Area forecast discussion, Apr 9, 6:56 PM CDT, 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
656 PM CDT TUE APR 9 2013

.SHORT TERM.../TONIGHT /...
ISSUED AT 404 PM CDT TUE APR 9 2013

SFC LOW SITUATED OVER OKLAHOMA WITH AN INVERTED TROF AXIS EXTENDING
NORTHEASTWARD INTO SOUTH CENTRAL/SOUTHEASTERN IOWA. WEAK
BOUNDARY/COLD FRONT DROPPING SOUTHEAST ACROSS THE CWA...WITH LOW CIGS
AND LIGHT DRIZZLE/SHOWERS BEHIND IT. NEXT FEW WAVES OF ENERGY
LIFTING NORTHEASTWARD FROM THE BASE OF THE TROUGH LATE THIS
AFTERNOON INTO TONIGHT. FIRST ONE CURRENTLY RESPONSIBLE FOR AREA OF
THUNDERSTORMS ACROSS EASTERN NEBRASKA WHICH COULD CONTINUE TO
PROGRESS EASTWARD AND COULD REACH OUR WESTERN CWA BY EARLY EVENING.
OTHERWISE STRONGER PUSH OF ENERGY TO LIFT UP TOWARD THE CWA BY LATE
THIS EVENING INTO LATE TONIGHT...WITH ANOTHER ROUND
SHOWERS/THUNDERSTORMS EXPECTED TO SPREAD ACROSS THE CWA.
TEMPERATURES ACROSS THE NORTH ALREADY CLOSE TO FREEZING AND EXPECTED
TO DROP A FEW DEGREES OVERNIGHT. WARM LAYER ALOFT REMAINS...SO
INCREASINGLY LIKELY CHANCE FOR SOME RAIN CHANGING TO FREEZING RAIN
EXPECTED ACROSS NORTHERN CWA AFTER MIDNIGHT. THEREFORE WILL BE
ISSUING A WINTER STORM WARNING FOR NORTHERN CWA...WHERE SOME ICE
ACCRUAL IS POSSIBLE LATE TONIGHT COMBINED WITH ADDITIONAL WINTRY
PRECIPITATION LATER WEDNESDAY. FOR NOW...LOOKS LIKE ICE
ACCUMULATIONS OF AROUND A FEW HUNDREDTHS TO POSSIBLY AS MUCH AS A
TENTH OF AN INCH OF ICE IS POSSIBLE THROUGH SUNRISE.

.LONG TERM.../WEDNESDAY THROUGH TUESDAY/...
ISSUED AT 404 PM CDT TUE APR 9 2013

CURRENT SYSTEM WILL REMAIN PROBLEMATIC THE NEXT SEVERAL DAYS.
COLDER AIR CONTINUES TO FILTER INTO THE FORECAST AREA WITH
TEMPERATURES IN THE MID 30S ALREADY OVER THE NORTHWEST WHILE MID
70S REMAIN OVER THE FAR SOUTH. BOUNDARY WILL CONTINUE TO SINK
SOUTH THROUGH THE PERIOD WITH MAINLY AT OR BELOW FREEZING
TEMPERATURES WEDNESDAY AND THURSDAY OVER THE NORTH. WARM NOSE
ALOFT REMAINS FOR A PERIOD WITH FREEZING RAIN POTENTIAL CONTINUING
OVER THE NORTH. CERTAINLY POTENTIAL OVER THE NORTHWEST FOR ONE
QUARTER INCH OR MORE ICE POSSIBLE THROUGH NOON WEDNESDAY.
PRECIPITATION WILL GRADUALLY TRANSITION TO SLEET OR SNOW AS THE
COLD DEPTH INCREASES AND STRENGTHENS BELOW THE WARM NOSE ACROSS
THAT REGION AND EVENTUALLY CHANGE TO ALL SNOW AS THE LAST
SIGNIFICANT WAVE MOVES THROUGH WEDNESDAY NIGHT AND THURSDAY. FOR
THIS REASON...WILL ISSUE A SMALL WINTER STORM WARNING ACROSS THE
FAR NORTHWEST FROM MIDNIGHT TONIGHT THROUGH NOON THURSDAY. 3 TO 6
INCHES OF SNOW IS POSSIBLE OVER THE WARNED AREA BY NOON THURSDAY.

FARTHER SOUTH...CURRENTLY DO NOT HAVE A BUFFER WINTER STORM WATCH
WHICH STILL MAY BE NEEDED. HOWEVER THERMAL PROFILES REMAIN WARM
ENOUGH THAT THE WINTRY PRECIPITATION SHOULD HOLD OFF UNTIL A
PERIOD OF CHANGE OVER TO SNOW MAINLY ALONG AND NORTHWEST OF A
WATERLOO TO DES MOINES TO ATLANTIC LINE. THE SYSTEM FINALLY SHIFTS
OUT OF THE AREA THURSDAY NIGHT INTO FRIDAY.

COOL ON FRIDAY THEN GRADUAL WARMING INTO THE WEEKEND. ANOTHER
SYSTEM WILL APPROACH FOR SATURDAY NIGHT AND SUNDAY WITH THE NEXT
CHANCE FOR PRECIPITATION. GENERALLY COOL AND BELOW NORMAL FOR
EARLY NEXT WEEK.

&&

.AVIATION...09/00Z
ISSUED AT 656 PM CDT TUE APR 9 2013

OUTSIDE OF KOTM WHICH IS STILL VFR...WIDESPREAD IFR CONDITIONS
EXIST ACROSS THE STATE ARE ARE EXPECTED TO CONTINUE THROUGH THE
PERIOD. KOTM SHOULD BECOME IFR SHORTLY AS WELL. SYSTEM AFFECTING
IA WILL CHANGE LITTLE INTO WED WITH STAGNANT WEATHER RESULTING IN
OCCASIONAL SHOWERS AND A FEW THUNDERSTORMS. HAVE ONLY TIMED
THUNDER AT MOST SITES WITH STORMS JUST CROSSING MO RIVER...BUT
OTHER PERIODS OF THUNDER ARE POSSIBLE AS WELL AND WILL BE ADDED
ONCE CONFIDENCE IN TIMING AND LOCATION INCREASES. THESE
AFOREMENTIONED STORMS WILL LIKELY MISS KOTM...BUT OTHER CHANCES
INCREASE WED AFTERNOON WITH LOW PRESSURE PASSING ACROSS MO.

&&

.HYDROLOGY...
ISSUED AT 404 PM CDT TUE APR 9 2013

OBSERVED AND FORECAST RAINFALL ARE NOT EXPECTED TO RESULT IN
WIDESPREAD SIGNIFICANT FLOOD IMPACTS ACROSS CENTRAL IOWA FOR THE
NEXT FEW DAYS. THE THREAT OF FLOODING AND FLASH FLOODING IS NOT
PRESENTLY HIGH ENOUGH TO WARRANT A FLOOD WATCH. HIGHER PROBABILITIES
OF FLOODING EXIST TO THE EAST OF THE CWA...ACROSS THE DVN AND ARX
CWAS.

THE FLASH FLOOD THREAT IS MINIMAL OVER THE NEXT 24-48 HRS CENTRAL
AND NORTH. SOME SHORT-TERM LOCALIZED MINOR FLOODING...INCLUDING SOME
MINOR URBAN FLOODING...MAY OCCUR HOWEVER. COMPARISON OF PRESENT
GRIDDED FLASH FLOOD GUIDANCE TO WPC QPF ENSEMBLES YIELDS LOW
PROBABILITIES OF REACHING OR EXCEEDING FLASH FLOOD GUIDANCE ACROSS
THE NORTHWEST TWO THIRDS OF THE CWA. BEST CHANCE FOR FLASH
FLOODING IS OVER THE FAR EAST AND SOUTH AND WILL MATCH SURROUNDING
OFFICES WITH A WATCH ACROSS THOSE AREAS.

A SLIGHTLY ELEVATED FLASH FLOOD THREAT DOES EXIST IN OUR
CWA...HOWEVER...NORTH OF US HWY 18. SOME GROUND FROST STILL EXISTS
IN THAT AREA...SO RUNOFF MAY BE HIGHER THERE THAN ELSEWHERE FOR
SIMILAR AMOUNTS OF RAINFALL. STILL...THOUGH...THE FLOOD THREAT THERE
IS NOT HIGH ENOUGH TO WARRANT A FLASH FLOOD WATCH.

THE RIVER FLOOD THREAT IS GENERALLY LOW OVER THE NEXT 24-48 HRS.
BEST CHANCES FOR QPF ENSEMBLE HYDROGRAPHS SUGGEST THAT ONLY A
COUPLE RIVER FORECAST POINTS MAY APPROACH OR REACH FLOOD STAGE. A
FEW RIVER FORECAST POINTS MAY APPROACH OR EXCEED BANKFULL.
