.DISCUSSION...
Issued at 325 PM CST Fri Mar 6 2026

There are some impressive temperature gradients across the central
CONUS today associated with the low over central KS. The warm front
with the low extends up to about the I-80 corridor in Iowa. To the
north, there`s a northern stream cold front moving across western
MN. We`re seeing some 70s all the way up into southern Iowa within
the warm sector, while behind the cold front, temperatures in the
teens and 20s in the Dakotas have sent temperatures in western MN
down into the upper 20s to lower 30s. Through tonight, the surface
low will track across central Iowa and across the southeast corner
of MN on its way to northeast WI Saturday morning. With this track,
the MPX area will remain within the cold sector of this system.
Therefore when it comes to hazardous weather, we won`t have to worry
about the severe side of things, instead, we can place our focus on
the cold side.

For the rest of tonight, there`s a lot of moving parts. For
temperatures, the CAA moving into western MN is shallow and we`re
developing fairly classic freezing rain soundings where temperatures
have fallen below freezing at the surface. These freezing rain
profiles will remain in place through roughly 3z (10pm), with the
warm nose finally cooling down after that, with a wintry p-type
changing from freezing rain over to snow. The big question with this
environment is when does the precipitation start falling. The
problem we have now for precipitation is we have very dry mid/upper
level air sitting above our stratus, but as the surface low moves
toward central Iowa this evening, our vertical moisture profile will
start to fill in, with a pretty rapid expansion in precip expected
across the area between 5pm and 7pm. It continues to look like we`ll
have a band of freezing rain out in western MN that will be able to
pickup upwards of 0.2" inches of ice accumulation from roughly
Redwood Falls back to the SoDak border. Though this could move up if
freezing rain starts earlier, or drop if it starts later. Overnight,
a southwest to northeast oriented deformation band of precip will
slowly move across the area from west to east, with early risers
Saturday morning in the Twin Cities likely getting treated to some
falling snow. Saturday will see quite the spread in temperatures
across the area, with clouds making it a struggle for eastern MN and
western WI to get out of the 30s, while sun in western MN will
likely allow highs in west central MN to reach the low to mid 50s.

Sunday will see our warmest push of air during this stretch, with
highs in the 60s expected pretty much area wide. The next front will
push through the area on Monday, how quickly it does so will
determine how warm we get on Monday, though forecast highs for
Monday have trended down some. For the rest of the week, we`ll have
a strong jet overhead, with a strong thermal gradient across the
northern US. With this jet overhead, we`ll see numerous waves sneak
across the northern CONUS. The first comes Tuesday, which is
trending toward central/northern MN, with another for the end of the
week. Precipitation for the most part will be on the cool side of
the thermal gradient, which means where precip falls, it will most
likely fall as snow. As for temperatures next week, we have seen the
EPS slowly modify on the cold, with highs expected to be near
normal, with a warmer day possible Thursday depending on which side
of the Thursday night wave we end up on. As for the cold, that has
been pushed out into next weekend, with a proper spring warmup
possibly lurking for the last week of March.

.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1103 PM CST Fri Mar 6 2026

Multiple p-types ongoing at initialization time across central-
southern MN, including -SN over far western, -FZRA over central
MN and -RA over eastern MN into western WI. The changeover will
slowly shift eastward through time during the early morning
hours, with the duration of any icy/frozen precipitation
dwindling, approaching a more rain-to-snow changeover without
any icy precip. Such a scenario is likely for eastern MN into
western WI but west of the Twin Cities metro, there is generally
a 1-2hr duration of having icy precip for STC-RWF-MKT. Still
have a mention of FZRA at MSP but that is only in a small
temporary window between roughly 08z-10z while -SN also mixes
in. By daybreak, the only remaining p-types for any given site
will be -SN that what lingers beyond sunrise will diminish
entirely prior to noon. Mainly IFR ceilings will prevail through
daybreak, followed by fairly quick clearing for the afternoon
hours through tonight. Breezy NW winds will continue for much of
the day, then back to SW this evening into tonight. By late
Saturday night, strong low level jetting aloft will very likely
create nocturnal LLWS conditions.

KMSP...IFR ceilings to persist through the rest of the overnight
hours, with -RA at the start of this TAF set. There will be a
1-2hr period where FZRA is possible, particularly between
08z-10z, as the temperatures look to remain warm enough to
support liquid rather than icy precip until sufficient cooling
from the upper layers of the atmosphere down to the ground
support light snow. The p-type looks to change to all snow prior
to sunrise, with wet light snow continuing through the morning
push. Precip looks to end shortly after sunrise with clearing
occurring early-mid afternoon. Strong nocturnal jetting aloft
will likely create LLWS conditions from late Saturday evening
onward.

/OUTLOOK FOR KMSP/
MON...VFR. Wind NW 10-15 kts.
TUE...MVFR likely. Chance IFR/-RASN. Wind NE 10-15 kts.
WED...Chc MVFR/-SN early. VFR late. Wind NW 10-15 kts.
