.SHORT TERM.../TONIGHT /...
ISSUED AT 351 PM CDT SAT APR 13 2013

HIGH PRESSURE RIDGE FROM ERN ND INTO WRN IL WILL MOVE TO THE EAST
TONIGHT WITH WINDS SWINGING AROUND TO THE SOUTHEAST AND INCREASING
TONIGHT.  MOISTURE TRANSPORT WILL BE GOOD TONIGHT WITH H8 JET OF 65
KTS SETTING UP INTO THE STATE BY MIDNIGHT OR SO.  WAA CLOUDS ARE
ALREADY BECOMING WELL ESTABLISHED FROM ERN NEBRASKA INTO NRN MO.
EXPECT TO SEE SOME ISOLATED SHOWERS AND THUNDERSTORMS DEVELOP OVER
THE SOUTHWEST AND CENTRAL PART OF THE STATE...BECOMING WIDESPREAD
OVER THE CWA OVERNIGHT.  BEST THETA-E PUSH COMES IN THE 05-09Z
TIMEFRAME AND MAXED OUT THE POPS AROUND THAT TIME.  QPF MAY BE A BIT
LIMITED AS IT WILL TAKE A WHILE FOR DEEPER MOISTURE TO RETURN.  IT
WILL ALSO BE A RACE BETWEEN THE WAA DEVELOPMENT AND THE ADVANCING
WEAK EML HEADING INTO THE STATE LATER TONIGHT.  TEMPERATURES ARE NOT
LIKELY TO DROP A GREAT DEAL TONIGHT WITH THE INCREASING CLOUDS AND
WIND.  OVERALL...WENT ABOUT 5 TO 10 BELOW CURRENT TEMPS.

.LONG TERM.../SUNDAY THROUGH SATURDAY/...
ISSUED AT 351 PM CDT SAT APR 13 2013

TWO MAIN SYSTEMS OF NOTE THROUGHOUT THE EXTENDED RANGE...WITH THE
FIRST SYSTEM IMPACTING THE AREA TONIGHT INTO SUNDAY NIGHT. PRECIP
EXPECTED TO BE ONGOING SUNDAY MORNING...AS MAIN SFC LOW TRACKS
EASTWARD FROM WYOMING THROUGH SOUTH DAKOTA. ASSOCIATED WARM FRONT
TO LIFT NORTHWARD THROUGH THE STATE...WITH OVERRUNNING SCENARIO
LEADING TO LARGE AREA OF PRECIP ACROSS MUCH OF THE
NORTHERN/EASTERN TWO THIRDS OF THE CWA SUNDAY MORNING. ASSOCIATED
COLD FRONT TO SWING THROUGH THE STATE SUNDAY AFTERNOON INTO SUNDAY
EVENING...WITH SOME THUNDERSTORMS EXPECTED ALONG AND AHEAD OF THE
FRONTAL BOUNDARY. SOME POST-FRONTAL SHOWERS EXPECTED AS WELL. DRY
SLOT TO ROTATE THROUGH CWA LATE SUNDAY EVENING INTO SUNDAY NIGHT
WITH ANY PRECIP CHANCES CONFINED TO THE FAR SOUTHEASTERN CWA WHERE
FRONTAL BOUNDARY SLOWS DOWN PROGRESSION. SYSTEM THEN PRETTY MUCH
EXITS THE AREA...BUT DO BEGIN TO SEE SOME RETURN FLOW ALOFT INTO
MONDAY NIGHT TUESDAY NIGHT. NEARLY STATIONARY BAROCLINIC ZONE SITUATED
NEAR THE IA/MO BORDER AND THETA-E ADVECTION IN SOUTHERLY FLOW
ALOFT MAY LEAD TO SOME LINGERING LIGHT SHOWERS ACROSS THE EXTREME
SOUTH/SOUTHEASTERN CWA.

OTHERWISE MAIN FOCUS THEN SHIFTS TO THE DEEP UPPER LEVEL TROUGH
DIGGING INTO THE WESTERN/CENTRAL US TOWARD MID/LATE WEEK. THIS
SYSTEM WILL SLOWLY SLIDE EASTWARD THROUGH THE CENTRAL US THROUGH
THE LATTER PORTION OF THE WEEK...WITH SEVERAL PRECIPITATION
CHANCES EXPECTED WITH THIS SYSTEM WEDNESDAY INTO FRIDAY. INITIALLY
CWA IN THE WAA REGION...WITH BAROCLINIC ZONE SLICING THE CWA IN
HALF AND MOISTURE STREAMING NORTHWARD OFF THE GULF. THIS SHOULD
RESULT IN DECENT PRECIPITATION CHANCES ACROSS THE CWA WEDNESDAY
INTO WEDNESDAY NIGHT...WITH COLD FRONT MAKING ITS WAY ACROSS THE
CWA LATE WEDNESDAY NIGHT. THEREFORE COULD SEE SOME PRECIP TOWARD
THE NORTHWESTERN/NORTH CENTRAL CWA MIXING WITH SNOW OR CHANGING
OVER TO ALL SNOW. ALSO COULD SEE SOME THUNDER WITH THE WARM SIDE
OF THIS SYSTEM WEDNESDAY. UPPER LEVEL TROUGH DROPS THROUGH THE CWA
LATE THURSDAY NIGHT INTO FRIDAY...WHICH COULD BRING SOME LINGERING
LIGHT RAIN/SNOW CHANCES. WAA IS THEN EXPECTED TO PUSH INTO THE CWA
ALOFT FOR SATURDAY WITH NORTHWEST FLOW PATTERN ALOFT. THIS COULD
RESULT IN ANOTHER CHANCE FOR SOME LIGHT RAIN ACROSS THE
STATE...BUT WILL BE DEPENDENT ON MOISTURE RETURN. OVERALL
TEMPERATURES THROUGHOUT THE PERIOD...LOOKING TO REMAIN COOLER WITH
THE EXCEPTION OF SUNDAY WHICH COULD BE FAIRLY MILD ACROSS THE
SOUTHERN HALF OF THE CWA IN THE WARM SECTOR.
