LOOPS SHOW THAT UPR LOW WAS CENTERED OVR SERN KS. A FEW RETURNS
INDCD ON THE 88D ACRS NWRN AND SERN PARTS OF THE FA ATTM.

DUE TO NCEP COMPUTER PROBLEMS...AVN JUST COMING IN. MODELS SEEMED TO
INTIALIZE UPR LOW POSITION FAIRLY WELL. BASIC TREND IS FOR UPR SYS
TO DRIFT ACRS CNTRL MO TODAY AND THE SLIDE EAST OF THE REGION LATE
TNGT AND WED. UPR HI NORTH OF THE GREAT LAKES WL TEND TO KEEP UPR
