...NO TSTM AREAS FORECAST...
...SYNOPSIS/FORECAST...
MULTI-STREAM PATTERN WILL DEAMPLIFY SOMEWHAT OVER THE NEXT 24 HRS AS
HEIGHTS RISE OVER THE MID ATLANTIC REGION IN WAKE OF DEPARTING
TROUGH. DEEP NRN STREAM VORTEX NOW APPROACHING NW ONTARIO SHOULD
REMAIN WELL N OF THE CANADIAN BORDER AS IT CONTINUES SEWD. FARTHER
S...TWO MIDDLE STREAM DISTURBANCES WILL TRACK E ACROSS THE ERN
PACIFIC AND THE NRN GRT BASIN/NRN RCKYS...BOTH BETWEEN 40 AND 45 N.
POLAR OR MODIFIED POLAR AIR WILL PREVAIL AT LWR LVLS OVER MOST OF
THE NATION /ESPECIALLY E OF THE RCKYS/ IN WAKE OF COLD FRONT
CLEARING THE FL KEYS. WEAK INSTABILITY MAY LINGER OVER THE FL
STRAITS AND OFF THE SW FL CST N OF STALLING FRONT THROUGH THE
PERIOD. BUT RISK FOR ONSHORE THUNDER APPEARS TOO LOW TO WARRANT A
CATEGORICAL TSTM FCST.
