AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
314 AM CDT SUN JUN 5 2011

.SHORT TERM /TODAY/...
EXPECT EARLY MORNING PRECIPITATION TO PERSIST INTO BEGINNING OF
PERIOD...ESPECIALLY ACROSS SOUTH...BUT WILL BEGIN TO DECREASE AS
AXIS OF THETA-E WEAKENS AND PUSHES NORTHEAST. HAVE THEREFORE
INCLUDED SLIGHT CHANCE MENTION FOR SOUTHERN CWA IN THE MORNING. COLD
FRONT HAS BECOME LESS WELL DEFINED...BUT IS STILL NEAR THE
IOWA/MISSOURI BORDER. THE FRONT WILL BEGIN TO LIFT NORTHWARD
THROUGHOUT THE DAY...BRINGING CHANCES FOR THUNDERSTORMS DEVELOPMENT
ALONG AND AHEAD OF IT...AS CAPE VALUES OF 2000-3000 J/KG SURGE NORTH
WITH FRONT. SHEAR VALUES ALSO LOOK FAVORABLE FOR STORMS THAT DEVELOP
TO HOLD TOGETHER...WHICH COULD LEAD TO A RISK FOR SEVERE WEATHER.
STEEPER LAPSE RATES COULD ALLOW FOR SEVERE HAIL...AND DAMAGING
WINDS. HAVE ONLY INCLUDED A CHANCE MENTION FOR STORMS ACROSS THE
SOUTH IN THE AFTERNOON. FRONT WILL CONTINUE TO DECAY WHICH MAY NOT
BE ENOUGH FORCING TO GET STORMS TO FIRE.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
MAIN STORY FOR THE NEXT SEVERAL DAYS WILL BE THE RETURN OF THE WARM
FRONT AND HOT WEATHER COMING UP FOR MONDAY AND TUESDAY. PATTERN
REMAINS BLOCKED BY RIDGE OVER THE CENTRAL US FOR NOW. MOISTURE POOL
JUST TO THE SOUTH OF THE STATE AT H850 WITH VERY WEAK RETURN FLOW ON
THE BACK SIDE OF THE BOUNDARY EARLY SUNDAY. THE FRONT WILL GRADUALLY
LIFT NORTH TONIGHT WITH SOME LIFT EXPECTED AS THE FRONT MIGRATES
BACK NORTH OF THE REGION ON MONDAY IN RESPONSE TO DEEPENING LOW
PRESSURE OVER THE HIGH PLAINS. THIS SHOULD PRODUCE SOME SHOWERS AND
THUNDERSTORMS OVER CENTRAL AND NORTHERN IOWA TONIGHT AND EARLY
MONDAY...BEFORE MIXING TAKES OVER AND DIMINISHES THE LITTLE LOW
LEVEL JET SUPPORT THAT OCCURS TONIGHT. THOUGH H850 TEMPS HAVE COOLED
INTO THE UPPER TEENS AS OF 00Z SUN...TEMPS RAPIDLY WARM OVER THE
SOUTHWEST AND SOME OF THIS WILL BE PULLED NORTHEAST BY MONDAY.
MODELS SUGGESTING H850 TEMPS TO REACH THE LOW TO MID 20C RANGE BY
MONDAY AFTERNOON...POSSIBLY TUESDAY AS WELL. BY MONDAY AFTERNOON
HIGHS WILL REACH THE MID 90S WITH DEW POINTS IN THE MID TO UPPER 60S
AS SOME MIXING IS EXPECTED. THIS WILL PUSH HEAT INDICES INTO THE MID
TO UPPER 90 RANGE...POSSIBLY REACHING 100 IN THE SOUTH AND WEST.
GIVEN THE EARLY OCCURRENCE OF SUCH SUMMER LIKE CONDITIONS...A HEAT
ADVISORY MAY BE NEEDED TO ALERT THE PUBLIC.  FOR NOW...WILL LET THE
DAY SHIFT LOOK AT THIS ONCE MORE PRIOR TO ANY HEADLINES. AT
H700...TEMPS WILL WARM TO +10C TO +12C BOTH MONDAY AND TUESDAY AND
WITH LITTLE FORCING OR SFC CONVERGENCE TO SPEAK OF THE AREA SHOULD
REMAIN QUIET. THE ONLY CHANCE FOR ANY STORMS WILL LIKELY BE OVER THE
FAR NORTH...GIVEN THE PROXIMITY OF THE FRONT ACROSS SOUTHERN MN. FOR
NOW...WILL LEAVE DRY. LITTLE CHANGE IS EXPECTED ON TUESDAY WITH
SIMILAR CONDITIONS... THOUGH SLIGHTLY COOLER ALOFT. ALONG WITH THIS
SOME CLOUDS ARE EXPECTED AND HAVE TRIMMED HIGHS A FEW DEGREES. WINDS
INCREASE ALOFT ON TUESDAY AND WILL HAVE LITTLE TROUBLE MIXING IN THE
AFTERNOON. THIS MAY ALSO TEND TO HOLD TEMPS DOWN A BIT. WINDS SHOULD
APPROACH 30 MPH AT TIMES WITH HIGHER GUSTS CENTRAL AND WEST. AS THE
TROUGH WEST DEEPENS ON TUESDAY NIGHT AND WEDNESDAY...SOME SCT
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP. BOTH MONDAY NIGHT
AND TUESDAY NIGHT LOOK RATHER WARM...WITH LOWS IN THE LOWER 70S.
THIS WILL LEAD TO ANOTHER WARM DAY ON WEDNESDAY SOUTH PRIOR TO
FRONTAL ARRIVAL AS HIGHS REACH THE MID 80S NORTH TO LOWER 90S SOUTH.
BY WED EVENING STORMS FIRING ALONG THE BOUNDARY SHOULD HELP PUSH IT
SOUTH OF THE STATE WITH A BREAK ON THE WAY FOR THURSDAY PRIOR TO THE
FRONT LIFTING BACK TO THE NORTH AGAIN FRIDAY AND SATURDAY. WITH HOT
DOME TO THE SOUTH AND MOISTURE POOL GOING NOWHERE...REPEATED
RAINFALL FROM THURSDAY THROUGH SATURDAY MAY RESULT IN HEAVY PRECIP
AMOUNTS OVER CENTRAL OR SOUTHERN IOWA. AT THIS POINT...RATHER
DIFFICULT TO FAVOR ONE AREA OVER ANOTHER. SOME CONCERNS FOR NOW IS
THAT THE MODELS MAY BE TOO BULLISH ON KEEPING THE FRONT IN SOUTHERN
IA.  THIS ALL HINGES ON WHETHER A STRONGER SFC LOW DEVELOPS OVER THE
SOUTHERN PLAINS AND HOW FAR NORTH THAT LOW TRACKS. THE 00Z GEM HAS
THE LOW MUCH FARTHER SOUTH...COMPARED TO THE GFS/EURO MODEL. TEMPS
WILL COME DOWN ONCE THE CONVECTION BEGINS...THOUGH WITH HUMIDITY
LEVELS INCREASING THE COMFORT METER WILL PROBABLY REMAIN LOW. A
STRONGER NORTHERN STREAM SHORTWAVE BY SATURDAY SHOULD HELP TO PUSH
ACTIVITY EAST OF REGION FOR A DAY OR TWO.

&&

.AVIATION...05/06Z
SOME FOG EXPECTED TO CONTINUE AT KOTM THROUGH THE OVERNIGHT
HOURS...WITH POSSIBILITY OF SOME ADDITIONAL CONVECTION DEVELOPING
ACROSS CENTRAL IOWA LATE TONIGHT AND MOVING EAST SOUTHEAST INTO KDSM
AND KOTM. STILL UNCERTAIN IF IT WILL DEVELOP SO HAVE MENTIONED WITH
A CB FOR NOW. OTHERWISE OTHER TIME PERIOD IS LATE THIS AFTERNOON
INTO THE EARLY EVENING WHEN STORMS EXPECTED TO DEVELOP ALONG SFC
BOUNDARY LIFTING NORTHWARD THROUGH THE STATE MAINLY IMPACTING KOTM
AND KDSM AGAIN. LIGHT AND VARIABLE WINDS TO SHIFT AROUND TO THE EAST
TO SOUTHEAST THROUGH THE PERIOD.

&&

.DMX WATCHES/WARNINGS/ADVISORIES...NONE.
