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 Persistent moderate to heavy rainfall has allowed
many small streams and creeks to rise to near bankfull, or
slightly out of the banks from missoula, north to flathead lake
east of highway 93. Areas of greatest concern at this time, are
the streams and creeks flowing out of the mission mountains. The
steady rainfall is expected to become more showery in nature
within the next couple hours. However, water levels will likely
continue to rise, as water flows out of the mountains. If you come
to any roadways covered with water, do not drive through them,
and contact local emergency officials.
Conditions will be much drier and warmer Sunday and Monday, with
temperatures getting back above normal for this time of the year.
Rivers, streams, and creeks will continue to run at bankfull for
the next few days.
Besides warming up into the 80s on Monday, a relatively dry front
will move across the region. There are indications that the best
chance for any thunderstorm activity will be over southwest
montana later in the day. Also the wind gradient will tighten
later in the day which could be an issue for those desiring to
recreate on area lakes.
Expect warm, dry and seasonable conditions Tuesday and Wednesday|
before another frontal system brings showers and thunderstorms
Weather models have continued to show consistency in regards to a
cut-off low pressure system affecting the northern rockies Friday
and Saturday. This would bring widespread rainfall and cooler
temperatures to the region, therefore have increased the chance
for precipitation with increased confidence.
Many may be asking about the weather for the first week in
july... Long range guidance seem to suggest that it could start
off with a potential trough bringing unsettled weather and then a
gradual warm-up thereafter.
Aviation Light to moderate rainfall will continue to impact
area terminals across western montana through the afternoon and
evening. Breezy northwest winds will also develop this afternoon
for kbtm and kmso, but are not expected to be more than 20-22kts.
Skies will begin to clear overnight, with a few low hanging clouds
along the terrain through mid morning Sunday. Patchy fog is also
possible, particular around lakes and rivers.

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.

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.
