AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1249 PM CDT SUN JUN 7 2015

.UPDATE...
ISSUED AT 1246 PM CDT SUN JUN 7 2015

HAVE ADDED LOW POPS ACROSS FAR NORTHERN IOWA THIS AFTERNOON AS
HIGH BASED SHOWERS HAVE DEVELOPED IN RESPONSE TO A SHORT WAVE
MOVING E/NE OUT OF NEBRASKA. LOW LEVELS WILL BE RELATIVELY DRY
BELOW WITH GOOD EVAPORATION OCCURRING BELOW CLOUD LEVEL.
STILL...SOME CHANCE FOR VERY LIGHT MEASURABLE PRECIPITATION.
SURFACE BOUNDARY STILL LINGERING OVER FAR SOUTHEAST IOWA. SHOULD
HAVE A FEW THUNDERSTORMS DEVELOP ACROSS THIS AREA THIS AFTERNOON.
UNIDIRECTIONAL WIND PROFILES WILL BE SUPPORTIVE FOR THE POTENTIAL
FOR DAMAGING WINDS. IN ADDITION...STEEPENING MID LEVEL LAPSE RATES
AND FATTENING CAPES WILL BE SUPPORTIVE FOR GOOD VERTICAL PARCEL
ACCELERATIONS AND UPDRAFT STRENGTHS FOR LARGE HAIL DEVELOPMENT.
THE TORNADIC THREAT IS NEARLY NON EXISTENT WITH 0-1 KM ESRH VALUES
AT 50 M2/S2 OR LESS AND LCL HEIGHTS INCREASING TO 1200M. MUCH OF
CENTRAL IOWA INCLUDING THE DES MOINES METRO AND THE I-80 CORRIDOR
NORTH TO HIGHWAY 3 ARE EXPECTED TO REMAIN DRY.

&&

.SHORT TERM /TODAY/...
ISSUED AT 342 AM CDT SUN JUN 7 2015

FOR THIS MORNING...AN MCS WILL EXIT THE STATE BY MID MORNING AND
BRING AN END TO THE PRECIP FOR A SHORT TIME TODAY. A COLD FRONT
WILL PUSH ACROSS THE STATE TODAY AND REDEVELOPMENT OF
THUNDERSTORMS WILL OCCUR DURING PEAK HEATING HOWEVER BY THAT TIME
THE FRONT LOOKS TO BE SUFFICIENTLY FAR ENOUGH SOUTH THAT A FAIR
PORTION OF THE FORECAST AREA SHOULD NOT SEE STORMS TODAY.
THUNDERSTORM ACTIVITY SHOULD BE RELEGATED TO THE SOUTH AND EAST.
HAVING SAID THAT HOWEVER...WE REMAIN MODESTLY UNSTABLE AND SHEAR
REMAINS SUFFICIENT FOR ADDITIONAL STRONG TO SEVERE STORMS THIS
AFTERNOON ACROSS THE SOUTH AND EASTERN THIRD OR SO OF CENTRAL
IOWA. WHILE THE PRIMARY CONCERN THIS AFTERNOON WOULD BE DAMAGING
WIND...LOW LEVEL SHEAR IS A BIT CONCERNING LATE THIS AFTERNOON
FOR AT LEAST AN ISOLATED TORNADO THREAT.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
ISSUED AT 342 AM CDT SUN JUN 7 2015

COLD FRONT GRADUALLY SHIFTS OUT OF THE STATE TONIGHT AND ANY
CONVECTION THAT RE-DEVELOPED ALONG THE FRONT DURING PEAK HEATING
WILL SHIFT SOUTH AND EAST WITHIN THE FIRST COUPLE HOURS OF THE
EVENING. ALOFT...A SHORTWAVE WILL SHIFT EAST ACROSS THE NORTHERN
HIGH PLAINS AND UPPER MIDWEST. THE FEATURE WILL BRING SOME SHOWERS
AND THUNDERSTORMS TO CENTRAL AND POSSIBLY SOUTHERN MINNESOTA BUT
THESE SHOULD NORTH OF IOWA. I AM NOT ANTICIPATING ANY
PRECIPITATION FROM THE SHORTWAVE TONIGHT.

UPPER LEVEL RIDGING BUILDS INTO THE ROCKIES FOR THE FIRST PART OF
THE WORKWEEK BUT A THERMAL RIDGE WILL SET UP AND SHIFT INTO THE
UPPER MIDWEST. THIS WILL BRING SOME VERY WARM TEMPERATURES TO THE
STATE FOR THE COMING WEEK WITH THE WARMEST DAY BEING TUESDAY.

FOR WEDNESDAY A LOW OVER CANADA WILL SHIFT EAST DRAGGING A SURFACE
COLD FRONT ACROSS THE NORTHERN PLAINS AND UPPER MIDWEST.
TEMPERATURES WILL BE SEVERAL DEGREES COOLER FOR
WEDNESDAY/THURSDAY. PRECIP ASSOCIATED WITH THE FRONT WILL
GENERALLY GRAZE IOWA LATE TUESDAY NIGHT ACROSS THE FAR NORTH THEN
SOUTH AND EAST ON WEDNESDAY.

WEDNESDAY NIGHT AND THURSDAY MODELS SUGGEST A SHORTWAVE MOVING
ACROSS THE WESTERN U.S. INCREASING PRECIP CHANCES DURING THIS
PERIOD. MODELS SUGGEST THAT THE FRONT FROM THE WEDNESDAY SYSTEM
WILL HANG UP SOMEWHERE ACROSS THE UPPER MIDWEST.  I DO NOT HAVE
HIGH CONFIDENCE IN POPS DURING THIS PERIOD HOWEVER UNTIL A MORE
POTENT WAVE COMES THURSDAY INTO FRIDAY. THIS SYSTEM WILL DIG INTO
THE SOUTHWEST U.S. THURSDAY THEN EJECT TOWARDS THE UPPER MIDWEST
AND PUSH A SURFACE LOW TOWARDS IOWA. THIS WILL THEN PUSH THE
FRONTAL BOUNDARY NORTH AS A WARM FRONT...THOUGH LOCATION OF THIS
BOUNDARY IS A LITTLE NEBULOUS AT THIS POINT BUT IMPORTANT TO WHERE
CONVECTION WILL FIRE. CONVECTION WILL DEVELOP ALONG THE BOUNDARY
AND MODELS DO INCREASE THE INSTABILITY AND SHEAR ALONG THE
BOUNDARY SO STORMS WILL LIKELY BE STRONG OR SEVERE THURSDAY AND
FRIDAY BUT JUST WHERE IS IN QUESTION AT THIS POINT. THE GFS THINGS
A LITTLE FURTHER NORTH...INTO MINNESOTA WHILE THE CANADIAN AND
EURO HINTS MORE AT NORTHERN IOWA. WE REMAIN IN A BROAD
SOUTHWESTERLY FLOW THROUGH NEXT WEEKEND AND IT LOOKS TO REMAIN AN
ACTIVE PATTERN THROUGH LATE IN THE EXTENDED AND BEYOND.

&&

.AVIATION...07/18Z
ISSUED AT 1246 PM CDT SUN JUN 7 2015

A FEW AREAS OF MVFR CIGS MOVING SOUTH ACROSS CENTRAL IOWA EARLY
THIS AFTERNOON. THE CIGS WILL GRADUALLY RISE ABOVE 3 KFT THE NEXT
FEW HOURS. A FEW THUNDERSTORMS POSSIBLE MID TO LATE AFTERNOON
VICINITY OF KOTM. VFR CONDITIONS EXPECTED OVERNIGHT. BREEZY
NORTHWEST WINDS DEVELOPING BY MID MONDAY MORNING.
