.PREV DISCUSSION...

FORECAST FOCUS IS ON THREAT FOR TSRA TONIGHT AND THURSDAY.

NEAR 18Z STATIONARY FRONT EXTENDED FROM MINNESOTA SOUTHEAST INTO
FAR NORTHERN OHIO. FORECAST AREA /FA/ WAS UNDER INFLUENCE OF WEAK
HIGH PRESSURE.

MODELS IN DECENT AGREEMENT THIS RUN. WILL USE A BLEND.

MCS DEVELOPMENT EXPECTED TONIGHT ACROSS MN AND WI IN STRONG WARM
ADVECTION REGIME ALOFT. THICKNESS PROGS AIM THIS COMPLEX INTO NORTHERN
INDIANA...AND WARM ADVECTION FOCUS SHIFTS INTO SAME AREA BY
MORNING. MOST OF RAIN SHOULD STAY TO THE NORTH OF THE FA...BUT
FEEL ENOUGH OF A THREAT EXISTS ACROSS THE FAR NORTHERN FA TO KEEP
CURRENT SLIGHT CHANCE POPS IN TONIGHT. CLOUDS FROM MCS WILL HELP
KEEP TEMPERATURES UP A BIT MORE THAN PREVIOUS NIGHTS ACROSS THE
NORTHERN FA...BUT SOUTHERN HALF OF FA WILL STILL SEE DECENT
RADIATIONAL COOLNIG OVERNIGHT. MAV GUIDANCE REFLECTS THIS
SCENARIO WELL AND WILL THUS GO CLOSE TO THESE NUMBERS.

ON THURSDAY...MCS COULD STILL BE ACROSS FAR NORTHERN INDIANA
THROUGH THE MORNING...SO WILL EXTEND THE SLIGHT CHANCE POPS
THROUGH THEN. BOUNDARY WILL THEN RETREAT BACK TO THE NORTHEAST AS
UPPER RIDGE BUILDS BACK NORTH. THUS EXPECT A DRY AFTERNOON ACROSS
THE ENTIRE FA. MORE CLOUDS WILL KEEP NORTHEAST FA COOLER THAN
REMAINDER OF FA. MAV TEMPS ARE BEST MOST AREAS...BUT MAV LOOKS A
BIT WARM ACROSS THE FAR SOUTHWEST GIVEN EXPECTED 850 TEMPS. MAV IS
ALSO A LITTLE WARM ACROSS THE NORTHWEST GIVEN EXPECTED CLOUD COVER.

DRY WEATHER WILL THEN CONTINUE INTO FRIDAY NIGHT AS UPPER RIDGE
KEEPS SYSTEMS AT BAY. FRONT APPROACHES THE AREA ON SATURDAY AND
MOVES IN ON SUNDAY. WILL DROP POPS TO SLIGHT CHANCE CATEGORY
ON SATURDAY WITH LITTLE IN THE WAY OF FORCING. HAVE EXTENDED
CHANCES INTO SUNDAY NIGHT DUE AS FRONT LOOKS TO MOVE SLOWER THAN
PREVIOUSLY THOUGHT.
