THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF THE MISSOURI

.DAY ONE...TODAY AND TONIGHT.
SCATTERED THUNDERSTORMS WILL BE POSSIBLE THIS EVENING AND

NOT EXPECTED WITH THE PRIMARY HAZARDS BEING CLOUD TO GROUND
LIGHTNING...40 MPH DOWNBURST WINDS AND SMALL HAIL.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
THE LOW PRESSURE AREA WILL TRACK FROM THE PLAINS INTO THE OZARKS
AND EXIT INTO THE UPPER MIDWEST WEDNESDAY THROUGH FRIDAY. IF
ENOUGH DAYTIME HEATING CAN BE REALIZED WEDNESDAY AFTERNOON...SOME
THUNDERSTORMS COULD BECOME SEVERE WITH DAMAGING DOWNBURST WINDS
BEING THE PRIMARY HAZARD ACROSS SOUTHEAST KANSAS AND SOUTHWESTERN
MISSOURI. INITIAL RAIN TONIGHT INTO EARLY WEDNESDAY WILL MOISTEN
THE SOIL WHILE HIGHER RAINFALL RATES ARE EXPECTED WEDNESDAY
AFTERNOON INTO THURSDAY. THESE HEAVIER RAINSHOWERS WILL BRING THE
POTENTIAL OF FLASH FLOODING TO THE AREA LATE WEDNESDAY NIGHT INTO
THURSDAY.
PRECIPITATION IS EXPECTED TO TRANSITION FROM RAIN TO SNOW EARLY
THURSDAY EVENING INTO FRIDAY AS THE LOW DEPARTS NORTHEAST AND
COLDER AIR MOVES INTO THE AREA. SNOWFALL ACCUMULATION IS HIGHLY
DEPENDENT UPON THE TRACK OF THE LOW. AT THIS TIME...SNOW
ACCUMULATIONS ARE A LOW PROBABILITY WITH ANY ACCUMULATION
FAVORING AREAS NORTH AND NORTHWEST OF A CASSVILLE TO SPRINGFIELD
TO SALEM LINE.
STRONG NORTHWEST WINDS WILL PRODUCE WIND CHILLS IN THE SINGLE
DIGITS AND TEENS FRIDAY AND SATURDAY.
THE FORECAST TRACK OF THIS UPCOMING STORM REMAINS VARIABLE. IF
THE TRACK SHIFTS FARTHER TO THE SOUTH THIS WOULD BRING A GREATER
WINTER WEATHER IMPACT. THOSE WITH TRAVEL PLANS SHOULD CONTINUE TO
