255 PM EDT SUN JUN 3 2001

STATIONARY FRONT ACROSS FAR NORTH PART OF CWA THIS AFTERNOON.
VERY UNSTABLE AIR GIVING PULSE STORMS OVER THE NORTH AND WEST PART
OF CWA ATTM.

MODELS IN GOOD AGREEMENT SHOWING THE 500MB CLOSED LOW ROTATING OUT
OF THE SOUTHERN GREAT LAKES INTO SOUTHEAST CANADA OVER THE NEXT 2
DAYS. SECOND UPPER LOW DROPS INTO PACIFIC NORTHWEST AND ROTATES
SOUTHEAST THEN NORTHEAST TO THE CANADIAN BORDER. THIS PRODUCES WEAK
RIDGING IN THE MIDDLE PART OF THE COUNTRY...AND THE BERMUDA HIGH
BUILDS INTO THE SOUTHEAST STATES.

AT THE SURFACE...THE STATIONARY FRONT OVER EXTREME NORTH GEORGIA
LIFTS NORTH TONIGHT IN RESPONSE TO THE UPPER LOW OVER THE GREAT
LAKES MOVING NORTHEAST AND THE BUILDING BERMUDA HIGH. MOISTURE
MOVING SOUTHEAST WITH THE TSTM COMPLEX COVERS CWA BY THIS
EVENING...THEN LIFTS NORTH WITH THE WARM FRONT ON MONDAY. REALLY
GOOD SURGE OF GULF MOISTURE SPREADS INTO THE SOUTHERN AND WEST PART
OF CWA BY MONDAY EVENING. UPPER SUPPORT BECOMES MORE ORGANIZED
TUESDAY IN THE MISSISSIPPI/LOUISIANA AREA...BUT A COUPLE OF OTHER
IMPULSES MOVE INTO THE CWA IN THE SOUTHERLY FLOW PATTERN. THIS WILL
INCREASE THE POPS ON DAY 2.

FORECAST WILL CONTINUE THE PRESENT TREND OF SLIGHT CHANCE TO CHANCE
POPS EACH PERIOD...AND INCREASING TO LIKELY CATEGORY TUESDAY AS
THE ORGANIZED UPPER SUPPORT ARRIVES INTO THE AREA. IN THE NEAR
TERM...WILL TAKE A LOOK AT RADAR TO GET A FEEL FOR FIRST PERIOD
POPS. FOR TEMPS...EXPECT WARMER TEMPS ON MONDAY WITH THE DECREASE IN
CLOUDS AS THE WARM FRONT LIFTS NORTH AND AHEAD OF THE SURGE OF GULF
MOISTURE. DAY 2 HIGHS WILL BE LOWER WITH THE INCREASE IN CLOUDS.
