WITH NONE OF THE 00Z MDLS SHOWING QPF FOR THE CURRENT TSTMS IN NERN
AND CNTRL SD...HOW MUCH STOCK DO YOU PUT IN THEM FOR THE REST OF THE
FCST? MDLS HAVE HAD A DIFFICULT TIME WITH THE CURRENT PATTERN THE
PAST FEW DAYS AND WL ONCE AGAIN NEED TO BROAD BRUSH POPS AFT THIS
MRNGS TSTMS DISSIPATE. LUCKILY MDLS ARE IN BETTER AGREEMENT THAN
PAST DAYS FOR THE FIRST 36 HRS WITH TIMING THE MAIN FCST CHALLENGE.
HAVE SIDED WITH THE DETAILS PROVIDED BY THE ETA...BUT LIKE THE
TIMING THE NGM/AVN PROVIDED WHICH ARE ABT 6 HRS SLOWER THAN THE ETA.

ALL 3 MDLS SHOW A MID-LVL VORT MAX MOVING FM THE NEB PANHANDLE
THROUGH SCNTRL SD INTO ERN SD. AM SOMEWHAT SUSPICICOUS OF THIS
FEATURE...BUT 06Z RUC CONTINUE THE TREND. WITH PLENTY OF
MOISTURE...INSTABILITY...AND BOUNDARIES FOR FOCUS...SCT TSTMS REMAIN
IN THE FCST FOR THIS AFTN INTO TNGT. MAIN FOCUS OF ACTIVITY SHOULD
HOLD FOR THIS EVE/TNGT...BUT COULD START EARLIER DURING THE AFTN IN
SCNTRL SD. ALL 3 MDLS SUGGEST MOST OF THE PCPN SHOULD BE CONFINED TO
FAR ERN CWA AND HAVE REMOVED POPS IN WRN/CNTRL CWA FOR THU.

FOR TEMPS...HI HUMIDITY HAS SEEMED TO KEEP AFTN TEMPS FM RISING AS
HIGH AS POTENTIAL WOULD SUGGEST. OVERALL WENT WITH A COMPROMISE OF
THE VARIOUS GUIDANCES...WITH A SLIGHT COOL BIAS THAT LEANS TOWARD THE
COOLER FWC.
