Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
327 PM CDT Fri Mar 31 2023

.SHORT TERM...(This evening through Saturday night)
Issued at 327 PM CDT Fri Mar 31 2023

KEY MESSAGES:

- Blizzard Warnings expanded eastward into Wisconsin tonight.

- Several hours of heavy snow with rates of 1 to 2.5 inches per
  hour, combined with wind gusts of 40 to 50 mph, will lead to
  whiteout conditions.

Showers and thunderstorms are quickly developing across the area
this afternoon as elevated instability continues to build northward
and intense dynamics begin to advance east to the Upper Midwest. A
few severe thunderstorms have been observed as far northwest as
eastern SD this afternoon. A few severe cells are possible across
Minnesota into the early evening capable of large hail.

As the evening progresses, colder air will wrap in and precipitation
will transition to widespread heavy snow. As the cyclone rapidly
becomes negatively tilted, intense bands of snow will form across
eastern/southern MN and WI later this evening. HREF probs for 1
inch/hr rates are near 100 percent and are even greater than 50
percent for 2+ inches/hr. Thus, there could well be 2 to 3 inch per
hour rates at times and snow will pile up very quickly. The shield
of snow will be slow moving as the system wraps up to the southeast
and several hours of intense snow are likely. Because of these
factors, total snowfall amounts have lower confidence than usual,
but chances for exceeding 8 inches are increasing markedly. The
ceiling could be high as the new snow probabilities illustrate
(10-12+ inches), but this is dependent on intense snow rates for at
least a few hours. Time is the limiting factor as the snow shield
will sink southeast overnight and end before dawn. An intense, but
relatively short system will lead to severe impacts tonight.

Winds will increase steadily through the evening with some gusts of
40 to 50 mph. Widespread blowing snow will result and whiteout
conditions will make travel dangerous or impossible. With a high
probability of near zero visibility in falling snow alone given the
winds expected, the Blizzard Warning has been expanded eastward
across much of the CWA into Wisconsin. This includes the core metro.
Any blowing snow will make conditions even worse.

Conditions will improve quickly after the snow ends. Winds will
diminish as well. Saturday will be a rather tranquil day with plenty
of sun and light winds by afternoon.

.LONG TERM...(Sunday through Friday)
Issued at 327 PM CDT Fri Mar 31 2023

KEY MESSAGES:

- Strong warm air advection on Sunday may fairly widespread highs of
  at least 50 degrees for points south and east of the Twin Cities.

- Another multi-faceted spring system by the middle of next week as
  seasonably cool temperatures stick around.

A shortwave and associated low will pass along US/CAN border on
Sunday. The good news is that most should stay dry, but there is a
non-zero chance for some light precipitation through early afternoon.
Southerly winds ramp up in response to the passing low pressure and
will usher in much warmer temperatures. Highs will range between mid
to upper 40s for most, but areas across central and western MN may
stay in the upper 30s to lower 40s due to lingering snow pack.
Monday shouldn't be much different other than a few degrees cooler.
High pressure will linger to our west ahead of the next strong low
pressure system begins to deepen in the Plains.

This system will be the next one on our doorstep for next Tuesday
into Wednesday. There's good model agreement that another potent
Spring low pressure system will eject out of the northern/central
Plains and lift into Ontario. Again, the issue with this system will
be determining P-Types, given the time of year systems tend to have
strong thermal gradients. Where the thermal gradient sets up will be
largely determined by the track of the low. The location of this
gradient will determine where the rain/snow line sets up. Some
solutions are more dynamic with a sub 980mb low through western
MN/eastern Dakotas while others are less dynamic with a weaker low
passing through eastern MN. Guidance also suggests the potential for
a dry slot to cut into QPF amounts along the track of the low.
Ensemble guidance suggests that the bulk of the snow from that
system will miss us to the north and west, but again, we're several
days out.

Temperatures will remain seasonably cool with highs in the 30s and
40s most of the week, with a potential (relative) warm up by Friday.
Winds will pick up as the pressure gradient tightens before, during,
and after the midweek system, but nothing of significance. After
this system moves through we'll see the return of a drier pattern,
but some ensembles depict potential for addition QPF just beyond our
forecast period.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1219 PM CDT Fri Mar 31 2023

Light precipitation will continue on and off today with a few
thunderstorms developing late this afternoon. Widespread precip will
develop later this afternoon and turn to snow from northwest to
southeast this evening. Probabilities for snow rates greater than 1
inch per hour across most of the area from RWF to MSP and to WI is
greater than 70% with sizable probabilities for 2 inch/hr as well.
This heavy snow will reduce visibilities to 1/4 mile or less at these
TAF sites for much of the night. North winds increasing with gusts
of 35 to 40 kts will make for widespread blowing snow as well.
Conditions should improve quickly late tonight and early Saturday
morning as drier air arrives and winds subside.

KMSP...A few showers will remain nearby through the afternoon, with
steadier precip arriving by 01Z. As the main round of precip
develops, could see a few storms - mostly between 23-01Z. Precip will
transition to heavy snow about 02Z, although that may shift by 30
minutes either way. Snow will begin tapering off after 08Z.

/OUTLOOK FOR KMSP/
SAT...VFR. Wind NW 5-10 kts becoming light/variable.
SUN...VFR. Wind S becoming W 10-15 kts.
MON...VFR. Wind NW 5-10 kts.
