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.

Made some minor adjustments to pop's for the morning and afternoon
based on current trends and the latest high-resolution models.
This tended to result in somewhat lower pop's early on for the
central and western zones. High-resolution models trending toward
better chance of convection over yellowstone county and adjacent
areas after 2-3 pm. Bt

satellite imagery shows upper low sagging into northern wy with
region of diffluence lifting through northeast wy. Showers with a
few lightning strikes continue to develop near sheridan and across
far southeast mt. There have also been a few showers in our
northeast. To the west, drier air and downsloping w-nw winds have
yielded a mostly dry night.
More non-severe showers and thunderstorms are in store today. The
activity should have greatest coverage in our east along
convergent mid level trof, and this is what the latest cams are
suggesting. We will see mainly diurnal and more isolated
convection in our west underneath cyclonic flow aloft with weak
ascent provided by trowal as the upper low moves to the southeast.
Western showers should end around sunset, but expect some
activity to persist overnight in our east with lingering ascent
and elevated instability.
Monday will be dry warmer as the low finally shifts to the central
plains and ridging builds from the west. Areas along the dakotas
border will probably see a few weak showers and perhaps a
thunderstorm, but the instability will be competing with a
developing subsidence inversion as heights rise, so there is some

Monday night. Greatest forcing will exist across northern montana,
but we should see a few showers by late evening in our northwest,
then across more of our western CWA late Monday night, perhaps
reaching billings along the cold front before sunrise.
Temperatures will remain below normal with highs mostly in the
70s today. Temps will get back to the 80s Monday.

little in the way of changes with latest model runs.
A weak cold front still on tap for Tuesday. Models continue to
produce limited qpf, do seem to hint at a little more each run, so
have continued with slight pops at this time, especially when
consider boundary layer moisture in place.
Dry conditions will prevail Wednesday and much of
Thursday ahead of the next pacific trof that moves in late
Thursday night Friday. Models continue to show another active
pattern through the remainder of the period, as a low drops down
into the northern rockies. Models do look a bit drier than
previously advertised, but still active. Aag
Isolated to scattered showers and thunderstorms are on tap for
all routes once again today. Localized MVFR to ifr conditions are
possible in heavy rainfall. Occasional mountain obscuration can be
expected through today. Otherwise,VFR conditions will prevail

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.
