WEATHER SUMMARY FOR IOWA
NATIONAL WEATHER SERVICE DES MOINES IA
500 AM CDT WED APR 16 2014

THERE WAS MAINLY MID AND HIGH LEVEL CLOUD COVER ACROSS IOWA DURING
THE OVERNIGHT HOURS.  SURFACE LOW PRESSURE OVER SOUTH DAKOTA WAS
INTENSIFYING THIS MORNING CREATING A STRONG PRESSURE GRADIENT ACROSS
THE STATE.  THIS WAS EVIDENT AS SOUTHERLY FLOW INCREASED ACROSS THE
WESTERN HALF OF THE STATE.  AT 5 AM THE WIND WAS SOUTHERLY ACROSS
ALL OF IOWA BUT WINDS ACROSS THE WEST HALF OF THE STATE WERE ALREADY
AT 20 TO 30 MPH WHILE OVER THE EAST THEY WERE 15 TO 20 MPH AND NOT
AS GUSTY.

THE STRONG SURFACE LOW PRESSURE SYSTEM OVER SOUTH DAKOTA WILL GET
PUSHED EAST TODAY BY AN UPPER LEVEL SYSTEM.  STRONG SOUTHERLY FLOW
WILL DEVELOP AHEAD OF THE LOW AND THE COMBINATION OF THE WIND AND
DRIER AIR MOVING IN WILL CREATE AN ELEVATED FIRE DANGER OVER MUCH OF
THE UPPER MIDWEST AND THE ISSUANCE OF A RED FLAG WARNING FOR EXTREME
FIRE DANGER OVER PORTIONS OF SOUTHERN IOWA AND LOCATIONS SOUTH.  WIND
ADVISORIES HAVE BEEN ISSUED FOR MUCH OF THE SAME AREA AS THE RED
FLAG WARNING BUT WILL EXTEND A LITTLE FURTHER TO THE NORTHEAST.  AS
THE UPPER LEVEL SYSTEM PUSHES EAST IT WILL MOVE THE SURFACE LOW EAST
AND DRAG A COLD FRONT ACROSS THE AREA BRINGING A CHANCE FOR RAIN...
MAINLY TO FAR NORTHERN IOWA AND LOCATIONS NORTH.

HIGH PRESSURE WILL THEN BUILD IN FOR THE REST OF THE WEEK BRINING
COOLER TEMPS IN FOR THURSDAY AND FRIDAY.  THERE IS A SMALL CHANCE
FOR PRECIPITATION THURSDAY NIGHT AS A WEAK DISTURBANCE SLIDES
QUICKLY TO THE SOUTHEAST.  THE NEXT BEST CHANCE FOR SHOWERS AND A
FEW THUNDERSTORMS WILL COME LATE SATURDAY THROUGH SUNDAY NIGHT.
HIGHS WILL WARM BY SUNDAY INTO THE UPPER 50S TO UPPER 60S ACROSS THE
REGION.
