Update
Issued at 641 am cst Sat feb 23 2019
snow continues to push east and northeast this morning. Much of
the activity is now in northwest minnesota with only light snow
lingering to the west of the red river. Snow will continue moving
through northwest minnesota this morning with up to 2 inches still
possible in the red lakes and lake of the woods regions.

Short term (today and tonight)
issued at 315 am cst Sat feb 23 2019
light to moderate snow continues to work it's way across the cwa
this morning. Still looking at an additional 1 to 2 inches, mainly
north of interstate 94 with a few areas possibly seeing up to an
additional 3 inches in the lake of the woods area.

The upper low that is driving the current system will continue
moving eastward across the central high plains through the morning.

We will see a reprieve through much of the afternoon, evening, and
into tonight. Snow chances increase once more on the northwest side
of the low as it moves into the midwest and southern great lakes
region. Any snow accumulations are expected to remain less than one
inch. Northerly to northwesterly winds develop after midnight and
quickly increase through the early morning hours in response to a
rapidly tightening pressure gradient. Strong CAA prevails as a result
with temperatures dropping sharply after midnight.

Long term (Sunday through Friday)
issued at 315 am cst Sat feb 23 2019
as the stacked low pressure system moves into the great lakes by 12z
Sunday, the pressure gradient really tightens up across eastern
north dakota and the northwest quarter of minnesota. There is pretty
steady 850mb cold air advection throughout the day Sunday with a
nice pressure rise fall couplet. Main question is how fast wind
speeds will increase late Saturday night into Sunday morning. Seems
like as the low moves up into the great lakes somewhere in the
neighborhood of 09-12z Sunday, winds do jump across the fa, and
continue there throughout the day Sunday. Will therefore use 09z
Sunday as the start time for a winter storm watch for eastern north
dakota into most of adjoining northwest minnesota. The watch would
be for potential blizzard conditions.

Will have to keep an eye on the timing though, as there may be a
potential with some initial cold advection to kick the increasing
winds off a tad earlier (possible 06z Sunday). Still looking at the
potential for 40 to 50 mph wind speeds from 09z Sunday until 00z
Monday. Wind speeds really begin to drop quickly by late Sunday
afternoon into Sunday evening. However, with quite a bit of lofted
snow, it will probably take longer than expected for visibilities to
increase again. Plus with darkness coming around or just after 00z,
that tends to make visibilities seem lower too. Another thing that
always makes a difference with potential blizzard events is falling
snow. Sometimes models tend to underestimate the light falling snow.

See that most models do show some very light snow at least into
Sunday morning. Even light falling snow can compound visibilities.

Advisory criteria wind chills then move in Sunday night. Luckily
winds should decrease quickly and prevent wind chill warning
criteria values. Wind chills may also dip down into advisory
criteria Monday night through Wednesday night. As far as snow
chances, still looks like a minor event Tuesday into Tuesday
evening, with an inch or two of snow. Then there could also be
another quick moving system for late Thursday night into Friday,
with a few inches possible across southern and eastern areas.

Aviation (for the 12z tafs through 12z Sunday morning)
issued at 537 am cst Sat feb 23 2019
ifr CIGS prevail this morning, becoming MVFR for sites along and
west of the red river. For kbji and ktvf, ifr conditions are
expected to persist as light snow is expected through the early
afternoon. Winds will increase heading into the overnight hours
with blowing snow becoming a hazard heading into Sunday.

Restrictions to visibility are likely after midnight tonight with
wind gusts of up to 40 knots out of the northwest.

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.
