Update
Issued at 1018 am cdt Mon mar 18 2019
trimmed some counties out of the dense fog advisory as GOES 16
shows coverage of dense fog gradually dissipating late this
morning. Will likely allow the rest of the advisory area to expire
as forecast. The latest radar imagery shows returns approaching
the canadian nd border late this morning with light snow being
pretty isolated in coverage. Expect isolated to scattered light
snow and flurries to build into the northern valley early this
afternoon as mid level gradually saturate.

Short term (today and tonight)
issued at 330 am cdt Mon mar 18 2019
patchy dense fog remains mainly east of the red river this morning.

Visibilities have dropped to one quarter mile or less at several
observation sites although coverage seems patchy. Areas around
devils lake have seen occasional reductions to around 1.5 miles.

A shortwave will traverse the region today, bringing a chance of
light snow and flurries to the area this afternoon. QPF amounts are
quite light among the mesoscale and medium range guidance thus we
will not see significant accumulations with todays system.

Accumulations will be limited, ranging from a dusting to one quarter
inch with the highest amounts possible in the devils lake basin.

High temperatures today will climb into the middle 30s across much
of the CWA with upper 30s for our eastern counties.

Quiet weather prevails through the overnight hours into early
Tuesday with low temperatures falling into the lower to middle
20s.

Long term (Tuesday through Sunday)
issued at 330 am cdt Mon mar 18 2019
mid upper level shortwave trough will be moving south Tuesday
morning, while another mid level shortwave (much weaker) passes
northeast of our CWA late Tuesday afternoon evening. An associated
weak cold front Tuesday night might bring a period of breezy
conditions Tuesday night Wed morning. Dry air mass in place aloft
will limit precip potential with these systems. Between these there
is enough of a temp recovery with low level westerly flow to support
highs above freezing Tuesday.

Wednesday-Friday: large scale mid upper level ridge builds over the
northern plains through these periods, with large scale subsidence
and deep dry air mass supporting dry conditions. Rising heights and
eventually SW low level flow (Friday) will moderate air mass and we
are expecting warming trend to eventually bring highs in the 40s to
almost all of our cwa. As usual, warmest temps (possibly as warm as
50 Friday) would be in our far east where forests are. Nighttime
lows will still fall below freezing (20s) and this sets the stage
for ideal (gradual) melt conditions. Due to daytime melting, low
level moisture should be available locally. Depending on nighttime
mixing, fog stratus could occur each night morning.

Saturday-Monday: significantly less certainty in these periods as
upper low is advertised to move out the the four corners region
across colorado and towards the northern plains. Significant spread
and uncertainty on how far north this system makes it and it's
track, and thus any impacts in our cwa. Solutions that favor
precipitation in our CWA show southerly flow and WAA with deep
moisture which could support more of a rain event (mix or snow
during nighttime periods?). Other end of the spectrum of guidance
would keep drier air aloft as ridge holds stronger, and this would
limit measurable potential. Obviously worth monitoring these
periods, but not enough confidence or consensus to begin favoring
one end of advertised solutions.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 630 am cdt Mon mar 18 2019
fog continues to affect ktvf and kbji with one quarter mile
visibility being reported through the morning. This will continue
through just before midday as the next weak system approaches the
region. Light snow will push through the region this afternoon
with a dusting to one quarter inch expected, especially within the
devils lake basin. Overall, ifr or lower CIGS prevail through much
of the TAF period.

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.
