   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 415 CONTINUES.
   
   A NEW WW WILL BE COORDINATED SOON BETWEEN THE SPC AND WFO/S ACROSS
   SOUTH CENTRAL/SERN NEB AND NRN/NERN KS.
   
   REGIONAL RADAR AND IR SATELLITE IMAGERY INDICATED A LARGE ONGOING
   MCC CENTERED OVER NORTH CENTRAL-NERN KS INTO SOUTH CENTRAL NEB. 
   THIS ACTIVITY HAS BEEN LOCATED ALONG AND GENERALLY N OF A
   QUASI-STATIONARY WARM FRONT WHICH AT 04Z EXTENDED FROM SWRN NEB INTO
   NWRN KS /W OF HLC/...AND THEN ESEWD TO RSL...SLN TO 25 NE EMP INTO
   WEST CENTRAL MO.  DESPITE RELATIVELY WEAK FORCING ALOFT...A BROAD
   40-50 KT SLY LLJ THROUGH CENTRAL KS WILL MAINTAIN AN ONGOING WAA
   REGIME ALONG AND N OF THE ABOVE MENTIONED WARM FRONT.  A MOIST AIR
   MASS EXISTS ACROSS THE AREA OF CONCERN /PW VALUES 1.5-2 INCH/.  THIS
   COMBINED WITH LATENT HEAT RELEASE WITHIN THIS EXTENSIVE STORM
   COMPLEX SUGGESTS THE THERMODYNAMIC PROFILE SHOULD REMAIN FAVORABLE
   FOR NEW TSTM DEVELOPMENT ALONG THE SWRN-SRN PERIPHERY OF THIS MCC. 
   MODERATE INSTABILITY AND EFFECTIVE BULK SHEAR AROUND 40 KT WILL
   MAINTAIN THE LIKELIHOOD FOR ORGANIZED STORMS WITH HAIL AND DAMAGING
   WINDS BEING THE PRIMARY THREATS.
   
   TRAINING STORMS WILL BE LIKELY FROM SOUTH CENTRAL NEB INTO NORTH
   CENTRAL TO NERN KS...WITH PRECIPITATION RATES /1-2 INCH PER HOUR/
   GIVEN THE HIGH PW VALUES.  AS THE LLJ VEERS TO SWLY OVERNIGHT...THE
   TSTM COMPLEX SHOULD SHIFT TOWARD THE ESE.
