...SYNOPSIS/FORECAST...
A PROGRESSIVE FLOW PATTERN IS EXPECTED ACROSS THE U.S. ON FRIDAY AS
A STRONG MID/UPPER LEVEL PACIFIC JET TRANSLATES EWD ACROSS WRN
CANADA AND THE NWRN STATES. THIS WILL RESULT IN HEIGHT RISES
DOWNSTREAM ACROSS THE CENTRAL U.S. TO THE GREAT LAKES AND SERN
STATES...WHILE AN UPPER TROUGH PROGRESSES EWD REACHING THE ERN
SEABOARD BY 12Z SATURDAY. IN THE WAKE OF THE ERN TROUGH...A
BUILDING SURFACE HIGH WILL FORCE A COLD FRONT WELL INTO THE GULF OF
MEXICO AND THROUGH THE SRN HALF OF FL BY FRIDAY AFTERNOON. BANDS OF
CONVECTION ARE EXPECTED TO ACCOMPANY THE FRONT...BUT A WARM LAYER AT
MID LEVELS AND MODEST LOW LEVEL MOISTURE WILL PRECLUDE DEEP MOIST
CONVECTION/TSTM POTENTIAL.
