AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1200 AM CDT SUN MAY 26 2013

.SHORT TERM.../TONIGHT /...
ISSUED AT 314 PM CDT SAT MAY 25 2013

THE PRECIPITATION HAD ENDED OVER CENTRAL IOWA BY MID AFTERNOON. AN
AREA OF SUBSIDENCE WEST OF A MESOSCALE CONVECTIVE VORT MAX WHICH IS
EXITING THE REGION SHOULD HELP KEEP IT DRY OVER CENTRAL IOWA INTO
THIS EVENING. THE WARM FRONT WAS WELL DEFINED THIS AFTERNOON FROM
FAR NORTHERN NEBRASKA SOUTHEAST ALONG THE MISSOURI RIVER INTO
NORTHERN MISSOURI. EXPECT ANOTHER MCS TO DEVELOP THIS EVENING AND
THEN MOVE INTO CENTRAL IOWA TONIGHT. EXACT EVALUATION OF THE SYSTEM
IS UNCERTAIN...BUT CONFIDENCE OF IT OCCURRING IS HIGH.  AS FOR THE
FORECAST...WENT WITH HIGH POPS TONIGHT AND A SMALL DIURNAL
TEMPERATURE RANGE. PRIMARY THREAT WILL BE HEAVY RAIN WITH THE MCS.
CONVECTION SHOULD BE ELEVATED AND SEVERE PARAMETERS ARE NOT
FAVORABLE.

.LONG TERM.../SUNDAY THROUGH SATURDAY/...
ISSUED AT 314 PM CDT SAT MAY 25 2013
ACTIVE WEATHER PATTERN WILL CONTINUE OVER THE NEXT SEVERAL DAYS
AS UPPER LEVEL RIDGE REMAINS IN PLACE ACROSS THE CENTRAL PORTION
OF THE COUNTRY ALLOWING FOR SOUTHWEST FLOW TO DOMINATE THE WEATHER
PATTERN. LEANED TOWARD A BLEND...AS MODELS ARE AT LEAST AGREEING
ON OVERNIGHT/EARLY MORNING CONVECTION DURING THE NEXT SEVERAL
NIGHTS...BUT DISAGREE ON LOCATION OF HEAVIEST RAIN.

.SUNDAY THROUGH TUESDAY...ONGOING MCS EXPECTED TO DEVELOP TONIGHT
WILL PUSH INTO NORTHEAST IOWA SUNDAY MORNING.  HAVE CONFINED HIGHEST
POPS THROUGH 18Z SUNDAY IN THE NORTHERN AND EASTERN SECTIONS OF THE
FORECAST AREA. MOISTURE TRANSPORT VECTORS AND THETA-E ADVECTION
CONTINUE SUNDAY MORNING BEFORE DIMINISHING BY THE AFTERNOON HOURS.
CUT BACK ON POPS B/T 18Z SUNDAY THROUGH 00Z MONDAY WITH A BRIEF
PERIOD OF SUBSIDENCE SETTLING IN OVER CENTRAL IOWA SUNDAY AFTERNOON.
ANOTHER SHORTWAVE AND 500 MB VORT MAX...COMBINED WITH LLJ AND
MOISTURE TRANSPORT INCREASING SUNDAY EVENING INTO MONDAY
MORNING...KEPT WITH HIGH POPS THROUGH 18Z MONDAY. WARM LAYER CLOUD
DEPTHS REACH 12000 FEET BY 12Z SUNDAY AND AGAIN BY SUNDAY NIGHT INTO
MONDAY. THIS...COMBINE WITH PRECIPITABLE WATER VALUES RANGING AROUND
1.50 INCHES WILL LEAD TO SOME EFFICIENT RAIN PRODUCERS SUNDAY
MORNING AND LATE SUNDAY NIGHT INTO MONDAY. ANOTHER ROUND OF
EFFICIENT RAIN PRODUCERS SETS UP MONDAY NIGHT INTO TUESDAY WITH A
VERY SIMILAR PATTERN AS TONIGHT AND SUNDAY NIGHT. CUT BACK ON POPS
TUESDAY DURING THE DAY AS SHORTWAVE IS A BIT QUICK TO MOVE NORTHEAST
PAST 12Z TUESDAY.

.WEDNESDAY THROUGH SATURDAY...GFS AND ECMWF ARE COMING TOGETHER WITH
MUCH STRONGER VORT MAX AND 500MB SHORTWAVE TO PUSH ACROSS THE REGION
WEDNESDAY NIGHT INTO THURSDAY. THE 00Z ECMWF IS SLIGHTLY SLOWER THAN
THE 12Z GFS...BUT CONCERNED ABOUT PRECIP AMOUNTS ON TOP OF
ANTICIPATED QPF OVER THE NEXT FEW NIGHTS. THE VERY ACTIVE WEATHER
PATTERN CONTINUES WITH THE GFS/ECMWF BOTH KEEPING THE FORECAST AREA
UNDER SOUTHWEST FLOW AND A SERIES OF SHORTWAVES TO AFFECT IOWA
THURSDAY NIGHT INTO FRIDAY...AND AGAIN FRIDAY NIGHT INTO SATURDAY.
HYDRO ISSUES WILL REMAIN A CONCERN IN THE EXTENDED PERIOD.

&&

.AVIATION...26/06Z
ISSUED AT 1159 PM CDT SAT MAY 25 2013

AN AREA OF THUNDERSTORMS ACROSS CENTRAL IOWA WILL CONTINUE TO
BECOME MORE FOCUSED FARTHER NORTH OVERNIGHT AND GENERALLY IMPACT
THE NORTHERN SITES. DRIER AIR ADVECTING IN FROM GREAT LAKES HIGH
PRESSURE HAS HELPED CIGS INCREASE TO VFR OVER EASTERN IOWA AND
INTO THE EASTERN SITES. WHILE SOME IFR CONDITIONS ARE POSSIBLE YET
THROUGH THE PERIOD...THE DRIER AIR SHOULD TREND CIGS TO MVFR AND
VFR. PRECIPITATION WILL MAINLY BE FOCUSED THROUGH MID SUNDAY
MORNING THEN AGAIN SUNDAY EVENING.

&&

.HYDROLOGY...
ISSUED AT 314 PM CDT SAT MAY 25 2013

THIS MORNINGS RAINFALL WAS SIGNIFICANT IN SPOTS ACROSS CENTRAL IOWA
WITH AN OVER 5 INCH REPORT IN MARSHALL COUNTY. HEAVY RAIN FORECAST
TOOLS SUGGEST THAT THE STORMS ASSOCIATED WITH TONIGHT/S MCS SHOULD
BE VERY EFFICIENT RAINFALL PRODUCERS. BOTH THE GFS/NAM SHOWS A DEEP
WARM CLOUD LAYER...HIGH PRECIPITABLE WATER AND GOOD MOISTURE
TRANSPORT OVER THE WARM FRONT. ALTHOUGH THE 850-700 MB THETA E
ADVECTION IS NOT AS STRONG AS THIS MORNING...THERE IS ENOUGH TO
SUPPORT ELEVATED CONVECTION. IN ADDITION...CORFIDI VECTORS ARE
POINTING SOUTH TONIGHT INTO THE LOW-LEVEL JUST SUGGESTING SOME
BACK BUILDING POTENTIAL OF THE MESOSCALE BETA ELEMENTS. WITH ALL
OF THIS CONSIDERED...WE HAVE ISSUED A FLASH FLOOD WATCH FOR THE
AREAS THREATENED BY HEAVY RAIN AND AREAS WHICH HAD HEAVY RAINFALL
LAST NIGHT.
