THERE IS THE POTENTIAL FOR IN EXCESS OF 1 TO 2 INCHES OF TOTAL
RAINFALL ACROSS PORTIONS OF THE OUTLOOK AREA. WITH DORMANT VEGETATION
AND LARGELY FROZEN SOILS...THIS AMOUNT OF RAINFALL WOULD LEAD TO
EXCESS RUNOFF INTO AREA RIVERS AND STREAMS. THERE REMAINS SOME
UNCERTAINTY AS TO THE TOTAL POSSIBLE RAINFALL AMOUNTS...AND AREAS
MOST LIKELY TO RECEIVE HEAVIER RAINFALL. HOWEVER AT THIS TIME...BIG
CREEK...BLACKWATER...SOUTH GRAND...PETITE SALINE...MONITEAU...AND

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL
AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT
AS OF EARLY AFTERNOON...TEMPERATURES HAD WARMED ABOVE FREEZING
ACROSS ALL BUT THE FAR NORTHWEST CORNER OF MISSOURI. DRIZZLE AND
RAIN...ALONG WITH AREAS OF FOG...ARE EXPECTED TO DEVELOP INTO THE
EVENING AND OVERNIGHT HOURS. TEMPERATURES MAY LINGER AT OR JUST
BELOW FREEZING ACROSS FAR NORTHWEST MISSOURI...INCLUDING TARKIO AND
MOUND CITY ALONG I-29...WHICH MAY RESULT IN SOME MINOR ICING.
FURTHER SOUTH AND EAST...RAIN ALONG WITH A FEW EMBEDDED
THUNDERSTORMS IS EXPECTED LATE TONIGHT. SEVERE WEATHER IS NOT
EXPECTED.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
EMBEDDED THUNDERSTORMS WILL BE POSSIBLE BOTH WEDNESDAY MORNING...AND
AGAIN WEDNESDAY NIGHT THROUGH THURSDAY MORNING...GENERALLY ALONG AND
SOUTH OF THE MISSOURI RIVER. NO SEVERE WEATHER IS EXPECTED. HOWEVER
ANY OF THE STORMS WOULD LIKELY CAUSE LOCALLY HEAVY RAINFALL. WITH
MUCH OF THE GROUND AT LEAST PARTIALLY FROZEN...ANY HEAVY RAINFALL
MAY QUICKLY LEAD TO FLOODING CONCERNS ON SMALLER RIVERS AND STREAMS.
LOCATIONS TOWARDS CENTRAL MISSOURI APPEAR MOST SUSCEPTIBLE TO
EXCESSIVE RAINFALL.
THE HEART OF THE STORM SYSTEM TO PASS INTO NORTHERN MISSOURI
THURSDAY EVENING. THIS SHOULD CAUSE A RAPID TRANSITION FROM RAIN TO
SNOW...FIRST OCCURRING OVER NORTHWEST MISSOURI AND EASTERN
KANSAS...THEN QUICKLY PROGRESSING EAST ACROSS THE ENTIRE OUTLOOK
AREA THURSDAY NIGHT AND EARLY FRIDAY. IT STILL APPEARS THAT THE BEST
POTENTIAL FOR HEAVY SNOW ACCUMULATIONS WILL FALL ACROSS ADJACENT
NEBRASKA AND IOWA...WITH LESSER ACCUMULATIONS ON THE ORDER OF AN
INCH OR TWO FROM EAST CENTRAL KANSAS THROUGH NORTHWEST MISSOURI.
PERIODIC SNOW SHOWERS MAY CONTINUE THROUGH THE DAY ON
FRIDAY...CONTRIBUTING TO ADDITIONAL MINOR ACCUMULATIONS.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED...HOWEVER REPORTS OF FREEZING
DRIZZLE AND FREEZING RAIN WOULD BE APPRECIATED TODAY AND TONIGHT. IN
ADDITION...SNOWFALL ACCUMULATIONS LATER THIS WEEK WOULD BE WELCOME.
