All is quiet here in the very near term now that 1 of 2 shortwaves 
has cleared MN/WI late last night. Temperature observations ranging 
in the low to mid 50s broken mid-level stratus. Clear skies span 
over southwestern MN for now. On radar, a few bands of rainfall 
currently border central MN and western WI to the north extending 
from Lake Superior down over to the central James River Valley in 
the Dakotas. These bands are associated with shortwave number 2 and 
are expect to track across much of the area today this morning. By 
this afternoon, the shortwave arrives over southwestern 
Wisconsin. By that time, redevelopment of showers and 
thunderstorms mainly east of the I-35 corridor this afternoon be
possible as seen in the latest CAM guidance. There was a little
less confidence in the western extent of potential 
redevelopment west of I-35, therefore included 
isolated/scattered verbiage in today's forecast given the 
current environment. Storm intensity today is not expected to 
be strong or severe based off of forecast soundings however a 
few better organized storms may produce small hail and gusty 
winds. Temperatures will range in the low to mid 60s with mostly
cloudy skies gradually clearing from west in the afternoon and 
east by this evening. 

Wednesday through most of Thursday consists of upper-level ridging 
over the intermountain west amplifying as it makes its way eastward 
towards the northern plains. At the surface, high pressure will
be the dominant feature allowing for mostly clear to partly 
cloudy skies, light winds. Temps in the creeping their way up 
gradually through the 70s and lows in the mid 40s and 50s.

Thursday night into the weekend. Ridging will depart to our east as 
a upper-level troughing elongates. Chances for showers and 
thunderstorms look to be on and off all weekend considering the 
broad distribution of vorticity across Minnesota and Wisconsin
during that time. Current QPF forecasts for Sunday night 
Monday, could potentially be the better rainmaker of the period 
with half to three quarters of an inch possible. Early into next
week, general consensus showing agreement on broad scale 
ridging across the western CONUS which may aid in warmer temps 
here as well as less active weather pattern.


Issued at 554 AM CDT Tue May 28 2024

Scattered showers will continue pressing E-SE across all of
central-southern MN into western WI through late morning,
briefly and intermittently moving across the terminals. Mainly
VFR conditions, though short durations of MVFR conditions may
occur. Shower will be more prolonged east of I-35, thus having
more impacts at the WI terminals. Cannot rule out CB/TS should
storms grow tall enough but chances are still too low to 
include. Showers will dissipate and shift off to the east during
the afternoon hours, allowing VFR conditions to develop late 
this afternoon through tonight. Winds will remain mainly NW, 
with some occasional gustiness this afternoon.

KMSP...Have kept the 12z-16z timeframe as the best window for 
MSP to see showers, but additional development this afternoon 
could push that timing out to near 18-20z. Not looking for much 
in the way of QPF, only a few hundredths up to a tenth of an 
inch, thus heavy showers are not expected. Same with CB/TS, 
chances are too low to include at this point.

THU...VFR. Wind SE 10-15 kts.
FRI...Mainly VFR. Chance -TSRA/MVFR. Wind S 10-15 kts.
SAT...Mainly VFR. Chance -TSRA/MVFR. Wind SW 10-15 kts.
