AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
711 AM CDT WED MAY 25 2011

...UPDATED FOR THE 12Z AVIATION DISCUSSION...

.DISCUSSION...
MAIN FOCUS REVOLVES AROUND LARGE UPPER LEVEL SYSTEM CURRENTLY
SPINNING ACROSS CENTRAL KANSAS...WITH THE SYSTEM NEARLY STACKED AS
THE SFC LOW SITUATED ACROSS CENTRAL/SOUTH CENTRAL KANSAS AS WELL.
INITIAL BANDS OF PRECIPITATION CURRENTLY PUSHING THROUGH THE AREA
WITH SOME HEAVIER RAINFALL WITH THE EMBEDDED THUNDERSTORMS. AS
SYSTEM SLOWLY LIFTS NORTHEASTWARD INTO NORTHERN MISSOURI BY LATE
THIS AFTERNOON/EARLY EVENING...EXPECT CURRENT BAND TO CONTINUE TO
TRACK NORTH NORTHWESTWARD THROUGH THE CWA. FORCING TO REMAIN IN
PLACE ACROSS THE CWA THROUGHOUT MOST OF THE DAY...PARTICULARLY
ACROSS NORTHWESTERN HALF OF THE CWA. EXPECT ACTIVITY TO BE A LITTLE
MORE SPOTTY ACROSS THE SOUTH THIS MORNING...WITH ADDITIONAL
REDEVELOPMENT ACROSS THE SOUTHEAST THIS AFTERNOON AS SFC WARM FRONT
NEARS THE CWA. CURRENTLY MODELS BRING FRONT JUST UP TO THE
BORDER...WITH INSTABILITY EXPECTED TO BE GREATEST IN THAT AREA.
THEREFORE WITH MUCH OF THE HEAVY RAIN THREAT WAINING ACROSS THE CWA
WITH THE EXCEPTION OF THE FAR SOUTHEAST WHERE REDEVELOPMENT IS
EXPECTED LATER TODAY...WILL CANCEL FLASH FLOOD WATCH FOR MUCH OF THE
SOUTHWEST/SOUTH CENTRAL CWA. ANY SEVERE POTENTIAL ALSO RELEGATED TO
THE FAR SOUTHEASTERN CWA IN VICINITY OF THE SFC FRONT/WARM FRONT
ALOFT. OTHER CONCERN TODAY INTO TONIGHT WILL BE ON WINDS...WITH A
TIGHTENING OF THE SFC PRESSURE GRADIENT EXPECTED AS THE SFC LOW
DEEPENS AND PUSHES SOUTH OF THE AREA. LOW LEVEL WINDS...AND SFC
WINDS EXPECTED TO PICK UP INTO THE 20 TO 30 KT RANGE...WITH WINDS
JUST OFF THE SURFACE IN THE 30 TO 40 KT RANGE. NAM...SREF...AND RUC
SOUNDINGS IN BUFKIT ALL SHOWING A VERY SHALLOW MIXED LAYER WITH WIND
ADVISORY CRITERIA WINDS POSSIBLE. AS THE SYSTEM PUSHES TO THE SOUTH
AND EAST OF THE AREA...ALSO GETTING SOME CAA/SUBSIDENCE. INTO THIS
EVENING WINDS STRONGEST ALOFT/GRADIENT TIGHTEST ACROSS
CENTRAL/SOUTHERN CWA. NOT THE BEST TIMING TO GET WIND ADVISORY
CRITERIA...BUT WITH THE CLOUDS/PRECIPITATION EXPECTED SHOULD KEEP
THE ATMOSPHERE FROM DECOUPLING AND EXPECT THE STRONGER WINDS/GUSTS
TO CONTINUE ACROSS THE AREA. THEREFORE WILL ALSO ISSUE A WIND
ADVISORY ACROSS THE NORTHERN CWA FOR LATE THIS MORNING INTO EARLY
EVENING...AND FOR THIS AFTERNOON INTO TONIGHT FOR THE SOUTHERN CWA.
SYSTEM TO CONTINUE TO WORK ITS WAY EASTWARD TONIGHT...WITH
RAIN/CLOUDS DECREASING FROM NORTHWEST TO SOUTHEAST ACROSS THE CWA.
MAY HAVE AN ISOLATED SHOWER LINGERING INTO THURSDAY MORNING ACROSS
THE FAR SOUTHEAST...OTHERWISE HIGH PRESSURE BUILDS INTO THE AREA FOR
THURSDAY INTO THURSDAY NIGHT WITH MAINLY DRY CONDITIONS. MUCH COOLER
AIR MOVES IN BEHIND THIS SYSTEM WITH H85 TEMPS DROPPING INTO THE
SINGLE DIGITS ABOVE FREEZING...WITH HIGHS ONLY EXPECTED IN THE 60S
FOR MUCH OF THE AREA THURSDAY INTO FRIDAY. ANOTHER UPPER LEVEL
TROUGH MOVES OUT OF THE ROCKIES INTO THE NORTHERN PLAINS SENDING A
WARM FRONT ACROSS THE AREA FRIDAY INTO FRIDAY NIGHT WITH THE NEXT
CHANCE FOR PRECIPITATION. THIS SYSTEM SLIDES OFF TO THE NORTH AND
EAST...AND ANOTHER UPPER LEVEL TROUGH DIGS INTO THE INTERMOUNTAIN
WEST FOR THE WEEKEND SETTING UP SOUTHWEST FLOW ALOFT...AND NEAR
STATIONARY BOUNDARY ASSOCIATED WITH LEE SIDE LOW PRESSURE SETTING UP
ACROSS THE NORTHERN CWA. ENERGY EJECTING OUT OF THE WESTERN US
TROUGH COULD SET THE STAGE FOR SOME MAINLY OVERNIGHT CONVECTION
SATURDAY NIGHT AND SUNDAY NIGHT. OTHERWISE A WARMING TREND EXPECTED
INTO THE WEEKEND WITH H85 TEMPS RETURNING INTO THE TEENS CELSIUS
WITH NEAR AVERAGE OR ABOVE AVERAGE MAX TEMPS BY LATE INTO WEEKEND
INTO MEMORIAL DAY.

&&

.HYDROLOGY...
A POWERFUL UPPER LEVEL WAVE OVER CENTRAL KANSAS WITH A SURFACE WARM
FRONT DRAPED ACROSS THE IA/MO BORDER WILL SLIDE EAST TODAY. A ROUND
OF THUNDERSTORMS MOVED THROUGH THE AREA OVERNIGHT PRODUCING SOME
HEAVY RAINFALL WITH 1HR FLASH FLOOD GUIDANCE REMAINING AROUND AN
INCH OR LESS ACROSS PORTIONS OF SOUTH CENTRAL AND SOUTHEASTERN IOWA.
WITH ADDITIONAL THUNDERSTORM DEVELOPMENT EXPECTED LATER TODAY...AND
THE THREAT FOR HEAVY RAINFALL CONTINUING INTO THIS EVENING...MOIST
SOIL CONDITIONS...AND LIMITED VEGETATION IN AGRICULTURAL LANDS...THE
POTENTIAL EXISTS FOR FLASH FLOODING THIS AFTERNOON INTO THIS EVENING
ACROSS PORTIONS OF SOUTH CENTRAL AND SOUTHEAST IOWA.

&&

.AVIATION...25/06Z
WIDESPREAD MVFR AND IFR CONDITIONS ARE EXPECTED MUCH OF TODAY WITH
SHOWERS AND A FEW THUNDERSTORMS LINGERING THROUGH MUCH OF THE DAY.
KOTM AND TO A LESSER EXTENT KDSM MAY BREAKOUT INTO VFR CONDITIONS
FOR A PERIOD TODAY BEFORE DROPPING BACK TO MVFR AND IFR. WINDS WILL
INCREASE FROM THE NORTHEAST TODAY FROM NORTH TO SOUTH AND BECOME
QUITE GUSTY BEFORE DIMINISHING LATE TONIGHT. CLEARING SKIES WILL
ALSO ARRIVE TONIGHT OVER THE NORTH INITIALLY AND REACHING KOTM LATE
IN THE PERIOD.

&&
