Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Discussion Westerly flow will continue across the idaho and
montana as broad high pressure centered near the nevada utah
border slowly grows stronger. This will lead to a gradual warming
trend through the weekend under an abundantly sunny sky. Typical
afternoon breeziness is expected with perhaps stronger winds on
Sunday due to the passage of a weak, dry canadian cold front that
clips NW montana. In fact, the breezy winds from this feature may
keep the atmosphere more turbulent than normal Sunday night and
lead to less cooling in the valleys for Monday morning. And while
moisture is lacking, some cumulus cloud development seems possible
along the frontal boundary Sunday afternoon with the slightest of
chances for a weak thunderstorm.
Southerly flow aloft will begin to slowly seep monsoonal moisture
northward into idaho on Monday, resulting in a progressively
growing threat for convection by Monday afternoon. The chances
Monday will be best across central idaho and far SW montana. But,
steadily increasing moisture overnight will subsequently lead to
the threat for nocturnal thunderstorms. By Tuesday the models are
showing an extremely moist air mass across much of the northern
rockies with precipitable water values running in the 80th
percentile. This anomalously high amount of atmospheric moisture
when combined with the added instability of a passing weather|
disturbance will lead to widespread thunderstorms by Tuesday
afternoon. It seems quite likely that these storms, at least
initially, will have slow forward motion and thus could present
the threat for very heavy rain. This threat is likely to extend
into Wednesday, though the storms do appear to pick up a little
bit more speed. Either way it does seem quite likely that the
northern rockies region will have a chance for some much needed
rainfall. Though we will still have to contend with the threat for
gusty winds and lightning with these same storms.
The chance for thunderstorms is forecast to decrease significantly
by Thursday as drier air shifts the monsoonal moisture south and
east. Warm temperatures (a little above normal) and breezy
afternoon winds remain in the forecast through the rest of next
week and likely into the weekend.
Aviation Winds are increasing this afternoon with a tightening
pressure gradient. These winds will generally be westerly between
10-20 kts and gusts up to 25 kts through around sunset. Latest
satellite imagery show wild fires in the region becoming more
active in response to warming temperatures and increased winds, so
wildfire smoke may create impacts to visibility.

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.
