.DISCUSSION...
Issued at 315 PM CDT Wed May 1 2024

Short Term:

Scattered clouds through this afternoon will become more
widespread across our area as well as increase in coverage as a
shortwave trough drops out of the Canadian Prairies and into the
Northern Plains. This will be the focus of any precipitation
that we see in the coming 24 hours. Initially a warm front will
move through the area this afternoon bringing showers and
drizzle with it as it passes through the area. It appears that
Central Minnesota may not see much precipitation with this
initial round due to a fair bit of dry air closer to the
surface. Conversely, areas east of I-35, and near the border
with Canada have better rain chances due to marginally more
moist lower levels. By late tonight most of the precipitation
from the front will have moved off to the east with scattered
showers near the eastern edges of our CWA. Around daybreak
Tuesday is when our precipitation chances return as the
shortwave finally moves overhead and produces more chances for
rain and maybe some snowflakes on the backend. As the cold front
associated with the shortwave moves North to South early
tomorrow, we will see another bout of precipitation. Initially
the precipitation will remain all rain but during early morning
as strong cold air occurs, we will see temperatures drop into
the mid to upper 30s. With these temperatures we could see a few
flakes in the colder pockets and where we have stronger
convection where evaporative cooling can enhance the cooling
effect. As it stands right now, the Minnesota Arrowhead and
South Shore areas look to have the best chance (50-60%) of
seeing some snowflakes mix-in heading into the afternoon. By
late afternoon, most of the precipitation will have moved out of
our CWA with much cooler temperatures present with highs in the
upper 30s (closer to the lake) to mid 40s (Inland).

Extended Range:

Wednesday will be on the cooler side with highs remaining in the
40s and 50s with persistent NW wind making it feel on the
chillier side. Very dry soundings indicate the return of near-
critical fire weather conditions across far northern Minnesota
and northwestern Wisconsin during the day. This cold, dry spell
will be brief before well see a quick warmup into the upper
50s/lower 60s on Thursday as winds return to a more southerly
component, which will advect some moisture for slightly less dry
conditions.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 100 AM CDT Thu May 2 2024

An approaching low pressure system will cause the current VFR
conditions to deteriorate after 10z this morning. Ahead of the
rainfall, fog may affect KDLH, KHIB and KINL, and have included
some MVFR visibilities for a few hours before the rain moves in.
The rain will cause ceilings and visibilities to be reduced to
MVFR initially for most locations, with further deterioration
expected later in the day to IFR, mainly for ceilings. KDLH to
also get IFR visibilities and LIFR ceilings. The lowest
conditions are expected in the 00z - 06z time frame. Improvement
is expected after 06z as the rain lifts out of the area to the
north.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 100 AM CDT Thu May 2 2024

Westerly winds continue to weaken this evening, with calmer
conditions expected overnight. Northeast winds strengthen
through the day Thursday, with waves building in response. Peak
gusts up to 25 knots and waves up to 5 to 7 feet could be
possible tomorrow afternoon and evening at the head of the lake.
Elsewhere, expect winds and waves slightly less than that, but
still breezy with gusts largely over 20 knots. Another round of
Small Craft Advisories will likely be needed. Into Friday,
expect winds to turn southwesterly and become very strong
through the day Friday.
