AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1232 PM CDT WED APR 17 2013

.SHORT TERM.../TODAY/
ISSUED AT 436 AM CDT WED APR 17 2013

THE COMBINATION OF A LOW LEVEL JET INCREASING ACROSS SOUTHERN IOWA
AND STRONG THETA-E ADVECTION PUSHING ACROSS THE STATE HAS CAUSED
SHOWERS AND THUNDERSTORMS TO BLOSSOM OVERNIGHT AND QUICKLY SPREAD
INTO SOUTHERN IOWA.  THESE STORMS WILL PUSH NORTHEAST ACROSS MUCH OF
THE AREA THROUGH THE MORNING.  THE BEST INSTABILITY REMAINS SOUTH OF
IOWA...ACROSS KANSAS AND CENTRAL MO.  THIS WILL WORK ITS WAY INTO
IOWA AS WELL BUT PROBABLY NOT UNTIL LATER MORNING AND AFTERNOON.
UNTIL THEN STORMS SHOULD BEHAVE THEMSELVES...PRODUCING LIGHT TO
MODERATE RAINFALL AND PERHAPS SOME SMALL HAIL.

DURING THE AFTERNOON INTO THE EVENING A BUILDING UPPER RIDGE TO OUR
EAST AND THE WELL ADVERTISED DEEPENING TROUGH OVER THE SOUTHWEST
WILL BRING A DEEP SOUTH TO SOUTHWEST FLOW ACROSS THE STATE AS WELL
AS DEEPER MOISTURE.  AT THE SURFACE AN INVERTED TROUGH WILL SET UP
FROM ROUGHLY LAMONI THROUGH CHARLES CITY.  THERE WILL BE DECENT
SHEAR ALONG THAT SURFACE BOUNDARY THAT WILL SET UP IN THIS AREA SO I
AM EXPECTING STORMS TO SORT OF FOCUS ON THAT BOUNDARY AND WHILE THE
STRONGER STORMS WILL REMAIN SOUTH OF THE STATE...WE CANNOT RULE OUT
SOME STORMS CAPABLE OF LARGE HAIL OR STRONG TO DAMAGING WIND.  NOT
EXPECTING A BIG SEVERE WEATHER DAY HERE AS STORMS WILL REMAIN
ELEVATED BASED ON SOUNDINGS.

HEAVY RAIN IS ALSO A CONCERN.  WE HAVE BEEN GETTING DECENT RAINFALL
OF LATE AND WITH QPF VALUES OF A HALF TO 6 TENTHS OF AN INCH THIS
MORNING AND AT LEAST THAT THIS AFTERNOON WITH MORE HEAVY RAIN
EXPECTED TONIGHT SOME POTENTIAL FOR FLOODING EXISTS.  WE WILL BE
ISSUING A FLASH FLOOD WATCH ACROSS MUCH OF THE SOUTHEAST BEGINNING
AT NOON.  MODERATE TO HEAVY RAIN SHOULD NOT BEGIN BEFORE MID TO LATE
AFTERNOON BUT THIS MORNINGS RAIN WILL SATURATE SOILS AND PRIME
THINGS FOR LATER.

.LONG TERM.../TONIGHT THROUGH TUESDAY/
ISSUED AT 436 AM CDT WED APR 17 2013

VERY COMPLEX FORECAST EARLY IN THIS PERIOD WITH WINTER...HEAVY
RAIN AND SEVERE WEATHER ELEMENTS ALL IN PLAY. HEAVY RAIN AND
SEVERE WEATHER WILL INITIALLY BE THE CONCERN AS CONVECTION
CONTINUES TO DEVELOP ALONG AND AHEAD OF MATURING INVERTED TROUGH
WHICH IS EXPECTED TO REACH SRN IA BY LATE AFTERNOON. INSTABILITY
WILL NOT BE EXTREME WITH MUCAPES TYPICALLY AT OR BELOW 1000
J/KG...LIKELY ELEVATED. ALTHOUGH FAR SE SECTION MAY BRIEFLY GET
INTO THE WARM SECTOR...EXPECT MLCIN TO STAYING TOO HIGH TO GET
ANYTHING SURFACE BASED DUE TO PERSISTENT CLOUDS AND PRECIP. SEVERE
WEATHER POTENTIAL MAY WANE SOMEWHAT DURING THE EVENING AS
EFFECTIVE /1-6KM/ SHEAR DIMINISHES. HOWEVER HEAVY RAIN
THREAT...WHICH WOULD ALREADY BE IN PLACE...MAY INCREASE AS
CONVECTION TRAINS ALONG TROUGH INTO SOUTHEAST IOWA SO FLASH FLOOD
WATCH HAS BEEN ISSUED FOR THESE LOCATIONS. SEE HYDRO SECTION FOR
MORE INFORMATION.

PRECIPITATION MAY BRIEFLY DIMINISH SOMEWHAT INTO THURSDAY AS
SURFACE FEATURES EXIT AND LARGE SCALE FORCING TAKES A TEMPORARY
BREAK. HAVE LEANED TOWARD THE RECENT NAM AND ECMWF SOLUTIONS WHICH
SEEM FAIRLY SIMILAR WHILE THE GFS APPEARS TO BE SOMEWHAT OF A
SLOWER OUTLIER. WITH ALL THE CONVECTION AND LATENT HEAT RELEASE
CANNOT ARGUE WITH LOWER SURFACE PRESSURES BEING FARTHER NE BY THU
MORNING. MOST OF THE FORCING AND MOISTURE EARLY THU APPEARS TO BE
BELOW 3KM SUGGESTING LIGHT PRECIP AMOUNTS BUT WITH NO ICE
INTRODUCTION. THUS FREEZING RAIN MAY COME INTO PLAY NW WHERE TEMPS
WILL HOVER AROUND THE FREEZING MARK AS COLDER AIR CONTINUES TO
FILTER INTO THE STATE. IF SURFACE TEMPS DROP SUFFICIENTLY...AND
THATS A CONDITIONAL IF...WE MAY SEE SOME ADVISORY LEVEL ICING.
STUDIES HAVE SHOWN THAT SMALLER DROPS...WHICH WOULD BE THE CASE IN
THIS LIGHTER PRECIP/RELATIVELY SHALLOWER MOISTURE...AND BRISK WINDS
ENHANCE ICING. CONFIDENCE IN THERMAL PROFILE BEING FAVORABLE IS
NOT GREAT HOWEVER SO WILL MENTION IN HWO BUT NOT INCLUDE IN
ADVISORY AS OF YET.

BY LATER IN THE DAY THE LARGE SCALE FORCING SHOULD INCREASE HAD OF
THE PARENT SYSTEM..ESPECIALLY BY THE EVENING. WITH TEMPERATURES
JUST ABOVE FREEZING BY LATE AFTERNOON AND SUFFICIENT MOISTURE
DEPTH FOR ICE INTRODUCTION...PRECIP TYPE SHOULD FLIP TO EITHER
RAIN OR SNOW. BEST DENDRITIC FORCING LOOKS TO BE NORTH OF
FORECAST AREA BY THE TIME WE SWITCH TO SNOW NW SO COULD SEE AN
INCH OR TWO FAR NW BUT NOTHING TO JUSTIFY A HEADLINE AT THE
MOMENT. CONDITIONS MAY BRIEFLY DETERIORATE WITH LOW VISIBILITIES
DURING THE SNOW AND BRISK NW WINDS HOWEVER.

PATTERN REMAINS SIMILAR RIGHT INTO EARLY NEXT WEEK WITH DAMP AND
GENERALLY COOL CONDITIONS. PRECIP RETURNS TO THE FORECAST BY LATE
SATURDAY NIGHT AS WARM ADVECTION RETURNS. THIS WILL BE FOLLOWED BY
DEEPER FORCING WITH PASSAGE OF SURFACE SYSTEM LATE SUNDAY. LONG
WAVE TROUGH CONTINUES TO DEEPEN INTO EARLY NEXT WEEK WITH ANOTHER
SYSTEM MATURING THROUGH MID MS VALLEY...IN SOME WAYS SIMILAR TO
CURRENT SYSTEM. THIS WILL LIKELY BRING MORE WIDESPREAD TO SE IA
AND WITH MORE COOL TEMPERATURES.

&&

.AVIATION...17/18Z
IFR AND LOWER CONDITIONS WILL PREVAIL FOR MOST OF THE TAF PERIOD.
LARGE LOW STRATUS FIELD CURRENTLY EXTENDING ACROSS THE SOUTHWEST
HALF OF IA AND NEIGHBORING STATES WILL CONTINUE TO
EXPAND...ESPECIALLY AFTER DARK...ALONG WITH COVERAGE OF SHOWERS
AND THUNDERSTORMS LATER THIS AFTERNOON AND EVENING. HAVE TAKEN
BEST SHOT AT TIMING LOWERING TRENDS IN VSBY/CIGS AND ONSET OF
PRECIP/TS...HOWEVER THESE VARIABLES ARE QUITE UNCERTAIN TODAY AND
AMENDMENTS ARE ANTICIPATED. APPRECIABLE IMPROVEMENT WILL NOT OCCUR
UNTIL AT LEAST MID-MORNING THURSDAY.

&&

.HYDROLOGY...
ISSUED AT 436 AM CDT WED APR 17 2013

STORM MOTION BY LATE EVENING APPEARS TO BE PARALLEL TO THE FRONT
AT 40-50KTS SUGGESTING SERN IA MAY BE ON THE NRN FRINGE OF WHAT
RESEMBLES A MADDOX SYNOPTIC FLOODING EVENT. WITH PWS TO 1.5
INCHES...EXTREMELY ABOVE NORMAL...AND WARM CLOUD DEPTHS PUSHING
10KFT HAVE ISSUED A FLASH FLOOD WATCH FOR THESE LOCATIONS FROM
THIS AFTERNOON INTO TONIGHT. RAINFALL AMOUNTS BY DAYBREAK THU MAY
REACH 2-3 INCHES WITH LOCALLY HIGHER AMOUNTS POSSIBLE. WITH
GROUNDS STILL RELATIVELY MOIST THERE AND MAINLY DORMANT VEGETATION
RUNOFF WILL BE FAIRLY HIGH. RIVER FORECAST CENTER CONTINGENCY
FORECASTS FROM TUE SUGGEST SEVERAL RIVERS MAY REACH FLOOD STAGE
OVER THE EASTERN FORECAST AREA. CANDIDATES TO BE WATCHED WOULD BE
THE CEDAR RIVER AND THERE TRIBUTARIES AND THE DES MOINES RIVER
BELOW RED ROCK.
