AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1234 PM CDT THU MAY 8 2014

.SHORT TERM /TODAY/...
ISSUED AT 349 AM CDT THU MAY 8 2014

AN ACTIVE DAY ON TAP WITH COLD FRONT ENTERING THE CWA AT PRESENT.
SECOND LOW WILL MOVE NORTHEAST ALONG THE FRONT DAY AND MAKE FOR AN
ACTIVE DAY.  INCEPTION TIME OF THE AFTERNOON ROUND A LITTLE UNCLEAR
WITH THE CURRENT CONVECTION MESSING UP THE WORKS A BIT...BUT EXPECT
TO SEE ENOUGH INSTABILITY BY MID DAY TO GET IT GOING.  CHANGED
WORDING TO SEVERE WORDING AFTER 17Z AND CARRIED THAT THROUGH THE
AFTERNOON.  MENTIONED HAIL AND WIND IN THE TEXT.  DECENT CAPE
AVAILABLE WITH SOUNDINGS SHOWING 2500 TO 30OO J/KG AND DCAPE FAIRLY
STOUT AROUND 700 INDICATED.  THE DCAPE IS LOWER THAN LAST NIGHTS
1700...BUT PLENTY TO GIVE SEVERE WINDS.  DRY SLOT WILL PUSH INTO THE
WEST AND WILL LIKELY END UP WITH THE HIGHEST TEMPS IN THOSE AREAS
WITH CONVECTION OFF TO THE EAST.

.LONG TERM /TONIGHT THROUGH WEDNESDAY/...
ISSUED AT 349 AM CDT THU MAY 8 2014

THE AFOREMENTIONED COLD FRONT PUSHES EAST DURING THIS EVENING AND
BY MID TO LATE EVENING THE THUNDERSTORM THREAT LEAVES TO THE EAST
WITH THE FRONT. IT IS POSSIBLE FOR LINGERING SHOWERS OR AN
ISOLATED STORM INTO THE OVERNIGHT BUT MOST OF THE ACTIVITY WILL
MOVE INTO ILLINOIS.

ON FRIDAY WE ARE IN BETWEEN SYSTEMS WITH A WEAK SURFACE HIGH AND A
SHORT WAVE RIDGE IN PLACE. DRY CONDITIONS WITH COOL TEMPS ARE IN
STORE.

FOR SATURDAY ANOTHER SHORTWAVE PUSHES INTO THE NORTHERN PLAINS AS
A SURFACE LOW TAKES SHAPE OVER THE CENTRAL PLAINS. EVENTUALLY A
FRONTAL BOUNDARY SETS UP AND LIFTS INTO THE REGION FOR SUNDAY. ON
SATURDAY WE SHOULD SEE SCATTERED SHOWERS AND AT LEAST ISOLATED
STORMS ON SATURDAY. AT THIS POINT I AM NOT LOOKING AT MUCH OF A
SEVERE POTENTIAL...UNLESS THAT FRONT TAKES SHAPE QUICKER AND
SHIFTS INTO THE VICINITY. I EXPECT THE FRONT TO BE IN OR NEAR
SOUTHERN IOWA FOR SUNDAY THUS THUNDERSTORMS WILL BE ON THE
INCREASE ALONG WITH THE POTENTIAL FOR SEVERE STORMS.

FOR EARLY NEXT WEEK THE ACTIVE PATTERN CONTINUES WITH A LONG WAVE
TROUGH SETTING UP OVER THE LEE SIDE OF THE ROCKIES THEN SHIFTING
INTO THE MIDWEST. THIS WILL CONTINUE TO BRING PERIODS OF SHOWERS
AND STORMS THOUGH THE SEVERE THREAT APPEARS MINIMAL AT THIS TIME.
THERE IS SOME QUESTION AS TO HOW THE SURFACE LOW WILL EVOLVE WHICH
WILL IMPACT THE POTENTIAL FOR SEVERE STORMS. THIS WILL BE BETTER
DETERMINED LATER.

&&

.AVIATION...08/18Z
ISSUED AT 1230 PM CDT THU MAY 8 2014

LOW PRESSURE SYSTEM WILL LIFT NE INTO NORTHWESTERN IOWA THROUGH
THE DAY...BRING TSRA AHEAD OF LOW NEAR BOUNDARY. WINDS WILL BE
GUSTY AHEAD OF BOUNDARY WITH TSRA ANTICIPATED TO AFFECT SITES IN
THE LATE AFTERNOON AND EARLY EVENING. TSRA COULD BRING HEAVY RAIN
AND WIND GUSTS TO SITES ALONG WITH MVFR OR LOWER CONDITIONS.
BEHIND BOUNDARY WINDS WILL REMAIN STRONG AS LOW CONTINUES TO LIFT
NE. WINDS WILL BECOME WESTERLY NEAR 06Z...WITH GUSTS EXPECTED
FRIDAY AFTERNOON.
