.DISCUSSION...
FRONTAL BOUNDARY CURRENTLY IN NRN MO AND SAGGING SWD WITH
NELY FLOW AND MDT PRES RISES TO THE NORTH. BLOCKY PATTERN
PERSISTS OVER ALASKA/NWRN CANADA WITH UNSEASONABLY STG
S/W ROTATING S FROM THE ARCTIC THROUGH SASKATCHEWAN AND
THEN CURLS EWD THROUGH SRN CANADA. SFC HIGH OVER THE ROCKIES
SPREADS OUT ACROSS NRN PLAINS INTO THE GREAT LAKES OFFERING
A WINDING FRONTAL BOUNDARY THAT SHOULD HOLD THROUGH EARLY TO
MID WEEK NEXT WEEK.

LOOK FOR CONVECTION/FROPA TO COMBINE TO HOLD TEMPS SVRL
DEGREES BELOW PREVIOUS DAYS AND HAVE INSTILLED MDT/HIGH
POPS FOR SEVERAL PERIODS.  ANTECEDANT DRY COND KEEP ME
FROM NOTING ANY HIGHLIGHTS BUT I THINK PRECIP WILL BECOME
MORE FOCUSED AND ORGANIZED OVER THE NEXT COUPLE OR THREE
DAYS AND WILL MENT LCL HVY AMOUNTS AT TIMES.

PRECIPITABLE WATER VALUES BECOME QUITE HIGH AND PCPN ACTIVITY
WILL BE VERY EFFICIENT SO WILL NEED TO KEEP A CLOSE EYE ON
ACTIVITY THROUGH THE NEXT 3-5 DAYS. RELATIVE GOT 1.75 THIS
EVENING NEAR ST. PAUL....35 MI NW OF ST LOUIS IN A DOWNPOUR
THERE.

SVRL S/W COULD ROTATE THROUGH THIS TROF THROUGH THE AREA AND IT
COULD GET INTERESTING BFORE ALL THIS ENDS.  MUST KEEP A CLOSE
WEATHER WATCH ON THIS W/TIME.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EASTERN AND
CENTRAL MISSOURI AS WELL AS SOUTHWEST ILLINOIS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THUNDERSTORMS WILL BE LIKELY ACROSS AREAS NORTH OF INTERSTATE
70...WITH COVERAGE IN A MORE SCATTERED NATURE TO THE SOUTH...AS A
COLD FRONT ACROSS NORTHERN MISSOURI AND CENTRAL ILLINOIS
INTERSECTS VERY MOIST AND MODERATELY UNSTABLE AIR. SOME OF THE
STRONGER STORMS MAY APPROACH SEVERE LIMITS LATE THIS AFTERNOON AND EARLY
THIS EVENING...WITH GUSTS TO 50 MPH AND PEA SIZED HAIL POSSIBLE.

DUE TO THE STATIONARY NATURE OF THE FRONTAL BOUNDARY DRAPED ACROSS
OUR AREA AND THE HIGH LEVELS OF ATMOSPHERIC MOISTURE THAT EXIST...
THE HEAVY RAINFALL POTENTIAL WILL BE HEIGHTENED TONIGHT FOR AREAS
ROUGHLY ALONG AND NORTH OF INTERSTATE 70...WHERE RAINFALL TOTALS
IN EXCESS OF 2 INCHES WILL BE LOCALLY POSSIBLE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THE CHANCE FOR THUNDERSTORMS WILL CONTINUE THROUGH EARLY WEDNESDAY
AS THE FRONTAL BOUNDARY WILL LINGER ACROSS OUR REGION THROUGH THAT
TIME. ANOTHER COLD FRONT WILL APPROACH OUR REGION BY LATE WEEK...
WITH THE CHANCE FOR THUNDERSTORMS RETURNING BY LATE THURSDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED THROUGH TONIGHT. SPOTTERS ARE
ENCOURAGED TO REPORT HEAVY RAINFALL TO THE NATIONAL WEATHER
SERVICE.
