...NO TSTM AREAS FORECAST...

...SYNOPSIS AND DISCUSSION...

A SPLIT FLOW REGIME WILL BE MAINTAINED THROUGH THE D1 PERIOD WITH
THE PRIMARY FEATURE OF INTEREST BEING A MID AND UPPER-LEVEL LOW
WHICH WILL TRANSLATE FROM THE SRN ROCKIES INTO CNTRL/SRN PLAINS. IN
THE LOW LEVELS....A BROAD AREA OF HIGH PRESSURE FROM THE SRN PLAINS
INTO CNTRL/SRN APPALACHIANS WILL BUILD EWD WHILE A WEAK LEE
TROUGH/COLD FRONT PROGRESSES EWD THROUGH THE HIGH PLAINS.

FORCING FOR ASCENT ATTENDANT TO THE SUBTROPICAL BRANCH SYSTEM
MENTIONED ABOVE WILL PROMOTE SHOWER ACTIVITY ACROSS PORTIONS OF THE
SRN PLAINS INTO LOWER MS VALLEY DURING THE FORECAST PERIOD. WHILE
AN ISOLATED LIGHTNING STRIKE IS POSSIBLE...THE ENVIRONMENT IS
EXPECTED TO REMAIN TOO STABLE TO WARRANT INCLUSION OF A GENERAL TSTM
AREA.
