Update
Issued at 938 am cst Wed dec 12 2018
extended the dense fog advisory until 11am for areas including
and north of grand forks as visibilities down to a quarter at
hallock and grafton as of 9am. No other changes needed at this
time.

Update issued at 633 am cst Wed dec 12 2018
the western edge of the fog around devils lake has lifted
somewhat and satellite is showing some low cloud clearing eastward
toward valley city. I do think in time most areas will see the fog
lift. Timeline of that to be determined. Dense fog advisory will
remain until 15z. If areas need it to be extended it can be
evaluated at that time.

Short term (today and tonight)
issued at 311 am cst Wed dec 12 2018
widespread dense fog covers much of eastern nd and the rrv and
will maintain dense fog advisory out thru 15z. Hrrr model does
indicate breaking up of the low level moisture 15-18z period... So
would expect improvement in that period. But certainly areas of
dense fog may persist beyond 15z and if needed the advisory can
be extended. Precipitation band has fallen apart, but still
getting some light returns on radar. These are mostly mid clouds.

Temps today will climb into the mid 20s to low 30s. Next short
wave trough to move east thru the area tonight. The 500 mb trough
remains neutral to positively tilt unlike the one on Tuesday
night. Various short range models so a disorganized area of
precipitation moving thru the area tonight. Soundings suggest deep
enough moisture thru the profile for light snow, but cannot rule
out some sleet or freezing drizzle. Use of top down shows
limited freezing rain chances due to deeper moisture profile with
the short wave. Temps rise too overnight with many areas rising
to near freezing. Due to expected light nature of the
precipitation do not anticipate banding frontogenesis aiding in
precipitation amounts and snowfall will be one half inch or less.

But these waves can be tricky so will need to monitor for changes
with new 06z and 12z model data.

Long term (Thursday through Tuesday)
issued at 311 am cst Wed dec 12 2018
quiet, mild weather takes hold for the majority of the next week.

Much of the forecast focus is on temperatures through next week as
the region remains fixed in progressive split flow between two jet
streams (north and south).

For Thursday night through Saturday, milder air returns as split
flow aloft prompts strong ridging aloft over the canadian and 850 mb
temperatures rise into the 5-10c range. Sunshine and Saturday's
strong warm air advection ahead of a passing sfc trough will
influence temperatures notably, with high temperatures expected to
range from near the freezing mark along the international border to
the lower 40s along the sd border on both Friday and Saturday. Could
see some small precipitation chances along the international border
Saturday afternoon and night, associated with the passing sfc
trough. With 950-850 mb winds in the 20s to 40s on Saturday and
Sunday, could see some gusts and or breezy conditions with daytime
pbl mixing as well.

Temperatures dip a bit back toward near normal values on Sunday as
breezy northwest winds and a progressive longwave trough aloft dig
through the northern plains. For early next week, probabilistic data
suggests a return back up to fairly mild daytime temperatures
(peaking near or above the freezing mark) as upper ridging persists
for much of the western two thirds of the conus.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 633 am cst Wed dec 12 2018
pockets of lifr vsbys and CIGS thru 15z, ESP gfk far areas. Trend
will be some improvement thru the late morning and midday but as
usual the timing of how fast that occurs is uncertain. Same goes
for the other sites such as tvf and bji which are not in dense fog
but low clouds. South winds 10 to 15 kts. Tonight will see a
period of light snow or mix.

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.
