AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
639 AM CDT SUN JUN 1 2014

.SYNOPSIS...
ISSUED AT 315 AM CDT SUN JUN 1 2014

FRONTAL BOUNDARY FROM NRN MN INTO KS WILL MOVE THROUGH IA BY
MONDAY NIGHT. LOW PRESSURE WILL DEVELOP OVER CO TUE AND MOVE EAST
ACROSS NRN MO TUE NIGHT AND WED. COOL PACIFIC HIGH PRESSURE WILL
FOLLOW.

&&

.SHORT TERM /TODAY/...
ISSUED AT 315 AM CDT SUN JUN 1 2014

ONGOING CONVECTION SKIRTING THE NORTHERN EDGES OF THE FORECAST AREA
CURRENTLY AS MOISTURE TRANSPORT FOCUSES INTO BOUNDARY ACROSS SD
AND MN. PWATS WILL CONTINUE TO REMAIN HIGH TODAY WITH MOIST FLOW
FROM THE SOUTH PERSISTING ACROSS THE STATE. WEAK SHORTWAVE
CROSSING THE MISSOURI RVR CURRENTLY WILL PASS THROUGH THE FORECAST
AREA THIS MORNING WITH WEAK FORCING. NAM AND HRRR BOTH DEVELOP SCT
CONVECTION ACROSS THE NORTH AND EAST WITH THE PASSAGE OF THIS
FEATURE AND HAVE CONTINUE THE THREAT IN THESE AREAS THIS MORNING.
THERE APPEARS TO BE A BREAK ACROSS MUCH OF THE AREA EXCEPT THE FAR
NORTH DURING THE AFTERNOON PRIOR TO THE MAIN SHOW STARTING TOWARD
THE END OF THE PERIOD ACROSS NORTHWEST IOWA AND BACK INTO
NEBRASKA. HAVE KEPT THE LIKELY POPS IN THE FAR NORTHWEST DURING
THE LATE AFTERNOON AS CONVECTION IS EXPECTED TO FIRE. THE THREAT
FOR SOME SEVERE WEATHER WILL BE POSSIBLE DURING THIS TIME WITH
LARGE HAIL AND DAMAGING WINDS THE PRIMARY THREAT. HEAVY RAINS ARE
ALSO EXPECTED ALTHOUGH THE MAIN CONCERN WILL BE JUST AFTER THIS
PERIOD INTO THE OVERNIGHT AS LOW LEVEL FLOW FOCUSES INTO WESTERN
IOWA. HAVE GENERALLY GONE WITH TEMPERATURES SIMILAR TO THE PAST
SEVERAL DAYS AS AIRMASS IS ESSENTIALLY THE SAME. THE SCATTERED
CONVECTION OF THE PAST FEW DAYS HAS DONE LITTLE TO KEEP READINGS
FROM THE MID TO UPPER 80S.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
ISSUED AT 315 AM CDT SUN JUN 1 2014

THUNDERSTORMS WILL BE WIDESPREAD TONIGHT WITH THE S/WV AND FRONTAL
SYSTEM MOVING THROUGH THE STATE. EXPECT TO SEE THE PRECIP END
FORM WEST TO EAST MONDAY AS WEAK HIGH PRESSURE BUILDS IN TO THE
STATE.

NEXT WEATHER SYSTEM WILL BE THE WEATHER MAKER OF THE WEEK. LOW
PRESSURE FROM CO WILL EXTEND A WARM FRONT EAST INTO NRN MO. STRONG
H8 SPEED CONVERGENCE IS EXPECTED LATE TUE AND TUE NIGHT AS 60 KT
LLJ IMPINGES ON THE FRONT. DEEP MOISTURE IN PLACE WITH PWAT
VALUES APPROACHING 3 SIGMA OVER CLIMO. SEVERE WEATHER IS A
DEFINITE POSSIBILITY AS DECENT CAPE WILL BE IN PLACE AND
ENVIRONMENT WILL BE STRONGLY SHEARED...UNLIKE THE PAST FEW DAYS.
DECENT DYNAMICS ARE ALSO IN PLACE WITH THE NEGATIVELY TILTED S/WV.
HEAVY RAINFALL WITH POTENTIAL FOR FLASH FLOODING IS ALSO A
SIGNIFICANT THREAT. MODELS DIFFER ON THE PLACEMENT. MOST OVER THE
PAST FEW DAYS HAVE FOCUSED ON THE SOUTH HALF OF IA. FEEL THAT IS
MOSTLY LIKELY GIVEN THE PATTERN AND PAST EXPERIENCE. NAM IS THE
ODD MODEL OUT WITH A FARTHER NORTH POSITION OF THE HEAVY RAINFALL.

COOLER AND DRIER WEATHER IS EXPECTED AFTER THE SYSTEM MOVES TO THE
EAST ON WED. THOUGH THE HIGH IS NOT STRONG ENOUGH TO CUT OFF ALL
CHANCES OF PRECIP...ESPECIALLY DURING THE CLIMO MAX FOR
RAINFALL...THE NEXT PERIOD OF MORE WIDESPREAD THUNDERSTORM
ACTIVITY WILL HOLD OFF UNTIL NEXT WEEKEND.

&&

.AVIATION...01/12Z
ISSUED AT 639 AM CDT SUN JUN 1 2014

WILL SEE MAINLY VFR CONDITIONS THROUGH TODAY WITH UNLIMITED
VISIBILITIES AND CIGS AT OR ABOVE 10KFT. HOWEVER...THERE WILL BE
SOME LOCAL CONVECTION WHICH MAY PRODUCE LOCAL MVFR/IFR CONDITIONS
IN AND NEAR THE STORMS. BY TONIGHT...APPROACH OF SYSTEM WILL LEAD
TO WIDESPREAD THUNDERSTORM ACTIVITY IN CENTRAL IOWA SPREADING FROM
WEST TO EAST OVERNIGHT. PRIOR TO THE ARRIVAL OF THE CONVECTION...
CONDITIONS WILL BE VFR. HOWEVER...A DECREASE TO MVFR OR EVEN IFR
CAN BE EXPECTED WITH THE STORMS AND PRECIPITATION OVERNIGHT. WINDS
WILL BE FROM THE SOUTH TODAY AND FOR MUCH OF THE NIGHT BUT WILL
BEGIN TO BECOME WESTERLY ACROSS WESTERN IOWA LATE TONIGHT BEHIND A
COLD FRONT.

.DMX WATCHES/WARNINGS/ADVISORIES...NONE.
