LATEST SURFACE ANALYSIS SHOWS A BOUNDARY EXTENDING THROUGH
NORTHERN MISSOURI INTO CENTRAL ILLINOIS INTO NORTHERN INDIANA.
MODELS INDICATE THIS FRONT WILL MEANDER IN THAT GENERAL VICINITY
OVER THE NEXT COUPLE OF DAYS AS AN UPPER LEVEL LOW SLOWLY DRIFTS
EAST FROM THE CENTRAL PLAINS TO OVER THE MIDDLE MISSISSIPPI
VALLEY. THIS WILL KEEP THE PAH FORECAST IN AN UNSTABLE PATTERN
THROUGH THE END OF THE WORK WEEK. MODELS ARE ALL OVER THE PLACE

TERM...WENT WITH CHANCE POPS DURING THE DAYTIME HOURS AND SLIGHT
CHANCE POPS OVERNIGHT.

AN UNSETTLED PATTERN IS EXPECTED TO PREVAIL THROUGH THE LONG TERM
PERIOD PRODUCING MULTIPLE CHANCES FOR SHOWERS AND THUNDERSTORMS.

THROUGH MOST OF THE PERIOD SURFACE SYNOPTIC FEATURES ARE HARD TO
COME BY WITH MOSTLY UPPER LEVEL INDUCED LIFT AS MULTIPLE WAVES OF
ENERGY PASS THROUGH THE FLOW. A WARM FRONT FORECAST TO BE JUST NORTH
OF OUR CWA ON SATURDAY IS SUPPOSED TO LIFT OFF TO THE NORTH KEEPING
US IN THE WARM SECTOR UNTIL A FRONTAL PASSAGE TUESDAY NIGHT INTO
WEDNESDAY.

MODELS BUILD AN H5 RIDGE OVER THE SOUTHWESTERN AND SOUTHERN SECTIONS
OF THE CWA SUNDAY... SUNDAY NIGHT...AND MONDAY WHICH SHOULD PRECLUDE
PRECIPITATION IN THOSE AREAS...OTHERWISE THERE ARE PRECIPITATION
CHANCES AREA WIDE THE REMAINDER OF THE LONG TERM PERIOD.

RIGHT NOW THE BEST CHANCES OF PRECIPITATION SHOULD BE TUESDAY NIGHT
INTO WEDNESDAY AS THE AFOREMENTIONED FRONTAL SYSTEM CROSSES THE
