Short term (today and tonight)

the winter storm remains on track for southern minnesota and western
wisconsin. The hazards that were in place yesterday were left
untouched as the adjustments were mainly focused on tweaking the
northern gradient and adjusting the thermal profile from the albert
lea toward eau claire areas.
Early this morning, the deepening surface low was located over
extreme northwestern missouri and will continue to deep and lift
into iowa today. Meanwhile, the main precipitation band is taking
shape from nebraska through northern iowa, and is lifting into
southern mn. Albert lea continues to report rain falling, but to
the east a cooler thermal profile has allowed a changeover to snow
The hi-res models now cover the storm as it moves through and has
only increased our confidence in the forecast. The heaviest band of
snow of 8-14" remains in the same place; from near fairmont through
red wing, menomonie, and ladysmith.
The twin cities metro still looks to have a tight snowfall gradient.
With the rap, hrrr, and hopwrf now covering the temporal period of
the storm, confidence is increasing that the southeast metro will
see 6"+ of snow and the gradient may be a few miles northwest of
earlier expectations. Did adjust the snow amounts upward along the
northern gradient. Further aiding in this decision was the fact that
overnight lightning across the state of iowa wasn't all that
widespread. In addition, we've been watching a west to east band of
snow developing from canby through the metro toward menomonie. This
will produce some light snowfall this morning before the main event
ensues for the metro mid morning, with the heaviest snow expected
The hrrr and rap show the potential for a heavy snow band to impact
the metro mid afternoon leading up to the evening commute. This
band could have 1-2" hr rates given the strong mesoscale forcing
associated with it and make for a very slow commute this evening.
The winds will continue to strengthen as the low moves through iowa
today, with blizzard conditions developing from south and west of
mankato. Again, the heaviest snow will arrive in far southern mn
early this morning, with the heaviest period of snow expected later
today in the metro and western wi. The morning commute will be
impacted across far southern mn by the onset of the snow, while the
metro and wisconsin will see minimal issues this morning for the
commute. The afternoon commute will be a completely different

no significant changes in the extended. Blended guidance shows a
slight cool down in the wake of today's storm, with highs in the mid
to upper 20s Tuesday and Wednesday, but this is still about 2 to 5
degrees above the seasonal average for late january. A weak
shortwave will embedded in northwest flow will slide southeast|
across the region Tuesday night, and this should be strong enough to
produce some clouds, but not enough to precipitate other than
perhaps a few flurries.
Upper level ridging will ensue for Wednesday night and Thursday,
keeping the region dry and mild. On Friday highs could reach the
lower 40s across the region as the low level thermal ridge advects
across the region. A cold front will follow Friday night with cold,
but not bitterly cold temperatures for the weekend into early next
week. No significant precipitation is expected at this time.

southern mn through western wi still expect major impacts with
heavy snow and strong winds developing today. Kmkt and keau look
to be most impacted but confidence is increasing the kmsp will get
significant snow mainly this afternoon and impact the afternoon
and evening. A band of moderate snow is just developing across far
southern mn and will lift north through the morning as it
intensifies. Wind speeds will increase with it as well, aiding the
reductions in vsby forecasts. Rwf will see some lighter snow along
the gradient, while axn and stc avoid the snow, but deal with ifr
Kmsp... Snow will intensify late morning with the heaviest coming
down this afternoon. 1 4sm visibility is possible at times in the
heaviest snow band for this afternoon.

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.
