AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
358 PM CDT THU AUG 4 2011

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST ISSUE IS THE TIMING AND AREAL COVERAGE OF
THUNDERSTORMS.

THE HIGH-LEVEL JET THAT HAS BEEN SITUATED ACROSS THE NORTHERN
PLAINS FOR MOST OF THE SUMMER HAVE BEGUN, AT LEAST TEMPORARILY, TO
SAG SOUTHWARD TOWARD KANSAS. THIS TREND WILL CONTINUE FOR THE NEXT
SEVERAL DAYS. THIS WILL FAVOR A FURTHER POSITION OF THE SURFACE
FRONT ACROSS CENTRAL OR NORTHERN KANSAS. THEREFORE, THE RICH LOW-
LEVEL MOISTURE THAT HAS BEEN PRESENT ACROSS THE DAKOTAS AND INTO
NEBRASKA THIS SUMMER WILL PROGRESS INTO OUR FORECAST AREA BEHIND
THIS FRONT. A FEW WEAK SHORTWAVE TROUGHS ARE ADVERTISED TO CROSS
THE CENTRAL PLAINS AND HELP FOCUS LOW-LEVEL CONVERGENCE ALONG AND
NORTH OF THE STALLED OUT FRONT. THE TIMING OF THESE FEATURES IS
VERY DIFFICULT TO PINPOINT. SCATTERED TO ISOLATED SURFACE BASED
THUNDERSTORMS ARE POSSIBLE EACH DAY THROUGH SATURDAY AND THEN INTO
NEXT WEEK. ELEVATED THUNDERSTORMS ARE POSSIBLE EACH NIGHT IN A
WARM ADVECTION PATTERN ASSOCIATED WITH THE NOCTURNAL LOW-LEVEL JET
TO THE NORTH OF THE STALLED OUT FRONT. THE BEST CHANCE FOR THESE
NOCTURNAL STORM CLUSTERS IS ALONG THE INTERSTATE 70 CORRIDOR.
UNFORTUNATELY, IT IS VERY DIFFICULT TO PINPOINT EXACTLY WHERE THE
HEAVIEST RAIN WILL BE WITH ANY STORM CLUSTER THAT DEVELOPS. BY SATURDAY
AFTERNOON AND EVENING, THE HIGH-LEVEL JET WILL BE EVEN CLOSER TO
OUR FORECAST AREA, WITH 250MB WINDS APPROACHING 50 KNOTS. SO
SEVERE STORMS WITH LARGE HAIL AND DAMAGING WINDS ARE POSSIBLE JUST
ABOUT ANYWHERE IN CENTRAL AND SOUTHWESTERN KANSAS.

HIGH TEMPERATURES THROUGH SATURDAY WILL DEPEND ON THE THE AMOUNT OF
COOL OUTFLOW FROM ANY NOCTURNAL THUNDERSTORM CLUSTERS. BUT GENERALLY,
THE HOTTEST TEMPERATURES WILL BE ALONG THE OKLAHOMA BORDER, WITH COOLER
TEMPERATURES ALONG INTERSTATE 70 WHERE RAIN COOLED AIR MAY RESIDE
ON THE COOL SIDE OF THE SURFACE FRONT.

FINCH

DAYS 3-7...

MODELS IN GOOD AGREEMENT IN INCREASING THE UPPER FLOW OVER THE
ROCKIES AND INTO THE CENTRAL PLAINS INTO NEXT WEEK. THERE WILL BE
SEVERAL ROUNDS OF LATE AFTERNOON AND OVERNIGHT MESOSCALE CONVECTIVE
COMPLEXES MAINLY IN THE NORTH FA WITH SOME POSSIBLY SEVERE ON
SATURDAY NIGHT INTO MONDAY NIGHT. PLACEMENT OF ANY OUTFLOW
BOUNDARIES WILL BE HARD TO PREDICT FOR DAILY HIGH TEMPERATURE
FORECASTS BUT IN GENERAL THE NORTH WILL BE COOLER AND SOUTH FA
WARMER INTO MONDAY. BY TUESDAY THE JET WILL DIVE MORE SOUTH AS UPPER
LEVEL TROUGHING ENHANCES OVER THE PLAINS AND BRINGS A COLD FRONT
ACROSS KANSAS WITH COOLER NORTH TO EASTERLY UPSLOPE FLOW INTO
THURSDAY. AS FOR TEMPERATURES LOOK FOR OVERNIGHT LOWS IN THE 60 WEST
TO 70 EAST INTO THURSDAY. DAYTIME HIGHS WILL BE TRICKY DEPENDENT ON
JUST WHERE A COLD FRONT WILL END UP AFTER OVERNIGHT CONVECTION. FOR
SUNDAY AND MONDAY HIGHS WILL RANGE FROM THE LOWER 90S NORTH TO
AROUND 105 SOUTHEAST FA. FOR TUESDAY HIGH TEMPS SHOULD BE COOLER AND
IN THE 80S NORTH TO NEAR 100 FAR SOUTH. THEN ON WEDNESDAY AND
THURSDAY WITH COOLER HIGH PRESSURE DOMINATING THE PLAINS HIGHS WILL
RANGE FROM THE MID 80S NORTH TO AROUND 90 SOUTH.

LARGE MESOSCALE COMPLEX OF STORMS SHOULD COME OUT OF NORTHWEST
KANSAS AND COLORADO BY AROUND MIDNIGHT WITH SOME POSSIBLY SEVERE
WITH LARGE HAIL AND DAMAGING WINDS MAINLY NORTH OF A LINE FROM
SYRACUSE TO LARNED AND NORTH WITH THE BEST CHANCE IN THE KHYS
