.UPDATE...
NO MAJOR UPDATES MADE TO THE FORECAST THIS MORNING. AREA OF
SHOWERS CONTINUES TO PUSH EASTWARD AND LOOKS TO BE OUT OF THE AREA
SOMETIME AROUND MID AFTERNOON OR SO. SKIES HAVE CLEARED ACROSS THE
WESTERN ZONES...BUT MORE CLOUDS LOOK TO BE MOVING IN FROM THE
NORTHWEST. NO CHANGES MADE TO WINDS OR TEMPERATURES. NEW AVIATION
DISCUSSION BELOW.

.PREV DISCUSSION...
.SHORT TERM...THROUGH SATURDAY

GUIDANCE HAS PEGGED LOCATION OF STRONG BAROCLINIC FORCING ALOFT
FROM KRAP TO KMBG...NORTHEAST TO KJMS. MUCH BRIGHTBANDING WITH SUB
CLOUD EVAPORATION ONGOING...SO QPF SHOULD REMAIN ON THE LOW SIDE.
GUIDANCE WEAKENS THE DEGREE OF FORCING AS IT PROGRESSES EAST
THROUGH THE AM AND INTO THE EARLY AFTERNOON...HOWEVER LACKING A
FEATURE TO DRY US OUT...WITH WEAK/NEUTRAL LIFT...WILL CONTINUE TO
SEE LIGHT SHOWER ACTIVITY THROUGH THE DAY. THE TREND HAS BEEN TO
PUSH QPF WITH FRIDAYS SYSTEM SOUTH...SO HAVE LOWERED
POPS/QPF...AND DRY CONDITIONS REMAIN AS SURFACE RIDGE AXIS NUDGES
INTO THE NORTHEAST FOR REMAINDER OF THE PERIOD. TRENDED MAX
TEMPERATURES DOWN DUE TO CLOUD COVER AND POOR MIXING CONDITIONS
OVER NEXT SEVERAL DAYS...THOSE SAME CONDITIONS RESULTING IN MILD
OVERNIGHT TEMPERATURES.

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY
AGREEMENT BETWEEN NUMERICAL WEATHER PREDICTION MODELS IS IMPROVING WITH
REGARD THE LARGE SCALE PATTERN OVER THE WESTERN AND CENTRAL U.S.
THROUGH THE EXTENDED FORECAST PERIOD. AN INITIAL SHORT-WAVE TROUGH
IS PROGGED TO EJECT NORTHEASTWARD OUT OF A PARENT LONG-WAVE TROUGH
OVER THE WESTERN CONUS SATURDAY EVENING. THE ASSOCIATED SURFACE
LOW/TROUGH WILL TRANSLATE EASTWARD THROUGH NORTHERN SOUTH DAKOTA
SATURDAY NIGHT. MODELS ARE IN VERY GOOD AGREEMENT FOR SUNDAY
PROGGING A TRAILING SW-NE ORIENTED JET STREAK AND ASSOCIATED H5
SHORT-WAVE MOVING THROUGH THE CWA DURING THE DAY SUNDAY. THIS
TROUGH PASSAGE WILL BRING ANOTHER CHANCE FOR AREAS OF LIGHT RAIN.
MODELS FINALLY COMING INTO BETTER AGREEMENT WITH AT LEAST THE
TIMING OF THE EASTWARD TRANSLATION OF THE ABOVE MENTIONED LONG-
WAVE TROUGH/CLOSED LOW AS IT GETS MODIFIED BY THE CENTRAL AND
NORTHERN ROCKIES MONDAY NIGHT AND TUESDAY. ECMWF CLOSES OFF THE
UPPER LOW FARTHER TO THE SOUTHEAST NEAR YANKTON BUT THE SENSIBLE
WEATHER OVER SOUTH DAKOTA IS VERY SIMILAR TO THE GFS SOLUTION.
ADDED HIGHER PRECIP CHANCES FOR MONDAY NIGHT INTO TUESDAY GIVEN
THIS GOOD AGREEMENT BTWN OPERATION MODELS AND GFS ENSEMBLE
MEMBERS. PRECIPITATION AMOUNTS WILL BE THE MAIN CHALLENGE MONDAY
NIGHT THROUGH WEDNESDAY. LATEST INDICATIONS ARE THAT A QUARTER TO
A HALF INCH OF RAINFALL ARE POSSIBLE WITH THIS FAIRLY SLOW MOVING
SYSTEM. ALSO ADDED A SLIGHT CHANCE FOR SNOW ON WEDNESDAY AS A COLD
CANADIAN AIRMASS GET PULLED SOUTHWARD INTO THE NORTHERN PLAINS.

ABOVE NORMAL TEMPERATURES WILL CONTINUE THROUGH TUESDAY WITH
