...NO SVR TSTM AREAS FORECAST...

...NRN PLAINS/UPPER GRTLKS REGION...
THE HIGH AMPLITUDE UPPER FLOW REGIME WILL CONTINUE INTO THE WEEKEND.
 UPPER TROUGH ACROSS THE PAC NW WILL CONTINUE TO DIG SWD AS
STRONGEST PORTION OF THE JET REMAINS OVER THE EPAC THROUGH EARLY
SAT.  AS A RESULT...THE DOWNSTREAM RIDGE SHOULD REMAIN IN PLACE
ACROSS THE ERN PLAINS. THE SHORTWAVE TROUGH...NOW OVER CNTRL CA...
WILL BEGIN TO ACCELERATE NEWD TODAY/TONIGHT...THEN DAMPEN AS IT
GLANCES OFF THE UPPER RIDGE ACROSS THE NRN PLAINS/MANITOBA-SASK SAT
AFTN.  AT THE SURFACE...A LEE-TROUGH WILL BRIEFLY MIGRATE INTO PARTS
OF THE ERN DAKS AND CNTRL NEB SAT AFTN BEFORE RETREATING WWD IN WAKE
OF THE UPPER TROUGH PASSAGE.  A WARM FRONT WILL DEVELOP NEWD THROUGH
GRTLKS REGION WHILE A COLD FRONT SLOWLY MOVES SWD THROUGH THE NRN
HIGH PLAINS AND INTERMOUNTAIN WEST.

PERSISTENT SLY LOW-LEVEL FLOW WILL CONTINUE TO SUPPLY UPPER 50S TO
MID 60S DEW POINTS OVER ALL OF THE PLAINS BENEATH A STOUT EML
THROUGH SAT.  THIS WILL CONTRIBUTE TO MODEST POTENTIAL INSTABILITY
AHEAD OF THE WEAKENING UPPER IMPULSE/LEE-TROUGH.  BUT...IT APPEARS
THAT THE STRENGTH OF INHIBITION OVER MOST OF THE PLAINS WILL LESSEN
THE PROBABILITIES FOR SURFACE-BASED TSTMS.  GIVEN SUFFICIENT
HEATING...HOWEVER...THE THREAT FOR SURFACE-BASED INITIATION IS
NON-ZERO ACROSS PORTIONS OF THE CNTRL/ERN DAKS AND FAR NWRN MN LATE
SAT AFTN. GIVEN A PERSISTENT UPDRAFT...VERTICAL SHEAR WILL BE
SUFFICIENT FOR MAINLY MULTICELL STORMS WITH POSSIBLE HAIL/DAMAGING
WINDS.

OTHERWISE...ELEVATED TSTM CLUSTERS MAY CONTINUE TO DEVELOP ALONG THE
EDGE OF THE CAP THAT WILL DEVELOP NEWD INTO NWRN ONT/UPPER GRTLKS
REGION SAT-SAT NIGHT.  THOUGH A HIGHER ELEVATED HAIL THREAT WILL
REMAIN IN CANADA...A FEW STORMS MAY GRAZE U.S. PORTIONS OF THE LAKES
SUPERIOR/HURON AND ERN UPPER MI.
