AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
313 PM CDT WED JUL 7 2010

.SHORT TERM /TONIGHT/...
MAIN CONCERN FOR TONIGHT/S FORECAST IS THE SLOW MOVING COLD FRONT
CURRENTLY STRETCHING FROM ESTHERVILLE TO STORM LAKE.  THIS FRONT WILL
TAKE ALL NIGHT TO WORK THROUGH THE CWA AND CURRENT QPE IS 2-3 INCHES
PER HOUR.  THAT WILL BE A LOT OF WATER ONCE AGAIN OVER THE CWA.
CURRENT FF.A LOOKS TO BE GOOD POSITION WISE BUT I WILL NEED TO
EXTEND THE TIME OF THE WATCH OVER THE FAR SOUTHEAST DUE TO THE SLOW
MOVING NATURE OF THE FRONT.  FLASH FLOOD GUIDANCE FOR THE NW IS
CONSIDERABLY HIGHER THAN THE REST OF THE CWA AND WHILE WE WILL BE
PUSHING THOSE LIMITS...WE WILL FOR SURE BE OVER THE 1-2 INCH
GUIDANCE AMOUNTS ELSEWHERE.  THE FRONT WILL BE IN FAR SE IA BY DAY
BREAK AND WHILE SOME LINGERING SHOWERS MAY OCCUR BEHIND THE FRONT
THE HEAVY RAIN WILL BE DONE.  AHEAD OF THE FRONT...THERE WILL BE
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS AND THOSE WILL NEED TO
BE WATCHED FOR HEAVY RAIN POTENTIAL BUT THEY APPEAR TO BE MORE
TRANSITORY IN NATURE AND ARE WEAKER THAN THOSE SHOWERS AND STORMS
ALONG THE FRONT.

.LONG TERM /THURSDAY THROUGH WEDNESDAY/...A COUPLE OF CONCERNS WITH
THE EXTENDED PERIOD.  FIRST IS WITH LINGERING POPS ACROSS THE
SOUTHEAST THROUGH THURSDAY MORNING BEFORE THE COLD FRONT FINALLY
CLEARS THE STATE. NEXT ISSUE IS WITH TROUGH OF LOW PRESSURE ENTERING
THE REGION BY SUNDAY INTO MONDAY. MODELS ARE NOT IN GOOD AGREEMENT
WITH PLACEMENT AND TIMING OF QPF...WITH GFS SLIGHTLY FASTER THAN THE
ECMWF.

THURSDAY...COLD FRONT LOOKS TO CLEAR THE SOUTHEAST BY 18Z THURSDAY
AS IT LOOKS TO FINALLY GET SOME PUSH BY THE SURFACE HIGH PRESSURE.
NAM SEEMS TO BE SLIGHTLY FASTER THAN THE GFS AND THINKING WITH HOW
SLOW THIS COLD HAS MOVED TODAY LEANED TOWARDS THE GFS ON THURSDAY.
FRONTOGENETICAL FORCING CONTINUES THROUGH THE MORNING HOURS THURSDAY
AND PW VALUES STILL RANGE AROUND 2 INCHES. WARM CLOUD TOPS RANGE UP
TO 14 KFT AND BUFR SOUNDINGS REMAIN DEEPLY SATURATED NEAR OTM
THROUGH 15Z. HEAVY RAIN THREAT MAIN CONCERN OVER THE SOUTHEAST
DURING THE MID MORNING HOURS.

FRIDAY AND SATURDAY...SURFACE HIGH PRESSURE AND UPPER LEVEL RIDGE
BUILD INTO THE STATE AND PROVIDE A MUCH DRIER AIR MASS. DEW POINTS
LOOK TO DROP AT LEAST 15 DEGREES FROM TODAY/S AIR MASS AND WILL
ALLOW FOR A COUPLE OF DRY DAYS.

SUNDAY THROUGH WEDNESDAY...MODELS ARE NOT IN GOOD AGREEMENT WITH
UPPER LEVEL TROUGH OF LOW PRESSURE AND ASSOCIATED COLD FRONT TO
AFFECT THE CWA EARLY NEXT WEEK.  KEPT WITH MENTION OF POPS SUNDAY
NIGHT INTO TUESDAY WITH THE POTENTIAL OF COLD FRONT STALLING OUT
ACROSS THE STATE AGAIN.  UPPER LOW APPEARS TO BE FAIRLY STRONG WITH
DECENT DYNAMICS AVAILABLE...WITH GOOD CAPE VALUES AND SHEAR
AVAILABLE ON SUNDAY AFTERNOON ACROSS THE WEST. HIGH PRESSURE WILL
BUILD INTO THE REGION BY THE MIDDLE OF NEXT WEEK.

&&

.AVIATION...
07/18Z...WIDESPREAD MVFR COND ARE EXPECTED AS HEAVY RAIN PRODUCING
SHOWERS REDEVELOP OVER THE TAF LOCATIONS THIS AFTERNOON AND EVENING.
A COLD FRONT WILL SLOWLY PUSH ACROSS THE TAF LOCATIONS AND BRING AN
END TO THE RAIN THOUGH FOG MAY CONTINUE TO LIMIT VSBYS.  THE COLD
FRONT SHOULD BE THROUGH KFOD AROUND 03Z...KDSM AROUND 08Z AND KOTM
TOWARDS DAYBREAK.
