Area forecast discussion, Sep 22, 2:35 PM CDT, 3 hours 10 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
235 PM CDT FRI SEP 22 2000

...MAIN FORECAST PROBLEM IS RAIN CHANCES IN THE COLD AIR...

WSR-88D SHOWING FRONT FROM ABILENE TO SENECA AT 1930Z.  FRONT IS ONLY
MAKING VERY SLOW PROGRESS SOUTHEAST.  19Z LAPS DATA SUGGESTS CAP HAD
BEEN ERODED ACROSS NORTHEAST KANSAS AHEAD OF THE FRONT...WITH CAPES
RUNNING 2000-2500 J/KG.  WOULD EXPECT STORMS TO FIRE SHORTLY AHEAD
OF FRONT.  18Z HILLSBORO HODOGRAPH SHOWED GOOD STORM RELATIVE INFLOW
WITH SOME TURNING...SO SEVERE STORMS ARE POSSIBLE THIS EVENING AHEAD
OF THE FRONT.

STRATUS ACROSS NEBRASKA SHOULD SPREAD RAPIDLY SOUTHEAST AFTER DARK
AND OVERSPREAD NORTH CENTRAL KANSAS.  PROFILERS INDICATE FRONT IS
VERY SHALLOW...SO SHOULD SEE OVERRUNNING RAIN BREAK OUT BEHIND THE
FRONT THIS EVENING.

MAIN QUESTION AFTER TONIGHT IS THE EXTENT OF THE OVERRUNNING
PRECIPITATION BEHIND THE COLD FRONT.  FRONT REMAINS QUITE SHALLOW
THROUGH SUNDAY MORNING...WITH GOOD SOUTHWEST FLOW ABOVE IT.  THINK
THERE WILL BE SOME LIGHT RAIN BREAK OUT BEHIND THE FRONT AS THE MAIN
UPPER SYSTEM SLOWLY EJECTS.  Q-VECTORS SUGGEST FAR EAST CENTRAL
KANSAS WILL HAVE THE BEST CHANCE FOR RAIN...WITH SATURDAY NIGHT
BEING THE FAVORED TIME PERIOD.  CARRY CHANCE POPS SATURDAY...
SATURDAY NIGHT AND SUNDAY...WITH THE HIGHEST POPS IN THE SOUTHEAST
ZONES.

TEMPERATURES TO BE TRICKY AS SHALLOW COLD AIR MASS IS DIFFICULT FOR
THE MODELS TO HANDLE.  WILL PRETTY MUCH FOLLOW THE ETA 2 METER
TEMPERATURES AS THE ETA IS THE BEST IN HANDLING THE SHALLOW COLD AIR
MASSES.

.TOP...NONE.
