CURRENTLY RW/TRW LOCATED OVR A LARGE PORTION OF NE MT. HAVE HAD
SEVERAL SVR TRWS THIS EVENING. CURRENTLY HAVE A SVR TRW OVR MALTA
AND ONE MVG INTO SWRN VALLEY CO...HOWEVER THESE ARE ISOLATED AND
PROBABLY DON/T WARRANT EXTENDING THE WATCH. STRONGEST CELLS ARE MVG
INTO WRN ND...AND SELS IDEA OF LETTING THE WATCH EXPIRE LOOKS GUD TO
ME. NE MT WILL PROBABLY SEE RW/TRW EXTENDING THRU THE NIGHT WITH
ISOLATED SVR NEAR TRWS THAT FORM ALONG OUTFLOW BNDRYS. CURRENT
ZONE PACKAGE LOOKS OK...BUT WILL NEED TO UPDATE TO TAKE OUT SVR TRW
WATCH...AND WILL STILL MENTION A FEW ISOLATED SVR THROUGHOUT THJE
NIGHT. WL COORDINATE WITH GTF BY TELCON TO DISCUSS HOW WE WILL HANDLE
CURRENT WATCH SITUATION.
