AREA FORECAST DISCUSSION

...UPDATED THE SHORT TERM DISCUSSION...

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 355 PM CDT MON JUL 29 2013

THE BIGGEST CHALLENGE IN THIS FORECAST IS WHEN AND HOW STRONG WILL
SEVERE STORMS BE THIS EVENING.  THE WARM FRONT HAS BEEN LIFTING
NORTH EARLY THIS AFTERNOON, ALLOWING SKIES TO CLEAR AND FOR THE
SURFACE TO WARM UP AND DESTABILIZE.  THAT WARM UP HAS BEEN STARTING
IN OUR SOUTHWEST COUNTIES NEAR HUGOTON FIRST, AND SLOWLY SPREADING
TO THE NORTH AND EAST AS THE AFTERNOON HAS PROGRESSED.  DEW POINTS
ARE HIGHER IN EASTERN CWA, IN THE 70 DEGREE RANGE, WITH UPPER 50S IN
OUR WESTERN KANSAS COUNTIES.  SO, FORECAST MUCAPES FROM THE NAM AND
HRRR MODELS WILL LIKELY REACH THE 3000 TO 4000 J/KG LEVELS BY THE
22-00Z TIME FRAME.  CAPES WILL BE LARGE ENOUGH FOR STORMS TO PRODUCE
PERHAPS GOLF BALL SIZE HAIL AND WIND DOWNBURSTS TO 70-80MPH.  HEAVY
DOWN POURS ARE POSSIBLE FROM A FEW STORMS, AS THE 12Z DDC SOUNDING
SHOWED 1.66 FOR PWATS.  SPC HAS JUST ISSUED AN MCD FOR A POSSIBLE
WATCH SOON, MAINLY OVER OUR SOUTH CENTRAL AND SOUTHEASTERN FORECAST
AREA.  I AGREE WITH THIS POTENTIAL WATCH AND WILL FOLLOW SPC'S LEAD
ON THIS. POPS WILL BE VERY HIGH IN THE EASTERN COUNTIES, UP AROUND
90 PERCENT THROUGH ALMOST MIDNIGHT, AND PRECIP CHANCES WILL DIMINISH
TO THE WEST,  DDC WILL HAVE LIKELY POPS, GARDEN CITY 36 PERCENT
CHANCES, AND LOWER CHANCES WEST OF GARDEN.  BY 12Z TUESDAY MORNING,
PERCENT RAIN CHANCES WILL DIMINISH TO 20 PERCENT.

MINIMUM TEMPERATURES TONIGHT WILL FALL INTO THE MID 60S FROM
SYRACUSE TO SCOTT CITY, THE UPPER 60S FROM LARNED TO DODGE CITY TO
LIBERAL, AND TO ONLY AROUND 70 DEGREES IN THE MEDICINE LODGE AREA.
TUESDAY SHOULD BE PARTLY TO MOSTLY CLOUDY FOR MOST OF THE DAY, WITH
A LEE SIDE TROUGH ADVANCING INTO FAR WESTERN KANSAS LATE IN THE DAY
TUESDAY. THIS TROUGH COULD BE A CONVERGENCE ZONE FOR A FEW
THUNDERSTORMS TO INITIATE ALONG AFTER 22Z OR SO.  JUST 20 PERCENT
CHANCES FOR RAIN SEEM APPROPRIATE, AS THERE WILL NOT BE AN UPPER
SYSTEM WORKING THROUGH WESTERN KANSAS TUESDAY AFTERNOON.  HIGHS FOR
TUESDAY WILL REACH THE MIDDLE 80S IN THE HAYS AND WAKEENEY AREAS,
AND NEAR 90F DEGREES IN THE LIBERAL AND ELKHART AREAS.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 351 PM CDT MON JUL 29 2013

BY TUESDAY NIGHT AND WEDNESDAY, AN UPPER LEVEL TROUGH WILL BE SITUATED
OFF THE WEST COAST, WITH A FLAT UPPER LEVEL RIDGE OVER THE
SOUTHWESTERN UNITED STATES. A SHORTWAVE TROUGH WILL BE TRAVERSING
THE NORTHERN PLAINS DURING THIS PERIOD, HELPING TO PUSH A COLD FRONT
THROUGH WESTERN KANSAS. WITH PLENTY OF MOISTURE AHEAD OF THE FRONT,
THUNDERSTORMS ARE EXPECTED TO DEVELOP IN NORTHWEST KANSAS WEDNESDAY
AFTERNOON AND THEN MOVE ACROSS SOUTHWEST KANSAS WEDNESDAY EVENING.
GIVEN THE 70KT UPPER LEVEL JET ALONG WITH 2000+ J/KG SURFACE BASED
CAPE, THESE STORMS COULD BE SEVERE WITH HAIL AS LARGE AS GOLFBALLS
AND DAMAGING WIND GUSTS. THE HIGH LEVEL JET WILL SHIFT NORTHWARD INTO
THE NE/SD BY THURSDAY INTO SATURDAY, ALONG WITH THE LOW LEVEL
BAROCLINIC ZONE. SO THE BEST CHANCE FOR STORMS WILL BE TO OUR NORTH
DURING THIS TIME. HIGH TEMPERATURES SHOULD RISE INTO THE 90S
AS MUCH OF SOUTHWEST KANSAS WILL BE IN THE WARM SECTOR WITH SOUTH WINDS.
BY LATE SATURDAY AND SUNDAY, THE AFOREMENTIONED UPPER LEVEL
FEATURES WILL HAVE SHIFTED EASTWARD, WITH THE UPPER LEVEL RIDGE
AXIS ACROSS THE SOUTHERN PLAINS. A STATIONARY FRONT WILL BE
LOCATED ACROSS THE CENTRAL PLAINS WITH PLENTY OF LOW LEVEL
MOISTURE PERSISTING IN VICINITY AND NORTH OF THE FRONT. THEREFORE,
THERE IS A CHANCE OF THUNDERSTORMS SATURDAY NIGHT AND SUNDAY, WITH
HIGH TEMPERATURES MAINLY IN THE LOWER TO MID 90S. AFTER SUNDAY, A
SHORTWAVE TROUGH IS ADVERTISED TO PASS ACROSS THE NORTHERN PLAINS
AND PUSH A COLD FRONT THROUGH WESTERN KANSAS. HIGH TEMPERATURES
SHOULD COOL INTO THE 70S/80S BY EARLY TO MID NEXT WEEK.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON)
ISSUED AT 1151 AM CDT MON JUL 29 2013

AS A STATIONARY FRONT IN FAR SOUTHERN KANSAS MOVES NORTH AND
NORTHEAST TODAY AS A WARM FRONT, CLEAR SKIES WILL SPREAD
NORTHEASTWARD AS WELL.  SURFACE WINDS WILL GENERALLY BE SOUTH TO
SOUTHEAST AT 12G22KT.  WINDS WILL DROP OFF TOWARDS 00Z.  SCATTERED
STRONG TO SEVERE STORMS ARE LIKELY AFTER 21Z, EAST OF A HAYS TO
DODGE CITY LINE.  WITH RECENT WETTING RAINS ACROSS MUCH OF
SOUTHWESTERN KANSAS AND EXPECTED LIGHT WINDS TONIGHT, SOME 1 TO 2
SM LIGHT FOG CAN BE EXPECTED.  THIS FOG MAY BE MORE PATCHY THAN
WIDESPREAD, I HAVE OPTED TO BRING IN 2SM BR AND CIGS IN THE
BKN012-015 RANGE AFTER 09Z TUESDAY MORNING.
