Key Messages...
- Freezing rain and scattered storms tonight
- Rain transitioning to snow Wednesday night and continuing into
Thursday
At 2 PM, a strengthening low pressure system was located over
western Kansas. Under mainly cloudy skies, temperatures ranged
from the lower 30s to lower 40s.
For late this afternoon, the models continue to show that some
isolated to scattered showers will develop across the area as the
850 mb moisture transport gradually increases across the area.
With very dry air (dew points in the single digits and teens),
some of the rain associated with these showers may end up being
mainly virga.
For tonight and Wednesday morning:
The moisture transport will increase across the area as the low
pressure system over Kansas approaches and moves through the
region. Precipitable water values increase into the 0.75 to 1 inch
range north of Interstate 94 and and 1 to 1.25 inches across the
remainder of the area. Soundings continue to show that the
temperatures aloft will warm into 5 to 10C range overnight, so any
freezing rain concerns will depend heavily on what happens in the
boundary layer with the temperatures and dew points. Like the
past couple of days, areas south of Interstate 94 will likely see
just rain tonight. Meanwhile, areas north of there will see
freezing rain. The greatest ice accumulations (0.1 to 0.2 inches)
will be found along and north of Wisconsin Highway 29. Since the
NBM, NBM experimental, and soundings were all suggesting that the
freezing rain would continue into Wednesday morning, the Winter
Weather Advisory was extended to 9 AM.
In addition to the freezing rain tonight, the most unstable CAPES
climb anywhere from 500 J/kg (GFS) to 1500 J/kg (RAP). This will
result in some thunderstorms tonight. With the 1-7 km shear only
up to 30 knots, not expecting any severe weather. However, cannot
rule out some small hail in southeast Minnesota and northeast
Iowa.
Wednesday night - Thursday:
The rain will transition to snow on Wednesday night and then
linger into Thursday. By this time occurs, the precipitable water
values will be on the decrease. In addition, the models are
showing that the deformation band of snow will be moving faster
out of the area. As a result, the snow amounts dropped more into
the 1 to 3 inch range along and north of Interstate 90 and and up
to an inch elsewhere. With this said, there is still uncertainty
on how much snow will fall during this time period.
Thursday Night through Friday:
A break in the precipitation is expected Thursday night through
Friday. Highs Friday will be in the 40s with mostly sunny skies and
light winds.
Friday Night through Tuesday:
A second round of wintry mix precipitation makes it way to the area
Friday night. The area will see the effects of two different low
pressure systems Friday night and Saturday: one moving in from the
southwest that should pass to the south of the CWA, and another
moving eastward across Canada that will stay to the north of the
CWA. We will see rain, possibly mixed with light snow, Friday night
through Saturday, which will be dependent on local temperatures
aloft and at the surface. Snow chances will be greater in northern
parts of the area due to cooler surface temperatures. 850 mb
moisture increases throughout the weekend as saturated air moves in
from the southwest. On Saturday, PWATs range from 0.2-0.5 inches,
which is around the 75th percentile for this time of year.
Precipitation will begin as rain then as temperatures cool
overnight, light snow mixed in will also be possible. Precipitation,
whether rain or snow, should remain light, with flurries or
sprinkles also possible. On Saturday, temperatures will reach the
high 40s or low 50s, so the best chances for some light snow are
late Friday night/early Saturday morning when temperatures are cool
enough to support snow. Models suggest 0 to a trace or few
tenths of snow Saturday. Overall though, light rain is most likely.
And yet another low pressure system moves in early next week,
bringing mostly rain with an off-and-on chance for snow to mix in.
Monday PWATS range from 0.5-0.8 inches, which is around the 90th
percentile for this time of year. Precip looks to begin as rain with
possibly some snow mixed in Sunday night before transitioning to
rain Monday morning, then rain/snow again by Monday evening.
However, there are differing solutions between the EC and GFS in
exactly where this low pressure system will end up, which would
affect how much precipitation the area actually gets. Some models
suggest a convective environment for this event, though MUCAPE stays
to the south of the CWA, keeping possible convection out of the
area. Similar to the Saturday event, temperatures will be well above
freezing in the 40s and 50s, so rain is the main player, with light
snow possible in the cooler overnight and early morning hours.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1231 PM CDT Tue Mar 29 2022
A few showers will develop after 29.21z and then become more
widespread tonight as the 850 mb moisture transport increases
across the area. With most unstable CAPES of 500 to 1500 J/kg some
elevated thunderstorms will develop overnight. Timing was still a
bit too uncertain to add them to the TAFs at this time. These
showers will then continue into Wednesday.
In addition, ceilings will gradually lower to MVFR, between 30.03z
and 30.06z and then become IFR around 30.11z. Visibilities will be
generally MVFR after 30.05z.
Some low level wind shear will be possible at KLSE from 30.05z to
30.11z.

1 wildfire. Local standard time, as filed.
Smoke from a small wildfire in the median of Interstate 94 near Northfield contributed to a two vehicle crash. The smoke caused low visibilities to occur in the southbound lanes of the Interstate where the crash occurred. No injuries occurred as a result of the crash.
