Area forecast discussion, Apr 22, 2:59 PM CDT, 5 hours 7 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
259 PM CDT WED APR 22 2009

.DISCUSSION...

DAYS 1-2...

THE MAIN FORECAST CHALLENGES ARE FOR A FEW HIGH BASED THUNDERSTORMS
MAINLY NORTH OF DODGE THIS EVENING, THEN POSSIBLE WIND ADVISORY AND
FIRE WEATHER WATCH FOR FRIDAY.

A WEAK MID LEVEL WAVE IN WESTERLY FLOW ALOFT WILL MOVE EAST ACROSS
THE NORTHERN FA TONIGHT PROVIDING ENOUGH LIFT FOR A FEW HIGH BASED
THUNDERSTORMS. FORECAST SOUNDINGS INDICATE STEEP MID LEVEL LAPSE
RATES AND MID LEVEL MOISTURE. LOW LEVEL MOISTURE IS FAIRLY SHALLOW
AND WAS MIXING OUT AROUND DODGE CITY. MODELS FORECASTING AROUND 1000
J/KG AND MAYBE A FEW COULD PRODUCE SOME SMALL HAIL. THE WRF SEEMS
TOO HAVE LOTS OF CONVECTIVE FEEDBACK PROBLEMS WITH OVER 1.5 INCHES
OF RAIN IN THE HAYS AREA AND PUSHING A GOOD COLD POOL OUT TONIGHT
WITH WINDS BECOMING NORTH. WILL GO MORE WITH THE GFS FOR TONIGHT
WINDS AND PRECIP WITH 30 POPS NORTH AND LESSER SOUTH. LOWS TONIGHT
IN THE LOW TO MID 50S LOOK REASONABLE.

FOR THURSDAY WE WILL BE IN BETWEEN SYSTEMS AS LAST NIGHTS SHORTWAVE
IS MOVING EAST AND A SOUTHERN BRANCH WAVE MOVE INTO NEW MEXICO.
DEWPOINTS CLIMB INTO THE 50S IN THE EAST FA WITH LIGHT AND VARIABLE
WINDS BECOMING SOUTH 5 TO 15 MPH IN THE AFTERNOON. HIGHS WITH 850
TEMPS AROUND 22C WITH A FEW DEGREES FOR SUPER ADIABATIC LAPSE RATE
AT THE GROUND LOOK TO BE IN THE MID TO UPPER 80S. MET GUIDANCE LOOKS
A BIT COOL FOR HIGHS AND WILL GO WITH 2 METER NAM TEMPS. A WEAK CAP
SHOULD ALSO KEEP ANY THUNDERSTORM CHANCES VERY MINIMAL.

ON THURSDAY NIGHT SOUTH WINDS CONTINUE AT 10 TO 15 FOR ANOTHER MILD
NIGHT IN THE MID 50S. ON FRIDAY THE SOUTHERN BRANCH SHORTWAVE TROUGH
WILL MOVE SOUTH OF THE AREA ACROSS THE SOUTHERN PLAINS. WITH VERY
DRY MEAN LAYER IN PLACE WE SHOULD STAY OUT OF ANY THUNDERSTORMS. THE
FAR SOUTHWEST COUNTIES LOOK VERY DRY BY AFTERNOON AND WITH DEEP
MIXING COULD HAVE WINDS OF 15 TO 25KTS. THIS WOULD BE CLOSE TO
CRITICAL FIRE WEATHER CONDITIONS AND WILL CONTINUE TO MONITOR. IN
THE EAST FA WINDS COULD GET TO NEAR WIND ADVISORY CRITERIA.

DAYS 3-7...

AN UPPER LEVEL TROUGH OF LOW PRESSURE WILL BE IN PLACE ACROSS THE
WESTERN CONUS WITH A SOUTHWESTERLY FLOW ALOFT ACROSS THE CENTRAL
PLAINS TO BEGIN THE PERIOD FRIDAY NIGHT. MEDIUM RANGE MODELS ARE IN
FAIR AGREEMENT INDICATING THIS LARGE SCALE PATTERN REMAINING
RELATIVELY UNCHANGED THROUGH EARLY NEXT WEEK. HOWEVER, DURING THIS
TIME PERIOD, A SERIES OF UPPER LEVEL S/WAVE TROUGHS WILL BE EJECTED
NORTHEAST ACROSS THE CENTRAL PLAINS BEGINNING WITH ONE IN THE LATE
SATURDAY TO EARLY SUNDAY TIME FRAME. THIS SET UP COULD BRING THE
POSSIBILITY FOR PRECIP ACROSS PORTIONS OF WESTERN KANSAS BOTH DAYS
OF THE WEEKEND AND INTO NEXT WEEK. THERE IS SOME MODEL DISCREPANCY
IN TIMING BUT BOTH GFS AND ECMWF INDICATE A COLD FRONT ASSOCIATED
WITH THE FIRST UPPER LEVEL S/WAVE PUSHING INTO WESTERN KANSAS
SOMETIME IN THE SATURDAY NIGHT TO SUNDAY MORNING TIME FRAME BEFORE
STALLING, OR AT LEAST SLOWING, IN THE GENERAL VICINITY OF SOUTHWEST
KANSAS AND THE PANHANDLES OF OKLAHOMA AND TEXAS. THE GFS AND ECMWF
ALSO SHOW A SURFACE LOW DEVELOPING IN EASTERN COLORADO SATURDAY
SETTING UP A NICE MOISTURE RETURN UP THROUGH OKLAHOMA AND INTO
EASTERN AND CENTRAL KANSAS. THE QUESTION WILL BE HOW FAR WEST THIS
MOISTURE REACHES AS A DEVELOPING DRYLINE EXTENDS GENERALLY SOUTH
FROM SOUTHWEST KANSAS DOWN INTO THE OKLAHOMA AND TEXAS PANHANDLES.
DETAILS ARE STILL A LITTLE UNCERTAIN AS TO THE TIMING AND LOCATION
OF THE FRONT AND WHERE THE DRYLINE SETS UP, BUT THUNDERSTORMS WILL
BE POSSIBLE SATURDAY AND SUNDAY WITH THE BETTER CHANCE FOR PRECIP
ACROSS THE EASTERN PORTION OF THE CWA WHERE LOW LEVEL MOISTURE WILL
POSSIBLY BE MORE READILY AVAILABLE. AS A RESULT, PLAN TO INCREASE 20
POPS UP TO 30 EAST AND KEEP SLIGHT POPS WEST.

TEMPERATURES WILL BE ABOVE NORMAL SATURDAY AHEAD OF A COLD FRONT
THAT WILL PUSH THROUGH WESTERN KANSAS IN THE SATURDAY NIGHT TO
SUNDAY MORNING TIME FRAME. THE GFS AND ECMWF INDICATE TEMPERATURES
AT H85 RANGING FROM THE UPPER TEENS(C) EAST TO THE MID 20S(C) IN THE
EXTREME SOUTHWEST. EXPECT HIGHS SATURDAY IN THE 70S(F) TO LOW 80S(F)
ACROSS SOUTHWEST KANSAS. TEMPERATURES CAN THEN BE EXPECTED TO DROP
BACK DOWN TO NEAR NORMAL THROUGH THE MIDDLE OF NEXT WEEK AS A RESULT
OF THE FRONTAL BOUNDARY PUSHING THROUGH AND POSSIBLY LINGERING. PLAN
TO LOWER HIGHS A COUPLE DEGREES OR SO SUNDAY AND LOW TEMPERATURES AS
WELL SUNDAY NIGHT WITH MINOR ADJUSTMENTS ELSEWHERE.

.AVIATION...

UPPER LEVEL DISTURBANCE WILL MOVE EAST ACROSS WESTERN KANSAS EARLY
THIS EVENING. THIS WILL CREATE THE POSSIBILITY FOR A FEW ISOLATED
THUNDERSTORMS INTO THE OVERNIGHT HOURS ACROSS MORE NORTHERN PORTIONS
OF THE FORECAST AREA, INCLUDING POTENTIALLY IN THE VICINITY OF KHYS.
AGAIN, ANY STORMS WILL BE ISOLATED IN NATURE SO WILL CONTINUE TO
CARRY A CB ANNOTATION AND POSSIBLY CONSIDER VCTS. OTHERWISE, VFR
CONDITIONS WILL PERSIST THROUGH MID DAY THURSDAY. WINDS WILL BE
LIGHT OUT OF THE SOUTHEAST EARLY THIS EVENING BEFORE BECOMING LIGHT
AND VARIABLE AFTER MIDNIGHT.
