AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
411 PM CDT THU JUN 5 2014

.SHORT TERM /TONIGHT/...
ISSUED AT 411 PM CDT THU JUN 5 2014

SCATTERED THUNDERSTORMS DEVELOPED OVER WESTERN IOWA THIS AFTERNOON
WHERE THE AIRMASS HAD DESTABILIZED COUPLED WITH FORCING ASSOCIATED
WITH A SHORTWAVE TROUGH MOVING THROUGH THE NORTHERN PLAINS.  THE
SHORTWAVE SHOULD CONTINUE TO MOVE EAST THIS EVENING SHIFTING IT/S
FORCING INTO AND THEN QUICKLY EAST OF CENTRAL IOWA. EXPECT THE
AIRMASS OVER CENTRAL IOWA TO DESTABILIZE ENOUGH TO SUPPORT SCATTERED
THUNDERSTORMS THIS EVENING MAINLY WEST AND NORTH. AS THE SHORTWAVE
MOVES EAST THIS EVENING AND AS THE AIRMASS STABILIZES...THE
THUNDERSTORMS SHOULD DISSIPATE.  THE LACK OF LOW LEVEL JET SUPPORT
SHOULD INHIBIT NOCTURNAL STORMS TONIGHT. WITH A WEAK HIGH PRESSURE
OVER THE AREA FRIDAY MORNING AND ABUNDANT BOUNDARY LAYER
MOISTURE...THERE SHOULD BE SOME PATCHY FOG EARLY. HOWEVER...NOT
ENOUGH CONFIDENCE TO MENTION IN PUBLIC FORECAST.

.LONG TERM /FRIDAY THROUGH THURSDAY/...
ISSUED AT 411 PM CDT THU JUN 5 2014

SOUTHERN GREAT LAKES HIGH PRESSURE WILL REMAIN THE DOMINANT
FEATURE TO IMPACT IOWA INTO FRIDAY. STILL POTENTIAL FOR A FEW
DIURNALLY DRIVEN AFTERNOON AFTERNOON THUNDERSTORMS. UPPER SHORT
WAVE WILL MOVE ACROSS SOUTHERN NEBRASKA AND KANSAS AND APPROACH
THE AREA FRIDAY NIGHT INTO SATURDAY MORNING. PRECIPITATION CHANCES
FRIDAY NIGHT INTO SATURDAY MORNING NOT REAL STRAIGHT FORWARD DUE
TO SEVERAL NEGATIVE FACTORS INTO CENTRAL IOWA. THETA-E ADVECTION
WILL COMMENCE AHEAD OF THE SHORTWAVE WITH PWATS ACROSS FAR
SOUTHERN IOWA APPROACHING 1.5 INCHES. RESIDUAL DRIER AIR FROM THE
DEPARTING HIGH SHOULD LINGER INTO CENTRAL AND EASTERN IOWA INTO
SATURDAY MORNING. IN ADDITION...THE LOW LEVEL JET WILL BE
SUPPRESSED WELL TO THE SOUTH AND MORE FOCUSED OVER TEXAS AND
OKLAHOMA AS THE UPPER FLOW IS PROGRESSIVELY ZONAL WITH SUB
TROPICAL HIGH MOVING NORTH INTO THE SRN CONUS AND AN UPPER LOW
MOVING ACROSS SOUTHERN CANADA. LARGE CANADIAN HIGH PRESSURE ALSO
BE MOVING SOUTHEAST ALONG THE LEE SIDE OF THE NORTHERN ROCKIES AND
INTO THE NORTHERN PLAINS. THERE IS A RIBBON OF INSTABILITY INTO
NORTHWEST IOWA EARLY SATURDAY AS A FRONTAL BOUNDARY AHEAD OF THE
HIGH MOVES INTO THAT AREA. HAVE KEPT THE LIKELY POPS FOR SATURDAY
THOUGH DIMINISHED THEM A BIT WITH THE OVERALL TRENDS FURTHERSOUTH
WITH THE SYSTEM. THE MAIN POPS MAY VERY WELL BE EARLY MORNING
PRECIPITATION OVER THE FAR SOUTH THEN POSSIBLE INITIATION ALONG
THE BOUNDARY DURING THE AFTERNOON.

THE SOUTHERN CANADA UPPER LOW WILL BE DICTATING THE UPPER FLOW AS
IT MOVES OVER HUDSON BAY THIS LATE SATURDAY AND INTO EARLY NEXT
WEEK. ANOTHER SHORT WAVE TROUGH WILL DROP SOUTHEAST AND INTO THE
MIDWEST ON MONDAY AND BRING ANOTHER CHANCE FOR THUNDERSTORMS. THE
UPPER FLOW WILL TRANSITION BACK TO ZONAL FOR THE END OF THE PERIOD
WITH A RETURN TO SUBTROPICAL HIGH TO THE SOUTH AND BROAD LOW
PRESSURE OVER CANADA.

.AVIATION...05/18Z
ISSUED AT 1216 PM CDT THU JUN 5 2014

AREA OF STRATUS OVER SOUTH CENTRAL IOWA EARLY SHOULD LIFT AND
BECOME A SCT-BKN DECK OF CU BY MID AFTERNOON. A SURFACE TROUGH
SHOULD BE OVER FAR WESTERN IOWA BY LATE THIS AFTERNOON ALONG WITH
AN AN INSTABILITY AXIS OVER WESTERN IA. THAT COUPLED WITH SOME
WEAK FORCING AND NO CAP SHOULD RESULT IN SCATTERED SHOWERS AND
THUNDERSTORMS. WHAT STORMS OCCUR SHOULD DISSIPATE QUICKLY THIS
EVENING AS AIRMASS STABILIZES. WEAK SURFACE RIDGE AND PLENTIFUL
BOUNDARY LAYER MOISTURE SHOULD RESULT IN AREAS OF FOG FRIDAY
MORNING. FORECASTED IFR VISIBILITIES WITH NO CEILINGS FOR NOW.
