AXIS OF VERY WEAK LIFT HAS EDGED INTO FAR SW PARTS OF THE AREA WITH
EARLIER RETURNS HAVING FALLEN APART AS IT ENCOUNTERED THE VERY DRY
LOW LEVELS. SLIGHTLY BETTER SETUP UPSTREAM FROM CHICAGO NW WHERE
SOME SPRINKLES/VERY LIGHT SHOWERS ARE OCCURRING FROM A MID LEVEL
DECK. HAVE LEFT THE INHERITED MENTION OF SPRINKLES INTO MON
MORNING IN SW AREAS, BUT TONED DOWN TO SLGT CHC FOR NOW. THESE
SHOULD QUICKLY END DURING THE MORNING WITH TEMPS BACK WELL INTO
THE 70S FOR THE AFTERNOON.
OUTSIDE OF THIS, A TRANQUIL AND SEASONABLY WARM FORECAST IS STILL IN
STORE UNTIL THE UPPER LEVEL FLOW BEGINS TO FLATTEN AND SFC HIGH
PRESSURE SHIFTS EAST TO ALLOW FOR INCREASING WARMTH AND MOISTURE,
ALONG WITH CHANCES FOR SHOWERS AND STORMS FOR THE WEEKEND.
