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.

current satellite and surface weather observations show clear
skies across all of western and central north dakota as the low
stratus deck over the james river valley rapidly dissipated this
evening. Therefore, the sky cover forecast has been manually
edited to depict clear skies across the area. Flurries have also
been removed from the forecast for the remainder of tonight. In
addition, the latest observations were also blended into this
Update issued at 739 pm cst Sat nov 17 2018
decreased overnight lows for tonight using the minimum forecast
lows of all models as current observations show temperatures
already nearing or below the previous forecast lows. In addition,
satellite imagery shows clear skies across western and central
north dakota as the stratus deck over the james river valley has
rapidly dissipated. The clear skies combined with light winds
should allow for sufficient radiational cooling. Expect most areas
to drop down to the lower single digits.
Update issued at 542 pm cst Sat nov 17 2018
current satellite and surface weather observations continue to
show a low stratus deck oriented from north to south across
central north dakota, moving eastward into the james river
valley. Flurries are also being observed out of this stratus deck.
Manually edited the sky cover grids through 06z to account for
observed trends, and also added a 30 percent chance of flurries
through 06z for all areas expected to be underneath the stratus
deck. No other notable changes were needed with this forecast
Short term (this evening through Sunday)
issued at 238 pm cst Sat nov 17 2018
current surface analysis places cold high pressure over the
dakotas. Upper level analysis places modest trough stretching
from the northern plains southwestward towards the great basin. A
thin stratus deck remains over the area producing some flurries,
though it is trying to erode on the west side.
For the rest of this afternoon into tonight... Stratus deck will|
continue to erode but gradually push east through the afternoon
into the evening. If for some reason the stratus lingers into the
overnight low temperatures may need to be adjusted up, as they
were adjusted down a bit from guidance given the fresh snow cover
and anticipated clearing skies. Later tonight, a weak but fast
moving clipper system will start to make its approach with cloud
cover starting to develop over northern locations.
On Sunday... Cloud cover will be on the increase as clipper
continues its approach, with snow chances spreading from north to
south. Snow chances linger overnight across the area. There will
also be some chances of freezing drizzle, mainly over western and
south central portions of the state, as soundings suggest there
may be a lack of ice to work with.
Long term (Monday through Saturday)
issued at 238 pm cst Sat nov 17 2018
precipitation chances will linger into Monday morning.
Upper ridge over the pacific coast will gradually work its way
towards the east through the week, passing over our area on
thanksgiving morning. With the exception of a weak system zipping
through the area on Monday, dry conditions are expected through
Friday. A northeast southwest temperature gradient will remain
through the period, though an overall warming trend is expected
through Thursday. Temperatures are then expected to cool heading
towards the weekend in the wake of the ridge.
Aviation (for the 06z tafs through 06z Sunday night)
issued at 1028 pm cst Sat nov 17 2018
an area of scattered light snow showers will begin moving into
northwest north dakota late Sunday morning, likely affecting kisn
by the early afternoon. Light snow will spread south and east
through the day, likely affecting kmot, kdik, kbis, and kjms during
the late afternoon and early evening hours. In addition, MVFR
cigs are expected to develop across most of western and central
north dakota Sunday afternoon and evening.

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.
