soundings show rapid moistening. This area
will also see potential for some showers late this afternoon and
evening as decaying activity from the sierra drifts southwestward
toward the san joaquin valley.

Closed low forecast to slowly lift northward through the great
basin Tuesday and Wednesday as the next upstream low approaches
norcal from the west. Shower and thunderstorm activity expected to
be mainly diurnal and limited to higher terrain.

Next system forecast to bring an upswing in shower activity later
Thursday as it approaches the coast near the bay area.

.Extended discussion (Friday through Monday)
guidance shows an upper level low off the ca coast approaching
interior norcal late this week. The upper low will push inland on
Saturday. Forecast models indicate enough instability for a threat
of showers and afternoon evening thunderstorms over higher
terrain, and possibly in the northern sacramento valley. Drier
conditions expected early next week as upper level system moves
into the great basin. Daytime highs expected to remain near
seasonal normals through the forecast period with valley
temperatures in the upper 70s to mid 80s, and 60s to 70s over the
foothills and mountains.

Aviation
MainlyVFR conditions over interior norcal next 24 hours except
MVFR ifr conditions possible in showers and thunderstorms over the
northern sierra nevada after 18z Monday. Gusts up to 25 kts in
delta until 00z Tuesday, increasing to 30 kts overnight. Winds
less than 15 knots at TAF sites.

Sto watches warnings advisories None.

GOES Local Image of CentralWestCoast    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
