SHORT TERM
 
(THIS EVENING THROUGH THURSDAY)  
ISSUED AT 234 PM CDT WED AUG 31 2016  
 
PATTERN OF THE LAST WEEK OR SO FINALLY STARTS TO TAKE A SHIFT  
TOWARDS DRIER DAYS LATER TODAY AS THE PLUME OF MOISTURE THAT HAS  
BEEN STREAMING OVER THE STATE STARTS TO GET SHIFTED TO THE SOUTH.  
HIGH PRESSURE FROM THE NORTHEAST AND ITS DRIER AIR IN THE LOWER  
LEVELS STARTING TO UNDERCUT WHAT REMAINS OF THE SHOWERS OVER THE  
AREA TODAY, WITH THE NORTHEASTERN COUNTIES DRYING OUT AND THE WEST  
AND SOUTH EXPECTED TO DRY OUT IN SHORT ORDER. COULD SEE MODERATE  
SHOWERS WEST AND EAST FOR ANOTHER HOUR OR TWO, BUT NO HAZARDOUS  
WEATHER IS ANTICIPATED. FOR TONIGHT, CLEARING SKIES AND WET GROUND  
COULD SPELL FOG IN LOW SPOTS, BUT SOUNDINGS ARE COMING IN PRETTY DRY  
OFF THE DECK AND MIGHT KEEP IT RELEGATED TO ALONG BODIES OF WATER  
AND SHALLOW. HAVE KEPT OUT OF THE FORECASTS FOR NOW BUT WILL NOTE  
TO INCOMING FORECASTERS. CLEAR SKIES AND ABUNDANT SUNSHINE GETS  
HIGH TEMPERATURES BACK TOWARD 80 FOR THURSDAY AFTERNOON. OVERNIGHT  
LOWS TONIGHT FALL INTO THE MIDDLE 50S WEST TO UPPER 50S EAST.  
   
LONG TERM
 
(THURSDAY NIGHT THROUGH WEDNESDAY)  
ISSUED AT 234 PM CDT WED AUG 31 2016  
 
A COOL AND DRY AIRMASS SETTLES IN TO THE MIDWEST FRIDAY AND SATURDAY  
AS WEAK EASTERLY WINDS SUSTAIN BELOW 10 MPH UNDERNEATH THE INVERTED  
RIDGE AXIS. SKIES ARE MOSTLY SUNNY YET BELOW NORMAL TEMPS FOR THIS  
TIME OF YEAR IN THE UPPER 70S TO LOWER 80S. OVERNIGHT LOWS ARE  
MAINLY IN THE LOW 60S. BY SATURDAY EVENING, UPPER RIDGE SHIFTS  
EASTWARD SOME HOWEVER HELD IN PLACE BY THE REMNANTS OF TROPICAL  
STORM HERMINE CENTERED OVER THE EAST COAST BY THIS TIME.  
MEANWHILE, UPPER TROUGH BEGINS TO DIG SOUTHEAST ACROSS THE WESTERN  
CONUS, DEVELOPING SCT STORMS NEAR A SFC FRONT OVER THE WESTERN HIGH  
PLAINS. THIS ACTIVITY MAY REACH NORTH CENTRAL AREAS OF KS LATE  
SATURDAY EVENING INTO SUNDAY, HOWEVER AM STILL EXPECTING THE DRY AIR  
TO HOLD ANY PRECIP FROM REACHING THE MAJORITY OF THE CWA. STORM  
CHANCES INCREASE BY SUNDAY AS THE FRONT APPROACHES FROM THE NORTH  
AND WEST. WEAK EMBEDDED WAVES ARE MAINLY FOCUSED BETWEEN GUIDANCE  
TOWARDS NEBRASKA, HOWEVER MAY IMPACT PORTIONS OF NORTHERN KS,  
ESPECIALLY ON TUESDAY AND WEDNESDAY WHEN THE FRONT REMAINS NEARLY  
STATIONARY OVER THIS AREA. SEVERE WEATHER WOULD NOT BE ANTICIPATED,  
HOWEVER PERIODS OF HEAVY RAINFALL MAY LEAD TO FLOODING CONCERNS ONCE  
AGAIN. DAYTIME HEATING AHEAD OF THE FRONT FROM LABOR DAY ONWARD  
AVERAGE HIGHS IN THE UPPER 80S WITH OVERNIGHT LOWS IN THE 60S.

VFR CONDITIONS ARE EXPECTED THROUGHOUT THE PERIOD. THERE IS A  
CHANCE FOR SOME FOG WHERE GROUNDS ARE STILL WET FROM SHOWERS, BUT  
FOR NOW THE BEST CHANCES LOOK TO BE SOUTH AND WEST OF THE TERMINALS.
