AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
1200 AM CDT SAT MAR 30 2013

...UPDATE TO AVIATION FOR 06Z TAFS...

.SYNOPSIS...
ISSUED AT 1100 PM CDT FRI MAR 29 2013

THE 30.00Z 250 HPA RAOB MAP SHOWED SOUTHWESTERLY FLOW ACROSS THE WESTERN
UNITED STATES DOWNSTREAM OF A LARGE PRESSURE PERTURBATION. ACROSS THE
PLAINS, FLOW WAS WESTERLY AND FAIRLY WEAK - 50 KT AT KDDC. AT 500 HPA,
THE GEOPOTENTIAL HEIGHT PATTERN (VIA MODELS SINCE THERE ARE NO RAOBS
OUT IN THE OCEAN) AND SATELLITE WATER VAPOR CHANNEL SHOWED A LARGE GYRE
LOCATED ACROSS THE EASTERN PACIFIC. THIS FEATURE WAS QUITE IMPRESSIVE
VIA THE AFOREMENTIONED IMAGERY AND ONE CAN CLEARLY SEE VORT LOBES UNDERGOING
THE FUJIWHARA EFFECT AROUND EACH OTHER. CLOSER TO HOME, A MINOR SHORTWAVE
WAS MOVING ACROSS THE CENTRAL PLAINS. MINOR WARMING WAS NOTED AT 850
HPA ACROSS WESTERN KANSAS. THE KDDC RAOB WAS ALSO INTERESTING FROM A
CONVECTIVE STANDPOINT AND INDICATED AN UNSTABLE ATMOSPHERE. SURFACE
BASED CONVECTIVE AVAILABLE POTENTIAL ENERGY WAS INTEGRATED/CALCULATED
AT 1963 J/KG. THE KINEMATIC PROFILE DISPLAYED ADEQUATE VEERING OF WINDS
THOUGH THE LOWER TROPOSPHERE, ALTHOUGH SPEED SHEAR WAS ON THE WEAKER
SIDE FROM THE SFC TO 500 HPA. AT THE SFC, A WARM FRONT WAS LOCATED ACROSS
PORTIONS OF KS/OK WITH DEWS RUNNING IN THE 50S DEG F SOUTH OF THE BOUNDARY.
A SURFACE TROF WAS ANALYZED ACROSS WESTERN KANSAS. KDDC WSR-88D INDICATED
CONVECTION ACROSS THE REGION.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 216 PM CDT FRI MAR 29 2013

THE MAIN FORECAST CHALLENGES ARE CHANCES FOR THUNDERSTORMS TONIGHT.

AN UPPER LEVEL SHORTWAVE TROUGH MOVING INTO THE ROCKIES WILL MOVE
ACROSS WESTERN KANSAS TONIGHT. FORECAST CAPE VALUES AHEAD OF THE
TROUGH ARE AROUND 1000 J/KG. MOIST UPSLOPE FLOW WILL CONTINUE AHEAD
OF THE TROUGH WITH A WEAK COLD FRONT OR WIND SHIFT SHIFTING WINDS TO
THE WEST AND NORTHWEST AFTER MIDNIGHT TO AROUND DAWN. THUNDERSTORMS,
ALONG WITH AREAS OF FOG AND STRATUS LATER ON TONIGHT, WILL BE
POSSIBLE MAINLY ALONG AND AHEAD OF THE WIND SHIFT LINE IN THE BEST
MOISTURE CONVERGENCE, STARTING IN FAR WESTERN KANSAS EARLY THIS
EVENING THEN PROGRESSING ACROSS THE REST OF SOUTHWEST AND SOUTH
CENTRAL KANSAS DURING THE REST OF THE EVENING AND OVERNIGHT.
THUNDERSTORMS LOOK TO END IN THE SOUTH CENTRAL SECTIONS BY 7 AM.
WILL KEEP THE 20 TO 40 PERCENT CHANCES GOING FOR TONIGHT. SOME OF
THE THUNDERSTORMS MAY BE CAPABLE OF SMALL HAIL TO DIME SIZE AND WIND
GUSTS TO 40 OR 50 MPH.

FOR SATURDAY THE WINDS WILL BE FROM THE NORTHWEST AT 10 TO 20 MPH
AND HAVE REMOVED OR DECREASED CHANCES FOR THUNDERSTORMS TO LESS THAN
10 PERCENT. A MUCH DRIER AIRMASS WILL MOVE INTO WESTERN KANSAS
BEHIND THE WIND SHIFT WITH MOSTLY SUNNY SKIES EXPECTED.

OVERNIGHT LOWS WILL BE MILD IN THE LOW TO MID 40S, AND AROUND 50 IN
PARTS OF SOUTH CENTRAL SECTIONS FROM PRATT TO MEDICINE LODGE. HIGHS
ON SATURDAY WARM INTO THE LOW TO MID 70S.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 359 PM CDT FRI MAR 29 2013

TWO MAIN UPPER LEVEL FEATURES WILL HAVE A MAJOR IMPACT ON THE
WEATHER ACROSS THE HIGH PLAINS BY SUNDAY NIGHT THROUGH NEXT WEEK.
ONE STRONG UPPER LEVEL TROUGH WILL BE DROPPING SOUTHEASTWARD OUT
OF CANADA INTO THE UPPER MIDWEST BY MONDAY. THIS WILL PUSH A  COLD
FRONT THROUGH WESTERN KANSAS BY EARLY MONDAY MORNING. ANOTHER UPPER
LEVEL TROUGH WILL BE COMING ONSHORE INTO CALIFORNIA BY SUNDAY AND THEN
WILL SLOWLY PROGRESS ACROSS THE SOUTHERN ROCKIES BY TUESDAY AND INTO
THE SOUTHERN PLAINS BY WEDNESDAY AND THURSDAY. THE ECMWF AND GEM
WERE GENERALLY ACCEPTED THROUGH EARLY TO MID NEXT WEEK AS THE NCEP
MODELS WERE STILL TOO PROGRESSIVE WITH THE UPPER LEVEL TROUGH COMING
ONSHORE. THE COLD FRONT ASSOCIATED WITH THE UPPER MIDWEST UPPER LEVEL
TROUGH WILL PASS ACROSS WESTERN KANSAS EARLY MONDAY MORNING. IT
WILL BE WARM AHEAD OF THE FRONT WITH HIGHS IN THE LOWER 70S
SUNDAY. MUCH COOLER AIR WILL PUSH INTO SOUTHWEST KANSAS MONDAY
WITH HIGHS ONLY IN THE LOWER TO MID 40S. THE HIGHS NEAR THE
OKLAHOMA BORDER WILL PROBABLY BE IN THE MORNING AS THE FRONT
PASSES. ON THE COLD SIDE OF THE FRONT, THERE MAY BE ENOUGH
ISENTROPIC LIFT FOR A FEW RAIN SHOWERS SUNDAY NIGHT AND RAIN OR
SNOW FOR MONDAY. BUT THIS DOES NOT LOOK LIKE A MAJOR PRECIPITATION
EVENT. AS THE WESTERN TROUGH GRADUALLY MOVES ACROSS THE SOUTHERN
ROCKIES BY TUESDAY, SOME LIGHT PRECIPITATION MAY LINGER, BUT THE
COLD AIRMASS OVER THE PLAINS MAY BE DEEP ENOUGH BY THIS TIME TO
SUPPRESS ANY RAIN OR SNOW TO THE SOUTH OVER TX/OK AND PERHAPS AS
FAR NORTH AS EXTREME SOUTHERN KANSAS. BUT AGAIN, WE ARE NOT
EXPECTING LARGE AMOUNTS OF PRECIPITATION. BY WEDNESDAY AND
THURSDAY, THE UPPER LEVEL TROUGH WILL BE PASSING ACROSS OK/TX. BY
THIS TIME, ANY LOW TO MID LEVEL BAROCLINICITY WILL BE GREATLY
DIMINISHED SO THAT PRECIPITATION IS NOT EXPECTED ACROSS WESTERN
KANSAS. BUT THIS TROUGH WILL DELAY THE ONSET OF ANY DOWNSLOPE
WARMING SO THAT TEMPERATURES WOULD REMAIN ON THE COOL SIDE OR
SLIGHTLY BELOW CLIMATOLOGY THROUGH THURSDAY.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 1200 AM CDT SAT MAR 30 2013

FORECAST CONCERN IS THE POSSIBILITY OF OVERNIGHT MVFR CIGS IN ASSOCIATION
WITH BR. DOWNSLOPE SOUTHWESTERLY WINDS EXPECTED BY 12Z, WHICH IS NOT
FAVORABLE FOR THE CONTINUATION OF FOG (IN FACT, SHOULD SCOUR IT OUT).
FRONT MOVES THROUGH TODAY WITH NORTHWESTERLY/NORTHERLY WINDS INCREASING
TO 15 KT IN THE WAKE OF THE DENSITY GRADIENT.
