DISCUSSION
ISSUED AT 244 PM CDT WED APR 23 2025
TODAY THROUGH SATURDAY...EARLY AFTERNOON SATELLITE IMAGERY
SHOWED MOSTLY SUNNY SKIES ACROSS THE REGION WITH NORTHWEST WINDS
GUSTING TO NEAR 20 MPH AT TIMES. THERE WERE A FEW SCATTERED
CLOUDS ACROSS SOUTHERN MINNESOTA, WITH SOME PRODUCING LIGHT RAIN
SHOWERS OR SPRINKLES. TO THE SOUTH, A STATIONARY BOUNDARY
ACROSS IOWA WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS
LATER TONIGHT. FORECAST SOUNDINGS SHOW A VERY MOIST PROFILE, SO
THE MAIN CONCERN IS THUNDER AS THE RISK FOR SEVERE WEATHER IS
VERY LOW. HIRES MODELS DO SHOW THE POTENTIAL FOR SOME TRAINING,
SO A FEW LOCATIONS COULD PICK UP 1 TO MAYBE 2 INCHES OF RAIN.
THIS SYSTEM WILL EXIT ON FRIDAY AS IT BECOMES MORE ORGANIZED,
AND NORTHEAST WINDS WILL DEVELOP, BRINGING DRIER AND COOLER AIR
INTO THE REGION. THIS WILL SET THE STAGE FOR A GORGEOUS SATURDAY
AS SURFACE HIGH PRESSURE BUILDS ACROSS THE REGION LEADING TO
LIGHT WINDS AND SUNNY SKIES.
SUNDAY THROUGH WEDNESDAY...MAIN CONCERN FOR EARLY NEXT WEEK IS
THE POTENTIAL FOR SEVERE STORMS. THE EXTENDED SEVERE WEATHER
GUIDANCE ALL HIGHLIGHTS THE UPPER MIDWEST FOR SEVERE WEATHER,
AND SPC HAS CONTINUED THE 15% RISK AREA FOR MONDAY. ALL THIS IS
SET UP BY SOUTHWEST FLOW ALOFT THAT WILL BRING A STOUT ELEVATED
MIXED LAYER ACROSS THE REGION, ALONG WITH A SURFACE LOW THAT
WILL ADVECT WARM, MOIST AIR UP FROM THE SOUTH. THE END RESULT IS
A FAVORABLE THERMODYNAMIC AND SHEAR PROFILE FOR SEVERE STORMS.
AWARENESS OF THE GENERAL OUTLOOK IS THE BEST COURSE OF ACTION AT
THIS POINT. AS WE GET CLOSER TO THE EVENT, ONE OF THE FINER
DETAILS TO IRON OUT WILL BE THE POSITION OF THE WARM FRONT, AND
IF THERE IS MORNING CONVECTION.

KMSP...THERE COULD BE A BRIEF PERIOD OF -TSRA AFTER 18Z
