AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
636 AM CDT THU APR 17 2014

...UPDATED FOR 12Z AVIATION DISCUSSION...

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 257 AM CDT THU APR 17 2014

TODAY: CURRENT FRONTAL BOUNDARY CURRENTLY MOVING ACROSS SRN KS
WILL LEAD TO COOLER AIR FILTERING INTO THE REGION TODAY. THIS
COOLER AND SOMEWHAT DRIER SURFACE AIR WILL BE IN PLACE EARLY
TODAY...AS A SHORTWAVE CURRENTLY ALONG THE FRONT RANGE OF THE
ROCKIES MOVES EAST INTO THE SOUTHERN PLAINS. AS THIS SHORTWAVE
MOVES ACROSS...MID LEVEL MOISTURE WILL INCREASE OVER THE TOP OF
THE SHALLOW COOL AIR...WITH A 600-700H BAROCLINIC ZONE EXPECTED TO
DEVELOP ON THE NORTH SIDE OF THIS IMPULSE AS IT MOVES ACROSS OK.
SOME DIFFERENCES ON HOW MUCH MOISTURE WILL BE AVAILABLE AS THIS
BAROCLINIC ZONE MOVES ACROSS...AS SATURATION INCREASES IN THE MID
LAYERS...BUT THIS AIR WILL BE FIGHTING DRIER AIR IN THE LOW LEVELS
MOVING IN FROM THE NORTH. THIS DRIER AIR WILL PROBABLY LIMIT THE
NORTHWARD EXTENT OF ANY PRECIP THAT ACTUALLY REACHES THE
GROUND...BUT MID LEVEL LIFT AND SATURATION WILL LEAD TO A BAND OF
SHOWERS DEVELOPING AND MOVING ACROSS SRN KS BETWEEN 12-18Z. NOT
EXPECTING VERY HIGH QPF AMOUNTS...AS MOISTURE WILL BE
LIMITED...BUT PROBABLY MORE OF A HIGH POP...LOW QPF AMOUNT TYPE OF
EVENT WITH HIGHEST POPS SOUTH OF HIGHWAY 54/400. EXPECTING QPF
AMOUNTS MAINLY LESS THAN A QUARTER OF AN INCH...IN THE HEAVIEST
BAND.

FRI: A NICE SPRING DAY LOOKS ON TAP FOR FRI...AS WEAK RIDGING
MOVES ACROSS THE AREA. COULD SEE SOME GUSTY WINDS ACROSS CENTRAL
KS BY FRI AFTERNOON...AS LEE SIDE TROUGH BEGINS TO DEVELOP ALONG
THE FRONT RANGE OF THE ROCKIES. BUT SEASONAL TEMPS EXPECTED FOR
MOST AREAS.

KETCHAM

.LONG TERM...(SATURDAY THROUGH WEDNESDAY)
ISSUED AT 257 AM CDT THU APR 17 2014

SAT-SUN: THE NEXT SHORTWAVE LOOKS TO MOVE OUT OF THE SOUTHWEST US
INTO THE PLAINS FOR SAT INTO SUN. THIS SYSTEM IS A LITTLE DEEPER
AND FURTHER TO THE SOUTHWEST THAN TODAYS SYSTEM WHICH WILL ALLOW
MORE LOW LEVEL MOISTURE TO GET PULLED INTO THE PLAINS WITH THIS
SYSTEM...WHICH WILL LEAD TO SHOWER AND THUNDERSTORM CHANCES
BEGINNING TO INCREASE ON SATURDAY. MOISTURE TRANSPORT/ISENTROPIC
LIFT WILL LEAD TO SHOWERS AND THUNDERSTORMS INCREASING FIRST OVER
CENTRAL KS AHEAD OF THIS SYSTEM...WITH THIS SHOWER CHANCE
INCREASING FOR AREAS WEST OF INTERSTATE 135 BY SATURDAY AFTERNOON.
ELEVATED INSTABILITY AND SBCAPE VALUES...INCREASE ENOUGH FOR A
THUNDERSTORM CHANCE FOR SAT AFTERNOON. NOT ALOT OF SHEAR...SO
POSSIBLY ONLY A FEW STRONG STORMS.

THE CHANCE OF SHOWER/STORMS WILL INCREASE LATE SAT NIGHT INTO
SUN...AS THE LEFT FRONT QUAD OF AN UPPER LEVEL JET STREAK MOVES
ACROSS THE AREA...INCREASING LIFT ACROSS THE AREA...FOR A WIDESPREAD
SHOWER AND THUNDERSTORM CHANCE FOR SUN.  SHEAR AGAIN ISNT THAT
IMPRESSIVE...SO MORE OF A GARDEN VARIETY THUNDERSTORM CHANCE WITH
GOOD SOAKING RAINS.

MON-WED: WEAK RIDGING LOOKS TO MOVE ACROSS THE AREA...FOR THE
BEGINNING OF THE WEEK AS BOTH MEDIUM RANGE MODELS BRING A
SIGNIFICANT SHORTWAVE INTO THE SOUTHWEST US. THIS WILL BRING SW
FLOW OVER THE AREA...WITH WARMER TEMPERATURES FOR TUE INTO
WED...SO CONSENSUS IS TO TWEAK TEMPS UP FOR BOTH TUE INTO WED.
AFTER A COUPLE OF DRY DAYS...LOW LEVEL MOISTURE RETURN WILL
INCREASE FOR WED FOR A CHANCE OF SHOWERS AND THUNDERSTORMS FOR THE
MIDDLE OF THE WEEK.

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z FRIDAY MORNING)
ISSUED AT 636 AM CDT THU APR 17 2014

AN UPPER LEVEL SYSTEM IS APPROACHING THE AREA AND CAUSING A BAND
OF RAIN SHOWERS TO DEVELOP OVERNIGHT. THIS BAND IS NARROW...BUT IS
EXPECTED TO TRANSITION EASTWARD DURING THE DAYTIME HOURS. MAIN
TERMINALS IMPACTED ARE KHUT/KICT/KCNU. RAIN SHOWERS WILL BE
LIMITED...AND TIMING IS STILL SOMEWHAT QUESTIONABLE. HAVE BEST
GUESS IN TEMPO GROUP FOR WHEN RAIN SHOWERS WILL MOVE THROUGH THE
AREA. THINK CEILINGS AND VISIBILITIES WILL REMAIN VFR...BUT IF THEY
DO DROP...IT WILL BE INTO THE MVFR CATEGORY...LONG TERM IFR IS NOT
ANTICIPATED. RAIN CHANCES WILL DIMINISH FOR KHUT/KICT BY LATE
AFTERNOON AND BY KCNU BY EVENING. WINDS WILL BE NORTHERLY AND
EVENTUALLY SOUTHEASTERLY AND SOUTHERLY AS HIGH PRESSURE MOVES
EASTWARD.

.FIRE WEATHER...
ISSUED AT 257 AM CDT THU APR 17 2014

WARMING TEMPERATURES FRIDAY INTO SATURDAY...WITH VERY HIGH GRASSLAND
FIRE DANGER FORECAST IN CENTRAL AND SOUTH CENTRAL KS.
