AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
332 AM CDT SUN JUN 23 2013

.SHORT TERM.../TODAY /...
ISSUED AT 259 AM CDT SUN JUN 23 2013

.SHORT TERM /TODAY/...
CONCERNS FOR STRONG TO SEVERE THUNDERSTORMS AND HEAVY RAIN ARE THE
FOCUS FOR THIS FORECAST PERIOD. THE MODELS CONTINUE TO ADVERTISE
SOME OF THE WESTERN CONVECTION TO REACH THE AREA THIS MORNING AND
THEN DIMINISH AS IT TRACKS TO THE EAST THROUGH MID MORNING. A WAVE
ALONG THE BOUNDARY OVER NORTHWEST IOWA WILL TRACK EAST THIS MORNING
WITH THE SOUTHERN WAVE BEGINS TO PUSH NORTHEAST THIS AFTERNOON AND
TONIGHT. THIS WILL ENHANCE MOISTURE TRANSPORT NORTHEAST THROUGH THE
AFTERNOON AND EVENING. TEMPERATURES THIS MORNING ARE ABOUT 5 TO 7
DEGREES WARMER THAN EXPECTED...SO HAVE RAISED THE HIGHS OVER THE
SOUTH TO NEAR TO ABOVE 90 AGAIN TODAY. WITH SUFFICIENT INSTABILITY
STORMS WILL BEGIN TO REFIRE NORTH NEAR THE NOON HOUR OR EARLY
AFTERNOON AND BEGIN TO BUILD SOUTH. THE MODELS SUGGEST WE WILL SEE
SOME BACK BUILDING ALONG THE BOUNDARY TODAY AND THIS EVENING WHICH
WILL INCREASE THE POTENTIAL FOR HEAVY RAINFALL. THERE IS SOME
UNCERTAINTY AS TO WHERE THE GREATEST POTENTIAL FOR FLASH FLOODING IS
...BUT THE NORTH TWO THIRDS LOOK TO BE THE MOST AT RISK FOR
NOW...THE SOUTHERN AREAS MAY NEED TO BE ADDED YET TODAY...BUT THEY
CAN TAKE A BIT MORE WATER THAN THE REST OF THE AREA. RAINFALL TOTALS
OF 2 TO 4 INCHES OR MORE MAY BE POSSIBLE GIVEN POTENTIAL FOR BACK
BUILDING ALONG THE FRONT...WARM CLOUD DEPTHS ABOVE 10KFT...AND PWATS
OF 1.5 TO 2 INCHES OVER THE AREA. THE LATEST EURO MODEL SUGGESTS
THAT THE BULK OF THE ACTIVITY WILL TAKE PLACE DURING THE EVENING AND
OVERNIGHT HOURS WHILE THE MESO MODELS ARE HINTING AT AN EARLIER
START THIS AFTERNOON. WILL LEAN TOWARD EARLIER START FOR NOW...GIVEN
THE INSTABILITY EXPECTED BY THIS AFTERNOON. WINDS WILL BE GUSTY
TODAY PRIOR TO THE ONSET OF STORMS. STORMS COULD BRING HIGH WIND AND
SOME HAIL...ALONG WITH RAINFALL THREAT TODAY AND THIS EVENING.

.LONG TERM.../TONIGHT THROUGH FRIDAY/...
ISSUED AT 259 AM CDT SUN JUN 23 2013

FORECAST CONCERNS REVOLVE AROUND THUNDERSTORMS THROUGH TUESDAY.
UPPER LEVEL LOW ACROSS SOUTHERN CANADA WILL BE RESPONSIBLE FOR
SENDING NUMEROUS SHORTWAVES ACROSS THE UPPER RIDGE WHICH WILL
FLATTEN IT. THUNDERSTORMS ARE EXPECTED TO BE ONGOING FROM THIS
AFTERNOON ACROSS THE FORECAST AREA THEN BECOME RENEWED AS A LOW
LEVEL JET DEVELOPS WITH STRONG MOISTURE TRANSPORT INTO AN AREA OF
WARM ADVECTION NEAR A SLOW MOVING SURFACE BOUNDARY. SOME STRONG
STORMS ARE POSSIBLE THIS EVENING THEN TRANSITION INTO A HEAVY RAIN
THREAT. THE FRONTAL BOUNDARY FINALLY PUSHES EAST THROUGH MOST OF
THE FORECAST AREA BY MONDAY EVENING BUT YET ANOTHER SHORTWAVE
MOVES ACROSS THE NORTHWEST LIKELY TO DEVELOP ADDITIONAL
THUNDERSTORMS. THE SEVERE THREAT FOR MONDAY NIGHT IS A LITTLE LESS
CLEAR BUT SOME HEAVY RAINFALL IS POSSIBLE.

ANOTHER SHORTWAVE MOVES ACROSS THE NORTHERN PLAINS AND DIVES
SOUTHEAST ACROSS NORTHEAST IOWA. ANOTHER FRONTAL BOUNDARY WILL
ESTABLISH ITSELF ACROSS THE AREA TUESDAY FOR A CHANCE OF STORMS
ONCE AGAIN. FOR NOW I AM CARRYING CHANCE POPS ACROSS THE NORTH
MONDAY NIGHT AND NORTHEAST TUESDAY BUT THE FRONTAL BOUNDARY WILL
BE KEY TO THE AREAL EXTENT OF THE STORMS. THE LOCATION OF WHICH
WILL HOPEFULLY BECOME MORE CLEAR WITH TIME.

FOR THE REMAINDER OF THE EXTENDED A STRONG UPPER LEVEL RIDGE
BUILDS ACROSS THE ROCKIES PUTTING IOWA IN NORTHWEST FLOW ALOFT.
THIS WILL BRING SOME RELIEF FROM THE HEAT AND HUMIDITY
HOWEVER...TIMING OF ANY SHORTWAVES DROPPING DOWN ACROSS IOWA IN
THE NORTHWEST FLOW IS NEAR IMPOSSIBLE. FOR THIS REASON I DO NOT
HAVE POPS IN THE EXTENDED BUT THIS IS DUE TO A LACK OF CONFIDENCE
IN TIMING AND LOCATION AND NOT THINKING THAT SHORTWAVE WONT HAPPEN
ACROSS THE AREA DURING THIS TIME.

.AVIATION...23/06Z
ISSUED AT 1219 AM CDT SUN JUN 23 2013

MAIN CONCERNS FOR THE PERIOD WILL BE CONVECTION. SEVERAL ROUNDS
ARE EXPECTED WITH ONE YET PRIOR TO 12Z ACROSS THE WEST AND
POSSIBLY THE NORTH TAF SITES FOR KFOD AND KMCW AND TO A LESSER
EXTENT KALO. BY 16-17Z THE REMNANTS OF THE OLD OUTFLOWS...AN
APPROACHING TROUGH WITH BETTER SFC CONVERGENCE AND SIGNIFICANT
AFTERNOON INSTABILITY SHOULD RESULT IN WIDESPREAD CONVECTION
DURING THE AFTERNOON HOURS FROM 18Z NORTH TO ABOUT 02 TO 03Z IN
THE SOUTH ON THE 24TH. THIS MAY IMPACT OPERATIONS...TIMING SEEMS
TO FAVOR THE AFTERNOON AND EVENING HOURS AT KALO...KDSM...AND
KOTM. WITH MORE SIGNIFICANT CAPE AVAILABLE...SOME CONCERNS OF HIGH
WIND EVENT AND HEAVY RAINFALL COMBINED. WILL MONITOR THROUGH 12Z
AND SUNDAY AS WELL.
