AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HASTINGS NE
950 PM CDT WED SEP 24 2008

.UPDATE...CURRENT FORECAST SEEMS ON TRACK FOR THE REST OF TONIGHT.
LOW LEVEL JET IS INCREASING AND STORMS ARE FIRING WEST OF HIGHWAY
281. COVERAGE HAS BEEN ISOLATED AND WILL LIKELY REMAIN ISOLATED TO
SCATTERED. FOCUS OF CONVECTION WILL PROGRESSIVELY BE FURTHER NORTH
AND EAST AS THE NIGHT GOES ON DUE TO WARM FRONT PUSHING BACK
NORTH AND STRONG LOW LEVEL JET ALSO PUNCHING FURTHER NORTH. AN
ISOLATED SEVERE STORM IS STILL POSSIBLE DUE TO ELEVATED
INSTABILITY BUT NOT OVERLY LIKELY.

&&

.PREV DISCUSSION... /ISSUED 642 PM CDT WED SEP 24 2008/

AVIATION...00Z KGRI TAF. THE POSSIBILITY OF THUNDERSTORMS WILL BE
THE PRIMARY AVIATION HAZARD. THUNDERSTORMS HAVE DEVELOPED ACROSS
NORTH CENTRAL KANSAS EARLY THIS EVENING AND ARE SLOWING MOVING
TOWARDS THE NORTHEAST. THESE THUNDERSTORMS SHOULD DIE OUT BEFORE
REACHING KGRI BUT THE CLOUD TOPS WILL BE VISIBLE ACROSS THE
SOUTHERN HORIZON. THERE IS STILL THE OUTSIDE CHANCE THAT A
THUNDERSTORM COULD DEVELOP FURTHER NORTH NEAR KGRI...AS A WARM
FRONT PUSHES NORTHWARD. HOWEVER...THE POSSIBILITY OF THIS
HAPPENING IS LOW ENOUGH AT THIS TIME TO CONTINUE WITH A DRY TAF
BUT WILL NEED TO MONITOR THUNDERSTORM DEVELOPMENT CLOSELY OVER
THE NEXT SEVERAL HOURS. WINDS WILL REMAIN SOUTHERLY THROUGHOUT THE
TAF VALID PERIOD.

PREV DISCUSSION... /ISSUED 320 PM CDT WED SEP 24 2008/

SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT.

WATER VAPOR IMAGERY FROM THIS AFTERNOON REVEALS A BROAD BUT FLAT
UPPER RIDGE POSITIONED FROM THE DESERT SOUTHWEST INTO THE SOUTHERN
PLAINS.  RIDING ACROSS THE TOP OF THIS RIDGE IS A FAIRLY FAST BUT
ZONAL FLOW REGIME.  EMBEDDED WITHIN THIS FLOW REGIME IS A HEALTHY
SHORT WAVE SEEN MOVING EAST FROM THE NORTHERN HIGH PLAINS INTO THE
CENTRAL ROCKIES.  QUICK EXAMINATION OF REGIONAL SURFACE OBS SHOWS A
DEEPENING LEE TROUGH OVER THE HIGH PLAINS WHILE A NEARLY STALLED
FRONT IS SEEN ACROSS NORTHERN KANSAS.  RUC ANALYSIS ALONG WITH LAPS
DATA SHOWS 0-1KM ML CAPES OF 1000 TO 1500 J/KG ON EITHER SIDE OF
THIS BOUNDARY ALTHOUGH A POCKET OF 1500 TO 2500 CAPE IS SEEN NEAR
KRSL TO KHYS...WHICH SEEMS TO MATCH WITH A CLUSTERING OF CU SHOWN ON
VISIBLE SATELLITE IMAGERY.

AS THE AREA HEADS INTO THIS EVENING...THE AFOREMENTIONED SHORT WAVE
IS SHOWN TO PUSH EAST ACROSS THE PLAINS AS THE UPPER RIDGE BEGINS TO
AMPLIFY OVER THE ROCKIES TO HIGH PLAINS.  THIS IS EXPECTED TO PUSH
THE FRONT OVER NORTHERN KANSAS THIS AFTERNOON...RAPIDLY NORTH INTO
THE NORTHERN PLAINS BY LATE THIS EVENING TO OVERNIGHT HOUR AS A
35 TO 40 KT LLJ FORMS ACROSS THE PLAINS. THE INITIAL QUESTION THIS
PATTERN WILL BRING ABOUT IS IF THE FRONT CAN TRIGGER ANY SURFACE
BASED CONVECTION BEFORE SUNSET STABILIZES THE LOWER 1 KM OF THE
BOUNDARY LAYER. THE NAM CONTINUES TO SHOW THE SAME AREA WITH THE
BEST INSTABILITY/LOW LEVEL LAPSE RATES OVER NORTHERN KANSAS...SLIDING
ONLY SLIGHTLY FURTHER NORTH THROUGH EARLY EVENING. ALTHOUGH INHIBITION
SHOULD BE STRONG ENOUGH TO INHIBIT DEEP CONVECTION OVER MOST OF
THE AREA...EXPECT THE UPPER WAVE TO AID IN PRODUCING ENOUGH LIFT
TO BRING A SLIGHT CHANCE OF CONVECTION INITIALLY OVER NORTH
CENTRAL KANSAS...BUT THEN LIFTING NORTH ACROSS SOUTH CENTRAL
NEBRASKA AS THE BOUNDARY LIFTS NORTH AS WELL. EXPECT THE OVERNIGHT
HOURS TO TURN QUIET AS THE BOUNDARY SHIFTS NORTH OF THE REGION AND
THE NOSE OF THE LLJ PUSHES THE BETTER FORCING INTO THE NORTHERN
PLAINS TO UPPER MIDWEST. SEVERE CONVECTION WISE...ALTHOUGH DEEP
LAYER SHEAR WILL REMAIN MARGINAL AT 25 TO 35 KNOTS NEAR THE
BOUNDARY...CAN/T RULE OUT A FEW STRONG TO SEVERE STORMS AS
WELL...MAINLY OVER NORTH CENTRAL KANSAS THROUGH MID EVENING.

THURSDAY INTO THURSDAY NIGHT ARE THEN LOOKING DRY AND MILD AS THE
UPPER RIDGE AMPLIFIES INTO THE CENTRAL PLAINS.  THIS SHOULD BRING
DECENT SUBSIDENCE TO THE REGION THROUGH THIS TIME PERIOD ALONG WITH
MILD TEMPERATURES.  THE ONLY POTENTIAL PROBLEM WILL BE THE STRENGTH
OF THE WINDS ON THURSDAY AFTERNOON AS THE PRESSURE GRADIENT IS SHOWN
TO TIGHTEN IN RESPONSE TO THE LEE TROUGH DEEPENING OVER THE HIGH
PLAINS.  BUFKIT MOMENTUM TRANSFER DOES SUPPORT SOME GUSTS UP TO 25
TO 30 KNOTS DURING THE AFTERNOON...ALTHOUGH SUSTAINED WINDS AROUND
20 KNOTS LOOKS VERY LIKELY.  TEMPERATURE WISE...GOOD MIXING
CONDITIONS SHOULD SUPPORT HIGHS IN THE MID TO UPPER 80S.

LONG TERM...12Z FRIDAY THROUGH WEDNESDAY. MAIN FORECAST CONCERN
WILL BE A CHANCE OF THUNDERSTORMS SUNDAY AND SUNDAY NIGHT AND
TEMPERATURES.

NEARLY ZONAL FLOW WILL BE ACROSS THE AREA FRIDAY THROUGH SUNDAY DUE
TO A BROAD UPPER RIDGE IN THE WESTERN CONUS. TEMPERATURES SHOULD
REMAIN WARM FOR THIS TIME OF YEAR WITH THE BROAD UPPER RIDGE ACROSS
THE AREA AND TO THE WEST. DURING THIS TIME A WEAK COLD FRONT MOVES
THROUGH THE FORECAST AREA FRIDAY NIGHT. CONDITIONS ARE DRY AND THERE
IS LITTLE UPPER SUPPORT AND EXPECT THAT DRY CONDITIONS WILL PREVAIL
AS THE FRONT MOVES THROUGH. TEMPERATURES WILL COOL DOWN A LITTLE
BEHIND THE FRONT AS IT MOVES THROUGH.

THE ZONAL FLOW GIVES WAY TO AN UPPER LOW THAT MOVE THROUGH THE
NORTHERN PLAINS. A COLD FRONT MOVES THROUGH THE FORECAST AREA SUNDAY
AFTERNOON AND EVENING. EXPECT THAT THERE WILL BE A CHANCE FOR SOME
THUNDERSTORMS AS THIS SYSTEM MOVES THROUGH.

AFTER THE COLD FRONT MOVES THROUGH SUNDAY NIGHT A COLD HIGH PRESSURE
SYSTEM SETTLES INTO THE AREA. TEMPERATURES AT 850MB DROP AS LOW AS 2
TO 4 DEG C AND TEMPERATURES SHOULD ALSO COOL DOWN MONDAY THROUGH
WEDNESDAY.
