Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

Discussion At 9 am mdt upper low was centered in western utah
and moving north. This track will bring the low closer to our cwa
than forecast earlier. Will update higher pops in southern idaho
zones this afternoon as showers approach from the east. As of 9 am,
showers were already increasing in southeast idaho and moving
toward the wnw. Namnest model shows a distinct wind shift to
southeast this afternoon as the showers approach. Will include
this in the morning update which should be available by 0945 mdt.
Aviation GenerallyVFR with isolated MVFR and areas of mountain
obscuration in showers. Isolated thunderstorms this afternoon.
Showers will diminish overnight. Surface winds, north-northwest
5-10kts. Winds shifting to southeast 10-15kts at ktwf and kjer
around 23 18z, and at kboi around 23 22z, with showers after the
wind shift. Winds aloft to 10k feet msl, northerly 20-25kts.
Short term... Today through Sunday... A few showers noted over the
forecast area this morning, with most areas seeing diminished
activity. The area of low pressure bringing the moisture from the
desert southwest will begin to lift northward today towards the
northern plains. This will bring some wraparound moisture into
western idaho through the afternoon, with isolated thunderstorms|
favored. Additionally, a tightened pressure gradient is expected
resulting in gusty wind through this evening, especially across
eastern oregon. A brief reprieve in moisture anticipated tonight
and into Friday morning as the area of low pressure moves further
east. However, another area of low pressure will be right on its
heels, moving into the area by Friday afternoon. Moisture looks
decent with this system, with enough instability to bring a return
of isolated afternoon thunderstorms. This same area of low
pressure will move south down the pacific coast through Sunday,
continuing the presence of cool, wet, and unsettled conditions.
Temperatures anticipated to remain 5 to 10 degrees below normal.
Long term... Sunday night through Thursday... Upper level low moves
across the great basin Sunday night through Tuesday bringing
widespread showers along with afternoon thunderstorms. Models
diverge greatly thereafter with how a shortwave ridge briefly sets
up Wednesday and Thursday. Either solution keeps us active with a
threat for showers and thunderstorms during these periods so the
differences are not of much concern for this time period.
Temperatures stay below normal but rise steadily each day.

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 L-36.com 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.
