.DISCUSSION...
Issued at 240 PM CDT Fri Apr 26 2024

Our first round of rain from this morning is exiting eastern
Minnesota and heading into northwestern Wisconsin early this
afternoon. Further south and west, a new line of showers and
thunderstorms is moving across southwestern Minnesota. Some hail has
been reported with these storms across northwest Iowa, but as they
continue into Minnesota, they will outrun the instability to our
south. CAMs show this second line of showers and storms filling in
from far northeastern South Dakota down through central Iowa as they
move northeastward across the MPX area and lose some of their punch.
There is a threat for some hail with any of the stronger storms,
particularly across southern Minnesota, but these storms are not
expected to be severe. This wave will move into central Minnesota
and western Wisconsin by late this afternoon with yet another on its
heels. If we were to see any severe hail, it would be with this
third line of storms as the warm front over Iowa continues to lift
northward. However, confidence is low that this warm front will make
it into Minnesota by this evening, limiting the chances for severe
weather. In any case, rain is still expected area-wide through
tonight with an additional quarter to half inch (with locally higher
amounts) through Saturday morning.

Rain will end by mid morning across much of the area as the surface
low slides overhead. The aforementioned associated warm front will
lead to quite a temperature spread from western Minnesota in the mid
to upper 50s for highs to near 70 in western Wisconsin. Cloud cover
will stick around but winds will let up a bit before we find
ourselves on the backside of this system with another surface
low ejecting out of the Rockies and into the Central Plains on
Sunday morning. This will be another widespread 0.75"-1.5" rain
event through much of the day. Thunderstorm wise, we will again
find ourselves on the wrong side of the warm front with any
severe chances remaining to our south and east.

As we head into the final days of April, we`ll warm up and dry out a
bit. Monday will still be on the cooler side with breezy west winds
and mostly cloudy skies as the low continues on into northern
Minnesota before southerly flow ramps up overnight and into Tuesday,
sending highs back into the upper 60s and low 70s. More showers are
possible Tuesday ahead of a cold front as a quick moving shortwave
moves along the International Border. Shower chances linger through
the middle of the week with continued breezy winds and temperatures
in the 50s and 60s.

Issued at 631 PM CDT Fri Apr 26 2024

Showers and storms over central MN will continue to push north,
giving a brief break in precip early this evening. However, more
convection is expected to develop over IA and southern MN later
this evening as a surface low pushes northeast from eastern NE.
Mainly IFR is expected overnight as cigs drop below 1000 feet
but periods of LIFR are possible with any thunderstorms reducing
visibilities and cigs further. Rain should push off to our north
near or before sunrise Saturday morning with a slow improvement
of cigs afterwards from IFR in the morning to eventually MVFR
by the afternoon. East-southeasterly winds of 17-23 knots will
gust to 25-30 knots this evening but steadily slow across and
turn to northwesterly from west to east overnight into Saturday
afternoon as the low passes.

KMSP...Expecting additional showers and cigs to drop to IFR
this evening. IFR conditions generally expected thru the
overnight but a brief period of MVFR cigs is possible from
07-10z Saturday. MSP should improve to MVFR by early Saturday
afternoon. Southeasterly winds will gust to over 30 knots this
evening, steadily slowing to near 10 knots and turning clockwise
to northerly by Saturday evening.

/OUTLOOK FOR KMSP/
SUN...MVFR/-RA, chance IFR/TS. Wind ENE 15-20G25-30 kts.
MON...MVFR/-SHRA early, then VFR. Wind W 15-20G30 kts.
TUE...Mainly VFR. Chance PM MVFR/-SHRA. Wind SW 10-15G20-25 kts.
