Did it verify

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
310 PM CDT MON APR 19 2004

.DISCUSSION...

DAYS 1-2...

THE STRONG SHORTWAVE TROUGH THAT MOVED THROUGH YESTERDAY PUSHED A
FRONT INTO NORTHWEST OKLAHOMA THIS MORNING. THIS FRONT STRETCHED
FROM NEAR AMA TO JUST NORTH OF ENID AT 2 PM, AND WAS BASICALLY
STALLED OUT. ANY SFC BASED STORMS THIS AFTERNOON WILL BE ALONG THIS
FRONT AND WILL NOT AFFECT SW KS. LATE THIS EVENING AS THE SHORTWAVE
APPROACHES, A 40-50KT LOW-LEVEL JET WILL DEVELOP ACROSS NORTHERN
OKLAHOMA AND SOUTHERN KANSAS. STRONG CONVERGENCE ON THE NORTH SIDE
OF THIS JET WILL LEAD TO THUNDERSTORM DEVELOPMENT. SINCE THE STORMS
WILL BE ELEVATED, WE DO NOT EXPECT A DAMAGING WIND OR TORNADO
THREAT. THE STRONGEST STORMS MAY PRODUCE HAIL UP TO QUARTER SIZE.
DESPITE THE MODERATE ELEVATED INSTABILITY, THE SHEAR WILL BE MAINLY
CONFINED TO THE LOW LEVELS, WITH FAIRLY UNIFORM FLOW ABOVE 850MB,
YIELDING ONLY MODEST ELEVATED SHEAR. POPS WERE RAISED TO 60-70% FOR
THE EASTERN PART OF THE FCST AREA, WITH 30-50 POPS CENTRAL AND WEST.
ONCE THE WARM ADVECTION PATTERN WEAKENS TOWARD MORNING, THE PRECIP
WILL CUT OFF, EVEN THOUGH THE TROUGH AXIS WILL NOT BE THROUGH YET.
TUESDAY WILL BE BREEZY AND MILD WITH DOWNSLOPE FLOW BEHIND THE
PACIFIC COLD FRONT, AND LITTLE CHANCE FOR RAIN. WITH MOSTLY CLEAR
SKIES TUE NIGHT AND LOW DEWPOINTS, LOWS SHOULD EASILY FALL INTO THE
40S, WITH UPPER 30S TO LOWER 40S IN THE NORTH AND WEST. SURFACE HIGH
PRESSURE WILL BE PARKED OVER THE CENTRAL AND SOUTHERN PLAINS
WEDNESDAY, WITH PARTLY CLOUDY SKIES AND LITTLE CHANCE FOR RAIN.

DAYS 3-7...

THE LATEST RUN OF THE GFS AGREES WITH THE ECMWF OUT THROUGH 120HRS
OR 24/00Z THAT A SIGNIFICANT SHORT WAVE IN THE 5H FLOW WILL CROSS
THE ROCKIES AROUND THURSDAY AND PLOW THROUGH SOUTHERN KANSAS
AFTERWARDS.  THE GFS IS A LITTLE FASTER AND OVERALL DEEPER WITH THIS
UPPER FEATURE, AND GENERATES PLENTY OF PRECIP COVERAGE FROM THURSDAY
AFTERNOON THROUGH FRIDAY NIGHT.  HAVE THEREFORE ADDED CHANCE POPS TO
FRIDAY PERIOD, AND KEPT CHC GOING IN EASTERN CWA FRIDAY NIGHT WHILE
KEEPING SLIGHT CHC POPS IN CENTRAL CWA FRI NIGHT.  AFTER 120 HOURS
OR 24/00Z, THE LONG RANGE MODELS DIVERGE IN BOTH THE STRENGTH AND
PATH OF THE NEXT UPPER SYSTEM.  FOR NOW, LEANED TOWARD THE GFS BUT
KEPT SAT-SUN-MON DRY.  AS FOR TEMPERATURES, THE GOING FORECAST
LOOKED REASONABLE.  HIGHS ON FRIDAY MAY BE THWARTED A BIT DUE TO
PRECIP.  HIGHS BOTH THURSDAY AND FRIDAY WILL DEPEND ON HOW FAR NORTH
THE FRONT WILL TRAVEL AS A WARM FRONT NORTHWARD FROM TX/OK.  STAYED
CLOSE TO MEX GUIDANCE NUMBERS BEYOND FRIDAY, WHICH ARE FAVORING
SLIGHTLY BELOW NORMAL.
