.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 349 PM CDT FRI MAY 29 2015

SHOWERS LINGERING BEHIND THE COLD FRONT WILL MOVE OUT STEADILY
DURING THE EVENING HOURS AND CLEARING WILL BEGIN FROM THE NORTH. A
FEW STORMS TO THE START OF THE EVENING ARE LIKELY FAR SOUTHEAST
TOWARD SLB AND IDA GROVE IN NORTHWEST IA. THE CLEARING WILL PROGRESS
SOUTH/SOUTHEAST OVER THE AREA DURING THE NIGHT. A STIFF NORTHERLY
BREEZE WILL CONTINUE INTO THE EVENING ESPECIALLY FAR
SOUTHEAST...THEN WINDS SHOULD SETTLE DOWN TO TEN MPH OR SO LATE
TONIGHT...10 TO 15 SOUTHEAST. LOW TEMPERATURES STILL LOOK LIKE
40S...40 NORTHWEST TO UPPER 40S SOUTHEAST.

SATURDAY STILL LOOKS GENERALLY SUNNY WITH JUST A LITTLE LINGERING
CLOUDINESS EARLY SOUTHEAST. A STEADY BUT TOLERABLE NORTHEAST BREEZE
WILL PREVAIL WITH THE SURFACE HIGH CENTER MOVING WELL TO THE
NORTH/NORTHEAST OF THE AREA. TEMPERATURES SATURDAY STILL LOOK LIKE
60S HIGHS.


.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 349 PM CDT FRI MAY 29 2015

THE SURFACE RIDGE CONTINUES TO PUSH OFF TO THE EAST ON SATURDAY
NIGHT...WITH WINDS SLOWLY TRANSITIONING TO SOUTHEASTERLY BEHIND THE
EXITING HIGH. IT WILL BE ANOTHER COOL NIGHT WITH LOWS IN THE LOWER
TO MID 40S. ON SUNDAY MIDLEVEL WARM AIR ADVECTION/ISENTROPIC LIFT
OVERSPREAD THE AREA AS A SHORTWAVE OUT OF THE NORTHERN ROCKIES
SLIDES THROUGH THE NORTHERN PLAINS. THIS WILL BRING A SMALL CHANCE
OF SHOWERS AND ISOLATED THUNDERSTORMS FOR SUNDAY INTO SUNDAY NIGHT.
TEMPERATURES FOR SUNDAY WILL REMAIN JUST BELOW NORMAL WITH HIGHS IN
THE MID 60S TO LOWER 70S.

BY NEXT WEEK AN UPPER LEVEL RIDGE BUILDS ACROSS THE CENTRAL CONUS.
THIS WILL RESULT IN TEMPERATURES WARMING BACK ABOVE NORMAL FOR THE
WEEK...WITH HIGHS GENERALLY 80S AND LOWS IN THE 60S THROUGH NEXT
FRIDAY. IT DOES APPEAR TO BE SOMEWHAT UNSETTLED THROUGH THE WEEK
HOWEVER AS A SERIES OF SHORTWAVES SLIDE THROUGH THE RIDGE AND AFFECT
OUR AREA. CONFIDENCE IN PRECIPITATION CHANCES REMAIN LOW WITH MODEL
DIFFERENCES IN THE HANDLING OF THESE DISTURBANCES. CHANCES FOR
SEVERE WEATHER THROUGH THE EXTENDED REMAIN ON THE LOW SIDE WITH A
WEAK MID/UPPER LEVEL FLOW RESIDING ACROSS THE CENTRAL PORTION OF THE
COUNTRY DURING THAT TIME FRAME.
