Marine Weather and Tides
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.

Discussion Afternoon showers are currently getting hung up on
the terrain, but that won't last very long. There is a lot of
instability and moisture in the area today, which is helping fuel
the storms. However, the wind shear is weak enough across the area
that none should be able to get strong enough to be severe, but
moderate rain showers, small hail, and wind gusts 30 to 40 mph are
possible this afternoon.
The rest of the week will be similar. A building ridge will cause
it to warm up, especially later this week. But a moist air mass
and moist southwest flow will keep dew points in the 40s and low
50s this week with afternoon showers and thunderstorms across the
area almost daily.
For area rivers, the rain is not going to be much of an issue,
however, the warming temperatures will be. Warmer daytime
temperatures and especially warmer overnight temperatures will
help the high elevation snow pack increase run off once again.|
Area rivers will rise again. Though the worst flooding on the
clark fork at missoula is likely over, flood waters around
missoula will once again rise to the moderate flood stage.
The flathead river is not yet showing signs of reaching flood
stage, but this area of northwest montana remains an area of
concern for potential flooding in the coming weeks.
Aviation Increasing showers this afternoon due to very moist
low levels. Wind shear is lacking though, so it is very unlikely
any storms will be severe. Terminals ksmn, kmso, and kbtm are most
likely to be affected by convection, whereas kgpi is much less
likely to be affected. Convection will weaken quickly after about
03z, but will not die out completely due to the upper level low
south of the region.

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.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. 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 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.
