NEXT UPPER WAVE EJECTING OUT OF THE ROCKIES NOTED IN WATER VAPOR IMAGERY IS COMBINING WITH LEE SIDE TROF OF WARM FRONT TO FIRE CONVECTION EAST OF THE ROCKIES INTO WRN NE AND ERN WY. LATEST RUC SHOWS WARM FRONT EDGING NORTH OVERNIGHT WITH SHORT WAVE AND ASSOCIATED MID LVL OMEGA DRIFTING INTO THE CENTRAL/NORTHERN PLAINS THROUGH THE OVERNIGHT HOURS.

WILL UPDATE AGAIN TO CLEAN UP PCPN WORDING AND REMOVE EARLY ACTIVITY FROM MOST AREAS TO CONCENTRATE ONLY ON OVERNIGHT ACTIVITY. .ABR...NONE. FAUCETTE
