Area forecast discussion, Jan 29, 5:31 AM CST, 2 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
531 AM CST TUE JAN 29 2013

.AVIATION...12Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
A COLD FRONT WILL CONTINUE TO SINK SOUTHWARD ACROSS THE REGION
TODAY...WITH SHOWERS AND THUNDERSTORMS AFFECTING SOUTHEAST KANSAS
DURING THE DAYTIME HOURS. OTHERWISE THE UPPER LEVEL SYSTEM WILL MOVE
INTO THE REGION FOR LATER TODAY AND TONIGHT...WITH SNOW DEVELOPING
ACROSS CENTRAL/SOUTH CENTRAL KANSAS TONIGHT. THIS WILL CREATE POOR
AVIATION CONDITIONS AS THE CEILINGS/VISIBILITIES DROP INTO THE IFR
CATEGORY. THE SNOW SHOULD BEGIN TO TAPER OFF LATE TONIGHT WITH
SOME LIGHT SNOW ACCUMULATIONS EXPECTED OVER CENTRAL KANSAS.

JAKUB

.PREV DISCUSSION... /ISSUED 453 AM CST TUE JAN 29 2013/

UPDATE...
STRONG COLD FRONT CONTINUES TO DROP SOUTHEAST A BIT FASTER THAN
EXPECTED AND CURRENTLY MOVING THRU THE WICHITA METRO AREA. AT
THE SAME TIME...CONVECTION CONTINUES TO BLOSSOM FROM THE
SOUTHEAST CORNER OF KANSAS INTO CENTRAL OKLAHOMA. PERIODIC
TWEAKS TO THE FORECAST WILL NO DOUBT BE NEEDED THROUGH THE
MORNING TO REFRESH GRIDS ALONG THE SHARP BOUNDARY.

KED

PREV DISCUSSION... /ISSUED 325 AM CST TUE JAN 29 2013/

DISCUSSION...
FORECAST CONCERNS...FRONTAL MOVEMENT/TIMING TODAY AND THEN
SNOW CHANCES AND POTENTIAL ACCUMS FOR CENTRAL KANSAS TONIGHT.

TODAY-TONIGHT
LATEST SHORT TERM MODELS ARE MORE NOTICEABLY BULLISH ON POST
FRONTAL QPF AND LIGHT SNOW ACCUMS ACROSS CENTRAL AS THE UPPER
TROF LIFTS NORTHEAST ACROSS THE AREA EARLY TONIGHT. IN THE
MEANTIME...STRONG SURFACE COLD FRONT HAS SLIPPED SOUTH ACROSS
CENTRAL KANSAS EARLY THIS MORNING. TEMPERATURE FORECAST A BIG
CHALLENGE TODAY HINGING ON FRONTAL TIMING...MAINLY ACROSS THE
MID-PORTION OF THE AREA INCLUDING GREATER WICHITA. FRONT APPEARS
A BIT FASTER THAN EARLIER PROGGED...SO A SLIGHT TWEAK TO THE
PREVIOUS FORECAST/TRENDS NEEDED...WITH NON-DIURNAL OR FALLING
TREND FOR SOUTHERN AREAS TODAY. A PERIOD OF STRONG TO MARGINALLY
SEVERE CONVECTION REMAINS POSSIBLE ACROSS SOUTHEAST KANSAS EARLY
TODAY BEFORE THE BETTER MOISTURE/INSTABILITY AXIS GETS SHUNTED
EAST AS THE FRONT SLIDES IN LATER THIS AFTERNOON. AS THE MAIN
UPPER TROF AND PV ANOMALY MOVES NORTHEAST ACROSS THE AREA LATE
THIS AFTERNOON AND EVENING A PERIOD OF POST-FRONTAL PRECIP IS
EXPECTED...WITH THERMAL PROFILES SUPPORTING A TRANSITIONAL MIX
TO SNOW ACROSS CENTRAL KANSAS. CONFIDENCE ON AMOUNTS IS MODEST
AT BEST...THOUGH AN INCH OR TWO OF SNOW IS POSSIBLE NORTH OF
HIGHWAY 50...MAINLY JUST AFTER DARK THROUGH ABOUT MIDNIGHT. IF
CONFIDENCE INCREASES WITH LATER MODEL RUNS THE DAY SHIFT MAY
NEED TO ISSUE A LOW GRADE WINTER WEATHER ADVISORY.

WEDNESDAY-THURSDAY
THESE LOOK TO BE THE COLDEST DAYS OF THE FORECAST PERIOD AS
A RATHER IMPRESSIVE MEAN LONGWAVE UPPER TROF TRANSITIONS FROM
THE MIDWEST ACROSS THE EASTERN CONUS. ADDITIONAL SHORTWAVES
WITHIN THE MEAN FLOW WILL SEND A REINFORCING SHOT OF COLDER
AIR ACROSS THE AREA LATE THURSDAY.

FRIDAY-MONDAY
LITTLE CHANGE TO THE OUTER PERIODS OF THE FORECAST WITH A
GRADUAL MODERATING TREND AS THE AMPLITUDE AND BREADTH OF THE
EASTERN CONUS LONGWAVE TROF DAMPENS A BIT AND SHIFTS EAST
THRU TIME.
