THE UPR PATTERN INVOF NOAM IS HIGHLY AMPLIFIED...WITH UPR TROFS OVER THE EAST AND OFF THE BRITISH COLUMBIA COAST...AND STG RIDGING FM THE INTERMOUNTAIN WEST...NNEWD...ACRS THE CANADIAN PRAIRIES. THIS IS A VERY STABLE PATTERN...AND LITTLE CHG TO THE TROF AND RIDGE POSNS IS EXPECTED DURING THE FCST PERIOD. BUT A SLOW MODIFICATION OF THE COLD AIR IN THE ERN NOAM UPR TROF WL CAUSE THE FLOW ACRS THE ERN CONUS TO GRADUALLY WEAKEN.
