.PREV DISCUSSION...
BEGINNING TO SEE A FEW SHOWERS AND THUNDERSTORMS DEVELOP OVER
PORTIONS OF NORTH CENTRAL AND NORTHEASTERN SOUTH DAKOTA THIS
AFTERNOON ALONG AN INSTABILITY AXIS SITUATED OVER THAT AREA...AND
MAY SEE SOME OF THIS ACTIVITY SCRAPE ACROSS OUR NORTHERN LOCALES
INTO THE VERY EARLY EVENING. WITH COLD AIR ALOFT/FREEZING LEVELS
AROUND 6000 FT/WEAK ELEVATED CAPE/MIDLEVEL SHEAR MAY SEE SOME SMALL
HAIL WITH THESE STORMS. OTHERWISE...EXPECTING THIS ACTIVITY TO WANE
AFTER SUNSET. THE UPPER LEVEL LOW CENTERED OVER WESTERN NORTH DAKOTA
LATE THIS AFTERNOON WILL SWING TO THE SOUTH AND EAST
OVERNIGHT...KEEPING A GOOD BIT OF CLOUD COVER IN OUR NORTH...BUT
THINK THAT ANY PRECIPITATION WILL REMAIN TO THE NORTH OF OUR CWA.
EVEN WITH CAA...TEMPERATURES TONIGHT WILL NOT DROP OFF TOO
DRASTICALLY...GENERALLY IN THE LOWER 40S...WITH WINDS STAYING UP IN
RESPONSE TO A TIGHTENING GRADIENT AS SURFACE LOW PRESSURE WINDS UP
ALONG THE U.S./CANADIAN BORDER.  /JM

BRISK WSWLY FLOW SHOULD MIX OUT VERY WELL FOR SAT...WITH WARMEST
TEMPS FOR SERN CWA. WSWLY WINDS SHOULD NOT GET TOO OUT OF CONTROL
WITH LITTLE COLD ADVECTION APPARENT. ALSO APPEARS CAP ABV 600MB
SHOULD PRECLUDE AFTN CONVECTION FOR MOST OF AREA SO WILL LEAVE DRY.
FAIRLY MIXY AND MILD FOR SAT NGT ESP EAST OF I29 WHERE GRADIENT
LINGERS. FOR SUN SHOULD BE COLD ADVECTION ALOFT ASSCD WITH NRN
STREAM SHORT WAVE. PUT IN ISOLD -SHRA ENTIRE AREA IN THE AFTN...
WITH MORE FOCUS TO THE SOUTH...BUT COLDER AIR ALOFT TO THE NORTH.
COOLER SFC RIDGE MOVES ESE OVER CWA SUN NGT AND MAY BE SOME GOOD
RADIATIONAL COOLING. THEN WLY FLOW GRADUALLY BECOMES SLY FM MON THRU
EARLY TUE WITH MODIFYING AIR MASS. BEST WARMING FOR MON AFTN SHOULD
BE ALONG MISSOURI VALLEY WITH WARM ADVECTION...AND FOR TUES WILL BE
SRN AND ERN CWA WITH BEST MIXING ALG AND AHEAD OF CDFNT. 18Z NAM
APPEARS TO HAVE A SLOW AND COLD BIAS DURG THIS PERIOD. PUT IN A SLGT
CHC TSTMS EAST OF I29 TUES AFTN WITH FOCUS AHEAD OF NRN STREAM SHORT
WAVE...BUT ANOTHER WEAK BAROCLINIC ZONE AFFECTS SRN CWA TUES NGT
BEHIND CDFNT. MODELS HAVE TYPICAL CONTINUITY ISSUES WITH SHORT WAVES
IN THE LONG RANGE...BUT IT APPEARS FROM COMPOSITE OF MODELS THAT
THERE IS A CHC OF RAIN MAINLY ALONG AND SOUTH OF I90 FOR THU NGT
INTO FRI MRNG. NO SNOWSTORM LIKE THE 00Z ECMWF HAD...BUT IT SHOULD
BE COOLER THAN 12Z HPC GUID HIGHS FOR WED THRU FRI./ RYRHOLM
