SUNDAY/S GRT BASIN IMPULSE WILL CUT-OFF INTO A LOW AND SLOWLY
TRANSLATE SWD INTO NRN MEXICO AS A MEAN-LAYERED RIDGE BUILDS ACROSS
THE WCOAST ON MONDAY. MEANWHILE...THE SUB-TROPICAL JET STREAM WILL
REMAIN A PROMINENT FEATURE...STRETCHING FROM THE TROPICAL PACIFIC TO
THE SERN STATES. THIS JET WILL CONVERGE WITH THE NRN BRANCH JET
OVER THE MID-ATLANTIC...WITH BUILDING PRESSURES AT THE SFC. THIS
WILL EFFECTIVELY FORCE A COLD FRONT SWD INTO NRN FL AND THE NRN GULF
BASIN. FLOW ALONG/AHEAD OF THE FRONT WILL LIKELY VEER TO

AS A RESULT...ORGANIZED SVR TSTMS ARE NOT ANTICIPATED ESPECIALLY
GIVEN THE ANTICIPATED POOR LAPSE RATE ENVIRONMENT.
