AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
311 AM CDT MON MAY 5 2008

.DISCUSSION...

DAYS 1-2...

SUBTROPICAL JET WAS MOVING ACROSS THE SOUTHERN PORTIONS OF THE CONUS
AT 00Z THIS EVENING. H5 LOW WAS INTENSIFYING OFF OF THE SOUTHERN CA
COAST WITH HEIGHT FALLS OF 50 METERS AT OAKLAND, CA. H7 TEMPERATURES
ACROSS SOUTHWEST KANSAS WERE IN THE SINGLE DIGITS ABOVE 0C AS
PORTIONS OF NORTHERN KS WERE EXPERIENCING TEMPERATURES JUST BELOW
0C. H85 TEMPERATURES WERE IN THE TEENS ABOVE 0C ACROSS WESTERN KS
WHILE READINGS TO THE EAST WERE SEVERAL DEGREES COOLER. GULF
MOISTURE WAS ON THE RETURN ACROSS WESTERN TX, WITH THE HELP OF THE
30KT LOW LEVEL JET. 10C TO 14C DEWPOINTS WERE SURGING NORTHWEST AND
HAD NOSED INTO MIDLAND, TX.

MAIN FORECAST CONCERN WILL FOCUS ON SEVERE THUNDERSTORM CHANCES
TODAY AND TUESDAY.

MOISTURE CONTINUES TO SURGE NORTHWARD THIS MORNING. 04Z OBS ARE VERY
SIMILAR TO NAM WITH DEWPOINTS ACROSS THE TX PANHANDLE AND WESTERN
KS. GFS IS A BIT MORE MOIST EARLY ON AS IS THE ECMWF. ALREADY SEEING
SOME THUNDERSTORMS DEVELOPING ACROSS WESTERN TX. NAM HAS A BIT
STRONGER LOW LEVEL JET MOVING ACROSS THE AREA BY MORNING BUT ECMWF
IS NOT FAR OFF. BOTH SHOW A 30 TO 40 KT LLJ MOVING INTO SOUTHWEST
KANSAS BY 12Z THIS MORNING. MID LEVEL BAROCLINIC ZONE IS SITUATED
NEAR SUBLETTE TO WAKEENEY AREA. THUNDERSTORMS COULD DEVELOP IN THIS
VICINITY TOWARD MORNING.  RADAR RETURNS ALREADY TRYING TO PICK UP A
FEW ECHOS ACROSS THE REGION. STILL LOOKS VERY POSSIBLE THAT A FEW
ELEVATED STORMS DEVELOP BY EARLY MORNING AS MOST UNSTABLE CAPE BY
12Z IS NEAR 1000 J/KG ACROSS THIS SECTION OF THE FA. BY 18Z, MODELS
ARE IN AGREEMENT THAT MOST UNSTABLE CAPE REACHES 2000 J/KG. DURING
THIS TIME, DEWPOINTS SHOULD BE IN THE 50S ACROSS THE FA. A DRYLINE
WILL BE PRESENT ACROSS WESTERN COLORADO NEAR THE KS BORDER. THERE
WILL BE A LITTLE MOVEMENT DURING THE DAYTIME. A FEW SUPERCELLS ARE
EXPECTED TO FORM ALONG THE DRYLINE. UPPER FLOW WILL ALLOW THESE
STORMS TO MOVE EAST INTO DEEPER MOISTURE. 0-6KM SHEAR IS IN EXCESS
OF 40 KTS ACROSS SOUTHWEST KANSAS TODAY. ANY STORMS THAT DO FORM
WILL BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS. AN
ISOLATED TORNADO CANNOT BE RULED OUT GIVEN LEFTOVER BOUNDARIES FROM
EARLIER CONVECTION.

DRYLINE WILL RETREAT WEST TONIGHT. STORMS WILL MOVE ACROSS THE
EASTERN FA OVERNIGHT. WILL KEEP A SLIGHT CHANCE OF THUNDERSTORMS IN
ACROSS THE CENTRAL PART OF THE FA WILL BUT WILL LEAVE WEST DRY. AS
THE DRYLINE RETREATS WEST, HIGHER DEWPOINTS WILL FOLLOW. THIS WILL
ALLOW TEMPERATURES TO REMAIN ON THE MILD SIDE ACROSS THE FA.
GENERALLY, TEMPERATURES IN THE 50S AND 60S WILL BE LIKELY TONIGHT.

BY TUESDAY, UPPER LOW WILL TRACK EAST FROM SOUTHERN CA. THIS WILL
ALLOW S/WVS TO MOVE ACROSS SOUTHWEST KANSAS DURING THE AFTERNOON
INTO THE EVENING. DEWPOINTS WILL CONTINUE TO BE IN THE 50S AND 60S
AS THE DRYLINE BEGINS ITS MARCH EASTWARD. BY 18Z TUE, IT SHOULD BE
INTO WESTERN PORTIONS OF THE FA. SEVERAL OUTFLOW BOUNDARIES FROM
MONDAYS STORMS WILL BE ACROSS THE FA DURING THE DAY. IN ADDITION TO
THESE BOUNDARIES IN ADVANCE OF THE DRYLINE, CAPES WILL IN EXCESS OF
2000 J/KG. SUPERCELLS WILL ONCE AGAIN BE POSSIBLE DURING THE
AFTERNOON AND EVENING HOURS. THIS TIME, THE ACTIVITY WILL BE A BIT
FURTHER EAST. FROM DIGHTON TO GARDEN CITY TO LIBERAL AND EAST COULD
SEE THUNDERSTORMS WILL LARGE HAIL AND DAMAGING WINDS. AGAIN, GIVEN
THE BOUNDARIES FROM EARLIER STORMS, AN ISOLATED TORNADO IS POSSIBLE.
AS THE SURFACE LOW INTENSIFIES AND MOVES EAST, SHOWERS AND
THUNDERSTORMS WILL FILL IN ACROSS SOUTHWEST KANSAS. 310K ISENTROPIC
LIFT WILL INCREASE DURING THE OVERNIGHT HOURS WITH SPECIFIC HUMIDITY
VALUES IN EXCESS OF 7 G/KG. PRECIPITABLE WATER VALUES IN EXCESS OF 1
INCH WILL BE PRESENT ACROSS THE EASTERN PORTIONS OF THE FA. WILL
CONTINUE WITH THE CHANCE FOR SHOWERS AND THUNDERSTORMS DURING THE
OVERNIGHT HOURS TUESDAY. TEMPERATURES WILL REMAIN MILD ONCE AGAIN AS
PLENTY OF MOISTURE LINGERS ACROSS THE EASTERN FA. FURTHER WEST, AS
THE SURFACE LOW MOVES EAST, COOLER AND DRIER CONDITIONS WILL TAKE
HOLD. TEMPERATURES IN THE NORTHWESTERN FA COULD DIP INTO THE 40S
TOWARD WEDNESDAY MORNING.

DAYS 3-7...

NUMERICAL MODELS REMAIN IN GENERAL AGREEMENT SINCE YESTERDAY
INDICATING AN UPPER LEVEL TROUGH OF LOW PRESSURE LIFTING NORTHEAST
ACROSS EASTERN NEW MEXICO AND INTO THE TEXAS AND OKLAHOMA PANHANDLES
REGION BY MID DAY WEDNESDAY. THIS SYSTEM WILL BRING A THE POSSIBILITY
FOR PRECIP ACROSS WESTERN KANSAS WEDNESDAY BEFORE IT EXITS THE
REGION TO THE EAST BY THURSDAY. AT THE SURFACE, A DEVELOPING LOW
PRESSURE CENTER WILL MOVE EAST ACROSS SOUTHWEST KANSAS AND THE
PANHANDLES OF TEXAS AND OKLAHOMA DURING THE DAY WEDNESDAY. A LOW
LEVEL SOUTHERLY FLOW WILL INITIALLY BE IN PLACE EARLY WEDNESDAY
WHICH WILL ADVECT A FAIR AMOUNT OF MOISTURE INTO SOUTH CENTRAL AND
PORTIONS OF SOUTHWEST KANSAS. DEWPOINTS AT H85 RANGING UP INTO THE
LOW TEENS(C) WILL PUSH NORTH WELL INTO CENTRAL KANSAS BEFORE
WRAPPING AROUND THE LOW. THIS WILL GIVE EASTERN AND NORTHERN
PORTIONS OF THE CWA A BETTER OPPORTUNITY FOR PRECIP...MAINLY IN WRAP
AROUND CONDITIONS...THROUGH WEDNESDAY NIGHT AS THE SYSTEM TRACKS
EAST OF THE FORECAST AREA. PLAN NO REAL CHANGE IN CURRENT POPS.

EXPECT COOLER TEMPERATURES ON WEDNESDAY AS THE SURFACE LOW MOVES
EAST SWITCHING WINDS TO THE NORTH BY AFTERNOON. INCREASED CLOUDINESS
AND ANY PRECIP ACTIVITY WILL ALSO HELP KEEP TEMPERATURES DOWN.
TEMPERATURES AT H85 WILL RANGE FROM THE LOWER TEENS(C) NORTHEAST TO
THE MID TEENS(C) SOUTHWEST. A FAIRLY ZONAL FLOW ALOFT WILL SETTLE IN
ACROSS THE CENTRAL PLAINS THROUGH THE END OF THE WEEK WHICH WILL
ALLOW TEMPERATURES TO GRADUALLY WARM UP THROUGH FRIDAY. PLAN ON
MAKING ONLY SLIGHT ADJUSTMENTS TO TEMPERATURES.

&&

.AVIATION...

A LEE SIDE TROUGH OF LOW PRESSURE WILL PERSIST IN PORTIONS OF
EASTERN COLORADO AND WESTERN KANSAS TODAY. EXPECT VFR CONDITIONS
THROUGH THIS AFTERNOON WITH PERIOD OF HIGH CLOUDS AND SOUTHERLY
WINDS. THE POSSIBILITY FOR A FEW ISOLATED THUNDERSTORMS EXISTS LATE
THIS AFTERNOON AND EVENING NEAR ALL TAF SITES. MVFR CEILINGS MAY BE
POSSIBLE IN OR AROUND ANY POSSIBLE STORM. WILL ONLY CARRY A MENTION
OF CBS IN TAFS AT THIS POINT.
