DISCUSSION
 
(THIS EVENING THROUGH TUESDAY)  
ISSUED AT 303 PM CDT TUE AUG 9 2022  
 
KEY MESSAGES:  
 
- QUIET, MILD, AND DRY WEATHER THROUGH THIS EVENING AND TOMORROW.  
 
- SEVERAL SMALL CHANCES FOR RAIN NEAR THE END OF THE WEEK THROUGH  
EARLY WEEKEND. ACCUMULATIONS AREN'T LOOKING TO AMOUNT TO MUCH.  
 
A FEW CLOUDS HAVE POPPED UP THIS AFTERNOON, BUT SKY COVER REMAINS  
MINIMAL ACROSS THE NORTH CENTRAL PLAINS. WE REMAIN UNDERNEATH A  
SURFACE RIDGE OF HIGH PRESSURE, WHICH IS THE ATTRIBUTING FACTOR TO  
TODAY AND TOMORROW'S LIGHT WINDS A CLEAR SKIES. WARM AIR ADVECTION  
DUE TO SOUTHERLY SURFACE WINDS ARE STILL FORECAST TO RAISE OUR TEMPS  
INTO THE UPPER 80S IN WESTERN MN AND LOWER 80S IN WEST CENTRAL WI  
TODAY. DEWPOINTS WILL LARGELY REMAIN IN THE 60S, CREATING MILDLY  
MUGGY WEATHER TONIGHT AND WEDNESDAY NIGHT, WITH 70 DEWPOINTS NOT  
UNREASONABLE IN FAR SOUTHERN MN WEDNESDAY AFTERNOON. PATCHY FOG IN  
LOW-LYING AREAS COULD DEVELOP AGAIN TOMORROW MORNING, BUT IMPACTS  
WILL REMAIN MINIMAL.  
 
THE COLD FRONT IS STILL EXPECTED TO SWEEP THROUGH DRY TOMORROW, WITH  
A FEW SMALL CHANCES FOR PRECIPITATION ON THE BACK END ASSOCIATED  
WITH SEVERAL DISTURBANCES. THERE IS A SMALL CHANCE (LESS THAN 20%)  
FOR RAIN THURSDAY MORNING INTO EARLY AFTERNOON IN SOUTHWESTERN  
MINNESOTA. SLIGHTLY HIGHER CHANCES (30-40%) FOR LARGER COVERAGE RAIN  
ON FRIDAY MORNING THROUGH EARLY AFTERNOON. THE SAME PATTERN REPEATS  
SATURDAY MORNING WITH MEDIOCRE POPS (30-40%) IN WEST CENTRAL  
WISCONSIN. GIVEN THE BREVITY OF THESE SHORTWAVES AND A NARROW AREA  
OF BAROCLINICITY, THESE EVENTS COULD BE EASILY MISSED AT ANY GIVEN  
LOCATION. DESPITE ALL OF THESE SLIGHT CHANCES FOR RAIN, LITTLE TO NO  
SIGNIFICANT ACCUMULATION IS EXPECTED IN THE NEXT WEEK, WITH TOTAL QPF  
VALUES OF A QUARTER INCH OR LESS. THE SEVERE POTENTIAL ALSO REMAINS  
NEXT TO ZERO.
