AN UPPER LEVEL TROUGH IS CURRENTLY MOVING EAST ACROSS THE GREAT
LAKES REGION WITH THE BASE EXTENDING SOUTH TO AROUND TENNESSEE. A
PLUME OF HIGHER ATMOSPHERIC MOISTURE CONTENT STRETCHES FROM THE
NORTH-CENTRAL GULF TO AROUND THE APEX OF THAT TROUGH. LOCALLY, ITS A
FAIRLY SHARP GRADIENT FROM WEST TO EAST OF THAT HIGHER THETA-E AND
CAN SEE THAT SAME THING VIA RADAR IMAGERY. SEA BREEZE BOUNDARIES
WILL BE FOCUS FOR AREAS OF CONVECTION BUT LACK OF LARGE SCALE
FORCING WILL KEEP ACTIVITY FROM BECOMING TOO STRONG. CAMS AND GLOBAL
MODELS ARE IN GOOD AGREEMENT THAT BY AROUND 00Z, SHOWERS WILL FIZZLE
OUT. FOG POTENTIAL WILL NEED TO BE MONITORED AGAIN TONIGHT.
