CURRENT SURFACE ANALYSIS SHOWS HIGH PRESSURE CENTERED OVER THE
CENTRAL AND EASTERN DAKOTAS. LOW PRESSURE IS LOCATED ALONG THE
PACIFIC NW COAST...WITH FRONT MOVING QUICKLY EAST ACROSS THE
REGION. UPPER LEVEL ANALYSIS HAS RIDGE AXIS OVER THE HIGH
PLAINS... WITH TROF ALONG THE PACIFIC COAST. SKIES ARE MOSTLY
CLEAR ACROSS THE NORTHERN PLAINS WITH MILD TEMPS CONTINUING. WINDS
HAVE SWITCHED TO THE SOUTH-SOUTHEAST ACROSS MUCH OF THE AREA...A
BIT BREEZY AT TIMES ACROSS WESTERN PORTIONS OF THE CWA.

MILD WEATHER WILL CONTINUE INTO SUNDAY BEFORE THE PACIFIC COLD FRONT
MOVES QUICKLY THROUGH DURING THE LATE MORNING AND AFTERNOON HOURS.
FOR TONIGHT...SKIES WILL STAY MOSTLY CLEAR IN MOST AREAS. SOME LOW
CLOUDS WILL LIKELY DEVELOP ACROSS CENTRAL NEB AND COULD SKIRT SOUTH
CENTRAL SD LATE TONIGHT/EARLY SUNDAY BEFORE SHIFTING EAST OF THE
REGION. WOULD NOT BE SURPRISED TO SEE A FEW PATCHES OF FOG AS WELL
OVER FAR SOUTH CENTRAL SD LATE TONIGHT...BUT NOT SURE IF IT WILL
MOISTEN UP ENOUGH FOR THAT TO HAPPEN.

SUNDAY LOOKS TO BE A MOSTLY SUNNY DAY ACROSS MUCH OF THE AREA...
ESPECIALLY EASTERN PORTIONS OF THE CWA. WILL SEE CLOUDS INCREASE
ACROSS WESTERN AREAS IN THE AFTERNOON WITH A SHOWER OR TWO POSSIBLE
OVER PORTIONS OF NORTHEAST WY BY MID TO LATE AFTERNOON. THE COLD
FRONT WILL MOVE ACROSS NORTHEAST WY AND FAR WESTERN SD DURING THE
LATE MORNING AND ACROSS THE REST OF THE CWA IN THE AFTERNOON. HIGHS
SHOULD RANGE FROM THE 60S OVER NORTHEAST WY TO THE LOWER 80S ACROSS
SOUTH CENTRAL SD. NORTHWESTERLY WINDS WILL BECOME BREEZY BEHIND THE
FRONT. MAIN SHORTWAVE ENERGY WILL LAG BEHIND THE FRONT AND MOVE
ACROSS THE REGION LATE SUNDAY INTO MONDAY MORNING. LATEST MODELS
SHOW THE BEST UPPER LEVEL SUPPORT FOR SHOWERS WILL CROSS WESTERN AND
NORTHERN PORTIONS OF THE CWA SUNDAY NIGHT. WILL KEEP THE BEST
CHANCES FOR SHOWERS FROM NORTHEAST WY THROUGH THE NORTHERN BLACK
HILLS AND INTO NORTHWESTERN SD. THE FORECAST SOUNDINGS SUPPORT THE
POSSIBILITY FOR SNOW SHOWERS LATE SUNDAY NIGHT/EARLY MONDAY OVER
MAINLY THE HIGHER BLACK HILLS. LITTLE OR NO ACCUMULATION IS
EXPECTED.
