AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO
315 PM CST MON FEB 9 1998

FCST CHALLENGES LOOK TO BE MOSTLY TOWARD END OF UPCOMING PCPN EVENT
AS FIRST PERIOD RELATIVELY SIMPLE.  PCPN SHIELD ALREADY AFFECTING
SWRN ZONES AND REALLY ONLY TWO MINOR THINGS TO CONSIDER.
FIRST...TIMING.  MAY TAKE 3-5 HOURS AFTER ZONE ISSUANCE FOR NERN
ZONES TO SEE RA BUT WILL ALLOW STF TO HANDLE ONSET.  ALSO A BIT
CONCERNED ABOUT LACK OF REDEVELOPMENT BEHIND FIRST BAND WHICH MAY
GIVE A LULL IN PCPN BUT THINK WILL FILL IN LATER TO JUSTIFY OCNL
WORDING.  SECOND...THUNDER.  MID-LVL LAPSE RATES NEARLY MOIST
ADIABATIC BUT WITH FORCING NOT THAT STRONG WILL LEAVE THUNDER OUT
EVEN THOUGH MIGHT GET A RUMBLE OR TWO.

QUESTION IN 2ND AND 3RD PERIODS IS WHETHER NRN ZONES CAN SWITCH OVER
OR NOT.  PARTIAL THICKNESSES AND FCST SOUNDINGS SUGGEST MOST PCPN
SHD BE LIQUID UNTIL AFT 00Z WED.  WK FRONT PUSHING INTO NRN NEB DOES
HAVE SOME COLD AIR BEHIND IT BUT WILL HAVE TO GET SFC LOW TO OUR
EAST TO SWITCH WAA BACK TO CAA.  HAVE MY DOUBTS SWITCHOVER CAN OCCUR
DURING AFTN AS PER CURRENT FCST BUT SINCE IT WILL BE CLOSE WILL
LEAVE IN FOR NOW.  WILL LEAVE ANY MENTION OF -SN OUT OF KC FOR NOW.

PCPN TUE NIGHT SHD BE LIGHT WITH FORCING WEAK AT BEST.  HWVR...
SINCE MODELS MAY BE A TAD FAST IN MOVING SYS OUT AND DEFORMATION
ZONE MAY BE MORE SIGNIFICANT THAN ADVERTISED...DONT WANT TO BE
TRIMMING POPS JUST YET.  REMAINDER OF FCST LOOKS TO BE IN GOOD SHAPE
WITH EXCEPTION OF TEMPS IN E ON WED WHERE WILL HAVE TO TRIM HIGHS
SOME.

AVN SHOWING THAT PCPN COULD RETURN AS SOON AS THU NIGHT BUT WILL
LEAVE AS FRI FOR NOW.

.EAX...
MO...NONE.
KS...NONE.
