AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
335 PM CDT THU JUL 28 2011

.DISCUSSION...

.SHORT TERM...

THE 12 UTC UPPER AIR SUBJECTIVE ANALYSIS INDICATES AN UPPER JET
MOVING THROUGH THE NORTHERN PLAINS STATES WHILE A WEAK TROUGH AND
COLD POOL ACROSS THE FAR NORTHERN ROCKIES AT 500 MB ALSO MIGRATED
EASTWARD. A LARGE WARM PLUME OF VERY WARM AIR STILL ENCOMPASSED THE
CENTRAL AND SOUTHERN ROCKIES. INCREASING MOISTURE INTO THE CENTRAL
PLAINS AT 850 MB WAS NOTED AS THE 16 DEG C ISODROSOTHERM EXTENDED
FROM THE SOUTHEAST US INTO NORTHERN KANSAS, WITH PRECIPITABLE
WATER VALUES IN EXCESS OF 150 PERCENT OF NORMAL AT DODGE CITY.

WIDELY SCATTERED ELEVATED THUNDERSTORMS HAVE DEVELOPED ALREADY IN
THIS VERY UNSTABLE AIRMASS ACROSS THE WESTERN AND NORTHWEST PORTIONS
OF OUR FORECAST AREA THIS AFTERNOON. WE ONLY EXPECT THIS ACTIVITY TO
CONTINUE TO EXPAND THROUGH THE LATE AFTERNOON AND EVENING. THERE IS
WEAK UPPER FORCING IS ALL THAT WE ARE SEEING AT THIS TIME, SO WE ARE
NOT EXPECTING VERY WELL ORGANIZED THUNDERSTORMS FOR WIDESPREAD HEAVY
RAINS OR TRAINING. ABOUT 30 KNOTS OF BULK SHEAR MIGHT LEAD TO WEAKLY
ROTATING CELLS HOWEVER, ABLE TO PRODUCE ISOLATED LARGE HAIL AND
DAMAGING WIND THIS EVENING.

IF THE STORMS REMAIN SCATTERED AT BEST, THERE MAY BE LITTLE MOVEMENT
OF THE SYNOPTIC BOUNDARY DUE TO EXCESSIVE CONVECTIVE OUTFLOW THROUGH
FRIDAY AFTERNOON. THE MODELS IN GENERAL ARE INDICATING THE FRONT BE
PUSHED FARTHER SOUTHWARD TO THE OKLAHOMA LINE, WHICH WOULD ALLOW
REGENERATION OF CONVECTION LATE FRIDAY FOCUSED MORE ON THE CENTRAL
AND SOUTHERN FORECAST AREA. THAT BEING SAID, THE UPPER JET SHOULD BE
POSITIONED ZONALLY ACROSS SOUTH DAKOTA AND NEBRASKA AGAIN FRIDAY,
WHICH MAY CREATE ENHANCED UPPER DIVERGENCE ACROSS NORTHERN KANSAS.
THEREFORE, ANY WHERE IN THE FORECAST AREA HAS AT LEAST A SMALL
CHANCE OF THUNDERSTORMS TOMORROW, AND WE WILL LIKELY SEE A REPEAT OF
SCATTERED HEAVY RAIN PRODUCING CONVECTION. CLOUDS/CONVECTION TODAY AND
ADDITIONAL CHANCES TONIGHT SHOULD PROVIDE SOME RELIEF TO THE
WIDESPREAD 100 DEGREE TEMPERATURES ON FRIDAY WITH TEMPERATURES IN
THE LOW TO UPPER 90S. SATURDAY PRESENTS MORE OF A FORECAST CHALLENGE
WITH RESPECT TO WHERE THE SYNOPTIC BOUNDARY MIGHT WIND UP BEING
POSITIONED. THE CONSENSUS HOWEVER IS FOR TEMPERATURES TO WARM BACK
INTO THE 100+ DEGREE ZONE WITH THE ECMWF AND GFS BOTH MAINTAINING AN
ESSENTIALLY DRY FORECAST ACROSS THE DDC FORECAST AREA. AN OUTLYING
WRF/NAM WILL EXTEND CONVECTION FARTHER WEST INTO SOUTHCENTRAL
KANSAS.

.LONG TERM...

THE SHORTWAVE TROUGH AND ASSOCIATED JET STREAK MENTIONED IN THE DAYS 1-2
DISCUSSION WILL BE MOVING AWAY FROM OUR AREA BY FRIDAY NIGHT AND
SATURDAY, AND WE WILL NO LONGER BE IN THE RIGHT ENTRANCE REGION OF
THE JET. IN ADDITION, THE NEXT SHORTWAVE TROUGH WILL BE PASSING ACROSS
SASKATCHEWAN BY SATURDAY. LEE TROUGHING AHEAD OF THIS FEATURE WILL
RESULT IN LOW-LEVEL FRONTOLYSIS ACROSS KANSAS SINCE SURFACE WINDS
WILL BE SOUTHERLY UP AND DOWN THE PLAINS. SO IN THE ABSENCE OF JET
FEATURES AND FRONTS THAT WOULD PROMOTE LIFT, ANYTHING MORE THAN VERY
ISOLATED THUNDERSTORMS IS NOT EXPECTED. THIS SHORTWAVE TROUGH IS NOT
EXPECTED TO BE STRONG ENOUGH OR FAR ENOUGH SOUTH TO HELP PUSH A COLD
FRONT THROUGH OUR FORECAST AREA. BY SUNDAY AND MONDAY, UPPER LEVEL
RIDGING WILL BUILD ACROSS THE CENTRAL PLAINS AS THE NEXT SHORTWAVE
TROUGH APPROACHES MANITOBA. THIS SHORTWAVE TROUGH WILL RESULT IN LEE
TROUGHING ONCE AGAIN UP AND DOWN THE PLAINS. SO ANYTHING MORE THAN
ISOLATED THUNDERSTORMS IS STILL NOT EXPECTED IN THE ABSENCE OF
LOW-LEVEL CONVERGENCE. IN ADDITION, LOW LEVEL TRAJECTORIES ARE
ADVERTISED TO BE SOUTHERLY INSTEAD OF SOUTHWESTERLY, SO EXTREME HEAT
SHOULD BE ABSENT. NEVERTHELESS, IT WILL STILL BE HOT WITH HIGHS IN
THE UPPER 90S TO AROUND 102.

FROM TUESDAY INTO FRIDAY, THE UPPER-LEVEL RIDGE IS ADVERTISED BY ALL
THE MODELS TO FLATTEN OUT, WITH MAINLY ZONAL FLOW ACROSS THE CENTRAL
AND NORTHERN PLAINS. HOWEVER, A SURFACE FRONT THAT PROGRESSES DOWN
THE PLAINS IN THE WAKE OF A SHORTWAVE TROUGH TUESDAY NIGHT IS EXPECTED
TO STALL OUT ACROSS OUR FORECAST AREA FOR A FEW DAYS. THERE WILL BE
OPPORTUNITIES FOR ISOLATED TO SCATTERED THUNDERSTORMS ALONG THIS
FRONT EACH DAY THROUGH SATURDAY AUGUST 5TH. SOUTH OF THE FRONT IT
WILL BE EXTREMELY HOT GIVEN THE EXPECTED LOW TO MID-LEVEL DOWNSLOPE
FLOW TO THE NORTH OF THE FLAT 500MB RIDGE AXIS. TEMPERATURES IN OUR
SOUTHERN COUNTIES COULD REACH TO BETWEEN 105F AND 110 EACH DAY. IT IS
UNCLEAR EXACTLY WHERE THIS FRONT WILL BE. SO THE EXTREME HEAT COULD
EASILY EXTEND NORTHWARD TO INCLUDE DODGE CITY AND GARDEN CITY.
