Areas affected...Central to eastern North Dakota
Concerning...Blizzard
Valid 081655Z - 082200Z
SUMMARY...
Ground blizzard conditions will likely increase in
coverage and duration over the next several hours for parts of
central to eastern North Dakota. While little accumulating snow is
expected, widespread visibility reductions between 1/2 to 1/4 mile
are likely and may persist through the mid to late afternoon hours.
DISCUSSION...Latest surface observations across the northern Plains
show winds increasing and temperatures rapidly falling behind an
east/southeastward moving cold front. Visibility reductions down to
1/4 mile have been noted where winds are strongest across
north-central ND, and regional web cams show periods of very low
visibility in open country. Observed sustained winds between 25-30
knots are on the high side of the anticipated wind speed
distribution per morning ensemble guidance. Hi-res solutions that
capture current winds speeds more accurately shows wind increasing
through the remainder of the morning and into the early/mid
afternoon hours before weakening gradually after 22-00 UTC.
While parts of central ND received light snowfall yesterday, most of
eastern ND received anywhere from 3 to 5 inches of snowfall over the
past 72 hours (per LSRs). Despite the age of the more substantial
snow pack, blowing snow model probabilities suggesting blizzard
conditions will become more widespread and sustained as winds
approach the 28-32 knot range (with lower thresholds for locations
that received light snow yesterday).
Current indications are that sustained winds across central to
east-central ND will fall within this range by late morning/early
afternoon, supporting areas of blizzard conditions with visibility
reductions down to 1/4 mile - especially in open country. Any gusts
above this range (which are likely for most of the outlined region)
will support periods of even lower visibility. Winds should
gradually abate late this afternoon, but pockets of blizzard
conditions may persist along the western periphery of the Red River
Valley where topographic affects may support breezier conditions.
