TONIGHT

AN UPPER LEVEL DISTURBANCE PUSHED THROUGH EASTERN NEBRASKA THIS
MORNING TRIGGERING A FEW SHOWERS AND THUNDERSTORMS.  HOWEVER DUE TO
WEAK CONVECTIVE PARAMETERS AND THE LACK OF ANY DECENT BOUNDARY IN
THE REGION THIS AREA OF PRECIP QUICKLY FIZZLED OUT. A FEW WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS HAVE POPPED UP ACROSS THE CWA
THIS AFTERNOON BUT SHOULD DIMINISH EARLY THIS EVENING AS THE
SHORTWAVE OVER THE AREA PUSHES FURTHER SOUTHEAST.  HIGH PRESSURE AND
DRIER AIR WILL THEN BUILD INTO THE REGION TONIGHT THROUGH SATURDAY
MORNING...KEEPING CONDITIONS DRY AS WE BEGIN THE WEEKEND.
TEMPERATURES WILL REMAIN SEASONABLE WITH HIGHS TOPPING OUT IN THE
LOW 80S AND UPPER 70S THIS AFTERNOON AND LOWS TONIGHT DIPPING INTO
THE LOW 60S AND UPPER 50S. SKIES WILL GRADUALLY CLEAR TONIGHT AND
NORTHERLY WINDS WILL BECOME LIGHT AND VARIABLE.

SATURDAY THROUGH MONDAY

NORTHWEST FLOW PREVAILS THROUGH THE PERIOD. TRYING TO DISCERN IF
THERE IS A VERY SUBTLE WAVE IN THE FLOW MAY BE A CHALLENGE FOR
SATURDAY AFTERNOON AS THE GFS/ECMWF/SREF ALL HINT AT ISOLATED
CONVECTION BY LATE MORNING AND EARLY AFTERNOON ACROSS SOUTHWEST
MINNESOTA THROUGH NORTHWEST IOWA. JUST NOT CONFIDENT THAT IT WOULD
BE ANYTHING MORE THAN MID CLOUDS...THUS WILL WAIT FOR ANOTHER
MODEL RUN TO SEE IF SOMETHING INDEED IS THERE TO ADD ANY MENTION
OF ISOLATED THUNDERSTORMS NORTH AND NORTHEAST OF OMAHA. TEMPS
SATURDAY SHOULD BE JUST SLIGHTLY BELOW NORMAL IN THE LOWER 80S.

OTHERWISE...A STRONG WAVE DOES MOVE OUT OF CENTRAL CANADA LATE
SATURDAY NIGHT THROUGH SUNDAY...AFFECTING AREAS MORESO TO OUR
EAST...BUT COULD JUST CLIP AREAS ALONG/EAST OF THE MISSOURI RIVER
WITH A SLIGHT CHANCE OF SHOWERS/THUNDERSTORMS...SIMILAR TO
PREVIOUS FORECAST DEPICTION. TEMPS BY SUNDAY SHOULD BE BACK TO
NORMAL WITH HIGHS IN THE MID TO UPPER 80S.

DRY AND SEASONABLE WEATHER FOR MONDAY WITH HIGHS AGAIN IN THE MID
TO UPPER 80S.

.LONG TERM...(MONDAY NIGHT THROUGH FRIDAY)
ISSUED AT 256 PM CDT FRI JUN 26 2015

THE NEXT NOTICEABLE WAVE TOPPING THE RIDGE ACROSS THE ROCKIES
MOVES INTO THE REGION TUESDAY THROUGH TUESDAY NIGHT WHEN THE NEXT
PRECIP CHANCES ENTER THE FORECAST. FORWARD SPEED OF THE WAVE IS IN
QUESTION AS MODELS ARE JUST SLIGHTLY DIFFERENT...BUT PRECIP
CHANCES COULD BE LINGERING WEDNESDAY MORNING AS THE WAVE DEPARTS
THE REGION. ANOTHER WAVE MOVES INTO THE REGION OUT OF CENTRAL
CANADA BEGINNING WEDNESDAY NIGHT...AND THROUGH THE AREA
THURSDAY...THEN EXITING THURSDAY NIGHT...BRING ONE MORE CHANCE FOR
STORMS. TEMPS SHOULD BE NEAR NORMAL TUESDAY...THEN JUST SLIGHTLY
BELOW NORMAL THROUGH THE REMAINDER OF THE WEEK.
