...SYNOPSIS/FORECAST...
TWO-STREAM...WEAKLY PHASED FLOW REGIME WILL CONTINUE THIS WEEKEND
WITH SRN STREAM WAVE TRAIN PRESERVING A GENERAL LARGE-SCALE TROUGH
OVER THE ERN TWO-THIRDS OF THE COUNTRY. WAVE CURRENTLY DIGGING INTO
THE MID-SOUTH WILL ADVANCE TO OFF THE ATLANTIC SEABOARD BY TONIGHT.
THIS WILL FORCE THE LINGERING COLD FRONT OVER SRN FL INTO THE
BAHAMAS AND CUBA LATER TODAY.

GENERALLY STABLE OFFSHORE FLOW WILL PRECLUDE THUNDERSTORMS ACROSS
THE COUNTRY...WITH THE HIGHEST PROBABILITIES OVER THE GULF STREAM
AND FL STRAITS.
