Marine Weather and Tides
Dover, ID

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.

Scattered rain showers will linger over the idaho panhandle this
evening, while much of central and eastern washington remains
dry. Summer conditions return Sunday, with sunshine and high
temperatures in the 80s. There will be a chance of thunderstorms
Monday morning, followed by gusty winds in the afternoon as a
strong cold front moves through the region. Mild weather Tuesday
and Wednesday will give way to the chance for showers later in the

Satellite reveals an upper low pressure circulating over montana
this afternoon. Wrap-around moisture feeding into north idaho and
northeast washington will maintain a chance of showers and a small
chance of a thunderstorm this evening over the panhandle... With
generally clouds and a few sprinkles possible over the northern
washington zones. Much of the cloud cover over the washington
zones will decrease after sunset... But clouds may remain well into
Sunday morning over the panhandle as the decaying upper low slowly
crawls away to the east. Then a sharp upper level short wave ridge
will take over for Sunday with sunny conditions over the
washington zones and gradually clearing skies over idaho. A weak
surface thermal trough will set up over the basin and promote high
temperatures above average over most of the region. Tomorrow
promises to be a pleasantly warm early summer day for the area.

Meanwhile... Off the coast satellite also indicates an offshore
closed low in the gulf of alaska getting set to hurl an appending
short wave trough into the northwest... Depicted by the elongated
region of enhancement approaching vancouver isle this afternoon.

This wave will carry a good moisture feed with it and move into
the cascades late Sunday night. Two threats are wrapped in this
imminent frontal passage. The first will be a chance of showers
and morning thunderstorms beginning on the cascades in the wee
hours of Monday morning and tracking into the northern basin and
northeast mountains during the daybreak morning hours through 10
am. These storms will be generated by elevated instability but the
moisture feed will be sufficient to produce a few hundredths to a
tenth or so inch of rain over many locations north of highway 2 to
the canadian border. South of highway 2 the primary issue will be
breezy to windy conditions beginning in the morning and increasing
during the day. Not much rain is expected over the basin with this
system..If any. So Monday will bring a threat of rapid fire
spread in the dry range land with breezy and dry
conditions... Despite the fact that temperatures in this post-
frontal air mass will return to near normal. Fugazzi
Monday night through Saturday: mostly dry weather is forecast
through mid-week, before another threat of showers and
thunderstorms moves in especially around the mountain zones.

Monday night a shortwave trough exits through the northern
rockies. Shower chances will mainly linger near the cascades crest
and canadian border. Winds will remain breezy through the evening,
before decreasing overnight. Tuesday and Wednesday are forecast to
be dry with a flat ridge building in. However some clouds are
expected to increase from the west later Wednesday into Wednesday
night as a weak shortwave slips in. Limited shower chances come
to the cascades and idaho panhandle mountains too, but these look
rather light if anything falls at all. If the shortwave ends up
being a little strong some limited shower chance or just sprinkles
may also be squeezed out over the basin valley locations. That
shortwave will start to carve out a broader trough over the west
and between Thursday and Saturday additional shortwaves entering
will start to increase precipitation chances across a broader area
of the cwa. Thursday the main risk remains in the mountains, but
it looks breezy across the region. Then between Thursday night and
Saturday shower and thunderstorm chances expand throughout much
of the region, except for the deeper columbia basin and lower lee
of the cascades. Best chances will be during the afternoon evening
hours Friday and Saturday. Some impacts are possible from
thunderstorms. Temperatures will be near to slightly below normal.

18z tafs:VFR conditions are expected as a high pressure ridge
builds into the region. Some scattered showers today expected for
kcoe. Winds will be be breezy today through the cascade gaps and
into the basin and keat-kpuw-klws could see gusts 20-25 kts this
afternoon. Jdc

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
