.DISCUSSION...
Issued at 211 PM CDT Wed Apr 2 2025

It has been quite a messy afternoon across southern and western
Minnesota roads as a wintry mix of rain, snow, and sleet impacts
the region. With the low pressure centered overhead, winds have
remained relatively weak. Temperatures remain within a few
degrees of freezing, causing precipitation type issues.
P-types have been going between rain, sleet, and snow depending
on surface temperatures. This mix is creating a messy situation
on the roads. Heavy precipitation rates within the deformation
band mentioned in previous discussions are coming to fruition.
The deformation band set up slightly farther south and east than
expected, leading to an eastward expansion of the Winter
Weather Advisory. This is largely due to the impact we are
seeing the precipitation have on roads in the far western Metro.
Despite relatively mild winds, visibilities across rural
Minnesota have been near or below 1/2 mile for the majority of
the day due to intense snow. It will be awhile before snow
completely stops in central Minnesota, but we have already have
reports of several inches of snow in far west central
Minnesota. Before the rain transitioned to snow, we were also
receiving reports of hail in the areas of heavier precipitation
(with low freezing levels, hail isn`t hard to come by in events
like this).

Precipitation will finally come to an end overnight as the low
tracks toward the Great Lakes and high pressure builds behind
its departure. The pattern aloft features a large trough
centered over the western CONUS and ridging in the east. This
places us in the middle with southwest flow in the upper-levels.
As we head into Friday night, a trough to our north phases with
the aforementioned trough as a developing surface low
progresses northeast. Depending on how these two upper-level
features interact, some models push the northern extent of the
associated deformation zone of this low into the southern half
of our area. The ensembles depict mediocre probabilities
(30-40% chance) for measurable precipitation south of I-90 but
next to zero chance for seeing more than a tenth of an inch
late Friday into Saturday. This is reflected in our grids with a
splattering of 20-30% PoPs and a few hundredths of QPF.
Overall, this shouldn`t be impactful but is the next realistic
shot at any precipitation. Clouds will linger through early
Saturday before clearing out in the afternoon. After this system
moves east, cold air advection will keep high temperatures
below normal for the end of the weekend with highs in the 40s to
lower 50s in far southern Minnesota. This also means highs in
the mid to upper 30s on Monday in west central Minnesota and
western Wisconsin.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 635 PM CDT Wed Apr 2 2025

Lingering snow will continue at KAXN and KSTC tonight. The rest
of the sites will have low clouds. These cloud bases should rise
on Wednesday as drier air moves across the region. Did trend
toward the more optimistic guidance and added VFR conditions
toward the end of the TAF period.

KMSP...
IFR/LIFR ceilings continue this evening, but those should lift
as westerly winds develop overnight and bring drier air across
the region.

/OUTLOOK FOR KMSP/
FRI...VFR. Wind E 5-10kts.
SAT...Chc MVFR cigs early. Wind NW 15G25kts.
SUN...VFR. Wind NW 10-15G25kts.
