National Weather Service Twin Cities/Chanhassen MN
552 PM CST Sat Mar 11 2017
.SHORT TERM...(This evening through Sunday)
Issued at 345 PM CST Sat Mar 11 2017
Although confidence has increased enough to warrant a winter storm
warning along and southwest of the Minnesota River Valley, there
remains uncertainty on how much the drier air will play a role
during the onset of snow on Sunday. First, there is no question
that most of central and southern Minnesota, and west central
Wisconsin will see light snow before Monday afternoon. The main
question is how fast does the very dry air mass overhead begin to
saturate the low levels of the atmosphere and allow snow to fall
to the surface. Dew points this afternoon are slightly higher
than yesterday, but humidity levels remain very dry in the 20-30%
range in the boundary layer. Just as a previous winter storm that
had a very sharp gradient of where the snow fell, to nearly
nothing on the northwest side, this system has similar
characteristics. However, the orientation of the sharp snow line
is different. Another aspect to this storm is the relatively
short period of strengthening Sunday before the main forcing moves
south/southeast of Minnesota by Sunday night. This forcing is
associated with a strong thermal gradient oriented from west
central to south central Minnesota Sunday morning, through Sunday
afternoon. This is where the best frontogenesis, omega and the
dendritic growth zone coincide.
Initially the dry air mass needs to saturate which might be
easier in southwest Minnesota due to the current system leaving
behind some moisture in the boundary layer. However, further to
the east/northeast the air mass may take a few hours to saturate
leading to lower confidence on snowfall amounts. The dendritic
zone does last longer further to the east across south
central/east central Minnesota Sunday afternoon, but the forcing
is weaker and may hold off on accumulating snowfall until the late
afternoon. Another aspect to this storm is the concern with
snowfall ratios which initially will be 18/20-1 in eastern
Minnesota, to 15/17-1 in southwest Minnesota. These numbers will
rise during the day, so the combination of snowfall ratios and qpf
amounts will be critical on snowfall totals, especially Sunday as
the atmosphere saturates in the boundary layer.
.LONG TERM...(Sunday night through Saturday)
Issued at 330 PM CST Sat Mar 11 2017
Longer term concerns remain placement of the heavier snow band and
overall headline resolution.
Model trends indicate heavier snow will be ongoing over south
central MN during the evening. Best vertical velocity in the
dendritic growth zone remains over the southwest metro by late
afternoon and shifts into south central MN mainly after 00z Mon. We
do feel model qpf may be a bit high...especially on the NAM...which
also seems to shift heavier snow band farther to the northeast.
Also...adjusted the SLR values during the evening as well... with
18t to 20:1 a bit high when compared with the COBB and other model
trends...especially to the south. A more 14-17:1 ratio looks be
better here. Meanwhile...the 12z GFS holds onto its snow band
placement...mainly to the southwest. Looking at the GEFS probability
trends last few runs...they have shown pretty good continuity with
the >6 inches snow accumulation in 24hrs...which places it along the
Minnesota River Valley region. Still have time to monitor one last
model run to finalize over all headlines. The bulk of the snow
should occur before 12z Monday across the area...with some lingering
light snow possible over the eastern cwa Monday morning. Wind
concerns appear minor at this time with wind gusts around 20 to 25
mph expected at the tail end of the accumulating snow.
We see cooler air to follow the system through Wednesday with a
gradual warming trend...above normal into next weekend. The
deterministic runs diverge some on how much warm air lifts northeast
into the area...ahead of the next trough. It looks warm enough for
at least a rain/snow mix...if not all rain developing during the day
Friday the surface cold front.
&&
.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 552 PM CST Sat Mar 11 2017
Model agreement is quite high with snow coming in Sunday, with one
thing of note being that the hrrr is coming in an hour or two
slower than the GFS/NAM, which makes sense given very dry initial
airmass. As a result, not much was changed with existing TAFs
other than to delay snow onset an hour or two. Heaviest snow still
expected at RWF, with vis 1/4sm or less in snow at times possible
there 18-22z. All other terminals look to only drop as low as
3/4sm in snow with heaviest snow running down the MN River toward
AEL.
KMSP...High confidence in forecast, including with arrival of
snowfall Sunday. Expect snow to start within 90 minutes of what
current TAF has. Only thing that may be different is we may come
out the gate with 1sm vsby as opposed to current MVFR vis
indicated. Heaviest snow, with rates between 3/4" and 1" per hour
expected between 20z and 1z. These kind of rates will likely
necessitate an AWW as the event draws closer. Expecting snow
totals in the ballpark of 4" at MSP with this event.
