AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
256 PM CDT TUE JUL 22 2014

.SYNOPSIS...
ISSUED AT 255 PM CDT TUE JUL 22 2014

BROAD UPPER RIDGING CURRENTLY ENCOMPASSES THE SOUTHERN ROCKIES
INTO THE CENTRAL PLAINS. ONE SHORTWAVE TROUGH IS TRACKING ACROSS
THE NORTHERN GREAT LAKES WITH ANOTHER...MUCH WEAKER...IMPULSE
SLIDING OVER SOUTHERN SD. AT THE SURFACE...A WEAK COLD FRONT
STRETCHES FROM EASTERN IA...TO NEAR THE KS-NEBRASKA BORDER.

&&

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 255 PM CDT TUE JUL 22 2014

DUE TO CAPPING AND LACK OF UPPER SUPPORT...CONVECTION ALONG THE
FRONT HAS BEE VERY LIMITED. STILL FEEL THERE WILL BE A SMALL
CHANCE TONIGHT OVER MAINLY EASTERN KS WHICH WILL BE FURTHER AWAY
FROM THE INFLUENCE OF THE UPPER RIDGE AND IN AN AREA OF UPPER
DIFFLUENCE. THE FRONT WILL WASH OUT AS IT CONTINUES TO PUSH SOUTH
ON WED WITH RETURN FLOW COMMENCING ACROSS THE HIGH PLAINS BY WED
AFTERNOON. DUE TO LACK OF CONVERGENCE ALONG THE FRONT...NOT
EXPECTING MUCH IN THE WAY OF STORMS ALONG IT ON WED. THERE IS
DECENT AGREEMENT BETWEEN THE GFS AND NAM THAT SOME MONSOONAL
ENERGY WILL CIRCULATE AROUND THE HIGH AND WILL SLIDE OVER NEBRASKA
ON THU AND INTO THE MID MISSISSIPPI VALLEY BY THU EVENING. THIS
SHOULD KEEP THE BULK OF THE PRECIP NORTH OF THE FORECAST AREA.

THE UPPER PATTERN IS EXPECTED TO FLATTEN OUT FOR FRI AS A POWERFUL
SHORTWAVE TROUGH TRACKS ACROSS SOUTHERN SASKATCHEWAN AND MANITOBA.
THIS WILL RESULT IN A WEAK SURFACE TROUGH MOVING INTO KS WITH
VERY HOT TEMPS EXPECTED ALONG AND JUST AHEAD OF THIS FEATURE.

TEMPS ON WED AND THU WILL BE CLOSER TO SEASONAL AVERAGES AS THE
FRONT MOVES THROUGH. LOCATIONS ALONG AND WEST OF I-135 WILL HAVE A
CHANCE AT THE CENTURY MARK ON FRI WITH SW WINDS AND DECENT MIXING.

.LONG TERM...(SATURDAY THROUGH TUESDAY)
ISSUED AT 255 PM CDT TUE JUL 22 2014

THE GFS CONTINUES TO BE MORE ROBUST IN TRACKING THE SHORTWAVE
ENERGY OUT OF SOUTHERN CANADA AND ACROSS THE NORTHERN MISSISSIPPI
VALLEY BY SUN MORNING. MEANWHILE...THE ECMWF ISN`T AS DEEP WITH
THE TROUGH AND KEEPS MUCH OF THE UPPER ENERGY FURTHER NORTH
COMPARED TO THE GFS. THE GOOD NEWS IS THAT BOTH AGREE ON A
UNSEASONABLY SHARP TROUGH EXTENDING FROM THE GREAT LAKES DOWN
THROUGH THE TENNESSEE VALLEY BY MON MORNING. THIS WILL RESULT IN
ANOTHER COLD FRONT MAKING ITS WAY ACROSS THE PLAINS TO START THE
WORK WEEK. IF THE GFS VERIFIES IT WOULD BE SEVERAL DEGREES COOLER
THAN WHAT THE ECMWF IS ADVERTISING. WILL CONTINUE WITH SOME SMALL
PRECIP CHANCES AS THE FRONT MAKES ITS WAY SOUTH ON SUN INTO SUN
NIGHT BUT CONFIDENCE IS HIGH WE ARE NOT LOOKING AT A WIDESPREAD
PRECIP EVENT.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1251 PM CDT TUE JUL 22 2014

THE COLD FRONT THAT WILL MOVE THROUGH THE REGION TONIGHT WAS
STILL IN NEBRASKA AT 1730Z. SATELLITE SHOWING SOME UNDULAR BORE
TYPE ACTION ACROSS THE EASTERN HALF OF KANSAS AND SOUTHEAST
NEBRASKA. THIS WILL RESULT IN SOME PRETTY GOOD TURBULENCE IN THESE
AREAS.

THUNDERSTORMS TONIGHT WILL DEVELOP AND MOVE SOUTH ACROSS EASTERN
KANSAS. BY 12Z WEDNESDAY...THEY SHOULD BE NEAR KCNU. THE STORMS
SHOULD REMAIN EAST OF INTERSTATE 135.

CONFIDENCE IS VERY LOW THAT FOG OR IFR CIGS WILL DEVELOP AGAIN
TOWARD MORNING. THIS CANNOT BE RULED OUT AT THIS TIME...BUT
CHANCES ARE SMALL ENOUGH THE WE OMITTED IT FROM THE TAFS AT THIS TIME.
