TSTMS PULSING THIS AFTN BETWEEN PARK RAPIDS AND DULUTH. THEY'RE
FIRING ON THE N SIDE OF THE INSTABILITY AXIS. A FEW MORE ARE
REGENERATING IN ERN ND, BUT THEY SHOULD DIE AS THE SUN GOES DOWN.
WE'LL LEAVE A LOW POP IN NWRN WI EARLY. THEN CALL FOR SLOW CLEARING.

ON SUNDAY, ZONAL FLOW SENDING THRU A COUPLE OF IMPULSES AT DIFFERENT
TIMES. ONE WILL MOVE THROUGH SRN SECTIONS DURING THE AFTN, BUT ONE
ALONG THE CANADIAN BORDER WILL WAIT UNTIL ALMOST EVENING.

ETA/MESOETA HAVE A CONSITENT HANDLE ON TOPICS AND WILL FOLLOW THE
ETA FOR DETAILS. NGM REALLY TAKES OFF ON ITS OWN INDEPENDENT TRACK
FOR EMONDAY WITH TEMPS 8 TO 12 DEG ABOVE THE MAV AND FAN. WILL TRIM
BACK FROM THAT, BUT BELIEVE THE MAV IS TOO COOL BASED ON HOW IT
PERFORMED FOR OUR CWA TODAY.
