.SYNOPSIS...
ISSUED AT 319 AM CDT SUN MAR 29 2015

A VIGOUROUS SHORTWAVE TROUGH WAS MOVING THROUGH THE
NORTHERN PLAINS. SHOWERS EXTENDED AS FAR SOUTH AS WESTERN AND
CENTRAL NEBRASKA, ALONG AND AHEAD OF THE LEADING EDGE OF AN
ADVANCING COLD FRONT OVER WESTERN NEBRASKA. FARTHER SOUTH, WESTERN
KANSAS REMAINED BASICALLY IN THE WARM SECTOR VERY EARLY SUNDAY
MORNING, WITH BREEZY SOUTH WINDS AND TEMPERATURES SLOWLY FALLING
THROUGH THE 50S OVERNIGHT.

&&

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 319 AM CDT SUN MAR 29 2015

THE ARW, NMM AND NAM ARE ALL IN FAVOR OF DRIVING THE RAIN SHOWERS
MORE EAST THAN SOUTH, INTO EXTREME NE KS AND KEEPING CENTRAL KANSAS
DRY. THE COLD FRONTAL TIMING SHOULD BE THROUGH DODGE CITY AROUND 9
TO 10 UTC WITH WINDS TURNING NORTH ACROSS THE REST OF SOUTH CENTRAL
KANSAS BEFORE AROUND 8 AM. WINDY CONDITIONS WILL THEN REMAIN  THROUGH
THE AFTERNOON BEFORE WIND RAPIDLY WEAKEN THROUGH SURFACE COOLING IN
THE EARLY EVENING. MODELS AND MOS DO INDICATE A FAIR DEGREE OF
VARIANCE IN HIGHS THIS AFTERNOON BETWEEN UPPER 60S AND LOW 70S IN
THE NORTHERN SECTIONS OF OUR FORECAST AREA (RUSH CENTER - HAYS
REGION) WHILE MORE CONSISTENT WITH LOW 70S ALONG THE OKLAHOMA LINE.
DEW POINTS ARE ALSO QUESTIONABLE AS THE HRRR SPREADS DRIER AIR THAN
THE NAM IN THE EARLY AFTERNOON HOURS.  TEMPERATURES OVERNIGHT
SUNDAY/EARLY MONDAY WILL NOT BE AS MILD FOLLOWING COOLER AND DRIER
AIR MOVING INTO THE REGION. LOW TEMPERATURES ARE EXPECTED TO BE
COOLER BY ABOUT 10 DEGREES IN MOST LOCATIONS.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 1256 AM CDT SUN MAR 29 2015

THE MEDIUM RANGE MODELS SHOW A FAIRLY ACTIVE WESTERLY FLOW PATTERN
OVER NORTH AMERICA THROUGH THE EXTENDED PERIOD. DURING THE EARLY
PART OF THE PERIOD, ON MONDAY THROUGH TUESDAY, AN UPPER LEVEL RIDGE
WILL MOVE OUT OVER THE NORTHERN AND CENTRAL PLAINS. AT THE SAME
TIME, AN UPPER LEVEL TROUGH CURRENTLY OFF THE COAST OF SOUTHERN
CALIFORNIA AND NORTHERN BAJA WILL MOVE INTO THE SOUTHERN PLAINS. THE
00Z GFS IS CONTINUING TO SHOW A TREND OF DEVELOPING SHOWERS AND
THUNDERSTORMS AS FAR NORTH AS SOUTH CENTRAL KANSAS BY LATE TUESDAY
AFTERNOON INTO TUESDAY EVENING.

ANOTHER SHORTWAVE TROUGH IS PROGGED TO MOVE OUT OF THE WESTERN
STATES TOWARD THE CENTRAL PLAINS BY MID WEEK. THE GFS SHOWS A 110
KNOT UPPER LEVEL JET ASSOCIATED WITH THIS WAVE NOSING OUT INTO THE
CENTRAL HIGH PLAINS WEDNESDAY AFTERNOON AND EVENING.  LOW LEVEL
MOISTURE RETURN APPEARS TO BE MOST FAVORABLE INTO CENTRAL AND
EASTERN KANSAS AND COULD RESULT IN ENOUGH INSTABILITY FOR A FEW
STRONG THUNDERSTORMS ALONG A DRYLINE THAT IS PROGGED TO DEVELOP.

A COLD FRONT WILL SWEEP SOUTH ACROSS THE CENTRAL HIGH PLAINS
WEDNESDAY NIGHT WHICH WILL KNOCK TEMPERATURES BACK BY SOME 5-10
DEGREES FOR THURSDAY. THE MAIN UPPER LEVEL SHORTWAVE MOVES OUT OF
THE ROCKIES THURSDAY NIGHT INTO FRIDAY WHICH COULD BRING SOME
SHOWERS TO WEST CENTRAL AND NORTHWEST KANSAS.

ANOTHER RIDGE IS PROGGED TO BUILD INTO THE CENTRAL PLAINS EARLY INTO
THE WEEKEND BUT ANOTHER TROUGH WILL BE MOVING IN ON ITS HEELS LATE
IN THE WEEKEND. THIS COULD BRING ANOTHER ROUND OF SHOWERS AND STORMS
TO WESTERN AND CENTRAL KANSAS BUT DETAILS ON TIMING AND AREAL
COVERAGE ARE STILL FAIRLY UNCERTAIN.

ISSUED AT 319 AM CDT SUN MAR 29 2015

RED FLAG CONDITIONS CANNOT BE COMPLETELY RULED OUT EARLY THIS
