AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1148 PM CDT TUE APR 16 2013

.UPDATE...
ISSUED AT 1003 PM CDT TUE APR 16 2013

HAVE UPDATED THE GRIDS TO DELAY ONSET OF PRECIPITATION UNTIL
MAINLY AFTER MIDNIGHT FOR NOW AS MOISTURE TAKING ITS TIME MOVING
INTO THE AREA. CLOUDS BASES LOWERING ACROSS MISSOURI...SO
ANTICIPATE CEILINGS LOWERING ACROSS IOWA OVER THE NEXT FEW HOURS
AS LOWER LEVELS BEGIN TO SATURATE. INITIAL IMPULSE EJECTING
NORTHEASTWARD TOWARD THE REGION...ALSO ARRIVING LATER SO BETTER
CHANCES FOR ONSET OF WIDESPREAD PRECIPITATION MORE TOWARD LATE
TONIGHT INTO EARLY WEDNESDAY MORNING.

&&

.SHORT TERM.../TONIGHT /...
WEAK RIDGE OF HIGH PRESSURE OVER THE STATE WILL DRIFT OFF TO THE
EAST WITH WINDS GRADUALLY BECOMING MORE NE-ELY. LOWER CLOUDS WILL
GRADUALLY PUSH NORTH AS LLJ PICKS UP STEAM OVERNIGHT. INITIAL
ISOLATED SHOWERS WILL BE SUPPRESSED TO THE SOUTH OF THE CWA FOR A
WHILE THIS EVENING...THEN BEGIN TO LIFT NORTH AS THE LLJ PUSHES
NORTH AND STRONG THETA-E ADVECTION WILL PUSH INTO THE STATE. THIS
WILL DESTABILIZE THE ATMOSPHERE WITH SEVERAL HUNDRED J/KG OF CAPE
AVAILABLE BY MORNING. TRANSITIONED SHOWERS INTO ISOLATED
TSRA...THEN GENERAL THUNDER OVER THE SOUTH BY LATER TONIGHT. TEMPS
WILL NOT CHANGE A WHOLE LOT TONIGHT AFTER THE INITIALLY DROP. WITH
STRONG WAA IN PLACE AND CLOUDS INCREASING...DO NOT EXPECT TO SEE
LOWS FALL BELOW THE MID 30S TO LOW 40S.

.LONG TERM.../WEDNESDAY THROUGH TUESDAY/...
THE COOL AND ACTIVE PATTERN THAT HAS BEEN IN PLACE FOR MOST OF THE
LAST TWO MONTHS OR SO WILL CONTINUE FOR THE COMING WEEK. A LONG
DURATION PRECIPITATION EVENT REMAINS ON TAP FROM TOMORROW INTO
FRIDAY FOR THE ENTIRE AREA. INITIALLY THIS WILL BE IN THE FORM OF
RAIN AND THUNDERSTORMS...THEN AFTER A TROUGH MOVES ACROSS THE AREA
WEDNESDAY NIGHT COOLER AIR WILL STREAM IN FROM THE
NORTHWEST...RESULTING IN A CHANGEOVER TO SNOW ON THURSDAY NIGHT
BEFORE THE PRECIPITATION ENDS ON FRIDAY. THIS POSES SEVERAL
POTENTIAL HAZARDS.

FIRST...THERE IS AT LEAST SOME POSSIBILITY OF SEVERE WEATHER ON
WEDNESDAY AFTERNOON INTO EARLY WEDNESDAY NIGHT ACROSS OUR
SOUTHEASTERN COUNTIES. SPC HAS OUTLOOKED THIS AREA WITH A 30
PERCENT PROBABILITY BUT IT IS CONDITIONAL. THE INVERTED TROUGH
STRETCHING UP INTO THE AREA WILL BE REFLECTED IN A SHARPENING
SURFACE BOUNDARY SOMEWHERE ACROSS SOUTHEASTERN IOWA BY WEDNESDAY
EVENING AND DYNAMIC PARAMETERS ARE FAVORABLE FOR MESOCYCLONE
DEVELOPMENT. HOWEVER...ALL INDICATIONS ARE THAT WITH OVERCAST
SKIES AND A VERY STRONG LOW LEVEL INVERSION IN PLACE INSTABILITY
WILL BE LIMITED AND ELEVATED. THE MOST LIKELY SEVERE WEATHER
THREAT WOULD BE WET HAIL...BUT AN ISOLATED DOWNBURST IS ALSO
POSSIBLE.

SECOND...MOISTURE IS ABUNDANT WITH THIS STORM SYSTEM AND GIVEN ITS
DURATION FAIRLY HEAVY RAINFALL ACCUMULATIONS ARE
EXPECTED...PROBABLY IN THE RANGE OF 2 TO 3 INCHES ACROSS MUCH OF
THE AREA WITH LOCALLY HIGHER AMOUNTS. THIS RESULTS IN FLOODING
CONCERNS...PARTICULARLY IN SOME OF THE RIVERS...HOWEVER IT IS
LIKELY THAT MOST OF THESE AMOUNTS WILL COME OVER A LONG PERIOD
RATHER THAN IN A SHORT PERIOD OF TIME. GIVEN THE ANTECEDENT
CONDITIONS IN PLACE...ANY FLASH FLOODING SHOULD BE LOCALIZED
AROUND HEAVIER THUNDERSTORMS AND URBAN AREAS. THEREFORE A FLASH
FLOOD WATCH HAS NOT BEEN ISSUED AT THIS TIME.

FINALLY...THE SNOWFALL COMBINED WITH STRENGTHENING WINDS COULD BE
A PROBLEM LATE THURSDAY NIGHT INTO FRIDAY MORNING ACROSS OUR NORTH
AND NORTHWEST. AT THIS TIME SNOWFALL AMOUNTS ARE HIGHLY UNCERTAIN
BUT LIGHT ACCUMULATIONS APPEAR PROBABLE IN THESE AREAS. WINDS OF
25 TO 30 MPH AT TIMES WITH HIGHER GUSTS WOULD LIKELY RESULT IN
REDUCED VISIBILITY AS SNOW IS FALLING...BUT DRIFTING ISSUES SHOULD
BE MITIGATED BY THE AIR/SURFACE TEMPERATURES AND RELATIVELY LOW
SNOWFALL AMOUNTS. THIS WILL CERTAINLY BEAR MONITORING OVER THE
NEXT COUPLE OF DAYS...AND A WIND ADVISORY AND/OR WINTER WEATHER
ADVISORY MAY BE JUSTIFIED AT SOME POINT.

THE LARGE STORM SYSTEM WILL PULL AWAY QUICKLY TO THE EAST ON
FRIDAY...AFTER WHICH A BRIEF RESPITE WILL TAKE PLACE WITH WEAK
RIDGING BUILDING ACROSS THE AREA ON FRIDAY NIGHT AND SATURDAY. IT
WILL NOT LAST LONG HOWEVER...AS ANOTHER LONGWAVE TROUGH WILL
BECOME HUNG UP TO OUR WEST RESULTING IN MORE EXTENDED
PRECIPITATION CHANCES FROM SUNDAY THROUGH TUESDAY OF NEXT WEEK. AT
THIS TIME IT APPEARS THAT TEMPERATURES WILL BE WARM ENOUGH TO KEEP
THE PRECIPITATION MOST OR ALL RAIN DURING THAT TIME...BUT IT WILL
ALSO KEEP THE WEATHER COOL AND DAMP. IN FACT OUTSIDE OF DAVIS
COUNTY NO 60 DEGREE OR HIGHER TEMPERATURES ARE CURRENTLY FORECAST
WITHIN THE CWA IN THE NEXT SEVEN DAYS WHICH IS REMARKABLE FOR THIS
LATE IN THE SPRING.

.AVIATION...17/06Z
 ISSUED AT 1148 PM CDT TUE APR 16 2013

VFR CIGS AT ALL TAF SITES FOR NOW...WITH CIGS STILL EXPECTED TO
LOWER TO MVFR AND THEN IFR AS MOISTURE INCREASES AND PRECIPITATION
OVERSPREADS THE AREA LATE TONIGHT INTO WEDNESDAY. VSBYS STILL
EXPECTED TO DIP TO MVFR AND POSSIBLE IFR CONDITIONS IN HEAVIER
SHOWERS AND THUNDERSTORMS AND DUE TO SOME FOG WITH THE ABUNDANT
LOW LEVEL MOISTURE. INSTABILITY EXPECTED TO BE GREATEST AROUND THE
SOUTHERN/EASTERN TAF SITES SO HAVE ONLY INCLUDED VCTS AT
KALO...KDSM...AND KOTM...HOWEVER CANNOT RULE OUT AN ISOLATED
THUNDERSTORM AT ANY TAF SITE.
