Area forecast discussion, Jan 7, 3:58 PM CST, 8 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
358 PM CST MON JAN 7 2008

.DISCUSSION...

INTERESTING FORECAST FOR TONIGHT AND TUESDAY. LATEST WATER VAPOR
LOOP AND PROFILERS SHOW A 70 KT JET AT 500 MB ACROSS OKLAHOMA ACROSS
SOUTHEAST KANSAS INTO SOUTHWEST MISSOURI THIS AFTERNOON. BROAD UPPER
TROUGH WAS OVER THE WESTERN STATES WITH A SERIES OF SHORTWAVES
ROTATING THROUGH THE TROUGH AND AIMING FOR THE PLAINS. FRONTAL
BOUNDARY HAS MOVED BACK SOUTH A LITTLE THIS AFTERNOON WITH THE FRONT
AT 21Z ROUGHLY FROM NEAR LAWRENCE TO NEWTON.

LATEST MESO ANALYSIS SHOWS MUCAPES OF 500 J/KG ACROSS EAST CENTRAL
KANSAS. MOST OF THE CONVECTIVE ACTIVITY HAS DEVELOPED SOUTHEAST OF
THE CWA THIS AFTERNOON. WILL KEEP A CHANCE FOR THUNDERSTORMS THIS
EVENING ACROSS EAST CENTRAL KANSAS WITH FRONT IN THE AREA AND
ANOTHER SHORTWAVE EJECTING NORTHEAST FROM NEW MEXICO THIS EVENING. A
STRONGER WAVE MOVES OUT OVERNIGHT AND DEVELOPS A SURFACE LOW ALONG
THE FRONT IN THE PANHANDLE THEN IT RIDES THE FRONT NORTHEAST INTO
ILLINOIS BY 12Z TUESDAY. AMOUNT COLD AIR BEHIND THE FRONT IS STILL A
QUESTION MARK AS TO HOW COOL THE LAYER THICKNESS PROFILES WILL GET
FOR A CHANGE OVER TO SNOW TONIGHT ACROSS NORTH CENTRAL KANSAS. TOOK
A COMBINATION OF THE ECMWF...UKMET AND GFS THERMAL PROFILES FOR
TONIGHT. A DEFORMATION ZONE WILL FORM LATE TONIGHT ACROSS EAST
CENTRAL BACK INTO CENTRAL KANSAS WITH STRIPE OF ACCUMULATING SNOW
POSSIBLE AROUND AN INCH OR SO. WENT WITH A MIX OF RAIN AND SNOW
AFTER MIDNIGHT ACROSS NORTHEAST KANSAS AND RAIN SOUTH OF THE
TURNPIKE. LOWS TONIGHT WILL DROP DOWN TO AROUND FREEZING IN
NORTHEAST KANSAS WITH UPPER 30S SOUTHEAST OF I-35.

FOR TUESDAY THE FORCING WITH THE UPPER TROUGH WILL MOVE EAST BY LATE
MORNING OR EARLY AFTERNOON. THERMAL PROFILES SUGGEST RAIN AND SNOW
WITH A CHANGE TO ALL SNOW IN PARTS OF NORTHEAST KANSAS BY 15Z.
TEMPERATURES MODIFY IN THE AFTERNOON WITH DECREASING CLOUDS. HIGHS
IN THE LOW TO MID 40S STILL LOOK ON TRACK.

FOR TUESDAY NIGHT THROUGH THURSDAY...SHORTWAVE TROUGH MOVING ACROSS
THE MIDDLE MISSISSIPPI VALLEY TUESDAY EVENING WILL HAVE CONSIDERABLE
SUBSIDENCE BEHIND IT AND CLEARING SKIES.  SURFACE RIDGE THEN MOVES
EWD ACROSS ERN KS TUESDAY NIGHT WITH LIGHTER WINDS.  WINDS THEN TURN
SOUTHERLY ON WEDNESDAY AHEAD OF NEXT SHORTWAVE THAT WILL AFFECT AREA
WEDNESDAY NIGHT INTO THURSDAY.  BOTH NAM AND GFS INTENSIFY THIS
SYSTEM WED NIGHT...WITH BOTH SIMILAR IN MANY FEATURES.
GFS...HOWEVER...HAS CONSIDERABLY MORE QPF ASSOCIATED WITH IT. 12Z
ECMWF COMES IN SIMILAR TO NAM WITH MAIN QPF DEVELOPING EAST OF AREA.
THIS SEEMS PLAUSIBLE AND HAVE GONE WITH THIS MORE CONSERVATIVE
FCST.  THUS...HAVE UPPED POPS ONLY A LITTLE FROM GOING FCST.  PRECIP
TYPE OF SOME DEBATE AS TEMPERATURE PROFILES AT START OF PRECIP
CHANCES WED NIGHT WARM ENOUGH FOR RAIN.  HOWEVER...THICKNESSES
RAPIDLY DROP AS DYNAMIC COOLING TAKES PLACE DURING SYSTEM
INTENSIFICATION.  THUS...HAVE INDICATED MOSTLY SNOW CHANCES FOR
LATER WEDNESDAY NIGHT AND THURSDAY...EVEN THOUGH THE CHANCES FOR
ANYTHING MEASURABLE WILL BE LOW.

THE LONG LONG TERM...FRI-MON...MAIN FEATURES CONTINUE TO BE A
EASTERN PACIFIC RIDGE...AND LONGWAVE TROUGH OVER THE CENTRAL AND
EASTERN UNITED STATES. LOCAL AREA TO REMAIN UNDER NORTHWESTERLY FLOW
THROUGH THE PERIOD. SEVERAL SHORTWAVES WORK THEIR WAY THROUGH THE
FLOW REGIME...AND LONG RANGE MODELS FAIRLY CONSISTENT WITH ONE
ANOTHER HANDLING THE NUMBER OF WAVES EMBEDDED IN THE MEAN FLOW. WEAK
COLD FRONTS WILL ALSO SLIP ACROSS THE LOCAL AREA DURING THIS TIME
FRAME. BUT...PERSISTENT NORTHWESTERLY FLOW BOTH ALOFT AND AT THE
SURFACE WITH LITTLE CHANCE FOR MOISTURE RETURN BETWEEN FRONTAL
PASSAGES...AND CONSISTENT DEPICTION OF BEST LARGE SCALE LIFT TO DROP
SOUTH OF THE LOCAL AREA...HAVE MAINTAINED DRY FORECAST. WEAK COLD
PUSH TO SLIDE IN BEHIND EACH OF THE WEAK FRONTS...AND HAVE COOLED
GOING TEMPERATURES BY A DEGREE OR TWO...BUT CONTINUE TO EXPECT NEAR
NORMAL READINGS THROUGH THE PERIOD.

KONOP

.AVIATION...

VFR CONDITIONS WILL CONTINUE THROUGH 08Z TONIGHT WITH MVFR CIGS AND
VSBYS WITH RAIN DEVELOPING IN THE 08Z-11Z PERIOD. BEYOND 11Z
WIDESPREAD MVFR WITH ISOLD IFR CIGS AND VSBYS WITH SNOW AND RAIN ARE
EXPECTED THROUGH 17Z. FRONT HAS MOVED SOUTH OF KTOP AND KFOE SO
