...SYNOPSIS...
WELL-ESTABLISHED NWLY MID LEVEL FLOW REGIME WILL DOMINATE MUCH OF
THE CONUS THIS PERIOD IN THE WAKE OF DEPARTING EAST COAST TROUGH AND
POLAR FRONT PASSAGE. MEANWHILE...A BROAD UPPER LEVEL RIDGE AND
WIDESPREAD SUBSIDENCE WILL COVER MUCH OF THE WRN U.S....AND EXTEND
NEWD ACROSS THE GREAT PLAINS TO THE UPPER MS VALLEY. A STRONG
PACIFIC SHORT WAVE TROUGH IS FCST TO CREST WRN NORTH AMERICAN RIDGE
AXIS AND THEN ADVANCE RAPIDLY SEWD ACROSS THE CANADIAN ROCKIES ON
SATURDAY. SIGNIFICANT HEIGHT FALLS AND INTENSIFYING DEEP LAYER WIND
FIELDS WILL ACCOMPANY THIS DISTURBANCE FROM THE NRN ROCKIES TO THE
NRN PLAINS THROUGH SATURDAY NIGHT AS ASSOCIATED SURFACE CYCLONE
DEEPENS NORTH OF LAKE SUPERIOR.

MODEST TO STRONG UPWARD VERTICAL MOTION WILL EXIST WITH BOTH THE
DEPARTING EAST COAST TROUGH/LOW ACROSS NEW ENGLAND...AND AHEAD OF
THE DIGGING TROUGH FROM THE ROCKIES NRN PLAINS LATE IN THE PERIOD.
HOWEVER...LACK OF SUFFICIENT LOW LEVEL MOISTURE AND/OR GENERALLY
COLD BOUNDARY LAYER AIR MASS SHOULD RESTRICT TSTM DEVELOPMENT FOR
THE FIRST HALF OF THE WEEKEND.
