DISCUSSION
ISSUED AT 310 PM CDT MON JUN 8 2026
BROAD WARM AIR ADVECTION TODAY WILL CONTINUE PROVIDE FOR A
SIMILAR ENVIRONMENT TO WHAT WE HAVE SEEN OVER THE PAST 24 HOURS
AS WARM, MOIST AIR MOVES IN LITTLE SHEAR IS PRESENT AND THIS HAS
BEEN AN INHIBITING FACTOR IN ORGANIZED CONVECTION. WE HAVE AND
WILL CONTINUE TO SEE PRECIPITABLE WATER VALUES IN THE 99TH
PERCENTILE. THIS AIR MASS WILL PRESENT THROUGH THE MIDDLE OF THE
WEEK. THE LARGE SCALE PATTERN SEEMS FAIRLY WELL ESTABLISHED FOR
THIS FORECAST WITH ROUGHLY DISTINCT TWO PARTS OF THE WEEK. THE
MID POINT WILL BE WEDNESDAY'S SEVERE STORM CHANCES. BEFORE THIS
WARM AND HUMID WITH DAILY THUNDERSTORM CHANCES. AFTER THIS
COOLER, NEAR TO BELOW NORMAL TEMPERATURES ARE EXPECTED WITH MUCH
LOWER STORM CHANCES OWING TO THE DECREASE IN HEAT THEREFORE
INSTABILITY.
REST OF TODAY THROUGH WEDNESDAY... A BUILDING TROUGH OVER THE
WESTERN CONUS WILL MOVE INTO THE UPPER MIDWEST BY THE MIDDLE OF
THE WEEK. AHEAD OF THIS TROUGH TODAY WE WILL SEE, AS MENTIONED
ABOVE, MORE OF THE SAME SHOWERS AND NON-SEVERE THUNDERSTORMS
WITH HEAVY RAIN AS THE MAIN RISK OWING TO OUR WELL ABOVE NORMAL
PRECIPITABLE WATER VALUES. LOOKING AHEAD TO TOMORROW, ATTENTION
WILL BE MAINLY WELL TO OUR WEST NEAR THE COLD FRONT. IT IS HERE
WHERE CI WILL OCCUR AND THESE STORMS WILL GROW UPSCALE AS THEY
MOVE ACROSS MAINLY ND, BUT ALSO NORTHERN SD. WITH THE UPSCALE
GROWTH THE MAIN RISK ON TUESDAY WOULD BE FOR STRONG WINDS. OVER
THE DAKOTAS THERE IS A SIGNIFICANT RISK, BUT FOR US IT IS MUCH
LESS CERTAIN. IF A MCS CAN DEVELOP A STRONG COLD POOL THE MCS
WILL PERSIST INTO MINNESOTA WITH STRONG WINDS THROUGHOUT. THE
OTHER CONCERN IS HOW FAR SOUTH WILL THIS LINE GET? NORTH DAKOTA
IS WHERE IS LOOKS MOST LIKELY WITH SOME ENSEMBLE MEMBERS GOING
INTO SOUTH DAKOTA. IT WILL BE DEPENDENT ON THE SOUTHERN EXTENT
OF THIS LINE TO SEE IF CENTRAL MINNESOTA SEE IMPACTS FROM THIS
POSSIBLE MCS. THE SAME BOUNDARY FROM TUESDAY WILL BE OVER US ON
WEDNESDAY AND SHOULD FIRE UP ANOTHER ROUND OF CONVECTION
SOMEWHERE BETWEEN EASTERN MINNESOTA AND WESTERN WISCONSIN. HOW
STRONG THESE INITIAL STORMS COULD BE WILL DEPEND ON HOW TUESDAY
PLAYS OUT. IF WE SEE A LARGE MCS MOVE ACROSS MINNESOTA IT WILL
DECREASE SEVERE CHANCES ON WEDNESDAY WITH LESS "FUEL" AVAILABLE
FOR THE NEXT ROUND OF STORMS. IF THE MCS EITHER DOESN'T COME
TOGETHER OR DOESN'T MAKE IT INTO MUCH IF ANY OF MINNESOTA WE
WILL HAVE A MUCH BETTER CHANCE FOR SEVERE STORMS ON WEDNESDAY.
FOR THIS SECOND ROUND WE COULD SEE SUPERCELLS AND ALL MODES OF
SEVERE (WIND, HAIL, AND TORNADO) WOULD BE IN PLAY. THE OTHER
STORY OF THIS PERIOD BEYOND THE STORM CHANCES WILL BE HEAT. THIS
IS TIED DIRECTLY INTO THE CONVECTIVE FORECAST AS THE MORE RAIN,
CLOUDS, AND CONVECTION IN GENERAL WE SEE THE MORE WE WILL TREND
TO THE COOLER SIDE OF THE FORECAST. AT THE MOMENT MUCH OF THE
GLOBAL ENSEMBLE GUIDANCE STILL PUTS BOTH DAYS WITH TEMPERATURES
IN THE LOW TO MID 90S. THERE ARE A FEW OUTLIERS STAYING IN THE
80S TIED TO THAT MORE WIDESPREAD RAIN SOLUTION.
THURSDAY INTO THE WEEKEND... BEHIND THE FRONTAL PASSAGE COLDER
AND DRIER AIR WILL ARRIVE ON THURSDAY. THE UPPER WAVE WILL BE
OVERHEAD ON THURSDAY SO STILL SOME RAIN CHANCES, BUT LESS THAN
THE SEVERE RISKS OF TUESDAY AND WEDNESDAY. COOLER AIR WILL
CONTINUE TO ADVECT IN THROUGH THE WEEKEND WITH HIGHS GENERALLY
IN THE LOWER TO MID 70S, WHICH IS ACTUALLY BELOW NORMAL NOW AS
NORMALS ARE PUSHING INTO THE UPPER 70S BY THIS POINT IN JUNE.
AFTER A BUSY EARLY AND MID WEEK, THE LATE WEEK LOOKS TO BE A
NICE BREAK FROM MORE ACTIVE WEATHER.
AVIATION /00Z TAFS THROUGH 06Z WEDNESDAY/
ISSUED AT 712 PM CDT MON JUN 8 2026
VFR CONDITIONS TO START AT ALL SITES WITH PRECIPITATION NO
LONGER EXPECTED IN A BROAD SENSE. CANNOT RULE OUT ISOLATED
CONVECTION IN WESTERN MN THRU THIS EVENING AHEAD OF THE COLD
FRONT, BUT THE LOSS OF DAYTIME HEATING SHOULD QUICKLY ALLOW ANY
REMAINING DIURNAL SHOWERS/THUNDERSTORMS TO COME TO AN END. WILL
MONITOR RADAR TRENDS AND ISSUE AMDS AS NEEDED. GOING INTO THE
OVERNIGHT HOURS, WINDS WILL DROP TO NEAR CALM. PLENTIFUL
BOUNDARY LEVEL MOISTURE TRAPPED UNDER THE NIGHTLY INVERSION PLUS
PARTIALLY CLEARING SKIES SHOULD ALLOW FOR SUFFICIENT RADIATIONAL
COOLING CONDITIONS TO MAKE FOR FOG FORMATION, PARTICULARLY IN
EASTERN MN THRU WESTERN WI OVERNIGHT INTO DAYBREAK. HAVE
ACCOUNTED FOR THIS MAINLY VIA TEMPO GROUPS, WITH CONDITIONS
GENERALLY INTO MVFR RANGE WITH IFR-OR-WORSE POSSIBLE, MOST
LIKELY AT RNH-EAU. CONDITIONS WILL IMPROVE TO VFR AFTER SUNRISE
AND REMAIN THERE THROUGH THE DAY TOMORROW WITH NO PRECIPITATION
EXPECTED PRIOR TO 00Z. WINDS WILL GENERALLY BE UNDER 10KTS
TOMORROW, EXCEPT FOR FAR WESTERN SITES (AXN-RWF) WHICH MAY SEE
MORE BREEZY/GUSTY CONDITIONS.
KMSP...VFR CONDITIONS ARE EXPECTED FOR MOST OF THIS CYCLE ALONG
WITH PRECIPITATION-FREE CONDITIONS. PRECIPITATION CHANCES
INCREASE LATE TUESDAY EVENING, SO THERE IS TOO MUCH UNCERTAINTY
TO INCLUDE ITS MENTION IN THIS 09/00Z CYCLE OUT TO 30 HOURS BUT
STARTING WITH THE NEXT SET OF TAFS, SHOWERS/THUNDERSTORMS ARE
LOOKING LIKELY FOR TUESDAY NIGHT INTO WEDNESDAY MORNING SO THE
ADDITION OF PRECIP IN THE NEXT TAF IS LOOKING PROBABLE. AS FOR
FLIGHT CONDITIONS, THE ONLY WRINKLE IS FOG IN THE PRE-DAWN
THROUGH SUNRISE HOURS. HAVE ONLY BROUGHT CONDITIONS DOWN TO MVFR
AT THIS POINT, AS FOG TYPICALLY HALTS IN THE MVFR RANGE WHILE
EVEN THE SATELLITE AIRPORTS DROP TO IFR-OR-WORSE CONDITIONS. IF
WINDS DROP OFF TO CALM, IFR-OR-WORSE CONDITIONS ARE CERTAINLY
POSSIBLE.
